Our Most Recent Service Reviews

The system my dad has was installed back in 2010 by McCullough and they have serviced the system since then...I have always been more than satisfied...this specific service/repair event, even more so...the heating kit on the Auxiliary system was no longer working and a new one was ordered...this is the system in my 86 year old father's home, so his warmth is paramount to me...the new heat kit was faulty and the service tech and McCullough coordinated finding a replacement and searched the city and found one...all was completed by 1:30pm and well before the storm hit...my dad's home maintained a comfy 72 degrees...I am very thankful and appreciative... Update: McCullough just replaced the 20+ year HVAC system in my own home and I also cannot say enough good things about that experience...from the repair gentleman, to the sales tech to the install crew and then finally the quality control inspector...3rd experience with McCullough and I cannot recommend them highly enough...

Zach did a great job explaining my situation with me , was patient with all my questions , and there was a bunch and did a thorough exam of my system which is why I called to have done . Overall very good experience with McCullough . Definitely would recommend to others . Thanks

My AC went out on a Sunday afternoon I called McCullock Monday morning, scheduled Tuesday and had it repaired and running by mid afternoon Tuesday. Recommended a new system which honestly overdue. McCullock’s staff are always great!

Dillon was an excellent service person. He found the problem, quickly fixed it, and was extremely pleasant. I would request him every time if I was able to choose the person to do the work.

My AC stopped working last night. I called McCullough and they scheduled me with a technician the same day. Makayla was amazing. She explained to me what the issue was and without hesitation she got my unit back up and running while working in the rain. I highly recommend McCullough, I think I found my go to HVAC company!

Technicians are great. The fact that McCullough gives an all-day window for the technician to arrive is so 1980-ish. Even cable companies give you a 4-hour arrival window.

Makayla came prepared to repair a Freon line that was no longer properly insulated and did an excellent job. She was efficient in the repair and did an added diagnostic check of our air conditioner at no charge. She also took the time to recommend a commercial product for use in cleaning drain lines (instead of vinegar). Overall—well done.

AC tune up was performed and technicians were great in explaining what they were going to do and listened to my questions and concerns. Very professional

No complaints here. Got same day service when my unit went out. The repairman was courteous and knowledgeable. Fixed the problem quickly and I am very happy to be cool again. That’s what I call good service.

Sean with McCoullogh came out quickly to inspect the msg in our AC. He was friendly and provided good service!

AC ln my home compressor went out. It was replaced and is working great. McCullough it made go smoothly and at a great price. We are very pleased

We feel confident about the care of our HVAC system from Mc Cullough. Zack was punctual, thorough and answered any questions we had. Highly recommend.

She was very professional and knowledgeable

Very efficient office staff who quickly arranged for last minute night repair same day as problem started. Thomas Ischy repairman was fabulous, knowledgeable, so helpful. It doesn't get any better than this!

We are very pleased with the excellent service we received from McCullough! Highly recommend them.

Henry was very nice. Showed up on time and completed work in a timely manner and explained everything very well.

Eric did a great job! He was polite and professional. He got my AC up and running again in less than 30 minutes! I highly recommend Eric at McCullough!

We are very pleased with the excellent service we received from McCullough! Highly recommend them.

Was able to get my AC fixed after hours at reasonable price same day.

I have had today the AC verges by tech Desmond Lopez best technician very profession and knowledgeable knows what to do as quickly as he can. I am Very pleased with his service

After a diagnosis for a $3000 repair by another big, reputable Austin plumbing company, Charles Bryant came to give me another bid. He didn’t find any evidence of the repair being needed! He told me the processes he’d followed to come to that conclusion, and it all made total sense. He was professional and efficient. He ended up fixing the configuration of the drain line which was also done wrong by the other company. The repair of the drain line pea trap was more than I would normally expect to pay (I own rental houses so I have too much experience with repairs), but I have absolute 100% confidence that Charles did it correctly. Worth every penny!

Vlad is the absolute best. I had a previously bad experience and the team at McCullough offered a different tech to come back for free and make it right. Vlad not only spent HOURS checking every little detail, but gave me a personal phone call explaining his recommendations because I was not able to be there in person. He offered his personal cell phone and wrote an email with details and photos. Stellar job. Dude needs a raise!

Have used McCullough for about 2 years. Have found all their technicians and office staff to be professional, dependable and trustworthy. We have systems that are about 15 yrs old. And have made a few upgrades to help eliminate mold and dust concerns we’ve noticed, over all we found McCollough to be super informative and reasonable with their recommendations to address my concerns. Specifically, our technician Jaiden Mendez was super helpful and informative.

McCullough Heating & Air Conditioning provided great service. Jaiden was friendly, explained everything clearly, and answered all my questions. My outside unit wasn’t making any noise and the fan wasn’t moving. They replaced the capacitor, contactor, and hard start kit, and the pricing was fair. They came out very quickly on a Sunday morning, which I really appreciated in the Texas summer heat. The phone staff was also kind and helpful. My AC is working again and I’ll likely use them in the future when I finally replace the whole unit.

They were very responsive and friendly!

Makayla was awesome and did a great job for me.

Arrived quickly after late day call, found and fixed issue right away, much to my relief. Great company, responsive and easy to work with. Thank you!

McCullough has come through for us once again with high-quality, thorough service. This time our tech was Jaiden M. He showed great attention to detail and worked carefully to find the issue with our A/C unit. He communicated very well, keeping me posted all along the way. Jaiden also provided full documentation of the condition of the unit and his work. I'm so glad we have a service company we can count on!

This is a new review for McCullough. They recently came by to service my AC that was having issues. Charles was prompted, thorough, and explained his finding and fix in detail. I will definitely use McCullough and team for future AC repairs. Thanks!

Desmond Lopez of McCullough Heating and air gave us outstanding service when our air conditioner was failing. He explained the issues clearly, and did not try to sell us anything. I really appreciate the expert knowledge and honesty. Thank you McCullough Heating and Air.

I gathered quite a bit of information to get balanced comparisons and McCullough's offer came out ahead. Also the salesperson was extremely communicative and worked with us to get what we needed and wanted. Now 5 years later I stand by my review then, giving a 5 to Naser who came out to service our unit and make sure it could handle the excessive heat! Thanks McCullough!!!

I had some roof rats up in my attic and they did some damage up there and to the lines outside too (they chewed through to gain access to my garage and attic). And on top of that, the installation of my a/c unit was NOT done properly by the company that did it ten years ago. Henry found some issues that was causing demonstrable stress and damage to my unit that would shorten the life and gave me a reasonable quote to fix it all in one visit. Thanks!!

McCullough was quick to schedule and respond to our AC call. Easy to schedule online and Charles Bryant was checking out our unit less than 12 hours later. He found the issue, was honest and transparent, and fixed it for us quickly. Highly recommend McCullough and Charles!

Nasar did a thorough job on the A/c system He checked everything up in the attic. Had my Ac up and running again.

First time customer. Super impressed with the customer service and service guy was knowledgeable and provided great information and advice for the upkeep of my unit.

They got me up and running quickly in August.

These guys are fantastic! My husband and I are renovating an old house and when our AC stopped working, we braced ourselves for a very large unplanned expense. Dillon and his partner were able to come out the very next day and fixed the issue within 15 minutes! He saved us a ton of money & heartache, and even showed us how to prevent the issue in the future with regular maintenance. Their prices are very affordable and we will definitely be calling them again.

Naser was friendly, honest, thorough and fair. We have been very happy with McCullough and their customer service. We have had great interactions with everyone, including those answering the phones, performing the audit and installing our new system. We love that it is a family owned business and highly recommend them.

I have had today the AC verges by tech Desmond Lopez best technician very profession and knowledgeable knows what to do as quickly as he can. I am Very pleased with his service

They were very responsive and friendly!

Junior, my technician, came in and quickly tested my unit and diagnosed the problem. The day before I had a company in and they spent 3 hours. Said no heating element was out. Still no heat. Charged me $200 and left. Said some wires needed to be replaced! How wrong he was!! Junior found 3 heating elements out and said a pipe had been disconnected and never reconnected by previous tech. Junior is very knowledgable, kind and easy to understand. Thank you McCullough for your reputable, dependable company. Junior deserves a raise. 😃

The technicians were on time and assessed the problem quickly. Most of the work was completed that same day within an hour. We have two units and it was determined that one needed a full replacement. They were very helpful in offering options.

Service is outstanding. They are true to their word and do not try to sell you on things, which I appreciate.

Josh quickly figured out the problem and got our ac up and running. He also took the time to explain the repair options in detail which was very helpful. I will definitely use Josh / McCullough again!

Right on time. Professional. We would use this company again and again

Wow! Didn’t think I could be this happy with an AC company. Honest, truthworthy, and upfront about pricing. Henry went above and beyond to get our AC working in time to put our kids to bed. I can’t recommend them enough - very happy customer!

My HVAC died on a Sunday night and I called McCullough based on reviews. And here’s mine: called Monday morning, got my HVAC inspected, then sales came out to talk to me to pick a new one—then it was installed on Tuesday. Amazing!! And every single interaction with McCullough employees has been exceptionally positive. Shout out to Alex who helped me pick out an AC and didn’t try to upsell me. He was a great communicator and took into account not just my home size, but my personal budget. And the installers, Richard and Arthur, were fantastic. They were friendly, respectful, and clearly care about the integrity of their work. And after working 12 hours in the heat, they left my attic, home and yard spotless. That tells you a LOT. I would give McCullough 10 stars if I could!! Thanks, guys! Appreciate you!!

Stellar company to work with. I had 3 different companies come out and felt oversold.. working with these guys has been so comforting. AC is no joke in Texas and worth having someone who cares- that was this team. Makayla was amazing. Thorough and obviously very knowledgeable, she stayed to answer all of my questions and help us weigh the decision of repair vs. replace. Then the PM Peter came out same day (within 20 mins) to eval our tricky unit and worked hard to get options. Class act!!! I signed on for the membership, that’s how much I trust them.

Tech Kyle sterling was extremely professional and nice to deal with. An asset to your company.

McCullough tech team (Shawn and Kyle) were very responsive, professional and good follow through on diagnosing and repairing the problem with my AC fast. I appreciate their service and support

Blake was awesome, super professional, did a fantastic job and gave me great tips on maintaining my AC system. Great service. Thank you.

McCullough did a fantastic job installing a new GE heat pump in our upstairs area. Richard and Arthur were respectful and courteous. Thanks McCullough!

Fast service. Quick response. The AC Tech Sean C. fixed a complicated issue that a different company caused. Sean said he could have the control board installed and AC running the same day and he came through big time and saved the day and summer. It was 103 degrees that day. Next time I am calling these guys first Sean had the part delivered and began work in under an hour. The same part that the other company said could take days to find. Sean replaced a burnt out control board then replaced other burnt out parts the other company left. Was not an easy fix . reverse engineering the previous company’s work that blew up about 5 different components/fuses. First time in 10 years my AC is quiet and doesn’t sound like the back of an airplane . no more burnt plastic smell. . No nonsense quick service! After the last company’s games it was nice to have straightforward answers and solutions. Recommend. Thanks.

Highly recommend - honest, on time, and convenient online appointment booking.

Shawn and Joel were professional and diligent in resolving the AC issue.

Josh did a great job. My A/C was struggling to keep up in the Texas heat, Josh showed up with his tools and a smile ( even though it clearly had been a very long day for him) - he methodically went through his maintenance check and eventually discovered a capacitor on its last leg ( compressor wasn’t coming on when it should have). Swapped it out and everything is working fine now. 10/10 for Josh and McCullough - highly recommend.

I have a service plan with McCullough HAC, and it is the best investment I have made for my HAC system. The AC stopped working, and with just one call, I got a next-day appointment. Matt, the technician, came right at the scheduled time, made a diagnosis, fixed the unit, and we were up and running in no time! Thanks, guys! UPDATE: Second visit, ditto on the above. Every technician is professionally trained (It shows!) Talking with confidence on the subject gives me peace of mind. New UPDATE—Summer 2025: A same-day appointment is settled! One of the benefits of having a service plan is the ability to count on professional technicians to solve our issues! Call McCulloch HAC!

I have had today the AC verges by tech Desmond Lopez best technician very profession and knowledgeable knows what to do as quickly as he can. I am Very pleased with his service

Shawn did a great job, he is very professional.

A great experience with Alex Stevens in sales and Bruce & Francisco who installed my new split-system. Alex worked at trying to get a price I could live with and answered all my questions. Bruce & Francisco were so professional and did a great job installing without any time being wasted. I'm glad I worked with McCullough Heating & Air!

Zach was very capable, professional and went above and beyond to check out my 2 AC units in a situation where I didn’t know where they were located in my new home. He was patient while locating them and was gracious about the difficulty accessing them in crawl space and attic without good lighting. Very resourceful and kind. On top of that he did this service visit at the end of a long day and was thorough and informative. Zach deserves recognition for exemplary service! My first experience with McCullough was very positive!

Makayla was our technician and seemed very knowledgeable. She was excellent at communicating every step of the way in checking for the cause of the problem with the a/c and in eventually replacing the compressor. She gets 5 stars. However this is a brand new Carrier unit that is less than three months old. This was the second time it broke. McCullough did send someone out quickly each time to check out our a/c which was much appreciated. Just wish the Carrier unit were better made. They don’t make them like they used to.

Disappointed with my recent experience. Poor communication, different answers depending on who I spoke with, and then a requirement to pay in full before services are completed. No thanks.

Replaced twenty-year-old AC system with new carrier system also replaced some duct work when old system was removed. Derek at McCullouth was very helpful and accommodating to my requirements. His team was very professional to work with and finished ahead of schedule even with the additional ducting being replacement. 6+yes after having both AC units replaced, I've had Great service from McCullough over te years. 6 yrs later: the technicians at McCullough that have been servicing my 2 AC units have done a very good job over the years.

Very professional. These guys are pros! Honest and affordable.

Very friendly and knowledgeable. I would highly recommend them.

Excellent maintenance service. Very friendly and professional folks from McColough. Appreciate the thorough check on our carrier system.

We had three A/C wish list items resolved easily and correctly by Shawn and the team. First, we had a humidity issue in our home and had a whole home dehumidifier installed (we love it). Second, we had the air intake for our unit evaluated and upsized. And third, our original metal ducting had old, deteriorating insulation so we had all the attic ducts re-wrapped and sealed up. We were really impressed with Shawn and the team. They were thorough, professional and helpful. It is obvious that McCullough has a team of folks with plenty of experience to get any job done correctly.

They were great, Makayla is excellent. Very professional and knowledgeable about the systems, and made helpful recommendations for lowering my utility bills on a go forward basis. I will definitely continue to use the company and would like her to be the point of contact for a winter check up.

Sean with McCullough was amazing. He worked hard and showed up fast in this Texas heat. He was very patient in explaining what went wrong. They had the parts available on the truck to save time. Will definitely use McCullough again!

Dillon came on Sun. at about 6:30 pm. He was so nice and spent a lot of time diagnosing my problem. Im new with McCullough and have had a great experience with Henry and Dillon.

Josh did a nice job and explained our challenges clearly.

Great service as usual! Yay!!! Very polite and knowledgeable!!

Want to give a shout-out to Richard and Arthur for installing a new electrical/heat pump AC unit and an extra duct to our always-hot back bedroom. They did great work, especially considering the attic was 137° for awhile, but they stayed positive, professional, and worked hard. Thanks, guys!!

My AC fan went out late Tuesday night. They sent Josh out by Wednesday night. He had it up and running quickly. His truck was thankfully equipped with all the needed parts. He explained everything to me in layman’s terms so I could understand. He was very professional and courteous. He gets a definite 5 stars from me.

I love this company! My brother referred them to me, I used them in my and just used them again on my mother in Laws house. Every time they have worked with us, they have been very transparent and very honest with repairs, and most importantly, recommendations. If it does not need to be done, that is how it is explained, it is a “hey it would help, or might need it later, or it will help cool, but not a huge benefit” in short they show up and do the job they were called out to do, then discuss options. For example they pointed out our plenum (air distribution box) was undersized, (which is common in new houses to save money). It was a Potential overpressure point on the system. They quoted and recommended a new one. We did it, and it made a big difference in amount of air flow. We have had several companies up in our attic to work on the damper, do general maintenance and the like. Not one ever mentioned the size of our plenum. If you need hvac work done call these guys. They are prompt, fast, honest, and detail oriented. They will always be my first call moving forward.

Timely, professional service but expensive

I can't thank you all enough for helping us out diagnosing and correcting our issue so quickly. Jaiden was very honest and thorough, we now have some great working AC again. Will definitely utilize McCullough in the future!!

They checked everything. Hopefully solved the problem. Disappointed that I was charged a diagnostic fee for a unit that was about 7 months old. I hope this is not going to be a problem with Carrier air conditioners.

Henry quickly identified the problem, recommended and implemented the fix within one day during an emergency situation.

Shawn came out on the weekend and went above and beyond to service our ac on a very hot day. He seemed highly knowledgeable, and ran through a list of potential issues that he was going to investigate, found the problem, and then provided a thorough explanation of the issue and the fix. We highly recommend!

The crew that came out today, Dillon and Brian were absolute professionals and helped teach me what proactive steps I can take to keep everything running optimally.

The service was great! It was taken care of quickly. I appreciate your help!

Mitchell did a great job fixing the pump on my AC unit

Josh at McCullough did a great job at my rental property. He was prompt, courteous and assessed the problem quickly. I highly recommend Josh and the team at McCullough.

They were very helpful in replacing the needed piece as fast possible, and fixing our ac! Great work.

4.5/5 stars. First summer in our first home, and our AC was cutting off midday with no air reaching multiple rooms. We called a bunch of top companies beginning around Memorial Day, and McCullough was the only one to pick up the phone. Long story short, they concluded our system was ok, but our ductwork was shredded. Sales guy Pete came out same-day to issue a quote. He returned on a Saturday to measure vents and calculate heatload, and walked us through options for tackling a section of the house with no attic access. McCullough waited several weeks while we worked with a pest company to clear the attic, and then scheduled the work as soon as we said go. A crew came out and replaced all our ductwork and blew new insulation in one single day. Within 2 days, the system began short cycling (again), so we called back and McCullough sent Josh out next-day, who diagnosed a major drain clog, weak capacitor, and drain sensor failure and answered all my pesky questions about how to prevent clogs in the future. I question why all this didn’t come up during the initial diagnostics! Prepare for your issue to take multiple call-outs to fix and for things to cost a fortune (so you’re weary and give in to the maintenance plan?) but aside from that, they were super responsive, professional, flexible, upfront about challenges and structural limitations, and they ultimately did excellent, clean work in extraordinary heat to ensure we are comfortable in our home. If you need the pros, call them!

Thomas was very informative, and courteous. Did not feel pressured at all on choices for fixing my AC unit.

Our upstairs stopped cooling and we called McCullough after some friends had just used them. They showed up at their scheduled time and were able to diagnose the problem. They called about the warranty on my unit and unfortunately it had just run out in November. We had to wait a day to find the part and reschedule a technician to come back out for install. I recommend them and would use them again. UPDATE: The new compressor that the technician said I needed stopped working after 7 days. The technician who installed it mentioned it could stop cooling after 7-8 days and it could be a clogged filter. Thought this was a little odd but was glad to have cool air. After having this same technician come out 2 other times doing random things and trying to sell me services that were not needed we still did not have cool air. After the third phone call to have someone come out they finally recognized that maybe we needed a different person. They sent MATT DOWNING to my home and I cannot say enough good things about him and his work. He actually did a full diagnostic of my system, which the first technician never did. Unclogged a drain and replaced the filter the other technician said might be clogged, got the compressor working correctly (it never was and that filter should have been changed to begin with as part of the new system). He made sure that it was cold air blowing out of the vents before he left and communicated with me the entire time what was going on. He made what I thought were a couple of truthful recommendations and I was not charged for another service call. Before Matt came out I was never going to use McCullough again or refer them. I would have them service my system again now. It has been recommended that I would get better airflow if I put in new duct work. Current is 20 years old and disintegrated. Kyle Stirling came out and assessed everything. I agreed it was time and decided to move forward. Kyle was great to work with. Communicated well, very respectful and efficient. I feel confident in my choice and the work that was done.

Excellent company. Great service. Responsive and treat their customers with respect and care. I highly recommend.

Makayla took care of the problem very quickly. She was super polite and gave me some maintenance advice to use in the future.

Naser Berenji is top notch! He communicated his arrival time and arrived on time. He explained the issues clearly and provided recommendations. He fixed the issue and gave us a debrief on the work and associated cost. Very professional. (He was also really sweet to our dog!)

Vlad - very knowledgeable and gave great explanation with drawings and visually showing me the problem! McCullough is great and we don’t use any other company. We’ve tried others - some we would NEVER use again. McCullough is our go to for all 20 properties! Trustworthy, honest, and reliable.

Excellent work and courtesy service .well worth membership

Dillon did a great job. He showed up early and diagnosed my problem and help fix it in no time.

Vlad is amazing!

Josh quickly diagnosed a problem that three other technicians missed. I am so grateful!

Excellent work and courtesy service .well worth membership

Dillon and Bryan were great. We had the upstairs unit that failed (perhaps a storm voltage surge) and the upper floor was unlivable. Dillon was scheduled the next day and he diagnosed the issue, did research on the parts that needed replacement and had them to us in a few days. He brought Bryan with him a few days later and got the replacement boards installed and the unit up and running! Mcculough cares about getting you comfortable as quickly as possible and so I’ve been with them for years.

Josh did an awesome job diagnosing our HVAC issue , committed to a timeline and got the job done. Extremely reliable and very professional service

Professional service and staff. Courteous,responsive and friendly. Josh is an excellent asset to your company. Explains everything very well and l would highly recommend him.

Great, quick service. Eric is a pro!

Professional service and staff. Courteous,responsive and friendly.

Inspection fee is m$79

Makayla was amazing! She’s very professional, knowledgeable, and took time to explain everything to me. She was very thorough and cleaned up very well after herself. I highly recommend her and the guys at McCoulough.

Eric and Sebastian came and cleaned by backing up AC drain. Very professional and friendly. Would highly recommend them.

Dillon Revells helped us identify and fix an issue with our AC that we have been having off and on for years. We've had other people out and none of them actually got to the root of the problem until Dillon. He zeroed in on what was going on very quickly and wasn't afraid to get his hands dirty, literally, and dig through mud to solve the issue. We are extremely happy with the results.

Jaiden -technician - Was very knowledgeable technician. Gave recommendations for future consideration. Always prompt service and friendly staff. Everyone at McCullough is great. We have 17 rentals in Austin and they take care of them all!

Alonzo Olivas and McCullough Heating and Air Conditioning did an excellent job fixing my Carrier system. Alonzo was extremely thorough and detail oriented and did excellent work ! I will be going with McCullough from here on out!!

Mitchell is always personable and professional. McCullough has been doing a great job maintaining our system.

Sean was great, came out on a Sunday. I’ve called McCullogh before and I will call them next time I have an HVAC issue.

My boyfriend and I recently had our AC replaced by McCullough and couldn’t say enough good things about our experience. The project manager Evan was amazing to deal with. We had several companies come out and he was by far and away the most knowledgeable and straightforward. The crew did a great job with the install and were professional and tidy. We would not hesitate to recommend McCullough to anyone getting a new AC system.

They were great, Makayla is excellent. Very professional and knowledgeable about the systems, and made helpful recommendations for lowering my utility bills on a go forward basis. I will definitely continue to use the company and would like her to be the point of contact for a winter check up.

Vladimir identified and solved the problem quickly and was very nice and informative.

AC tech was friendly and professional. Checked out our AC system answered my questions and gave suggestions on how to keep drain pipe cleaned out.

Service was awesome!

Shawn May came out as our service tech. He provided options and shot me straight with possible costs for short term repairs VS a full replacement. I fully recommend these guys for your next AC need. This was the 2nd time using the company.

Makayla was incredibly professional, knowledgable, and thorough. She explained what she was doing during all steps of the repair and pointed out what we should be looking for and what tipped her off that the repair/replacement was needed. HVAC experiences can be rough - this one was fantastic and the cool air is flowing once again!

I had a routine a/c maintenance on my system. Vlad was very thorough and made sure I understood every step of the process. Love this company and their employees.

Nasser was on time, early actually, and very efficient. Since we are members of their annual program no charge for examining both out of order systems and fixing one.

Kyle came on a Sunday evening and diagnosed the problem. Thursday he installed new parts and we had good AC for the first time in a month. We were totally satisfied with the service and will definitely call McCullough the next time we need help.

Jaiden -technician - Was very knowledgeable technician. Gave recommendations for future consideration. Always prompt service and friendly staff. Everyone at McCullough is great. We have 17 rentals in Austin and they take care of them all!

I called for a regular inspection before summer and my experience was great my technician was Shawn may and he was very professional and show up at the time he said he would.

My AC fan went out late Tuesday night. They sent Josh out by Wednesday night. He had it up and running quickly. His truck was thankfully equipped with all the needed parts. He explained everything to me in layman’s terms so I could understand. He was very professional and courteous. He gets a definite 5 stars from me.

The lady was very helpful doing my HVAC inspection.

Henry was great! As always, McCullough provides the best service for home maintenance services that I’ve found in Austin. It’s not even close to other companies.

Consistent, friendly, but communication lacked a bit from home office. I had been bumped to my second appt. Guy showed up after hours, which was fine, Just expect them to arrive between scheduled allotted time

Tech Kyle sterling was extremely professional and nice to deal with. An asset to your company.

I had two visits, back to back, for small separate AC issues. The technicians were very kind and professional. I appreciated that nobody tried to upsell me on anything I didn’t need, and would recommend this company if you have any AC issues! (Also the people who answer the phones are helpful).

I have been with McCullough for almost 30 yrs in our home with 5 A/C units. They have always been there for us. Today, there came through again! Our largest A/C unit (under warranty) stopped working yesterday. I called Chris before 8 this morning (who sold this unit to me), frantic, as we were hosting a large birthday celebration in 2 days- eek! He immediately responded (even though he is not in the service area), and set me up with service managers and parts were quickly ordered, picked up, and installed in one afternoon. James, the service tech, came to my home, waited over an hour for the parts to be delivered here, and installed them quickly and I was up and running! Party saved! McCullough people are superstars and lifesavers! I would never use anyone else. Thank you, McCullough!

Professional and fast service. Eric diagnosed my failing A/C immediately, had replacement parts delivered that afternoon, and serviced it first thing in the morning. They took in my A/C warranty and only charged me for labor.

Joel @ McCullough helped us navigate an issue. He was professional and courteous throughout the process. The issue got resolved with is assistance. I would definitely recommend using McCullough!

Another McCullough maintenance visit that's left me with a smile. Visit was from Mr. V, a tech I hadn't met before, and the high quality service provided has resulted in me calling the office to compliment his work and request he be my primary tech in the future. Before leaving, he made sure I had no questions or concerns and he provided me with good advice on how to keep my system well functioning. I've been a pleased McCullough customer for over 15 years and I look forward to doing business with McCullough for many years to come.

Not keeping the time frame even if its whole.day. expensive diagnosis for.everything ,not fully satisfied yet.of their work

Absolutely professional, prompt, and the best at what they do. So happy with the commitment and service - amazing Technicians. Thanks Paul

Have used McCullough for about 2 years. Have found all their technicians and office staff to be professional, dependable and trustworthy. We have systems that are about 15 yrs old. And have made a few upgrades to help eliminate mold and dust concerns we’ve noticed, over all we found McCollough to be super informative and reasonable with their recommendations to address my concerns. Specifically, our technician Nick was super helpful and informative. They came out today to fix one of our a/c units kyle was great

I had a AC check up. The technician Jaiden did a great tune up and cleaned the unit nicely. Thank you 👍

They have been servicing our units for years and they are always very professional and very careful to not track dirt in our house they’ll always be servicing our units.

Fair, reliable, fast, and friendly service.

Vladimir identified and solved the problem quickly and was very nice and informative.

We had an issue with our AC on a Saturday morning, and Henry arrived 30 minutes after we called. He fixed the problem very quickly and we were back in business.

Alex gave us the most information and comparison of product choices of the three HVAC companies we received estimates from to replace our unit. The technicians were prompt and finished in less time than predicted. The follow up visit by Jimmy was as scheduled and his check revealed the WiFi thermostat needed to be replaced which he promptly scheduled for the following week. They took care of all the rebates and provided the information about the tax credit filing. Great business to deal with.

There are no words to express how great my experience was with each of the McCullough employees I worked with. All were professional, knowledgeable, caring, and HONEST. Even the ladies at the office went above and beyond my expectations by keeping me informed and registering my new unit for me. Great company to work with. Will recommend to anyone needing HVAC service. Make McCullough Heating & Air Conditioning your 1st choice!

This is the 2nd time we’ve had Henry come out to the house for service. He’s absolutely fantastic. He’s really nice, knowledgeable of his trade, and able to make innovate improvements on the fly. Highly recommend McCullough and Henry.

The McCullough technician did a great job. Very professional, very thorough, very articulate. Definitely 5-star service

Eric Suarez took excellent care of our hvac system and was very friendly/knowledgeable about the process!

Got me up and running quick!! Guillermo and Dillon were awesome

Nick went way beyond to repair my AC He did a great job. Thanks Nick Henry and Jarett are very knowledgeable and professional they quickly diagnosed the problem and fixed it. Im so happy that it was done so soon especially with the hot days of summer ahead. Im so relieved that my A/C unit is working properly again. Thank you guys for a 5 star job - Well done.

I'm not sure if there is such thing as HVAC intuition but Sean came and diagnosed a problem that I had spent 3000 dollars on so far with other companies. I never knew my house could be cool all day instead of constantly fluctuating. My unit was under warranty so Sean was able to get the parts free and installed things quickly. Great value and they have earned my business from now on.

Simple to understand pricing and service.

Mikayla was the best tech, I've ever had. Hands down the best.

The service was professional and thorough. My AC unit will be operating more efficiently. Thank you Jaiden

Technician Naser Berenji worked diligently to fix a major problem with my A/C system which cause the Ecobee thermostat to reboot repeatedly, thus not cooling my house enough. After several attempts, using various methods, he finally cleared the water drain line which had been clogging and causing the problem. I was very pleased with his work. Unfortunately, my A/C unit froze up the following day and has not been working since yesterday. That was discovered by another technician, Thomas Ischy, yesterday evening. He is scheduled to return today to finish the job. I'm awaiting him anxiously because I am burning up in my house and I need relief.

Absolutely professional, prompt, and the best at what they do. So happy with the commitment and service - amazing Technicians. Thanks Paul

Dillion as great! Very helpful, courteous, great attitude! Explained everything very clearly. Thx Dillion!

Great service from Dylan at McCullough Heating and AC. They were able to quickly schedule something for me. Dylan quickly diagnosed the problem and cleared a deeply clogged drainage hose. Amiable and professional service. Would recommend.

Great job fixing my air conditioner. Vladimir was a super technician! Being a Comfort Club member sure paid off! Fast service at a great price.

Dillon Revells is the BEST and I would give six (6) stars if I could! My drain line was clogged and it snapped at the attic unit. The threads to the fitting snapped in the attic unit. The sensor turned the system off and I needed help. McCullough sent Dillon to help me get the air going. The problem looked really bad. Dillon explained the situation and the possible costs to repair. It was a difficult looking situation to both he and I. Then, Dillon said he was going to try something radical. He went to his truck, got the tools he needed, and in less than 10 minutes was able to extract the broken threads and fix my broken line issue at minimal cost. Dillon then went outside and dug up my buried drain line and cleared it of the roots that clogged it. My weekend problem was fixed by Dillon in less than a half hour. If you want the best, please ask for Dillon. I am completely satisfied with the knowledge, work, workmanship, and professionalism of Dillon. McCullough is my choice service company and Dillon my choice technician.

Thomas did a great job on our mini-split. He knew what we needed, brought the part, installed it, and made another change that we suggested to prevent water releases from the unit. We are very happy with his work and his professionalism.

The most impressive thing about McCullough was the knowledge and professionalism of its technicians. The ease of customer service/scheduling department made the whole experience very easy as well. Not the cheapest option but for a reason, they deliver value in every interaction: phone, virtual, and in person. I was also in between travel for work and on a tight schedule. I had two technicians come out on separate occasions for the same issue, 1 to run a diagnostic and the other to conduct a leak detection and then replace the Evaporator Coil. I also had a sales rep come out to give me some options on replacing the entire unit. The sales rep was also technical and knew his stuff, he was very helpful in guiding me through understanding my options. At the end, the service manager not just replaced my evap coil for a reasonable price, but the technician helped me balance the outside unit, replaced the fan motor, and conducted other diagnostics included as part of the service. 5 stars all around.

Dillon was friendly and competent. He got my AC unit cooling again.

Buying a new HVAC unit is never fun, but working with McCullough made it way less stressful than I could’ve ever expected. From the first diagnostic tech that came out ( I can’t remember his name 🙁 ) to the install team and especially the project manager Evan, everyone was super kind, professional, and patient with all my questions. Evan helped me find the right unit without pushing anything on me, and made sure it was something that worked for my home and my budget. The install went smoothly, and even after everything was done, the McCullough team followed up just to make sure everything was running smoothly and I was satisfied with my new unit. What stood out to me the most was the level of care and the personal touch the McCullough team provided. You don’t get it everywhere. If you’re dealing with this Texas heat and need a tune up or a new system, call McCullough Heating & Air. Seriously. I couldn’t recommend them more!

McCullough and their technicians have been great to work with. They offered me options for repairing my system, had competitive quotes and were professional throughout the process.

Vladimir identified and solved the problem quickly and was very nice and informative.

I am a regular McCullough customer and have a maintenance service contract.with them, I like the work they have done and am comfortable doing business with them.

Kyle was super amazing, knowledgeable and extremely polite and professional!! He went above and beyond to sort out the issue that was occurring with our HVAC system! I will definitely recommendation him and McCullough to my friends and neighbors!

Thanks McCullough for a flawless smooth service. Alex S. led the way with helping pick out the best AC unit for my needs- the GE Connect variable speed - it is quiet, steady temp control and less humid in my house now. The team that put it all together and replaced duct work were also very professional and kind--thanks so much to Jordan, Ivan, Mark and Christian. Yall were awesome and worked so hard in hot temperatures. Lastly Jimmy came by 4-5 days later to do a quality check. Thanks, Jimmy. I will always call McCullough for any ac or heating needs i have.

Jaiden the techican was very through, respectful, courteous and clean after he was finished. however, communication from either he or the office or both could be improved, technician didn't arrive until 5:30.

Always happy with McCollough’s - HVAC technicians, especially Vlad Savinov, are well-trained, good communicators, and personable.

Fast and knowledgeable, Josh did a great job at explaining the issue and got it fixed quick.

I love this company! They put out real effort to get you scheduled for your routine maintenance, allowing flexibility to request either morning or afternoon service. Their technicians are friendly, polite and communicative., esp the one who came today! Nasar Barenji. He came early, was super nice, exceptionally competent and emphasized the critically important repair another one of McCullough’s routinely excellent technicians had recommended a year ago at my annual summer inspection that I could not afford at the time to authorize. They are all doing their best to help me extend the life of my aged HVAC system.

Henry is the best technician I ever met. He replaced our A/C compressor unit recently at my house. He did his best for making A/C works perfect without any problems. He even came back later evening for the unit to be completely dry. Now A/C works perfectly and even quieter and cooler. I am so happy with his work. Thank you Henry!

Mikael was the best tech, I've ever had. Hands down the best.

They have been servicing our units for years and they are always very professional and very careful to not track dirt in our house they’ll always be servicing our units.

We had a new air conditioning system installed. They were highly professional and did an excellent job. Financing was easy and they were polite and neat. Highly recommend.

Guillermo was our service tech today. He has been here before and this visit like his other visits have been exceptional. Friendly, professional and able to answer my questions completely. Highly recommend the team from McCullough.

Sean identified my problem immediately—a backed up drain pipe. He blew it out, poured in a cup of vinegar and advised me to dig out around the outside pipe and fill it with some pebbles or rocks. My thermostat is working again and I have a plan going forward. Thanks, Sean!

Kyle was super amazing, knowledgeable and extremely polite and professional!! He went above and beyond to sort out the issue that was occurring with our HVAC system! I will definitely recommendation him and McCullough to my friends and neighbors!

We replaced our HVAC with a system we purchased from McCullough Heating and Air. The crew worked hard to install everything in one day. They did a great job. Their manager followed up the next day and signed off on the system. Very professional crew, I highly recommend them to any one considering replacing or repairing your HVAC.

Scheduling online doesn’t have an option for ac tune up so when the tech came out he was a little perplexed that my AC worked. He said that tune up would take a long time and have to be rescheduled another time but he gladly took $80 to say my AC doesn’t need Freon after poking holes in my ductwork. He was friendly and informative though. Not $80 friendly but maybe $10 for gas friendly.

Fantastic service, professional and efficient. Their technician, Makaela, was quick to diagnose and repair my AC unit. I received all cost estimates before work started and was clear on additional work that could be done without making me feel pressured to have it done right away. I'm very satisfied with their work!

Great service! Really nice and honest people to work with.

This is now the third time I've used McCullough with a variety of problems for our aged AC system. This time the problem was bad enough we had to replace the entire system so we had the chance to interact with both the repair and installation sides of the company. Needless to say I was extremely satisfied with their service -- Our install team (Richard and Francisco) were absolutely amazing and worked non-stop all day in 90 degree heat to get us up and running. At this point I wouldn't trust anyone else with what I think is the most important utility here in Texas.

Only changed filter, but Eric came in with smile , on-time, and very personable with great attitude. Great Service Guy!

Dillon came out to check an issue. He was efficient and courteous. McCullough management was quick to respond to my problem without any hassle! Very appreciated. A shout out to Alex Stevens for coming to my rescue. What a great team!

It did not start off well, I waited from 8-5pm only to find the service man wasn't coming. I was rescheduled for the next day. They did apologize. And the service man came before noon. The service was good.

McCullough installed our hvac system several years ago, and we’ve had them come out a number of times to do maintenance checks and minor work. Very pleased with their work and advising us on taking care of our system

They responded that very same day when I called them and needed there service awesome!!

Great service from Dillon! Consistently happy with McCullough.

Dillon was awesome! He did a great job, explained all work in detail and answered every question I had.

Kyle was very helpful and informative.

Great and honest service!

Knowledgeable, friendly, courteous and competent.

McCullough is the gold standard as far as I am concerned. Tom Ischy was great, explained everything without "splaining" down to me. Just the facts Ma'am. From what I saw he works smart and efficiently, nice qualities in a Tech. If you need a new HVAC or repairs and service you can't beat McCullough! Honest, dependable, honor the warranty and everyone is so nice. My most recent McCullough experience: Friday13 sure lived up to its name for us. HVAC went out at about 11:30AM. I called McCullough as soon as I found the alerts in my email (maybe an hour later). Dispatch said they would try to have someone out by 5PM, but it was a busy day and the appointment was pushed back to 5P-8P. Tom Ischy showed up around 6PM and had the situation diagnosed by 6:20P. He explained the situation and was gone by 6:30PM. Unfortunately a part had shorted and fried, so it and its smart board would have to be ordered. I realized that since it was after hours the order would not be handled until Monday. The part arrived at my house on Tuesday. I called to schedule the repair. They were all set, waiting to hear from me and squeezed me into the schedule. Tom came out again around 6:20P, made the repair, reset everything and was gone, oh, maybe an hour or so later. We all did the happy dance and began closing windows and turning off fans as the house began to cool down. BTW the Comfort Club is a nice option.Yeah, it has a yearly or monthly charge, but from my experience is definitely worth it. Yay McCullough!

Fast, great service with friendly people

Prompt, polite, professional.

Guillermo, James, and the whole team at McCullough have been really great to work with! Truly. These are caring men and women who value helping others stay safe and healthy even with their air and systems in their homes. We are so grateful for their help and would recommend them to anyone looking for a high quality company and employees to work with. Thank you McCullough team!!! Our family has been taken care of so well and we are safe in our homes thanks to you all.
