Our Most Recent Service Reviews

Miko did a phenomenal job with our semi-annual preventative maintenance. He was thorough, shared feedback as he worked through it, and explained potential issues and how they could be resolved. Outstanding job!

Tech was timely, polite and efficient. Did a good job and educated me on cleaning the drain line.

Blake was great and checked out my system. He was on time, which was great with my work schedule and he even changed my filter and flushed the drain with vinegar for me.

The best AC repair experience I have ever had. Easy online scheduling, quick call back to see if I was interested in a quicker appointment, great communication via text throughout, and Zach was phenomenal

Second time I've used this year. Very satisfied.

Always great service, dependable, and professional.

Amazing service! Josh came out and checked on a condensation line leak and was able to diagnose the problem right away. Glad we have been members to get such great regular service!

Blake did a excellent job!! He was very informative and answered all my questions. He also was very nice and polite!! I give him a 10 out of 10!!

Thomas Is hy was excellent. Highly professional and costumer oriented. We signed up for the premium maintenance plan, and looking forward see any of there technicians again.

Service was performed at scheduled time, technician examined both the outside unit and the condenser inside. Lines were flushed and outside unit coils were cleaned. The service performed was explained. I was very satisfied with the service.

The cement connecting the furnace to the AC vents was leaking air in the attic and he put a mesh and tape and cement that sealed it. Eric did a great job!

Miko was a professional, courteous, knowledgeable, and didn’t rush the service job. McCullough is one of those big names you can trust.

Great and honest service! Craig was very professional and informative. We will definitely continue our business with McCullough.

Eric was amazing. He explained everything step-by-step, was friendly, and took care of the issue pretty quickly! A1 service. Miko came to do our maintenance today. Excellent experience again! He was prompt, friendly and detailed!!!

Evan Young and the team at McCullough Heating & Air truly saved us! When the HVAC unit that cools all the bedrooms in our home went out unexpectedly, my kids’ rooms reached over 80 degrees in less than 24 hours. We called Evan in a panic and he immediately got on the horn with his office to see what he could do. We had planned to replace our other A/C unit sometime this year, so it made sense to replace both at the same time if possible. Unbelievably, Evan found two teams that could work on replacing both units for us the very next day. They arrived on time, calling us when they were about 30 minutes out so we knew they were on their way (always appreciated). Everyone on the team was incredibly kind and I especially appreciated how hard they worked to keep our home clean and free from debris as they worked in our attic and garage. Evan also came to our home during installation to make sure everything was going well and see if we had any questions. The crews were worked so hard, in the heat, to ensure they could complete the job same day. Both units are working even better than expected (glad we decided on the two stage systems) - our house has never gotten cool so fast or so quietly before! I wish we’d reached out to McCullough even sooner to get this done, but we are forever loyal customers after all the courtesy and hard work they’ve shown us.

Miko showed up on time and quickly proceeded to do preventative maintenance on our hvac system. Afterwards he reviewed what he had done and answered all my questions. Miko is a great technition.

Blake came out for our annual inspection and was timely, thorough and respectful! So grateful for a fantastic experience!

Miko was amazing. McCullough had installed my years back and I hadn’t been having them service it but I’m so thankful that I switched back. The technician was very knowledgeable and had fabulous Customer Service. I will definitely be using them from now on.

We had Alvin out to service our house and couldn’t recommend him enough. After taking care of our initial request he took the time out of his day to show us preventative measures as we had recently moved into the house. Fantastic service and will definitely be going back for HVAC needs. Also appreciate the care Blake showed during our annual inspection!

Christopher Miko thoroughly checked our ac/heating units. He answered all my questions too.

Love my semiannual checkups on my very old HVAC. Jaiden took his time and gave me a great checkup. Thank you

Just had my summer AC check by McCullough. Miko did a very thorough job and was also friendly and on time. He did a great job reviewing his findings and offered an upgrade for me to consider. I didn’t feel any pressure with the upgrade suggestion. I’ll continue using McCullough for all my HVAC needs.

Miko was terrific! On time, thorough and professional. Been with McCullough 15+ years.

McCullough did a great job servicing our equipment. Our technician Miko thoroughly explained all items and was responsive to all of our questions.

Blake called in early in the my scheduled window, was fast, efficient and nice guy. Highly rec McCullough.

I don’t write many reviews, but I felt this one was deserved. Last year, I had a complete HVAC replacement done. To be completely transparent, the process wasn’t perfect from day one. The original system that was installed ended up needing to be replaced. However, what impressed me most was not that everything went flawlessly—it’s how the company handled the situation when things didn’t go as planned. William (owner), Shelton (GM), and James (Service Manager) all got involved and stood behind their work. They never disappeared, never made excuses, and ultimately made things right. That level of accountability is becoming harder and harder to find these days. Since the replacement, the system has performed flawlessly. It has now survived almost a full year, including a Texas summer and winter. Considering Texas weather can go from “surface of the sun” to “why is there ice on my windshield?” in the same year, I’d say the system has officially passed its stress test. A special shoutout to James, who has been absolutely outstanding. Even after the installation was complete, he remained responsive, helpful, and genuinely cared about making sure everything was working as expected. That kind of customer service is rare. Anyone can look good when everything goes perfectly. The true test of a company is how they respond when something goes wrong. In my case, they stood behind their work, took ownership, and earned my trust. Thank you, William, Shelton, and James. I appreciate everything you did.

A tech from another company, told us the coolant was low and the pressure was dropping indicating a leak. Just finding the leak with dye and more coolant was going to cost $1500 and if serious a new unit would cost upward of $10 K despite our unit only 6 yrs old. After waiting three days to get a follow up visit, we gave up and decided to call McCullough. So glad we did. We had to wait two hours past our service "window," but the office and Shawn kept us informed about the delay. Shawn was very professional and asked about experience, wondered why the other tech did not think that a Lennox warranty for parts wouldn't apply, and then checked the pressure on the unit which was in a good range. He double checked the furnace and the thermostat, but finding no issues or indications that a problem had occurred, assured us that the unit was working fine. We were out only the $79 service fee. Shawn left us his number, but assured us that we could also call McCullough if something went south, but he doubted we'd have any problem. He suspected that the other tech's testing unit had malfunctioned and he didn't have the experience to mistrust it. Next time we'll call McCullough first.

Eric was extremely friendly and helpful. He explained each step in the process and was extremely professional.

Blake was prompt, efficient and polite. Good service, and he remembered my dog's name! Thanks

Ryan was very helpful and answered all of my questions. I recommend him!

Blake was awesome and did a great job for me. He took good care of us.

They did a great job on rebuilding plenums, running a few duct runs, fogging the system and repiping some HVAC pipes around the house, Marc, Chris, Ricky.

Miko was very thorough and great to work with. Knowledgeable and courteous. Hard combination to find lately. Am glad to join their comfort plan too. I think I’ll be in good hands going forward.

Miko came out today and was awesome as usual. McCullough always takes care of things and is super diligent with keeping our systems in order. Highly recommend.

Miko was terrific! On time, thorough and professional. Been with McCullough 15+ years.

As usual, they were prompt, professional, courteous, and supremely competent. Ryan was neat, well equipped, and on time. Communication about the appointment and arrival was smooth and seamless. I had them install my two systems and would do so again. This is a well-run company with excellent employees!

Blake was awesome! He was efficient and thorough!

From beginning to completion of the task my experience with McCullough Heating and Air Conditioning was positive. I especially applaud Christopher, the tech. He is a man of integrity and competence.

Super impressed with this whole team. They were extremely thorough during the initial service call, checking my indoor unit, the AC unit outside, and ductwork. They showed me photos and explained exactly what the problem was, what caused it, and answered all my questions. I felt like they were honest about what was needed and gave a competitive price. I ended up needing to replace my ductwork and they were great from start to finish. They sent someone out to measure and make sure I got an accurate quote. The team that did the ducting was on time, respectful, and cleaned up after themselves. And, my AC is working great now! Thanks McCullough for making something stressful much easier on me.

McCullough did a great job with the installation and went above and beyond in working with our schedule. They showed & talked us through all the information we needed to know about our new A/C and HVAC systems.

I'm really happy to write a very positive review for Kyle Stirling, who provided my first seasonal a/c checkup last week since purchasing a new a/c and heater from McCullough last December. Kyle was not the technician who had been scheduled to do the checkup but, when that person was delayed by a much-longer-than anticipated appointment earlier in the day, Kyle stepped in in his place. I am so glad he did. He was so thorough in his inspection! When Kyle spent more time outside than I've ever experienced inspecting /testing the equipment, I asked him if all was okay, and he explained that my a/c had been installed on a cool day in early December 2025 and he wanted to make sure the equipment was calibrated as it should be (my layman understanding of what he said). Kyle, thank you so much for your expertise, professional/kind demeanor and thorough first seasonal inspection of my new a/c with McCullough!

Professional and punctual. Very thorough and a nice respectful technician.

Technician was prompt, knowledgeable, friendly and fast. Very satisfied.

Competent technician. Arrived on time and serviced our unit expertly.THANKS!

Eric was great. He came when he said he’d come. He gave me all the details of what was going on to make sure I understood plus make sure my hvac was functioning properly

Miko was very nice informative explained exactly all he did excellent service

The HVAC technician Shawn May was very efficient and helpful. He clearly knew what he was doing, and he was very polite and friendly.

Jaiden is a great tech. Professional and prompt.

Very knowledgeable about HVAC systems and actually opened plenum to confirm no mold present. Advised purification system.

Henry came to the rescue to fix a problem created during the original installation six weeks ago of a new 3 ton system. He came Thursday afternoon to resolve it so I wouldn’t have to go the weekend without cool air in my kitchen and family room.

I always have great experience with McCullough Heating and Air! Josh was fast and accurate in diagnosing and fixing my issue with my air-conditioning. Thank you again!

Competent technician. Arrived on time and serviced our unit expertly.THANKS!

I am so happy with my decision to have McCullough replace and install my new HVAC system!! I so appreciated Evan coming out the day I called to assess my needs and make recommendations. He took photos of my old system and showed me what he based his recommendations upon. Once I signed the estimate (very reasonable) he was able to schedule 2 days later. The installers, Ivan and Ricardo, were rock stars!! Showed up at 8:30am and left at 8pm. They patiently answered every question, explained all aspects of their work, were kind to my cat! , were considerate of my home, cleaned up after themselves and were so professional and nice. They just went above and beyond to provide a great service! Good job team McCullough!

Miko was very nice informative explained exactly all he did excellent service

Miko did an excellent and thorough job with the maintenance of our AC unit, as part of our maintenance plan. He checked the performance of our system carefully and identified an issue with the condenser coil and provided estimate after verifying that parts are covered under warranty. He also pointed out a location where the filter should be replaced which our previous AC company never identified. We are glad that we switched to McCllough for our AC needs!

McCullough Heating & Air is fantastic! Their service technicians are always friendly, knowledgeable, and helpful. We recently had Mike complete our service visit, and he was excellent. We will definitely be requesting him again in the future. Go Big Red! 😁

Kyle came quickly and worked efficiently. He is a really respectful guy and great at his job! Thanks for fixing our HVAC y’all! Update: Thomas came out and was so friendly and very thorough. Thanks Thomas!! In my previous review I did not include what had been fixed. They patched a busted Freon line and refilled my Freon. Today’s call was because my AC stopped blowing cold slowly over a couple of days so I figured it might be a leak from the patch that they had previously placed. It was. And they handled it perfectly, coming out quickly, checking the system. Discovering it was a leak from their previous repair, (NBD, sometimes that stuff just happens and it’s all about how it’s dealt with) They offer a two-year warranty on their repair work, and they stuck to that without any pushback or trouble. Thanks you guys. Y’all are a stand-up business, and I appreciate that!

Blake was professional and kind; highly recommend.

Sean is our hero! Very friendly and knowledgeable. He saved our Memorial Day weekend!

Sean was an absolute LIFESAVER! Our thermostat was on the fritz on a hot day. After a broken thermostat diagnosis, he had a courier deliver the thermostat within an hour. He left to handle another call and then came back to fix our unit after the thermostat was delivered. We truly appreciate the effort. 🙏

Knew what he was doing. Kind and considerate.

We had two nation-wide companies work on our A/C, but were still having problems. We decided to switch over to local folks, so we called McCullough. They were prompt. Noah (the tech guy) found the problem and fixed it completely. Now the A/C blows cold, the compressor runs quietly, probably saving us from expensive future repairs. These guys are prompt, honest, and great to work with. Highest recommendation.

As always very professional, and honest company. Miko helped me today and I am very pleased with the service. Thank you!

Brett did an excellent job. He checked out my a/c units. I had new filters waiting for him and he replaced the old ones. He came with booties on and left everything as clean as it was before he arrived. He was professional, pleasant and thorough. This was part of the annual maintenance done as part of the maintenance plan.

Junior De Jesus was the best McCullough service person we’ve had over the past few years. He was kind, courteous and one could see his experience, offering very helpful info. He also helped us program our EcoBee thermostats to our desired specs, and was kind enough to change out our whole house filters and carry away the used ones…. McCullough and Jesus are awesome!! Highly recommended!

Blake arrived early for our semi-annual AC/heater inspection and went right to work checking out the system functionality up in the attic, testing the thermostats, amount of refrigerant, filter conditions, etc. He was very thorough and spent close to an hour checking and testing our entire cooling and heating system. The best part? He reported that everything was functioning smoothly with no issues and nothing in need of repair. We've used McCullough in the past and appreciate their thoroughness and employee honesty. I highly recommend them for HVAC inspections, repair or replacement.

Miko did an excellent job with our AC tune-up today. He answered all my questions and provided helpful recommendations. Highly recommend!

Love the McCullough people!

I had a service visit from Guillermo today. He was on time, super courteous, very knowledgeable and through ability what was being performed. I highly recommend him to anyone needing assistance

Jaiden did a great job with a maintenance check at our rental property. Very professional, friendly, and knowledgeable. He found an issue and he sent estimates with recommendations what was needed. We recommend McCullough !

Very experienced

Technician was on time and there were no issues. Thanks!

Blake came down for our subscription plan maintenance and was quick, efficient, and informative. Thank you!

Working with Miko from the McCullough Heating & Air team was a fantastic experience. It’s hard to find an honest and friendly HVAC technician. I highly recommend Miko at McCullough for your Heating and Air maintenance. In terms of a complete HVAC replacement, I would consider other companies as their pricing is quite high.

Mico did a great job polite friendly and informative.

I wanted to leave a review because McCullough has taken such great care of me over the years. They installed my Heat/AC unit about seven years ago, and I’ve been extremely happy with both the system and their seasonal service checks. Christopher Miko was especially wonderful during his recent visit — very thorough and professional. I truly appreciate all of you and will continue to recommend McCullough Heating and Air to anyone who needs reliable, top‑notch service.

Miko was awesome, very thorough and plain spoken about what he was checking and cleaning

I am on the bi-yearly maintained check and Blake the technician explained everything to me. Blake was a fantastic service rep. Thank you Blake.

Miko was very professional and knowledgeable. He was very efficient with the service and provided guidance on selecting the right filter. I’d recommend McCullough to anyone needing service or a new AC.

Eric was great and very thorough. He asked about any concerns and really listened, nice and knowledgeable.

Blake was so awesome!! He was on time, professional and went above & beyond to make sure every inch of my unit was clean & working properly. Will definitely call on him again!! Thank you Blake!!

Blake was phenomenal! Friendly, professional, and made sure I had the right filter size to help us stay cool through a Texas summer. Could not recommend more!

Blake did a wonderful job!

Blake with McCullough is a courteous and professional young man. Great job Blake!

The technician, Christopher Miko, did an excellent job in servicing our systems. He was thorough and informative. Thank you for the expertise and professionalism!!

We have had two A/C units installed by them as well as all repairs & maintenance follow up work required. They have always been timely & professional when at our residence & rarely had to pay any repair costs due to the equipment being under warranty. I would recommend them to anyone needing a new unit or repairs.

Careful Installation, excellent advice on the choice of HVAC

Very knowledgeable friendly service.

Great experience. Keep up the great work! I’ll recommend you whenever I get the chance!

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

Quick scheduling, efficient service. AC vent pipe was clogged. Craig was great, appreciate the service

Very good experience with McCullough Team and their technician Ryan Lake. I had signed up with them for their Premier Comfort plan last month and AC was turning off randomly. Their tech came in at very short notice and cleared the drain system and AC started working. Just when it got hotter, the blower decided to fail so I contacted them. Tech came on a weekend, diagnosed the issue and put in a request for parts right away. I was dealing with am emergency situation at home and could not approve right away. Home warranty covered this expense but I did not have time to coordinate things. Once I got approval, they came and fixed it right away. I appreciate their promptness and response emails from their customer service manager when she heard about my predicament. The only tough part is getting a hold of someone to talk to. 'Jane' , the voice assistant is very smart and responsive but takes a few tries to tell her that a human being is required. All in all a great experience - I would highly recommend this company for taking care of heating and cooling equipment.

Blake performed our summer maintenance and did an excellent job. He was on time, thorough and took his time to complete the job to our perfect satisfaction. Highly recommend.

Thank you so much for the AC maintenance, Blake! Very quick and system is running great!

Great attention to detail !

Guillermo took good care of us. He was professional, informative, and experienced.

The technician was courteous and professional and answered all my questions. My only gripe is with the scheduling of the company. I wish they could better narrow down arrival time to either morning or afternoon.

Miko completed a very thorough check of our system today. We’ve been satisfied with McCullough for years.

Been a happy customer for 5 years and had 2 service appointments with Joey and Clayton this week. 2 hours superb service on the first visit for annual service check-up and an amazing education on our system. These guys are upper management and pros! Clayton came back and spent 3 hours to expertly install 2 top of the line surge protectors for our AC and Heating systems. Reasonably priced. Simply our best service experience with a company EVER!! Highly recommend. Thanks McCullough!

Ivan and Ricardo arrived on time and ready to complete the job. They were obviously knowledgeable, and quite professional. They did not make a mess and cleaned up behind themselves. Therefore they accomplished the second most important job that day, they passed the "wife test". She was thrilled at the way they went about their work, and the way they cleaned up. In the future McCullough will always be our first phone call.

Excellent service. Can really tell the employees enjoy working for this company

Great and timely service today ! Bryan did a great job. Thank you.

Blake was awesome. Efficient yet comprehensive, polite and courteous. Would recommend McCullough and Blake!

Great company! Jaiden is fantastic! Professional and knowledgeable!

Blake was great. He was very efficient, on time and even wore shoe covers.

Blake came to do an inspection and was awesome! he was quick and professional, made me feel confident in my system making it through another summer.

Miko did an excellent job on our summer AC tune-up. He arrived on time, communicated clearly throughout the visit, and was both friendly and professional. He worked efficiently, made practical and honest recommendations, and took the time to explain everything in a way that made sense. Really appreciated the quality of service and attention to detail.

Blake is great!!! Thank you so much

Great experience working with McCullough. Able to easily schedule and appointment online and add notes and get updates through their automated call service, which was surprisingly easy to use and always available. Our Tech, Craig, was helpful and guided us through the decision making process on the repair without feeling pressured or feeling like we were being up sold.

We had an outstanding experience with our HVAC technician Miko. ,He was extremely thorough and took the time to make sure the airflow throughout our home was being distributed as evenly and efficiently as possible. What really stood out was how he advocated to the owner about the importance of fixing an issue that had previously been overlooked. His professionalism, attention to detail, and genuine care for doing the job right truly set him apart. It’s rare to find someone who combines exceptional technical knowledge with such strong customer service and personal integrity. We really appreciated his honesty, communication, and dedication to making sure everything was handled properly. Highly recommend Miko!

Great service call today by Miko. Very informative and helpful

Great service as always!

Cannot speak highly enough about McCullough! Just had a great check up with Blake, and he was very professional, nice, and knowledgeable. We get consistently great service from McCullough and can always trust they'll keep us cool in this Texas heat!

McCullough Heating and AC provided professional and courteous service every step of the way. They coordinated with the City of Austin very well. We were very pleased with the installation of our new system.

Henry did a great job and he was friendly plus courteous!

We have McCullough perform regular maintenance checks on our system. They are knowledgeable, dependable and honest. Blake was our most recent technician and he was very professional, careful and friendly. We highly recommend them.

Craig came out to do my annual service. He came out at the beginning of the time window and was very courteous and knowledgeable. Excellent service!

Kyle did a great job with a maintenance checks on 2 of our rental properties. Very professional, friendly, and knowledgeable. He found an issue and he repaired it quickly. We recommend McCullough !

Blake did a great job with our semi annual HVAC check. He was on time, through and quick.

Miko arrived on time and was very professional. He did a thorough check of all of our units and explained everything to us in great detail. I would highly recommend Miko!

I wanted to share my experience with Henry Harris. Everything was great—Henry explained everything clearly and thoroughly. He was very polite, professional, and respectful throughout the process.

A sensor went out on the outside unit. Service was out the next day to diagnose the issue and then scheduled a return visit after the part was delivered to our house. Very satisfied with this level of service

A long-time Austin company that provides top notch value and service. The technician, Joshua, was the epitome of professionalism and just a great guy.

Mike was great and very committed!

Miko was clean, curious, and quick to get his work done(AC summer Tune-up). I’ve used McCullough 2 years since we bought our new ACs from them. Nothing but good news to report.

Very good experience all around. No complaints. Love that it’s a family run business!!

Blake was very thorough and professional. I was very satisfied with the service he provided.

Bryan Hermawan was excellent. He was courteous, knowledgeable and helpful. My A/C is now ready for summer and I have Bryan and McCullough’s to thank for that.

Big fan of McCullough. Blake was professional, thorough, and great to work with. Highly recommend.

Miko performed an annual service check on our systems. He was extremely professional, polite, and experienced. He was efficient in his work. He answered my questions and, in the end, saved me money.

Very polite and respectful. Knew what he was doing!!

Big thanks to Blake from McCullough Heating & Air Conditioning for the great service. He was professional, thorough with the system maintenance, and made sure everything was running perfectly. Highly recommend!

Miko was GREAT! Super professional and kind. Thanks for keeping us cool in TX!!

Miko came out today to perform an annual system check and flush on my HVAC system. He was friendly and efficient and explained everything thoroughly. Great service!

Great service experience with Shawn

We have been extremely pleased with McCullough Heating and Air Conditioning from the beginning. They came on a weekend to fix our AC and discovered it was old and not repairable. It was during a heat wave and they immediately brought a window unit to make it bearable until they could install our new unit. I highly recommend this company. All of the staff from the initial visit to completion were, friendly, courteous, professional and just top notch!

I just had our spring/summer maintenance check completed by Blake who provided an excellent professional system check. He worked very organized and cleanly in moving from inside our home to the HVAC units outside with a status update of our system.

Our service technician was outstanding! He took time to explain his process, and was extremely personable. Thank you Michael!

Very knowledgeable friendly service.

Kyle came to my house same day after unit failure. Very professional, courteous and competent. I am using them for my regular maintenance moving forward.

He was great !! And great manners !! Everything is working beautifully!!

Had puncture in refrigerant line, was great working with Craig who patiently guided. Hope the fix stay on..

Excellent,thorough maintenance on AC system

Wow, just, wow. Let me first say how glad I am that we canceled our First American Home Warranty. Last time we had an AC issue, we were out of service for three weeks due to a fight between First American and their local provider. ANYWAY: We found our AC out at 1am on Saturday August 10th. To my shock, when I called the 24hr number, someone answered. Then they committed to a tech visit later that day. At 10am Saturday, Mitchell called me on his way. 1030, Mitchell arrived and immediately diagnosed the fan motor as having failed. With the parts supplier closed for the weekend Mitchell committed to follow-up on Monday and installation ASAP. 10am Monday morning Mitchell called me on the way with the new motor. By noon Monday we had cool air blowing - that’s 2 1/2 days - I am SO stunned! Thank you so much McCullough and Mitchell!!

We were extremely happy with Ryan Lake's approach to resolving an issue with our Carrier system that 3 other companies could not. We felt he truly liked his job, unlike 3 different company's employees we had before.

Blake was extremely professional from start to finish. He kept me informed throughout the entire repair process and explained everything he was doing along the way. He was punctual, respectful of our home, and cleaned up thoroughly after the job was completed. I was very pleased with the service I received today and would absolutely recommend him to anyone needing HVAC work.

I’m a big fan of McCullough’s great tech staff. Everyone is knowledgeable, courteous & friendly. Henry was great today. McC’s has excellent admins who are not confused at all by my two accounts - a refreshing change from other AC services! Thanks so much, everyone. See y’all in autumn for the next seasonal check. (May 8 ‘26) Excellent experience with McCullough! I’ve been impressed with their good communication and top-notch service. Kudos to Myra, Michael and Ricky. Special shoutout to James for his keen observation/diagnostic skills, his knack for explaining things to clients, and his calm efficiency in tackling work at hand. I’m very pleased. Thank you! (2024)

If you are looking for best of both world - quality and cost, look no further!

Great Service! I needed a unit fixed ASAP and another checked. Called the service line and had a great automated experience. No waiting on hold. Booked a service call for next day and I was kept up to date by text. Kyle arrived and was very polite and methodical explaining what was needed and the cost. Very simple and he cleaned up after checking the units inside. So thanks for a great experience.

Happy with the system I bought and the price. The maintenance process with guys like Craig Plank Juarez is always a good experience.

Blake was an excellent technician He was a professional and answered all my questions. He was quick and thorough.

Awesome service! Clayton and Joey did a fantastic job yesterday during the maintenance visit. From the very first contact to the completion of the service, everything was absolutely perfect. They were professional, polite, thorough, and genuinely pleasant to work with. The service exceeded my expectations - I rarely write reviews, but this one was definitely worth it. Thank you so much!

Mico is professional and pleasant. Completed efficiently.

Miko & McCullough Heating and Air Conditioning, Inc. consistently provides the best service thanks to their team of professional employees.

Prompt efficient service. Friendly knowledgeable service technicians.

Chris Miko is a great tech, professional, efficient, friendly and very courteous. Arrived on time, paid attention to detail and offered maintenance tips, he appeared to have a vested interest in our unit. 👍🏻👍🏻👍🏻

This is the place to go. I was almost swindled by Honest AC. Craig did a great job and got me fixed for 5x less than the other guys. This is the one to pick.

Very responsive on service timing and very efficient and professional when they arrive. All of our experiences have been rock solid

Miko did an excellent job on maintenance of our 2 units. He is very knowledgeable and very thorough in his assessments. His advice and recommendations were very reasonable and appreciated. We would like to maintain continuity with Miko’s service.

Blake did a great job. Reviewed everything and asked questions to complete the job

Quick, thorough and professional. Been using them for years. Service performed like proffessionals.

Great visit Tom really knows his job. B

Craig did an outstanding job and explained everything he did in detail!! One of the BEST technicians that has serviced our home!! Hope he is being paid. well!!! We will request him in the fall to service our heater! Please share this review with him!

Always a great experience with McCullough, they are very professional and reasonably priced. Jaiden came out and went above and beyond on the recent visit to my property and helped me understand the issue and made scheduling follow ups easy. Always recommend this company when people ask for HVAC referrals.

Great and thorough work.

Comprehensive diagnostic, clear explanation of service and findings

We really needed help from McCullough in the past. Ever since we take advantage of the service every 6 months on the affordable monthly plan. Special thanks to Blake! I’ve trusted McCullough for over 20 years and highly recommend them.

Guillermo provided excellent service by quickly diagnosing the issue with my AC and completing the repair efficiently. He was professional, courteous, and took the time to clearly explain everything while ensuring the work area was left clean and the system was working properly.

Great experience getting our AC units checked for use this summer. Miko, the technician, was on time, very thorough and informative as to what he was doing. He is a credit to the McCullough service team.

Michael was a joy to work with. He was professional, friendly, and very capable. He quickly diagnosed and repaired or A/C unit. This was the best experience I have had with HVAC repair. I strongly recommend Michael and McCullough Heating and Air Conditioning.

Chris is outstanding!

Bryan Hermawan did a great job!

Thomas was great, he had our air-conditioning fixed in under an hour. He was a little delayed getting to our house, but it wasn’t his fault his work van had mechanical problems . I’m just glad he stuck to it.

Miko did a great job on our system yearly maintenance. Very polite and considerate of our home.

Changed copper line Between outside and inside units as it had a slow leak. Eric was just outstanding in his skill, manners and timeliness

Miko was great. Happy to have him out.

When our 5 ton Carrier unit stopped cooling, Michael Mctaggart got us up and running again. Skillful attention to detail!

There was an issue with the A/C after a recent repair by a different technician. Michael Mctaggart arrived the same day and had everything working perfectly again within two days including replacing parts that may have been damaged by the issue at no charge. McCullough took complete ownership for the issue and made it right.

The A/C squirrel cage fan had self destructed and blocked the blower motor with family visiting so we did an emergency service call to McCullough. Michael Mctaggart arrived the same day, diagnosed the issue, and then returned to replace the fan and blower motor. Everything is now working well thanks to his attention to detail and skill.

Thanks to Bryan for a thorough and professional checkup of our HVAC system.

Quick, efficient and super nice!

Miko was efficient very friendly courteous, and did an excellent job. I highly refer him.

Christopher Miko was the service tech that came over for to do the maintenance and he was very professional and thorough. I appreciate him taking the time to do a great job and answering all my questions. I am a new customer with McCullough and so far I am happy with the service I have received.

I highly recommend McCullough. I recently purchased a Carrier Infinity System with Greenspeed technology. I knew I wanted a variable speed system, but I had a lot of questions. Evan took the time to educate me on the technology, give me various options, and helped me make an informed decision without pressure. I got multiple bids, and ultimately McCullough was the best option. Our installers Ian and Ivan showed up on time, went over what they were going to do, and got everything done in a timely fashion. The system itself has been wonderful. The Infinity is so much quieter, and we can finally hear each other talking! Overall I'm satisfied with both the system and the service.

Great experience getting our AC units checked for use this summer. Miko, the technician, was on time, very thorough and informative as to what he was doing. He is a credit to the McCullough service team.

Great experience overall. Got me on the schedule the very next day, and Michael had my AC checked out and back to cooling within the hour, explaining the process as he went, and never trying to upsell me on anything I didn't need. Will 100% be coming back to McCullough if I have any other AC issues in the future.

Eric was very knowledgeable and extremely helpful with providing education and recommendations on what to do with our HVAC. Their phone AI system is the most advanced I’ve dealt with. Would definitely recommend this company

Eric Suarez ran a diagnostic evaluation of our a/c system, as requested. He was professional, amiable and well informed.

Josh explained the situation with our AC system thoroughly and was very prompt in getting the repair done. He has been to our home before and we are always very satisfied with his work.

I have been using McCullough Heating and Air to provide my twice yearly maintenance for nearly 3 years. During the last 2 months I have had my unit serviced by Vlad for a drain clog and recently Jared for my annual maintenance. Both technicians did a great job and spent time servicing my unit despite that it happened to be late in the day. Both were professional in their demeanor and engaging. I would have to say the same for the past technicians who have serviced my a/c unit. I would also offer that I have been impressed with the thorough maintenance service that McCullough provides,

Friendly and efficient maintenance service and well worth the maintenance fees.

Been using McCullough for a few years now, mostly just for annual maintenance. Staff is always helpful and responsive and pricing seems to be competitive. Blake has been my service tech a few times now and I really appreciate his professionalism and friendliness.

Miko was efficient very friendly courteous, and did an excellent job. I highly refer him.

Mike was talented, efficient, and professional.

Technician Miko was very thorough for AC annual check. Appreciate his advices as well.

McCullough has given us great service for many years. Today's (2026-04-27) summer season inspection was exceptional in attention to detail. In addition to all the required checks and settings, they hosed off the compressor. They concluded with a review of photos of all critical parts and their manufacturer-documented settings, compared to today's actual readings. They were within tolerance throughout. Thank you! Quick and efficient service, well explained. Update 2024-11-05, Joe was most helpful with a quick and thorough seasonal inspection. He also gave great advice on when to repair our now aging system.

Excellent maintenance service. Very friendly and professional folks from McColough. Appreciate the thorough check on our carrier system and ability to fix any issues right as summer temps start up. Thank you!!

Blake was great! Quick work and provided helpful information. I’ve had these guys come for the past 3 years to service my unit and he was the first one to mention that I can become a member for $11 a month and it will pay for the annual inspection I already have them do while also offering other long term benefits.

great, responsive and no complaints, got the ac tuned up
