I was appreciative of Matt sharing his expertise through his explanations of my heat pump system. I now have a better sense of the current state of my system and what to expect in the near future.

Matt is extremely knowledgeable. He is thorough and does not waste time. He explains what is being done in a way that customers can understand. McCullough has always been on time with the schedule we agree on.

Can't say enough good about this company! Had them install a new heat pump unit for AC/Heat in October 2024. Jensen Sexton came out and gave me a qoute for a Carrier unit that was well below all others by $6k plus after rebates. Turns out there was going to be a refrigerant swap on January 1st 2025 that obsoleted some units that were in every sense of the word TOP OF THE LINE! After their rebates, the unit I got was over $6000 less then all competetors. He and the team came out and in one day cut in an extra vent that even my picky wife swears looks like it always existed in our hallway and replaced the old one/installed everything new before 3pm!!! City inspector came out 3 days later and passed the install no questions asked.... Here's where McCullough and Mr. Sexton absolutely shined - the unit had a miniscule leak. Something that the factory, they themselves, and even the city inspector missed. One day the unit was working fine, the next I couldn't get it to cool at all. This was a Sunday morning/afternoon when it failed. I emailed them at 4pm on a Sunday expecting a Monday reply earliest...Nope! Jensen returned my email within an hour and came out the next day at 11am! After a quick inspection he found the issue by noticing a small oil leak on the base. His exact response that next day was "Do you want it repaired or replaced?" I was confused and asked for clarity. He stated "We want you totally satisfied, so if you're not comfortable with us fixing it, we'll give you a totally new unit." I was floored! No one I've ever dealt with was so upright with their choices! Asked him what the repair would entail, a simple solder job, so I said go for it. That was 3 months ago and I can't say enough good about the work/unit I got from them! This now fully repaired and functional system absolutely sips power! We've recently gotten down to 21° and the display reads "Heat Pump Heating" even though I switched it to "System Choice" to allow heat pump or heat coil usage....My bills have been well below the old gas furnace unit by double digits! To Top it all off - couple days after they installed it, we got a call from Tiff's Treats for a delivery. Was McCullough thanking us for our business! Give these guys a call and give them your job! You will not be disappointed! If you go with anyone else it's entirely at your peril of losing out on doing business with one of Central Texas's greatest businesses ever!!!!
