Shawn did a fantastic job and thoroughly checked my heater And give me a report. He also had a couple of great recommendations for maintaining my unit properly. ___________ In mid-March 2026, we replaced our 18-year old HVAC system with a Carrier two-stage HVAC model through McCullough. So far so good. Very impressed again with their rep (Peter) and their customer service. Peter also volunteered to file the city application for getting up a $600 rebate for us, due to the new system's energy efficiency. I also like the fact that McCullough is one of the few HVAC companies in the Austin metro area who is still owned locally, and haven't sold out to out-of-town private equity firms. So, the chance of their customer service suffering is very low, compared to their competitors.
