Just had my Spring inspection with Lynell Greene of McCullough Heating and Air Conditioning. Although I had to replace a overflow safety switch, the seasonal inspection was great as usual. This HVAC system is primo. I love it! Lynell was efficient and very knowledgeable, answering any questions and providing information in a pleasant yet professional manner. At no time did I feel he was 'mansplaining'. McCullough has such nice Techs. Great staff, excellent products. Yes, I would definitely recommend McCullough. They are the best IMO.

Mike came over today and saved the day for our family, the units wasn’t working and Mike quickly identified the problem with my system, there was a rodent that had eaten the wires which he quickly redid the wiring then cleaned the coils and checked everything out. He also told me about it being a family owned and operated company and last one in austin I’m so glad and grateful mike and mcculough
