Vlad installed a surge protector on my AC heat pump after a nasty Austin Electric power over voltage. Great and timely service experience along with very nice customer service!

Thomas Ischy of McCullough Heating & Air Conditioning, was my knight in shining Armor. It was 8:30pm & he resolved my many issues with my A/C unit. Not only did he explain everything in terms, I could understand, he made suggestions to improve the efficiency of my unit. He was friendly, efficient & on time. Thomas is truly appreciated. I highly recommend their services. McCullough hires highly trained, knowledgeable & trust worthy individuals.

Our HVAC was failing to cool and technician Eric Suarez helped us resolve the issue quickly. It ended up being a problem with the thermostat and filter putting the unit in a bad state, which required resetting the unit. Eric was courteous, friendly, and professional.
