Very professionally, Keith inspected my old unit and gave me a very reasonable quote on the spot. Originally, my wife and I were going to shop around for the best price but I decided to give them our business because of the price (including parts, labor, military discount, everything else) and timeliness. Keith offered to come out the very next day. His employees arrived first thing in the morning and worked through a heavy downpour. They were very courteous and mindful not to track mud in the house and offered to clean the floors as they worked. The guys even offered to seal a leaking radon vent on my roof that i just found (That had absolutely nothing to do with my air conditioning) for free. They all were very professional and did a phenomenal job for an unbeatable price. I will HIGHLY recommend their services to anyone I know!!!
