Extremely professional and knowledgeable. Kevin and Aaron(service technicians) went out of their way to schedule a visit that was convenient to me. They were prompt, courteous, and generally excellent to deal with. They were able to diagnose a problem with an AC unit that other companies had spent months fooling around with with no real results. 5⁄5 John Davis Heating and Air will be the absolute first on my list for any future problems, and will be the company I recommend to anyone who asks.
