McCrea is a family owned business that has served our area since 1936. Financing and rebates are available on Trane systems installed by McCrea. Resistrictions apply and these are limited time offers call for details. "Its hard to stop a Trane"

"I had an absolutely terrible experience with McRae Air Conditioning and Heating. I purchased a home equipped with their HVAC system, and within just five months, the heat stopped working—right in the middle of winter during a snowstorm. My home was freezing at 50°F, so I called for service, which should have been covered under warranty. I scheduled an appointment, and the technician, after being several hours late, went to the wrong address, left a sticker on someone else’s door, and left without even trying to contact me. When I called back, the customer service rep was rude, dismissive, and completely unhelpful. He initially told me the technician was on the way and just 12 miles away—but after another hour of waiting, I called again only to be told that the technician had already “been to my house 2 hours ago” (the wrong one) and left a note. If the rep actually wanted to help, he would have told me this during my first call instead of wasting my time and leaving me sitting in the cold. Not once did the technician call me to confirm the address or check in after knocking on the wrong door. When I expressed my frustration, the rep rudely dismissed my concerns, saying, “Well, I had nothing to do with that,” and then interrupted me with, “Do you still want to rebook or not?” as if I had to stop talking or risk not getting another appointment. This was an emergency call in the middle of winter, and McRae handled it in the most unprofessional, careless, and disappointing way possible. If you’re considering using them for HVAC service, do yourself a favor and go with another company. I’ll update this review after the (hopefully successful) service call and speaking to the manager who was not there at 4 pm on a Wednesday."
