Relieved and thankful!!!!
Thanks to John Markl for getting his son Randy to my house in 10 minutes and getting my air fixed today. I was near tears this morning when my home warranty sent a company from Dallas area and said I needed a new unit for $4000 and my warranty company (Choice Warranty) wanted to pay only $350 of it. Thanks John and Randy, you’re the best!!!

Friendly and fast same day service. The two guys that came out were very knowledgeable and had our old AC unit up and running within an hour after replacing a part.
