Great honest company.

I called at 3:30 pm to have our heating unit serviced. He was at our home in 30 minutes. Ten minutes he was able to tell me the problem and the cost. He went for parts and returned to repair. The entire service was handled in two hours. I have small children and we needed to have heat. The cost is very minimal. I am completely satisfied.

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!!!

I was dreading a huge bill but when the service man came by it was a simple fix. Thanks for the honesty.
