“My experience with Grisham One Hour was unexpectedly wonderful. Buying a new hvac system is not really something I wanted to face but they made it very pleasant. Since I was away from home for an extended period, I was not there when the system was installed. My friend who was there for me said the crew was very professional and efficient. I was home when John came to install a soft start for my system to be compatible with my generator. John was very courteous and respectful. He showed me several things about my new system that I didn’t know. I will definitely be recommending Grisham One Hour to everyone I know.”

“Once again, John was very prompt, very polite, very easy to understand, very patient. Excellent service and communication. He took time to explain what he had done when he was here for the repair service, and this time he told me what he was GOING to do, step by step. I appreciated his patience and willingness to explain issues, as well as causes for those issues, as he worked. I’m extremely pleased that he was our technician. I hope that he can always be who comes in answer to our calls.”
