"I currently have a service maintenance agreement with Chenal Heating and Air for service on both my residential and office units. I am very pleased with the service and technical expertise of their technicians. Their response time has been excellent. We also purchased a replacement unit at our home from them and I have been extremely pleased with that installation. I found their sales people to be technically sound and knowledgeable, a notch above most that I have dealt with. I’d recommend you give them call if you are in the market for their services."
