He was polite and identified what had happened for the unit to freeze up and corrected the issue. One hour is my go to for my Heat pump in keeping it in tip top condition. Craig H."

"To say we were happy with Temperature-Control would be an understatement of the nth degree. We hire T-C to install a new, high-end Trane heat pump & air handler in our home. At every step they were professional & responsive. They showed up on time, sent pictures of all employees visiting our property, answered every question we asked and a few we hadn't thought of. The work was done on-time, everything was clean and neat and they checked in at many steps in the process to ensure we were happy and understood what was going on. So far we're 2-3 weeks in with the system and it's operating great. I would recommend this company quite enthusiastically to anyone looking for a new heating/cooling solution in their home."

"Jim responded promptly to my order placed on Angie's List for the Remote Computer Tune Up & Repair Deal. He cleaned up the computer remotely, which was running very slowly, and required frequent re-boots. Computer is running much faster now. Great service. Would highly recommend.
