“I recently had the pleasure of working with CJ from one hour heating and cooling and can’t say enough good things about the experience. Our HVAC system broke down on one of the coldest days of the year and we’re in a real bind. CJ arrived promptly and quickly diagnose the issue. Not only was the incredibly knowledgeable and efficient, but his friendly demeanor and professionalism made a stressful situation much more manageable. He then went above and beyond to ensure everything was working before leaving and even took the time to explain what had gone wrong and how to prevent it in the future. Thanks to CJ, our home is warm and comfortable again. I highly recommend him to anyone in need of HVAC services he truly saved the day!”

“CJ did a great job cleaning and repairing our heater thermocouple in order to get us back up and running. Looking forward to replacing the old heater soon as CJ has emailed me a quote for a new system.”

“My heater stopped working and I contacted 1 hour heating & air. The technician was Terrell, he was a phenomenal person. Terrell went above and beyond to help fix my heater. I also would like to thank his manager that also went above and beyond to ensure the heater was fixed and my family had a way to be warm. I googled this company by chance but realized God sent this particular person to help me-- with a manager that was just as compassionate about my family having away to heat my home as the weather gets colder. I am humbled and grateful..Have a great holiday season. I would highly recommend this company for any heating & air conditioning problems. Debra”

“Called and they got us in right away for today. Jimmy came out today because we had no heat. He tried trouble shooting, went and got a new part, installed but still not working like it should. Went further into heater and noticed damage. Wasn't safe to use heater. New Heater will need to be installed”
