Dashon was knowledgeable and even pointed out a possible fire risk from the previous installation attempt. His boss was pleasant, professional and courteous.

“I recently had One Hour Heating install a new heating system in my business, and I couldn't be more pleased with the results! The team was punctual, professional, and incredibly knowledgeable. They took the time to explain the entire process and answered all my questions with patience. The installation was seamless, and they left my space tidy afterward. My business is now warm and cozy, just in time for the colder months. I highly recommend One Hour Heating for anyone in need of heating services!”

“I was so impressed with the service time hour heating provided. The technician was professional and walked me through ghe entire process every step of the way. We had three other companies come out and tell us we need an entire new furnace!! He fixed the problem within an hour and the diagnostic was done within 20 minutes. He troubleshot different things as well . They did so well I signed up for a yearly subscription for the heating and air conditioning check-ups!!Overall I give them a 100/10 !! Thanks again”
