“My system died Sunday afternoon and I was amazed that I could get somebody out the following morning! Mez did an excellent job identifying the problem and then pushing the supplier to expedite the required part. Definitely will use these guys again and recommend them to anyone looking for AC Repair or Service.”

“Jasmine was very thorough, polite, and professional with the maintenance checks of our furnace. She provided options to restore our furnace closer to its' original efficiency. She conducted a detailed evaluation of our home to determine furnace and our 10 year old air conditioning replacement options. After she completely explained all of the purchasing options she provided a quote with discounts. She answered all of my questions and gave me plenty of time to make a decision. I decided to purchase a new furnace and air conditioning system. Jasmine arranged to have these installed within 2 days!!! This is why I am a long time customer of One Hour Heating & Air Conditioning.”

“The crew thar was sent to my home was polite, professional & efficient. They arrived early & completed the work in a timely manner. We are very satisfied & would definitely recommend One hour to others! Shout out to Ivan for his honesty & professionalism. He completed all the maintenance on our furnace & he did all the work necessary & cleaned everything that was required. in the past, other techs had not done the work they were supposed to yet, ensured us they did. I'm pleased that the company is hiring workers like him & getting rid of the ones who are dishonest!”

“I had a scheduled appointment with Dean of One Hour Heating and AC. He arrived on time and went to work. He discovered the outdoor AC unit had not been wired to my house for electricity. I was fortunate that Dean was allowed to do some installation jobs such as wiring up a unit into the home's electricity. I have a very old house (120 years old) but the AC had been modernized to breakers from fuses. Unfortunately the needed breaker was not a common one. Dean went looking for it in town and found one. He got everything working and gave me a quick tutorial on my touch screen thermostat to top it all off. He was excellent and informative and easy to work with. Definitely a 10 out of 10!”
