“The technician was on time, his work was efficient, and he even did extra cleaning on a drain. He was polite, quiet, and fast. This company cares about their customers. I made the right decision when choosing them for total furnace and air replacement last fall.”

“I recently had to replace HVAC and furnace. Scotty has been my go to person for many years. Always polite and cheerful. He informed me it was time to get the units replaced. I had been dragging my feet for a while. I took the plunge and had both units replaced. The two guys (Nick was one. Unfortunately I did not get the other person's name.) They arrived about 10:00 AM and never stopped until after 5:00PM. Did not take any breaks, just kept their heads down and worked hard. Very cordial and happy folks. Explained everything they were doing. Thank you.”

In addition to seasoal changeover from heat to AC, he offered expert advice for overcoming a long-time problem of thermostat location simply and based on existing smart Honeywell units.

“I had a great experience with One Hour Heating & Air Conditioning in Torrance thanks to Joshua! He was professional, knowledgeable, and extremely courteous from start to finish. He arrived right on time, quickly diagnosed the issue with our AC unit, and explained everything clearly before beginning the repair. What really stood out was how respectful he was of our home—he wore shoe covers, cleaned up after the job, and made sure everything was running perfectly before leaving. Joshua truly went above and beyond, and I wouldn’t hesitate to recommend him to anyone needing HVAC service. Great service like this is hard to come by!”

Michael repaired and got everything working again. Overall my first experience with them and the tech was exceptional.”

“Zachary Brown, the service technician who came to my home for a a/c tuneup and then discussed the purchase of a new a/c, because my current one was installed in 1996, and is worn out, was very knowledgeable, answered all my questions satisfactory and was very helpful and professional. I received quality customer service which is very rare nowadays. My highest compliments to Niceville one hour heating and air conditioning for employing such a great technician”

Jim was professional and courteous in my home during the install. Would use this company again.”
