“Brayton came out to assess our heating issue. He was able to answer any questions I had. He was professional and very informative. Chad came out to get measurements and estimates on replacement costs for both furnace and AC. He came up with a price of $16,200, which we thought was very reasonable. He was able to walk us through the financing and got us a payment that worked for us. Then Jason and Raul came out for the replacement of our old system. All in all great work from all. We are very appreciative as the temps have been below 20. I called on Sunday afternoon and had a technician at our door at 8 am Monday morning. Thanks again to everyone involved in helping us solve the issue. I will recommend One Hour heating and cooling to anyone who needs their services.”

“This is an excellent company to work with. Their technicians are all very capable and personable. They were meticulous and did not rush but were efficient and made sure they took time to explain anything we needed to know. They worked long hours so we were not inconvenienced and they kept us informed about arrival times. We have used them for other installations and routine services for years. Also, their pricing is very fair and less than other estimates.”

“Our heating went out right before the coldest week of the year, and we called late at night and One Hour was out the next morning for evaluation and repair. While it was unfortunate our system ended up being over 20 years old and needed replacement, the representative from One Hour explained multiple options and was never pushy to what decision we should make. He was very informative, answered all of our questions with zero pressure and was very friendly. The very next day other individuals arrived right at the time that was estimated to complete the new install. The people that came worked efficiently, quietly, and did a thorough installation. Our new system looks great, and the team stayed to talk us through all the features we needed to know. Overall, I’m very impressed with this company and service. Needing to get this type of equipment replaced is not fun, but they made it as painless as possible. Thank you!”

“Technicians were great! They were professional. knowledgeable, and timely. It was an extremely cold day with 12 inches of snow that had just fallen and to be out in our garage for the install wasn’t ideal but they got us back up and running in just a few hours. The new system is working so great and we can already tell a difference in how much more efficient it is running than our old one.”

“So grateful for the quick, fantastic, and friendly service from Oscar this morning during sub zero temps. Woke up to the furnace off and house at 52 degrees, and by 10am, he had arrived, diagnosed, and fixed the problem, and I had warm air blowing through my vents again. Signed up for their maintenance program on the spot because I was so impressed by their service, and will happily use them again in the future”
