Get matched with top nest installation pros in Greeley, CO

"The quoting and installation process was smooth. There was no pressure to hire them immediately, and they did a good install."

"One Hour has been my HVAC supplier for more than a decade, and I have never had a reason to consider any other firm. This week Justin L. and Steve came to install improvements. They were professional, courteous, and took the time to explain to me just what they were doing, and to answer my questions. On a scale of one to ten they were both elevens. I'd give them six stars if I could. You can trust One Hour to do it right."

"They were very professional and prompt when installing new furnace in the middle of winter. Dean listens to the customer and discusses all options. We called a year later to install AC on furnace and he remembered us and our furnace . Dean is very personable and professional."

"I needed a new furnace so I got 3 bids for replacement. Halo was less expensive than the other 2 by quite a bit. I talked with the owner who was also doing the install. Heâ s a startup company and fully insured, fully certified, and fully licensed. I crossed my fingers and went with them as I prefer local contractors over big box companies. The install was timely and flawless and done on a Saturday! It looks like something youâ d see on a brochure. Zip tied wires, straight piping, and passed inspection by the city in one shot unlike my last furnace. Itâ s a 96% Lennox system with a whole house humidifier. System was installed in one day and ran until midnight the first night and died. I called the emergency number and the owner came out in like 40 minutes and changed a â pressure switchâ (factory issue, full warranty) in 15 minutes and itâ s been running perfectly since. Itâ s quiet, efficient, and I wonâ t be using anyone else in the future for any of my furnace needs. They will get my business again this summer when I get a new air conditioner."

"Tony was fantastic! As a first time homeowner in a new part of the country, itâ s hard to find people you can trust. Tony is someone I happily trust to take care of my furnace. He came in and repaired any issues he saw. He walked me through all the work he did and even showed me how to better maintain things. I have already booked him to inspect our Central Air unit in the spring. I would highly recommend him!"

"He is very professional and did a very thorough job. I highly recommend him."
