"One Hour Heating & Air has been servicing my HVAC system since I moved to Fort Collins four years ago. Greg Nieves is excellent. He took time to answer all questions and went out of his way to offer suggestions and make sure I understood everything.. This company is totally competent although their prices seem a bit high. However, their service is great and worth the price since I've never had to call them back with a complaint."

"Absolute 1st Choice will absolutely be our 1st choice. He deserves more than 5 Stars. He found problems that were more serious than the one we hired him to fix. He explained what needed to be done and offered to do it. He made no attempt to "upsell' us on anything. He stayed until the project was completed to our satisfaction. He was well organized, professional and trustworthy. Trustworthiness is the most important thing, without that I might as well have tried to fix it myself. I know that wouldn't have ended well. If you hire a company with a fleet of fancy trucks and prime time TV ads, you can be fairly sure that the service tech will , at some point, magically transform into a a salesman. Thank you, Home Advisor!!!"

"Tony was very easy to work with and accommodating. I had narrowed my choice to 3 firms. Elevation was not the cheapest nor the most expensive but I felt most comfortable with Tony and believe he offered the most value. My air conditioner was installed today, I hope this will be the start of a great (and cool) relationship."

"Adrian was tremendous! He took on a tough project, never gave up and solved my HVAC problem. Patient, thoughtful, collaborative with pricing. Recommend him without reservation."

"They did an exceptional job and provided valuable (and fair) insight on the level of cleaning / inspection needed for various chimneys throughout our home. Would definitely recommend."

"I hired Comfair for my hvac last weekend and I couldn't be happier with the results. Habib was professional, punctual, and knowledgeable. He quickly diagnosed and fixed the issue with my system and his pricing is really reasonable. Highly recommend Comfair with all hvac services."

"A-Moonlight provided timely and professional service. They were able to diagnose issues with my A/C and furnace quickly and explained the issue and their proposed solutions. Brent made me aware of my options for repair and what services were necessary and what was not. They were able to install the parts I purchased and service my furnace and A/C within a few hours. They got everything working in one trip and charged about 1/6th of what a competitor was asking. I would highly recommend A-Moonlight for any residential HVAC needs and I will be hiring them in the future should I need any other HVAC services."

"Jason was great! My expansion tank on my water heater blew over night. Jason was quick to respond, charged fairly, and had the new water heater installed same day. Extremely professional and friendly. Highly recommend his services and I will be using him again."

"We had two AC units and a new furnace installed they were prompt, efficient, very respectful and great customer service! Dean was an absolute pleasure to work with, they have earned my business for life on any HvAC services I might need! Highly recommend"

"Mario was awesome! He explained the problem clearly and the needed repair. He showed me the part he was installing and the one he took out. He also let me know what things I could do to lengthen the life of my furnace. There was no upsale and no pressure to get a new furnace at a time when that isn't possible. This company provides honest, quality work at a fair price. We will use them for all our future HVAC needs!"
