"Very Professional and did not hesitate to explain everything in detail. It is hard to find an HVAC company you can trust to show up and do it right the first time and I believe this is one. Will recommend for future jobs!"

"I had a great experience from start to finish with this company. They were able to install my new AC unit quickly, which I was thankful for, considering how hot it has been. Throughout the entire process, they were transparent with their pricing, explained everything clearly, and never made me feel pressured. Dylan and Tristan were incredibly knowledgeable, professional, respectful, and kind. They took the time to answer all of my questions and made sure I understood what was being installed and why. I was honestly pretty stressed about having to replace my AC unit, but they made the entire experience easy and worry-free. I would absolutely recommend this company to anyone looking for honest, reliable HVAC service. Their customer service and quality of work exceeded my expectations, and I couldn't be happier with the experience."

"Our furnace wasn't working one evening and they came out after hours to help troubleshoot the problem. He gave us the option to pay a warehouse opening fee and have it fixed that night or do it first thing when they opened in the morning. He also identified some other issues with our furnace that was hurting efficiency that he fixed while he was there. Great service and will definitely call them again with any HVAC problems I have."

"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."
