“We recently had our AC and furnace installed by One Hour Heating & Air, and the entire experience was outstanding from start to finish. First, I want to give an honorable mention to Cameron, the initial repair tech. He was professional, honest, and really set the tone for the great service that followed. A huge shoutout also goes to Dakota, Ivan, and Tyler – the installation team. They were all professional, knowledgeable, and just overall amazing. They arrived on time, worked efficiently, and took the time to explain everything in detail. Their attention to detail and commitment to doing the job right gave us complete peace of mind. Not only was the installation flawless, but every interaction we had with this company showed their dedication to top-quality service. It’s rare to find a team that combines skill, professionalism, and genuine kindness the way they do. I highly recommend One Hour Heating & Air – and if you’re fortunate enough to work with Cameron, Dakota, Ivan, and Tyler, you’re in excellent hands!”

“In my opinion, One Hour Heating & Air Conditioning is the best HVAC company in Denver and the northern suburbs. I’ve worked with many through the years. Their employees have to follow a strict code of conduct and quality control. Last weekend I had an air conditioner and furnace installed and Rich W in sales made sure I made the perfect choice by evaluating the space in my condo and going over all of the product and financing options in meticulous detail. Brody S is the hardest working and most conscientious tech I’ve ever worked with. He made sure all of my questions were answered and his job knowledge was exceptional. They exceeded expectations in all areas and true to their name, they are always punctual. Many thanks to them.”

“I had an excellent experience with One Hour Heating & Air Conditioning of Denver thanks to Cameron! He was prompt, professional, and had my AC running perfectly in less than an hour—a huge relief since I am hosting a party tomorrow. He explained the issue clearly, fixed it efficiently, and never tried to upsell unnecessary services. Their prices are fair, and it’s clear they hire skilled professionals who take pride in their work. From scheduling to completion, the process was smooth and stress-free. I highly recommend them!”

“Brody not only fixed my air conditioning system which was totally frozen up, but he also took the time to show me how to use my thermostat properly to schedule my air consumption each day. I’m so grateful for all his help. Couldn’t have asked for a more knowledgeable technician with such a strong ethic over the two days he worked on my system diligently.”

“Cameron was amazing and was super patient and helpful in figuring out the unknown hvac noise. Turns out it was just the pump, phew for me. I’m super appreciative of his help and major bonus points that he already knows this new to me house. Would definitely recommend this company.”
