Reliant Heating & Air Conditioning

I received a call back very promptly after posting my request. They were able to accommodate my immediate request, and were at the house the very next morning. The technician called 30-minutes before arriving on-time, and communicated with me and my tenant about the recommended solution.”

Only the Best in Service…Every Time.

They always say, “You get what you pay for.” Here at Reliant Heating & Air, we just don’t think that’s true: while other estimates—high and low—may not offer value in customer service, Reliant Heating & Air promises superior quality in service each and every time.

Family owned and operated, we have made a reputation for ourselves in Colorado as leaders—not just in HVAC, but also in the amount of satisfied customers we have on our books. Is it any wonder? Our technicians have, on average, 30+ years of experience in the HVAC world, not to mention the fact that we offer superior products. Our partners include Bryant, Armstrong Air, Rheem, Peerless, and WaterFurnace, all of whom we have hand-selected as the best in the business. What good is customer service without quality product, anyway? Every one of our partners has made a name for themselves in our business as leaders in quality, reliability, performance, and efficiency. Their products are designed with you in mind, and have prices that stay inside your individual budget. We wouldn’t have it any other way.

Reliant offers services for both residential and commercial clients, ranging from repairs to maintenance to new product installation. We deliver free estimates, reasonable prices, and superior results. Our technicians are NATE Certified (North American Technician Excellence,) as well as EPA Green Team Certified (Environmental Protection Agency.) We know our products and we know that not every solution is for every customer. We will sit with you to determine your needs and offer you the best solutions for your home or business.

Serving the entire Denver Metro area from Boulder to Castle Rock, our normal hours of operation are 7 AM to 7 PM, Monday through Friday. Have an emergency situation when it’s least convenient? We’ve got you covered: we provide 24/7 on-call emergency services, and we always have parts in stock.
