“When we called you to come look at our A/C unit, you were quick to respond, eager to dig in and find the problem (despite the hornets nest inside the A/C) and fix the unit, very quickly and efficiently. Thank you. The only thing that would have made me any happier would have been a 50% discount. :-) However, I would sill not hesitate to call you the next time we need help. Well done!”
Advanced Boilers & Hydronic Heating
A/C Repair & HVAC Contractors in Denver
Average rating: 5 out of 5 starsNovember 29, 2019
“I called Advanced Boilers right during the cold snap when everyone was super busy and asked for help because I couldn't get the heating to work in my MIL unit. I had renters who needed to move in and couldn't get the apartment ready for them without heat. Chris rearranged his schedule that day to come out and fix it. He explained what was wrong and what to watch for in the future. I would highly recommend him and will be using him for maintenance on my system.”

“Hands down - Colorado Counter Tops is one of the industries leading companies. From their professional sales staff to their courteous install teams, they're great! They have an excellent range of product and I have found that they are constantly striving to meet if not exceed their customers expectations!”
Hughes Mechanical INC
A/C Repair & HVAC Contractors in Denver
Average rating: 5 out of 5 starsJanuary 14, 2017
“My first experience with Kevin was during Christmas several years ago when I lost a furnace at one of my rentals. Even though it was the holiday he dropped everything and helped me out of the jam. Since then, and most recently in December of 2016 (replaced a furnace in another rental), I have hired Kevin several times, mostly for furnace issues but also some plumbing. He has always been extremely responsive, knowledgable and courteous, up front with all the information (problem and costs) and able to get the job done in a timely fashion. I highly recommend Kevin for your heating/cooling or plumbing issues.”

Quinnair Heating & Air Conditioning
A/C Repair & HVAC Contractors in Denver
Average rating: 5 out of 5 starsJune 27, 2013
“Clean air and comfortable environment for breathing! I live in the mountains of Colorado and have struggled with dry air and dust for 8 yrs. I made contact with Quinnair. The owner of the company came up with his team, while meeting with me for the first time they actually fixed a few issues during the visit. Offered straight forward and knowledgable advice on what was best for me on how to achieve my goals for a more comfortable home. I started out wanting radiant heat and other major items. After carefully explaining to me how to achieve what I needed in a very consultative approach. They saved me considerable amount of money and solved all my issues. I have a whole house humidifier, with a clean effects air filtration system and an air purifier. The cost was was very reasonable for the immaculate and beautiful installation. They would not let me make a single payment until they were 100% sure I was satisfied and pleased with the work. Amazing customer service, I will never use anyone else, always on time flexible and extremely neat and courtesy. Everyone is so very committed to customer service and doing the right thing. They take pride in what they do.”
Heart Heating, Cooling, Plumbing & Electric
A/C Repair & HVAC Contractors in Denver
Average rating: 5 out of 5 starsOctober 11, 2020
“Heart installed a tankless water heater in my house. It works amazingly. They also installed a "comfort valve" that recirculates the water, meaning I have almost immediate hot water in my bathroom. No more waiting forever for hot water. Tremendous service, aware of covid, and took appropriate steps. Worth every penny I spent, and would not hesitate to have them work on any aspect of my heating, plumbing and electrical systems for any reason. AND, it came with a LIFETIME WARRANTY! Who does that???? No-one else that I know... These guys know their stuff better than anyone in Denver, and should be your one and only call”

What do HVAC contractors do? HVAC stands for heating, ventilation and air conditioning. An HVAC technician or contractor specializes in heating systems, air duct cleaning and repairs, insulation and air conditioning for your Denver, CO home and other homes.

When should you hire local HVAC companies?


Generally, Denver HVAC contractors or HVAC installers work with or run companies that repair or install heating systems and a/c services for homes.

Local air conditioning companies can help with a wide variety of air conditioning services, including both a/c installation and a/c repair. Air conditioning contractors, also known as a/c contractors, get extremely busy in the summer when temperatures are highest. For larger jobs, like installation, you might want to hire a/c installers during the off season like spring or fall. You should also try to do the same for heating services. Heating installers and heating contractors might be more available in the summer or fall for larger projects.

Ask HVAC contractors about these residential heating and cooling technologies:


  • Tankless hot-water pumps
  • Residential air cleaning devices
  • Ductless air circulation systems
  • A desiccant enhanced evaporative air conditioner system (for hot and humid climates)
  • Heat recovery systems (which cool the air and heat water with no extra energy use)
