Reviews of local pros in Denver, Colorado

Marc and the team just finished working on our heater, and I couldn't be happier with their service. I scheduled their $99 heater duct cleaning special, which included any number of ducts, plus a $30 dryer vent cleaning—it really was a good deal. They also gave me a free inspection using a camera to show the inside of my HVAC ducts. My home was built recently in Denver, so I thought everything would be pretty clean, but they found some dust and, more importantly, some brown and green mold in the ducts. Marc explained that this happened because the ducts weren't sealed properly, and moisture and warmth from the attic allowed mold to grow inside. He told me about their process to sanitize the ducts and seal them up to prevent mold from coming back, all for $300. That seemed totally fair for peace of mind and a healthier home. What stood out to me was how they cleaned the ducts from the attic instead of just from the vents—much less mess inside the house that way. Overall, I'm very happy I called them for heater repair and duct service, and I definitely recommend them to anyone in Denver looking for reliable HVAC help.

I usually don’t write reviews, but I wanted to share my great experience with a recent furnace repair and installation. Marc and his team handled the furnace and AC installation, including moving the system to a new spot. The work was very neat and high quality. They worked hard all day, paid close attention to details, and always explained what they were doing before starting any part of the job, including letting me know about city codes. Every time I checked in, they updated me on their progress and checked with me before installing anything on the walls. You could tell they were well-trained and knew exactly what they were doing. Even though they finished late, they still cleaned up the area and made sure to remind me about the warranty before they left. Before choosing this company, I got estimates from several other places, but I picked this one because of their good reviews, fair pricing, and clear proposal. The estimator, Justin, gave honest answers to my questions and explained the pros and cons of each option, which helped me make the right choice. The office staff was also helpful, always letting me know when I’d get updates. The whole team was highly skilled and professional. It’s hard to find good service like this, and I am very happy with the results. The price was competitive, and the quality of work was excellent. I highly recommend them for any furnace repair or installation needs.

These folks really worked wonders! My old AC system had been around for decades and hadn’t worked for years. Thermal Balance HVAC Service showed up on time in Denver, brought a brand new air conditioning unit, got it installed quickly, and even hauled away the old equipment. The crew was friendly, professional, and knew their HVAC systems inside and out. Justin explained everything clearly and answered all my questions. Marc and Braxton did a fantastic job with the installation and kept everything tidy. The whole process was smooth, the price was fair, and I couldn’t be happier with the service. If I could give more than five stars, I would. Their quality of work really stands out!

Marc and Justin installed our new gas furnace and air conditioning unit. They worked efficiently and made sure to clean up the work area once everything was finished. They patiently answered all our questions about how to use and maintain the new HVAC system, including a walkthrough of the thermostat, how to get to the air filter, and tips on where to buy replacement filters. Our old heating and cooling system had finally stopped working, so we were thankful that Thermal Balance HVAC Service could fit us into their schedule and get the new unit installed while the Denver weather was still comfortable. We’ve also called them before for repairs and routine maintenance, and each time we’ve been impressed with how quickly they respond and help us out. Their fast service and reliability mean a lot to us.

We have been happy customers of this local AC repair company in Denver for several years. When we moved into our new home, we found out the heating system wasn’t working right. Marc quickly found out what was wrong and came up with a solution that fixed everything efficiently. Marc really knows his stuff when it comes to both boiler and forced air systems, which was great for us since we have a boiler at home. We also have an older air conditioning unit that needed some extra freon to keep it running through the hot Denver summers, and Marc took care of that too. We had a smooth, trouble-free summer with our AC working perfectly. I highly recommend this business to anyone in Denver looking for honest, reliable AC repair and maintenance at a good price.

On a really hot weekend in Denver, we had an urgent issue with our AC and called for after-hours service. Marc from Thermal Balance HVAC Service arrived right on time, even though it was a busy holiday weekend. He quickly figured out that our upstairs unit was low on refrigerant and traced the problem to a leak in the fan unit up in the attic. Marc took care of everything and made sure our home was cool again. A short time later, our new outside compressor and coils for the air handler arrived. Marc and Braxton showed up promptly and got right to work. They replaced everything, carefully double- and triple-checking their work. In just a few hours, the system was installed and running smoothly. We were especially grateful to have the AC fixed so quickly before our out-of-town family came to visit.

We highly recommend calling this team any time you need help with your air conditioning.

Marc came out to take a look at our AC system. He was clearly experienced with HVAC work and explained everything in a way that made sense.

I've been using this HVAC company for several years now, after my previous technician retired and recommended them. From the start, Marc explained exactly what type of air conditioning system I needed for my home and didn’t try to upsell me on anything unnecessary. I reached out to a couple of other HVAC companies for quotes, but this team was the only one that gave me an honest and accurate estimate based on my actual needs. They might not be the lowest price around, but their honesty and attention to detail make them the best choice. Since the installation, they’ve only needed to come back for regular maintenance, and everything has been running smoothly. After they put in my new AC system, I noticed my utility bills went down by almost $100 each month, which was a great bonus. I highly recommend them for anyone needing reliable HVAC service in Colorado, especially with the hot summers we get here.

Thermal Balance HVAC Service provided excellent service when I needed an air conditioning tune-up for my home. They were able to schedule me quickly, which I really appreciated, especially with the warm Colorado weather. Marc arrived on time, was very friendly, and worked hard to make sure everything was running smoothly. He discovered that one of the ducts had come loose from the main unit, which was why our house wasn’t staying as cool as it should. After reattaching the ductwork and fine-tuning the system, the air conditioning worked perfectly and the whole house felt much more comfortable. The price for the ductwork repair was a bit higher than I expected, but the quality and thoroughness of the service made it worth it. Overall, I’m very happy with how everything turned out!

We had a recurring issue that others couldn’t fix, but the HVAC technician identified the root cause and resolved it properly.

After years of neglect, my HVAC system feels brand new! The team was incredibly thorough, and I noticed a difference in air quality within an hour.

Phone interaction was awful. I had all the info needed to get a simple round about figure that I was able to get from 5 other companies and they refused requesting a guy come out.
