HVAC reviews in Denver, Colorado

We had a great experience with our AC repair in Denver! Our new unit was installed by the team a while back, and their price was the best we found. They even fixed our ductwork to make it more efficient, which other companies didn't include in their quotes. Recently, our AC stopped working because of a small part, but Nicolas came out the next day, replaced the part, and took care of the warranty paperwork for us. We only had to pay a small labor charge. Every technician we've met, including Maddox and Tony, has been professional and polite. When they had to come back again, they arrived right on time. The technician was friendly and the cost was very fair. He replaced an outside line, emptied an overfilled pan upstairs, and added a little Freon since it was low. We highly recommend their AC repair services and will keep using them!

i called champion hvac service because my heating system stopped working in the middle of winter. maddox arrived within an hour and quickly diagnosed the issue—it turned out to be a simple and affordable thermostat repair. later, i decided to have a gas heater installed in my garage and needed a gas line run to my fireplace. maddox explained the most efficient and cost-effective way to handle the installation. the team was always on time, friendly, organized, and clearly experienced with hvac systems. they made sure everything was set up correctly for colorado's cold winters. it's a relief to have reliable professionals to count on for heating and cooling needs. highly recommend!

This is the only company I trust for AC repair and keeping my cooling system running smoothly. They’ve handled jobs that others couldn’t fix, and their prices are always fair. I’ll keep using them for any AC services I need. I really appreciate all the help they’ve given me so far. Just recently, I had my AC unit and furnace cleaned in Denver. As usual, the technician—Tony—did a fantastic job and took the time to answer all my questions.

service really matters. these guys are true hvac pros and make sure everything is done right the first time. i decided to go with their service contract for my furnace, and having priority on repairs has definitely been worth it, especially during those cold colorado winters. both the furnace technician and the plumber, jayden and tony, were fantastic—very skilled and friendly. the only small thing i noticed was that their air filters cost more than what i've seen elsewhere, but honestly, the quality of their work more than makes up for it. i highly recommend them for anyone needing hvac help. you could try fixing things yourself, but it's so much better to have it handled by experts.

The team was great to work with! They arrived quickly to check out our AC and figured out that the compressor was no longer working. Our AC, furnace, and water heater were all really old. They put together a clear and professional estimate to replace all three units, plus a few extra parts. We thought the price was fair for the equipment, service, and support they gave us. They did an excellent job from start to finish, even helping us with some extra financing options. We highly recommend them for any AC repair or HVAC service needs.

Having our furnace break down during the winter at my rental property in Denver was stressful, but Champion HVAC Service made the experience much better. After getting a really high quote from another company for repairing my old unit, I reached out to them. Nicolas came out quickly, gave us a temporary fix so my tenants had heat right away, and then replaced the old heater within just a few days. The new installation was smooth and the equipment works great. I’m glad I didn’t waste money fixing something that needed replacing soon anyway. I definitely recommend them—they truly care about their customers.

I have been using Champion HVAC Service for over 30 years for all my AC and furnace needs. I purchased my AC and furnace units from them, and their service and warranty support have always been excellent. As part of their yearly maintenance plan, a technician arrived right on time, called about 15 minutes before coming over, and was very polite and professional. He wore a mask for safety. The technicians here are true professionals and many have worked with the company for years. The technician who serviced my system today was actually one of the same people who originally installed the unit. Now, it was time for the fall furnace check. Once again, the technician was very thorough and professional. He pointed out a few areas that could become problems later on but assured me that everything is still safe. He just wanted me to be aware for the future—there was no pressure to replace anything now. The technicians are always friendly and experienced, never trying to push unnecessary sales, and their prices have been competitive when I’ve bought new units. Whenever I’ve supplied my own filters, the techs installed them for me at no extra cost. They have always fully honored any warranties, and once even found a warranty I thought had expired, which saved me a lot of money. If you need someone for AC repair or related services, I definitely recommend giving them a try. They are more than worth considering.

I recently visited an old farmhouse being restored in Denver and discovered that the thermostat wasn’t working, which meant the AC and heat wouldn’t turn on. With cooler weather coming soon, I knew I needed a quick fix, so I looked up local AC repair services and asked a friend for advice. I called and was really impressed with how fast they responded—Nicolas arrived just a few hours later. He quickly figured out the problem, replaced the thermostat, and made sure the whole heating and cooling system was working perfectly. Nicolas also took the time to show me how to use the new controls and made sure everything was clean before he left. He was very polite and professional throughout the whole process. Overall, I had a great experience with this AC repair service in Denver and highly recommend them to anyone needing help with their heating or cooling system.

i was having trouble with my ac after moving the thermostat, and couldn't get the system to turn on. i called and was quickly connected with jayden, who helped me out over facetime. jayden walked me step by step through what to do, and we were able to fix the issue without anyone having to come all the way to my house in denver. he was super professional, friendly, and explained everything clearly. i really appreciate this kind of great customer service—it's not something you see every day. this company really puts customers first and it shows. i'll definitely recommend them to friends and family looking for ac repair in denver.

I had a fantastic experience with Champion HVAC Service when my AC stopped working. Their technician, Gavin, arrived quickly and was very thorough in checking out the problem. He explained the issue clearly, walked me through all the possible repair options, and took the time to answer every question I had. The whole process felt honest and straightforward, and I really appreciated the friendly attitude and attention to detail. Gavin also helped me set up a plan for future maintenance and scheduled follow-up visits to make sure everything would keep running smoothly. I’ll definitely call them first if I have any AC problems again.

Champion HVAC Service recently repaired my old furnace, boosting both its heating power and energy efficiency. Maddox handled the repair and did an excellent job—the furnace looks and runs great, and you can tell he really cares about doing quality work. This isn’t my first time calling for help. Previously, they put in a new hot water boiler and water heater at my house, and later came back to upgrade my outdoor faucets to frost-free models. Every visit has been a positive experience, and I’ve always been very happy with the outcome. I’ll definitely keep calling them for any furnace or heating system needs in the future.

From start to finish, the team did an outstanding job with our furnace repair and heating project. We recently added a new space upstairs and needed to make sure our furnace could keep up with the Colorado cold. We had several companies come out for quotes, but most tried to push extra services we didn’t need. When Gavin came to take a look, he really listened to our needs and carefully checked if our existing furnace setup could handle the extra space. He took the time to figure out the most efficient way to set up the supply and return vents so every room would stay warm without wasting money. During installation, Gavin even found a small leak in our furnace and took care of it right away at no extra charge. He was upfront, honest, and genuinely cared about doing the job right. Now everything works perfectly, just like he promised, and the cost was much less than what others quoted us. I highly recommend calling this team for any furnace repair or heating work—you won’t be disappointed!

Gavin was professional, careful, and very knowledgeable when he came out for an emergency HVAC service on a Sunday afternoon. He arrived right on time, quickly found the real problem—which turned out to be a simple wiring issue with the boiler, not the thermostat as I originally thought—and fixed it right away. Gavin also offered to install a new thermostat, which I decided to go ahead with, and he took care of it on the spot for a fair price. I was very impressed with the service and will definitely be calling them again for any future heating or cooling needs. Highly recommend!

we called for furnace repair when our heater stopped working, even though the fan was still running. nicolas came out and quickly figured out that the problem was a failed contactor. he was very knowledgeable, honest, and friendly the whole time. i really appreciated that he didn't try to push us into replacing our entire furnace, which other companies have tried before. the repair cost was fair and reasonable. nicolas also installed a new wi-fi thermostat for us, and the pricing for that was great too. we’re keeping their card handy on the fridge for any future furnace issues, especially with how cold winters can get here in colorado.

We had a technician come out to our home in Denver to inspect our fairly new furnace and offer advice on relocating a cold air return after we removed some walls. Jayden, the service professional, not only made some helpful adjustments to our HVAC system, but also came up with a smart and budget-friendly way to move the cold air return—something other contractors hadn’t suggested. The old return was sealed off and a new one was installed for a very fair price, and our furnace was also serviced during the visit. I’m really impressed with the quality of service and would definitely recommend this company to anyone needing HVAC work.

We’ve lived in our Denver home for several years and have always had trouble with our original gas furnace. Over time, we had lots of different companies come out to try and fix it, but none of them seemed professional or memorable. This was the first time a company actually took the time to help us get the furnace replaced for good. Our family, including our two young kids, had to go without heat for over a week, and our home warranty company wasn’t making things any easier. Tony and his team were amazing—they kept checking in with our warranty company and made sure we got a brand new heater installed before the cold weather hit Denver. Their customer service was top-notch. Both Tony and Jayden made sure to keep their promises and really helped us out, which is rare to find in this industry. From now on, this is the only team we’ll trust to take care of our gas furnace and heating system. They are knowledgeable, professional, and always go the extra mile. I definitely recommend them if you need heater repair or replacement!

We recently had Maddox and his team from Champion HVAC Service replace our upstairs heater system. This was actually the second time we called them—they installed our downstairs furnace before, and both jobs were done really well. they are very knowledgeable about heater repair, always show up on time, work efficiently, and their prices are fair. we are very happy with the service we have gotten and plan to keep using them for regular heater maintenance. we have them come out to our home in Denver twice a year for spring and fall heater checks as part of our maintenance plan. they never try to sell us anything we don't need, and their service is always top-notch. if you're thinking about switching from another company, definitely get a quote from them. you won't be disappointed. tony came out recently for our spring heater maintenance and was very friendly and thorough. we continue to be impressed with their work and highly recommend them if you need heater repair or regular service for your heating system.

I recently had my furnace repaired, and I was really impressed with the service I received. Two technicians, Jayden and Maddox, came out to take a look at my furnace, and right from the start, they made me feel comfortable by greeting me with a handshake. Jayden seemed very experienced, while Maddox was newer to the team but clearly knew a lot about furnace repair. Both of them were very knowledgeable and answered all of my questions about the work that needed to be done. They took the time to explain the repairs in simple terms while sitting with me in my living room, so I felt like I was part of the process and understood everything. I appreciated that they didn’t try to sell me anything I didn’t need and focused only on what was necessary for my furnace to run properly, especially with Colorado’s cold winters. Their customer service was excellent from start to finish. When they finished the job, they shook my hand again and made sure I was satisfied with the work. I really felt like they treated me like family and genuinely wanted to help. I would definitely recommend this company and these technicians to anyone who needs furnace repair.

Jayden was truly outstanding when it came to handling our old furnace during a cold snap in Denver. Our furnace broke down on a Saturday, and Jayden came out right away to check things out and work on our old Lennox unit. He quickly ordered the part we needed and got our heat running again for a few days while waiting for the replacement. Even late at night, Jayden showed real dedication by coming over to make sure everything was safe for our family. He let us know honestly that our heat exchanger had cracked, and for safety reasons, we needed a new furnace. The very next day, Jayden returned and installed our new furnace in just a couple of hours. He worked quickly, cleaned up completely, and it was as if he’d never been there. I’ve never seen such commitment from an AC repair technician—he really does show up any time, day or night. We had called another company in Denver before, but they wouldn’t even work on our Lennox system. It seems lots of homes here use Lennox, so it was great to have someone with real experience. Now, with our new Rheem furnace, the house heats up fast and it runs so quietly. Jayden told us more than once that customer service is his top priority, and it truly shows in his work. Highly recommend for any AC or furnace repair needs!

It was a great experience having Champion HVAC Service install our new furnace system. We had several HVAC companies come out to give us quotes, but we chose this company because they were quick to respond and made us feel comfortable from the start. Maddox visited our home twice and spent plenty of time going over all the furnace options that would work best for our space. We had a small area to work with and changed our minds a couple of times, but Maddox was always patient and helpful. Once we made our final decision, a two-person crew came out the next week to handle the installation. The installers were friendly, answered all my HVAC-related questions, and were flexible with my requests during each step of the process. During the install, I asked if they could build a custom duct piece instead of using a standard one, and they did it right away without any extra charges. A week after the furnace was installed, we noticed a slight noise and had a few more questions. Nicolas came out, explained that the sound was caused by the type of filter we were using, and showed us how to reduce it. He also double-checked the furnace, adjusted the gas pressure for better performance, and helped us set up our thermostat to work better with our new two-stage heating system. All HVAC companies can offer similar equipment, but it’s really the people that make a difference. Our whole experience was fantastic, and we feel confident recommending this service to others looking for reliable heating solutions.

The team efficiently restored our ventilated ceiling, finishing an hour earlier than expected while ensuring everything was spotless. Highly recommended!
