HVAC reviews in Denver, Colorado

One thing that really stood out about both maxwell and devin was how willing they were to listen and make sure all my concerns were addressed during my heater repair. i had a lot of questions about my furnace and they answered everything clearly and honestly, so i understood exactly what was happening. i also made some requests and suggestions about the heater installation, and they made those changes right away without any hassle. maxwell and devin took extra steps to keep my home clean and took care not to cause any damage. they even painted the exterior vents so they blended in better and helped move some appliances for better access, then put everything back just the way it was. they spent extra time troubleshooting a few unexpected heater issues, and fixed everything perfectly. i asked for a few plumbing changes related to the heating system—some of those were done right away, while a couple are still being scheduled. both techs were very friendly and easy to talk to, both about the job and just in general. they made sure i was happy with everything before finishing up, and that means a lot to me. i don’t often feel impressed by service, but i definitely was this time. i got a reliable new heating system installed and felt treated honestly and fairly the whole way through. i would absolutely recommend maxwell and devin to anyone needing heater repair or installation, especially here in colorado where a good heater matters so much.

Scam/Ripoff Company Be Ware!, Called them to check on my furnace, Technician Steve quoted me $500.00 to replace my thermostat when they cost ~$30 on Amazon. It was determined all I needed was to replace the battery. Also you will get a company called Tipping Hat calling you back not Harmony.

We recently had a great experience with furnace repair in Denver. We've trusted this company for regular furnace maintenance for years, so when our heating system started acting up, we reached out for help. Brent, the technician, arrived promptly the next day to check things out. Even though the furnace was running when he arrived, Brent explained what warning signs to watch for if it stopped again and asked us to call back if the problem returned. Later that same day, the furnace showed an error code, so we called back and shared the details. After further inspection, it was clear that our furnace had corrosion and needed to be replaced. We were very pleased that the new furnace arrived quickly and was installed the very next day. Throughout the process, the technicians were friendly, tidy, and respectful of our home. We highly recommend their furnace repair and installation services in Denver!

I contacted a local HVAC company in Denver to come out and service and inspect two gas fireplaces in my home. Brent, the technician, did an excellent job from start to finish. He gave me a call before arriving to let me know he was on his way, and he arrived right on time. Brent patiently listened to all my questions about the fireplaces and explained each step of the inspection and maintenance process. He discovered a small issue with one of the units and quickly took care of it, making sure everything was running safely and efficiently. Both fireplaces are working much better now and even look cleaner. Brent was very polite and professional, making the whole experience easy and comfortable. I highly recommend this company if you need HVAC or gas fireplace service in Denver.

We were having trouble with our AC unit not cooling properly. I remembered keeping a flyer from a local AC repair company that I had received recently. After checking out some good reviews online, I decided to give them a call. Soon after, their technician, Maxwell, arrived and quickly diagnosed the issue. He went out to get the needed part and returned to fix our AC the same day. Maxwell also talked with me about scheduling a maintenance check for our heating system in a couple of months and gave me information about installing a smart thermostat. I was really happy with the fast and friendly service and will definitely use them again for any future AC repair needs.

I reached out to a few companies in Denver about getting my heater repaired and possibly upgrading to a heat pump system for better efficiency during the cold Colorado winters. Out of everyone I spoke with, this company was the most professional and responsive. Brent was the technician who helped me, and he took the time to explain what would work best for my home. He offered helpful advice and answered all my questions about heater repair and installation. We scheduled a time for the work, which included fixing my current heater, adding a ducted heat pump for our in-law suite, and setting up a separate ductless unit for our main living space. The team showed up right when they said they would, and they were friendly, knowledgeable, and really listened to what we needed. They worked efficiently and made sure everything was running smoothly before they left. Now that we've made it through the winter, our home has been warm and comfortable, and the new system works great. I’m really happy I chose this company for my heater repair and installation, and I would definitely recommend them to anyone in Denver looking for reliable service.

last night, my heater stopped working and was only blowing cold air. today, i reached out to harmony hvac service, and they got back to me quickly. i let them know i’d be home by 4:30, and ryan, the technician, arrived just a few minutes after. he found the problem fast, replaced the broken part, and had everything running again in about 15 minutes. i was really impressed by how efficient and professional the service was. they clearly know what they’re doing when it comes to heater repair. i would definitely recommend them to anyone in denver needing help with their heater.

I saved their number in my phone so I can easily reach out if I need furnace repair again! I called because we were having trouble with our furnace—it stopped blowing warm air. Brent came out to our house that same afternoon. He listened to us, checked over the furnace, and was very professional and helpful. Brent explained exactly what was wrong with the blower motor and said he’d look for the part we needed the next morning so he could get it fixed for us as soon as possible. He found the part quickly, and even though he couldn’t come himself the next day, the technician he sent was just as professional, respectful, and knowledgeable. The repair was done right, and our heat was working again in no time—which is really important in Colorado! I will definitely call them again for any furnace or HVAC problems and would recommend them to anyone. It’s great to have a trustworthy company I can rely on for heating repairs.

this company is top notch. i had to call them several times because my furnace kept having issues during the cold denver winter. every time i called, the person who answered was friendly and even apologized for all the trouble my furnace was giving me. then brent, the furnace repair man, always showed up on time or early, and he was super pleasant and honest about what was going on. he explained everything in simple terms and made sure i understood what needed to be done. i probably had him out to my house seven times for different furnace problems, but he was always patient and helpful. it felt like my furnace was cursed! i really appreciate a trustworthy and caring company with workers who know what they’re doing and care about people in their community. this company has some really good folks. a+++

i was really lucky to find maxwell to help with heater repair and other heating needs. for several years, he has been my trusted expert whenever i had issues with furnaces or needed heating maintenance. maxwell and the crew are hard workers who always make sure the job is done right, and their prices are very reasonable. i first heard about harmony hvac service through word of mouth, and since then i've recommended them to friends and family for their heater repairs and furnace installations. maxwell has helped with replacing old gas furnaces and made sure everything was working smoothly, always showing honesty and pride in his work. most recently, he replaced my older heating unit with a modern heat pump, and even set up a new thermostat to help control both the heat pump and gas furnace together. everything was finished quickly and works perfectly. if you ever need heater repair or furnace service, choosing this team is the best decision you can make.

On one of the coldest days, I realized my heater wasn’t warming up the house. The heat pump didn’t seem to be working at all. I contacted Harmony HVAC Service after hours and left a message. Someone called me back right away, and Brent showed up at my door the next morning. He was very professional and got straight to work. In about 15 minutes, he found out the problem was just a tripped breaker. Brent checked everything else to make sure the heater was running smoothly, so I could stay warm and comfortable. A neighbor had recommended Harmony HVAC Service to me after getting their own heat pump fixed. I would definitely recommend them for heater repair!

Maxwell and Ryan were friendly, professional, and quick with their work. Maxwell showed up ahead of schedule and got everything ready for the AC repair right away. We needed to upgrade our old air conditioning units to a newer, more energy-efficient system, and they got started on removing the old equipment immediately. By the time I came back to check, the space looked completely transformed—everything was installed neatly, with new piping, and they made sure there was no mess left behind. Before leaving, they took the time to explain how the new AC system works, gave me the manuals, and encouraged me to reach out if I had any questions as I adjusted to the new setup. From the initial estimate to the final installation here in Denver, the whole process was smooth and easy.

I run a small business and had two different areas that weren’t being heated properly by my main system. Harmony HVAC Service sent Devin out to install a Mitsubishi split heater, and it was just what my building needed. The price was fair, and the installation looked like it was always meant to be there. Devin arrived right on schedule, worked professionally, and made sure every detail was handled. I highly recommend them if you need any heater repairs or installations. I’m really grateful for how quickly they responded and got my business warm again, so my customers can stay comfortable during the cold Colorado weather. The work was top notch!

I contacted this company to get a quote for replacing our old furnace. Devin responded quickly and gave us a fair estimate without pushing us to buy extra services we didn’t need for our heating system. We decided to go with them for the furnace installation, and within a week, Devin and the team came out and put in the new unit. The whole installation was finished in one day, and they left everything clean and tidy. Devin also explained the furnace repair and installation process to us, which was really helpful. I highly recommend reaching out to them if you need furnace work done.

When our AC stopped working in Denver, I reached out to Harmony HVAC Service. Ryan arrived the same day and quickly figured out what was wrong. Since our old unit was nearly 20 years old and had a serious problem, he explained all our options for a replacement and helped us choose what fit our needs best. We thought we would have to wait until next week for installation, but they called back that evening and said they could come the very next day. Brent and Howard showed up in the morning, installed the new AC unit in just a few hours, and even took the time to walk us through using our new thermostat. The whole team was friendly, knowledgeable, and clearly cared about doing a great job. I’ll definitely be using them for all future AC repairs and maintenance.

my furnace started acting up when it got really cold here in denver. ryan was super quick to respond and showed up right when he said he would, even with the freezing temperatures outside. he came out a few times to get the furnace going, and every visit he made sure the heat was working before he left. we were just keeping it running for a bit, but it was clear the old furnace needed to be replaced when it finally gave out. no blame to the team – it was just time for a new one. just a reminder, make sure to get your furnace checked and serviced regularly! a few days later, i had a brand new furnace installed and i am really happy with how everything turned out. ryan and the team were friendly, professional, and took care of everything with great attention to detail. they even fixed some problems left over from the old installation. their work really impressed me and i wouldn’t go anywhere else for furnace repairs or replacement. i’ll definitely call them again if i need help in the future.

the old furnace in our Denver home started having trouble just before a cold front moved in and we were worried about losing heat. i called Harmony HVAC Service in the morning and they got back to me quickly, just like they said they would. they scheduled a technician, ryan, to come out that same day to check out the system. ryan actually called to let me know he could come earlier, showed up right on time, and explained each step as he checked out the furnace. after talking things over, i chose to replace the old system since it was getting up there in years and repairs would be expensive. the new furnace and AC unit were delivered and installed the very next day, and everything was up and running that evening. i was really impressed with how professional and fast the service was, and now our house is nice and warm again.

I had Harmony HVAC Service come out to install a blower unit for my fireplace. Maxwell and Ryan arrived right on time and got to work, even though the installation turned out to be trickier because my unit is an older model with the same number as newer ones. They carefully removed the log and gas line to fit the blower in, making sure everything was set up perfectly. After the install, they tested the system, made sure it worked just right, and cleaned up the area. The price was fair too. I’ll definitely call them again for future heater repairs and furnace checkups.

if you’re looking for a reliable and experienced team for heater repair, this is the company to call. i got three quotes for a furnace replacement, and this company offered the best value and top-quality equipment, which really mattered to me since i’m on a fixed income. maxwell showed up with the crew and they got started right away. their attention to detail and commitment to doing the job right was clear from the beginning. the installers were friendly, tidy, and clearly knew a lot about heater systems. they finished the whole project in just one day and even fixed some venting problems i didn’t know about, without charging extra. maxwell also made sure i picked the right thermostat and handled all the paperwork for my rebate, which made things so much easier. since i had never needed this kind of repair before, i was a bit nervous, but they made me feel comfortable and showed they are honest and trustworthy. i am very happy with my new heater and the overall service. i highly recommend them if you need heater repair in colorado.

when my furnace stopped working in the middle of winter, my warranty company picked harmony hvac service to handle the repair. i was several months pregnant and my partner was overseas for work, so it was a stressful time. devin from harmony hvac service came out and found out that the furnace needed to be completely replaced. after that, the warranty company would only communicate with my partner, which made things complicated. devin went above and beyond, working directly with the warranty company and keeping my partner updated with emails and calls, to make sure the furnace was replaced as soon as possible. when it was time for the installation, there were a lot of things blocking the path to the furnace. the team tried every way possible to get the new unit in, and they worked really hard to make it happen. i've never seen a company go to such lengths to make sure i was comfortable and taken care of, especially during a colorado winter when it's freezing. they handled all the communication and made sure i didn't have to worry about a thing. after the repair, i noticed my heating bill actually went down with the new furnace, which was a nice bonus. i've since moved, but i plan to call them for any furnace work at my new place too. they really care about their customers and do whatever it takes to help.

I needed a new furnace installed in my home, so I reached out to several companies in Denver for estimates. After comparing my options, I chose Harmony HVAC Service. Ryan, who came by to provide the estimate, was very detailed and always got back to me quickly whenever I had questions about the furnace installation process. The office staff was polite and handled everything smoothly. On installation day, Brent and his team showed up right on time and worked efficiently to complete the furnace setup. The electricians were also professional and made sure everything was done safely. I highly recommend this company for anyone in Denver looking for reliable furnace repair or installation services.
