HVAC reviews in Denver, Colorado

it was a breath of fresh air working with this hvac company—very trustworthy and no pushy sales tactics. i want to give kudos to the technician, curtis, for representing the company so well. curtis arrived right on time, put on shoe covers before coming inside, and asked me questions to understand my hvac issues. he checked my air filters, used meters on different vents around the house, and also checked the thermostat. curtis inspected the fan and unit above my entry door, looked at the circuit breakers, and examined the compressor unit on the roof. my heater is working well now, but when it's time for a new compressor, i will definitely use this company again.

From the start of the process to the final clean-up, everyone involved was professional and attentive. They installed a mini-split heating system with six indoor units and two outdoor units. Isaac and Frank worked long hours and started early, completing the installation in just three days. On the last day, they even added an unplanned sixth unit. Curtis took my call and quickly arranged for everything to be delivered to the job site. Isaac and Frank stayed late on that Friday evening to make it happen! What impressed me most was their strong work ethic. It was great to see two young individuals collaborating as a team and taking pride in their work, which is something we don’t see often these days. After watching their process and dedication on the first day, it was clear that I made the right choice in having this team handle the project.

I really can't say enough good things about Harmony Heating & Air Conditioning. I hired them years back for a central air replacement job. They not only pointed out an error made by the previous furnace installation company, but they also fixed it free of charge. Fast forward almost a decade, and my furnace blower motor gave up. Without hesitation, Curtis was dispatched on the same day I made the call. Upon arrival, Curtis didn't just rush to the most expensive repair. Instead, he took the time to check other less costly possibilities first. As it turned out, the motor was indeed the problem. The lengths they went to secure a replacement was truly commendable. Curtis also noticed an issue with my A/C unit that I wasn't aware of and resolved it without charging me. This saved me both money and stress. The very next morning, Curtis was back, and within an hour, the replacement was done. This level of service, professionalism, and honesty is what one hopes to find in any company. They are my go-to for all my heater repair needs, be it servicing, installation, or maintenance. Their dedication and customer service is simply outstanding. Thank you, Curtis!

i can't say enough about the great service i got from harmony heating & air conditioning when they installed my new ac condenser and furnace in denver. from the beginning, curtis made sure i understood everything and answered all my questions. the team really knows their stuff and uses the latest ac repair technology. curtis brought in his top crew, and thanks to isaac, carter, and curtis for working so hard and getting everything done right. if you need ac repair or installation, just give them a call for advice or an estimate—you won't need to look anywhere else!

When my air conditioning unit broke down, a dependable AC repair service was my lifeline, ensuring I remained comfortable over the weekend. The next week, they returned and expertly installed a new system. Their quick response, proficiency, and readiness to address all my inquiries genuinely impressed me. Curtis and Blake took the time to thoroughly explain what they had done, offered advice on how to optimize the system's efficiency based on my specific setup, and instructed me on how to use the new advanced thermostat. It's worth mentioning that their pricing was extremely fair. I would undoubtedly recommend this AC repair service to anyone in Denver who requires their services.

I've been a loyal customer for numerous years, relying on their expertise for my two furnace repairs. The team has consistently delivered high-quality results. This summer, it was time to finally replace an ancient furnace. The crew did a brilliant job figuring out the appropriate size for my new furnace and installing it correctly. The team, including Curtis and Santiago, arrived punctually, and completed the work swiftly in Denver. They left no mess behind after finishing their job. Moreover, they took their time to give me a thorough rundown of my new thermostat. I wholeheartedly endorse their furnace repair services and am thrilled with my new furnace!

Santiago has been servicing our heating and AC units for several years, and we are extremely satisfied with the level of customer service and professionalism he provides. He takes the time to thoroughly test our units, cleans everything, and ensures we are prepared for the seasons, giving us peace of mind knowing everything is functioning well. He is proactive in pointing out any potential issues and offers great advice on what to anticipate in the future. We highly recommend Harmony Heating & Air Conditioning for anyone in need of repair services, installation of new units, or routine check-ups on existing systems.

These guys are true heroes. Before I contacted Harmony Heating & Air Conditioning, I had never used their services or any other furnace repair company. I had to reach out to them one evening when my furnace started acting up right before a long holiday weekend. They kept in touch with us all night via phone and social media. When Easton, their technician, got overwhelmed with calls, Frank, the boss, turned around his trip to his holiday cabin to drive back and work on my furnace at midnight. It didn't matter to him that it was a brand they didn't sell or hadn't serviced before. When the old furnace eventually gave up, they quickly arranged a replacement because my partner has health issues and couldn't cope without it. Throughout the whole ordeal, they were helpful and on time, and the new replacement furnace is one of the best and most reliable I've ever seen. Our house is at the perfect temperature all day, every day. I held off on writing a review until we'd had some time to test it out, not just because I was impressed by their customer service. If anyone asks, I would recommend them in a heartbeat. They do remarkable work and will go above and beyond to look after their customers.

Our furnace gave out. Being a fan of comparing prices, I didn't hesitate to get quotes from 2 large retail reps and 2 local furnace repair services. The local folks had no problem beating the prices of the larger competitors (even after one big chain store knocked off $1,500 from the furnace price) and boy, the difference in their approach was noticeable. These furnace repair pros were responsive, trustworthy, and offered top-notch service with a dependable range of products. We decided to go with a unit package - a heat pump for the summer and a natural gas heater for the winter. They truly have a solid grasp of their craft. I can't emphasize enough their dedication and meticulousness. For a minor expense, they even managed to fix our gas oven while installing our new furnace. Without a doubt, they are our go-to for all our heating and cooling needs. Buying local certainly has its benefits!

My husband and I had an issue with our AC in our home. The unit was running, but cool air wasn’t coming through the vents. We called for AC repair and Curtis came out that same day to check things out. Curtis was very professional and took his time to look into the problem. He went under our house to check the ductwork and found that some animals had damaged the air ducts, which explained why the cool air wasn’t reaching inside. Curtis gave us a clear quote, and soon after, the damaged ductwork was replaced with new metal ducts and everything was cleaned up nicely. We are really happy with the AC repair and the friendly service from everyone involved. We definitely recommend their AC repair services in Denver!

Our furnace stopped working right before a cold snap in Denver. I left a message after hours and got a quick call back the next morning. Blake showed up right on time, actually even a bit early, and figured out what was wrong with the furnace. While he was replacing a part, the unit had an issue, so we thought we might have to go a few days without heat. I mentioned I had a space heater but wasn’t sure how to set it up, and Blake kindly helped get it running for us. Really thankful for the great service!

i had a great experience with this ac repair company. they responded quickly and did quality work. unlike other places i called that wanted to charge just for an estimate, this company gave me a free estimate, which i really appreciated. the technician, santiago, was professional and knowledgeable. they not only replaced my air conditioning unit, but also installed a new thermostat. before finishing, santiago made sure to check the temperatures in every room to be sure everything was working right. in less than five hours, my house was already nice and cool. i'm very satisfied with the service and would definitely recommend this company to anyone needing ac repair in colorado.

We had a team come in to install a new furnace and central air system in our home, which had never had central air before. It's working wonderfully to keep our house cool. The installers did an excellent job with both the furnace and the central air unit. We've also had some electrical upgrades done, including installing a circuit breaker box, lights, outlets, and fans. Frank was very professional and knowledgeable, helping us achieve everything we wanted. We're excited to work with them again in the future. It’s been a great experience!

i had a new ac unit installed, along with a furnace, some new ductwork, and an extra return vent added to the addition on my house. right from the start, i noticed their prices were the best around—other places quoted me almost twice as much! the team showed up right on time and worked efficiently the whole day. it was raining outside, but they made sure to keep my floors clean by using shoe covers and laying down moving blankets, which really helped since i have laminate flooring. after finishing the job, they even vacuumed and swept up, which was a nice surprise. the warranties for the new system were sent over the same day, so i have peace of mind. at first, i thought the crew seemed a bit young, but frank and another experienced tech came later to help out and double-check everything, which made me feel confident in the quality of the work. everyone has to learn, and they definitely did a great job. overall, i highly recommend this ac repair and installation service to anyone looking for fair prices and professional results. i’ll definitely call them again for any future hvac work i need!

I needed a quick furnace repair to fix a couple of issues found during a home inspection before selling my house. After finding a coupon online for another company that gave me a really high estimate, I decided to look for a local business. I contacted Harmony Heating & Air Conditioning in Denver and they sent Blake over the next day. Blake fixed my furnace for less than a third of the other company’s price. the work looks high quality and he gave me a detailed write-up of everything done so the relocation company would be satisfied. i’m happy and grateful for such fast and good service at a fair price. for example, the other company wanted $287 for a small repair that only took a few minutes, but with them it was just $10.

After using our new heat pump and furnace system for several months, we can honestly say it works just as promised. Harmony Heating & Air Conditioning really stands behind their HVAC products and services. The heat pump keeps our home cool and comfortable all the time, which is great for the warmer Colorado days. We only open the windows after a rain or when the air quality is good, helping us breathe easier, especially since we use air purifiers too. When we need extra ventilation, like during workouts, we set the furnace fan to high and it circulates the air quickly throughout the house. Most of the time, we run it on the low setting, which gives us just the right amount of airflow without needing any extra fans, not even ceiling fans. The best part is the peace of mind. We’re covered for 12 years—no extra costs or work on our end. We feel confident they’ll honor this agreement, especially since my family has trusted their HVAC services for even longer with great results. Highly recommend them for anyone needing reliable heating and cooling solutions.

Great team to call for heater repair! I had bought my heater from another place, but started having trouble with it not long after. The first company kept coming out, but never really fixed the problem and just tried to sell me extra parts for the heater. I ended up calling someone else, and they said I needed a new heat exchanger and quoted me a really high price for labor, even though the part was still under warranty. I finally called these folks, and I’m so glad I did. Curtis came out, did a full inspection, and also found the leak. He said there was no need to replace the whole coil because the leak was just in the weld of the line. He fixed the weld, recharged the heater, and said it just needed a little more refrigerant but would have to come back since he ran out on the truck. He told me I could just pay when he came back to finish up. This has honestly been the best experience I’ve had with any heater repair service. I wish I had gone with them from the start!

Harmony Heating & Air Conditioning’s customer service really stands out. Our heater stopped working overnight, so we called in the morning and Santiago was at our house within an hour. With how cold it gets around here, I was so relieved that my family didn’t have to go a whole day without heat. The technicians are always friendly, professional, and do a very thorough job. We’ve also used this company for furnace installation and regular maintenance, and every time they are quick to respond and get us scheduled fast. Their prices are fair compared to other places we checked. I highly recommend them for any heater repair or service!

Our experience with the AC repair team in Denver was excellent. The sales rep was thorough, knowledgeable, and very patient with us. We went over the repair options and different service plans several times, and each time the updates and new proposals came back quickly. The installation went smoothly and we’re very satisfied with how everything turned out. The crew, led by Curtis, arrived right on time in the morning, worked hard throughout the day, and finished by late afternoon. They replaced multiple AC units, upgraded our system, and safely removed the old equipment. All of our specific requests were handled as much as possible, and when something couldn’t be done, they explained the reason clearly. Curtis was very attentive, just as our friends had said, and the team cleaned up the work area completely before leaving. We would absolutely recommend their AC repair services to anyone in Denver.

After moving into my new home in Denver, I started having trouble with my air conditioning system almost right away, especially with the summer heat. Within the first few weeks, I had to reach out for HVAC service multiple times because the AC kept shutting down during some really hot days. The first technician replaced the thermostat, which worked for a short while. Soon after, the blower motor failed, and then Curtis from the HVAC team came out to swap in a new blower. That helped for a bit, but then the system started blowing warm air again. Next, Blake arrived and did a very detailed inspection. He discovered that the unit, which was over 25 years old, had never been properly cleaned and really needed to be replaced. At first, my home warranty agreed to replace it, but then they brought in another company for a second opinion. That technician said cleaning might help, but he also hinted the unit would probably need to be replaced soon anyway. Unfortunately, the warranty company then decided they wouldn’t cover anything further. Feeling pretty overwhelmed after the move, I reached out to the HVAC team again. The office staff were very understanding and offered me a great price on a full heating and air conditioning system replacement—basically what they would charge a home warranty company. That made it possible for me to get a brand new, efficient system for my family at an affordable price. But the help didn’t stop there. The team also assisted me in communicating with my warranty provider, and thanks to their support, the warranty ended up covering more than half the cost of the new system and installation. Curtis and Blake came out, installed the new HVAC unit, and took the time to show me how to operate and maintain it going forward. I’m really grateful for the honest, helpful service and would definitely recommend this company to friends and family in Denver looking for reliable HVAC work.

During our home remodel, our thermostat started acting up after it was removed and reinstalled. We reached out for AC repair help during a particularly busy holiday week with rough weather. Even though the team was extremely busy, Easton took the time to talk with us on the phone for quite a while, patiently guiding us step by step through reprogramming our dual fuel thermostat so everything worked as it should. We really appreciate the excellent service, professionalism, and attention we received. We highly recommend this company for any heating or cooling repairs—you’ll be treated with great care no matter how long you’ve been a customer!
