HVAC reviews in Denver, Colorado

During one hot summer, our furnace started leaking, so we reached out to a renowned furnace repair service. Their technician, Ryan, assessed the situation and concluded that there was no other solution but to replace the furnace entirely. However, we decided to seek a second opinion and contacted Howard. He informed us that although a temporary fix was possible, we would likely need to replace the unit soon. Remarkably, Howard was able to resolve the issue without charging us. His expertise was evident. True to his word, the fix lasted us through that summer and the following winter. By the next summer, we did need to replace the furnace and, predictably, we chose Howard for the job. His integrity is inspiring, and he delivers top-notch products and services at reasonable prices.

For nearly a decade and a half, I've relied on Harmony HVAC Service for my furnace and air conditioner upkeep. Therefore, it was only natural that when the time came to replace my two-decade-old heater, I stuck with them. I decided to upgrade to a new tankless unit. Harmony HVAC Service team, led by Maxwell, completed the project promptly, ensuring everything was to my satisfaction. They also carry out my annual heater flushing, keeping my unit in optimal condition. I'm just so impressed with their service.

brent and devin came out to fix our furnace in denver. what a fantastic job they did! not only was the repair quick and easy, but these guys have a great sense of humor and a work ethic that's hard to find these days. they weren't just friendly, they were the kind of people you actually want in your home. their workmanship was top-notch too! don’t bother with anyone else—get your furnace repair done by folks who really know customer service and heating systems.

I live in a house with a 40-year-old furnace and AC system. They've been reliable, but I know they're not going to last forever. When my AC stopped working recently, I called in a furnace repair service for a quote on new equipment. I was mentally prepared to spend a significant amount of money on new systems. When they inspected my old AC unit, I honestly wouldn't have understood any of the readings they took, and they could have easily used that to convince me to make a purchase. But instead, Ryan, the technician, was refreshingly honest. He told me straight, 'Your system is still functioning properly.' We found out that it was just a minor airflow issue, and now everything's back to normal. His honesty gave us the opportunity to plan for the inevitable upgrade in a way that fits our budget and timing. They could have easily pressured me into buying new equipment that day, which is a fear many of us have when dealing with service companies. I appreciate the integrity of this furnace repair service and I trust them to be my first choice when the time comes to replace my equipment.

Maxwell and his crew at Harmony HVAC Service are extremely professional. Even though we encountered some challenges with a plumber who mishandled the heat pump on our newly installed HVAC system, Maxwell made two trips to ensure our new HVAC heat pump was properly set up, following the removal of the old unit. He was incredibly swift in restoring our heat, providing guidance to the plumber on the necessary procedures, and even waived the service fee for his two visits - despite the issue originating from the plumber's error. The HVAC heat setup was initially frustrating due to the plumber's mistake, but Maxwell set things right. I will continue to rely on their HVAC services and rate them as excellent following this positive resolution in Denver.

mother’s day turned out great for us! we had family visiting and wanted to keep the house comfortable, so we turned on the ac, but our upstairs hvac unit decided it was time to quit for good. our 5 ton system was completely dead. a friend in the business recommended this company, and i’m really glad they did—they lived up to their reputation for being both quick and affordable. since our old system was over 20 years old, we looked at several replacement options and chose a bosch unit because it offers better efficiency. we figured the extra money would pay off over time with lower energy bills. the only delay in getting it installed was on our side, because of our work schedules. they were ready to come right away, but we had to ask for the next day. once they arrived, they worked fast, got the new ac in, and left everything neat and clean. after work, i noticed the thermostat on a different unit wasn’t working. i called them and they came out quickly, went into the attic, reset a component, and got it running again in no time. the next day, my neighbor thanked me, but i didn’t know why. turns out, when he saw the crew at my house, he asked them to check his own ac. last summer, he was told he needed a new compressor but didn’t want to spend the money, so he suffered through the heat. devin from the team took a quick look, found some loose wires, and got his ac working again—for free! if i had to say one thing, it’s that their name doesn’t capture how honest they are. they aren’t just fast and affordable, but also upfront and trustworthy. they explain your options and help you find something that works for your budget. really happy with our new hvac system and the whole experience.

The team that fixed our HVAC system in Denver really helped us out! We woke up to find our AC wasn’t cooling, even after checking the filter and fuses ourselves. We decided it was best to call in the HVAC pros. They sent someone the same day, and Brent arrived even earlier than expected. He quickly found the problem and had our AC blowing cold air within 20 minutes. Everyone we spoke to was friendly, and I was very impressed by Brent’s skills and fast service. Being pregnant and sensitive to heat, I was so grateful to have the AC working again so quickly. I highly recommend this HVAC service!

We had Brent come out to give us an estimate for heater repair and to install new ductwork to two unfinished rooms in our basement here in Denver. Brent was very knowledgeable, professional, and polite throughout the whole process. Even though it was a busy time with other customers needing urgent heating and AC repairs, he made sure to clearly explain how our three working HVAC units might affect the scheduling of our project. After having dealt with many contractors in the past, it was refreshing to work with someone who didn’t try to overcharge or make unrealistic promises. Brent was honest and explained exactly what he planned to do—and followed through on everything. He never pressured us into unnecessary work and actually helped us save a good amount of money by advising against rerouting some existing ductwork, which we originally thought was needed. The project was finished quickly—less than a month from start to end, which is fast these days. Brent and his team made sure all the work was up to code and met our expectations. We were very happy with the thorough and honest service. I highly recommend this company for heater repair and ductwork in Denver, and we’ll definitely use them again.

here’s my updated review for your hvac services: 1. honesty 5 2. dependability 5 3. courtesy 5 4. workmanship 5 5. value/pricing 10 brent, the hvac technician, was fantastic. i live out of state and needed someone reliable to check out the old furnace in my colorado rental property. brent came by to diagnose the 20-year-old unit and was very straightforward. he recommended a replacement but also gave clear pricing options for a repair. i always like to double-check, so i got a second opinion, and both technicians agreed on the condition and next steps. what really made a difference was that choosing brent saved me about 40% compared to the other quote, and the warranty was just as good. he even sent before and after pictures so i could see exactly what was done, which made me feel comfortable making decisions from far away. i'll definitely reach out to brent again for any future heating or air conditioning needs.

i have had great experiences with Harmony HVAC Service. they installed my furnace system with a hybrid heat pump and gas furnace, and after several years, i still like how it works. a couple small issues have come up, which is probably normal, and howard is always very responsive. brent and devin did most of the installation and were great to work with. another technician came out to service the furnace and was very respectful in my home. overall, it was a great experience.

i had a great experience with my heater repair and natural gas conversion. after i reached out with a general question, howard called me to set up a good time to go over everything needed for the conversion. he explained all the steps clearly, making it easy for me to understand what would happen with my old system and the new setup. as a new homeowner, it was nice to work with someone who really cared about building trust. the office staff and technicians did a great job of scheduling and letting me know when they'd be working. i always knew what was going on. overall, i'm really happy with the quality of the heater repair and the way everyone acted. they are professional, honest, and work hard.

It was a really hot day in Denver when my kids’ furnace stopped working and was just blowing cold air. I called a local company to check it out, and they told me several things were wrong. They quoted me a repair cost of $4,800 and said I’d have to wait 4 to 5 weeks for the parts, or I could pay $12,900 for a new furnace and get it done in a few days. That sounded way too expensive, so I decided to get another opinion. I called another furnace repair company, and they sent Brent out. Brent was polite, respectful, and explained everything he was doing as he worked. The first company had left some parts disconnected and not working, but Brent took his time to fix all of it, even waiting for the system to restart. He found out the real problem was just a bad capacitor. The total cost for the part and labor was about $145. I really appreciate Brent’s honest and professional furnace repair service. He saved me a lot of money!

If you want your heater fixed right, I highly recommend calling these folks. We’ve had them work on heaters in two different homes, and every time, they do a great job. When we moved into our new place, our heater started acting up and our electric bills shot up. Maxwell came out, quickly figured out the problem, and replaced the leaking evaporator coil in just two days. He didn’t push us to buy a whole new heater system and did everything possible to keep our old one working until we’re ready to upgrade. Maxwell also checked the thermostat wiring, found a short, and fixed it so our backup electric heat wasn’t running all the time and causing those high bills. He even looked over our ductwork, sealed up a leak, and adjusted the dampers so the heat flows evenly throughout the house. I really appreciate working with a smaller business that’s honest, knows what they’re doing, and charges fair prices.

harmony hvac service has come out a few times to fix our old ac system that another company put in, and every visit has been a great experience. when the weather got really hot, we decided it was finally time to get a ductless ac unit for our house. from the first estimate to the actual installation, everything was explained clearly and handled professionally. after coming back from a hot weekend away, our home felt cooler and more comfortable than ever. devin and maxwell did an excellent job!

I usually don’t leave reviews, but I had a great experience with my recent AC repair in Denver. After two other companies misdiagnosed my air conditioning problem and told me I needed expensive coil replacements, I reached out for another opinion. Maxwell contacted me before our appointment to get details about my unit. When he arrived, he carefully checked the entire AC system, did thorough diagnostics, and found the real issue—which turned out to be much less expensive to fix. The coils were still in good shape and didn’t need to be replaced at all. Maxwell explained everything he was doing and what he discovered. He really knew his stuff and worked quickly. My AC now works perfectly.

I made it comfortably through the winter at both my business and my home thanks to Brent and his team. They fixed a poorly installed geothermal heating and cooling system, which had been giving me trouble before. After improving its efficiency and reliability, Brent and his crew also replaced an old furnace at my house. Both systems worked great all winter, keeping everything warm and running smoothly. It’s clear they can handle any AC repair or heating job that comes up. Great work!

i recently had heater repair work done by a local, family-owned hvac contractor, and it was honestly the best service experience i’ve ever had. brent and devin were both extremely polite, professional, and made sure to clearly explain all the details of the heater repair before getting started. they were careful with their work, kept everything neat, and finished on time. i first called them for a new heater installation and was so impressed that i asked them back when i needed repairs on another heating system. if you need heater repair or installation, i highly recommend giving them a call—you’ll be glad you did!

I woke up to a freezing cold house and was really worried. I called Harmony HVAC Service, even though it was 4 am, and Howard showed up quickly at my place in Denver to fix my furnace. He was very friendly and repaired my heater in no time. After I paid, I needed to get some paperwork for my home warranty, and Devin helped me right away with all the documents I needed. The customer service was outstanding. I highly recommend them to my family and friends. Fantastic service!

Devin and his coworker came to install my new central AC unit at my home in Denver. They spent the whole day working and did a fantastic job. I can't say enough good things about Harmony HVAC Service. Just today, my AC stopped blowing cold air and I got worried because it was really hot outside. I gave them a call, and they showed up at my house to check things out within an hour. The issue turned out to be a safety feature in the air conditioner—the unit needs a few minutes to reset if it shuts off, and the circuit breaker had tripped because of a quick thunderstorm earlier. The service was excellent. Even though this is a newer company, their professionalism and quality of work are outstanding!

I had a wonderful experience with Harmony HVAC Service. Devin came out and did a detailed and honest inspection of our AC unit. He explained everything clearly and gave us affordable options to replace our central air system. The whole team was professional, polite, and did excellent work from start to finish. They quickly solved our AC problems without any pressure or upselling. You can really tell they take pride in their work and care about their customers. Highly recommend for anyone needing AC repair or replacement!

I had a wonderful experience with their technician, Ryan. We recently had trouble with our heater in Denver when the weather got cold. Another company had tried to repair it, but the heater stopped working again soon after. We decided to call this company instead, and Ryan came out to help us. He quickly found the problem, explained everything in simple terms, and was able to fix it right away. Ryan even took extra time to clean our heater, which the other company never did. The team here was upfront, honest, and gave us a fair price without any games or surprises. From now on, this will be my first choice for heater repairs in Denver.
