HVAC reviews in Denver, Colorado

I needed some heater repair work done and wanted my furnace vents moved to a different spot on my roof. I called several places, but none could come out before my roof work was finished. One company referred me to another team, and they were able to get the job done quickly. Walter and his crew came out, moved the furnace flues, and even installed a few vent terminations for me. Everything looks great, the price was fair, and they were really friendly and easy to work with. I’ll definitely be calling them for any future HVAC needs.

Harmony Heating & Air Conditioning has really impressed me with their heater repair service. Curtis and his team were outstanding right from the start with my home’s central heating system. Curtis came over, checked out my heater, and clearly explained my options—from replacing just a few parts to installing an entirely new system. It was really helpful to get choices, especially since this was a big investment. Curtis spent plenty of time answering my questions, and just a couple of days later, I had a detailed quote. He helped me decide on the best new central heating and air conditioning system for my home. After I made my choice, Curtis let me know it could take about two weeks for the new equipment to arrive, but he actually called after just one week to say everything was ready and wanted to set up the installation when it worked for me. On installation day, Curtis and his team arrived right on time. They took out my old furnace from the attic and the condenser coil, then put in a new 4-ton condenser outside and the new furnace in the attic. Everything was installed, tested, and working smoothly in just seven hours! I really appreciated how careful and tidy they were—they put down protective cloths at my entrances and were careful with my yard during the outdoor work. I highly recommend Harmony Heating & Air Conditioning for any heater repair or central heating needs. I would definitely use them again in the future!

Carter and his team were very professional during the whole heater repair and installation job. The consultation was clear, and Carter explained all the different options for fixing or replacing my old heating system. They had to remove the entire old furnace and all the ductwork before putting in a brand new heater and new ducts. Every step of the way, they made sure to answer my questions and told me exactly what they were doing and why. I noticed the difference right away after the new system was running. My heating bills have gone down a lot, and now I don’t need to worry about how I set my thermostat. I’m really happy I chose Harmony Heating & Air Conditioning for this job.

i've used this company's hvac services in denver for both heating and cooling needs, and i'm really happy with how professional they are. easton always arrives right on time, keeps the workspace neat, and solves any issues quickly. i had a problem when my furnace started making noise and stopped blowing warm air. after i called easton, he figured out what was wrong fast, picked up the needed hvac parts, and had everything repaired that same day. he even did some extra maintenance to make sure my system was running perfectly. the cost was very fair, and i'll definitely keep coming back. five stars, highly recommend for anyone needing reliable hvac help!

The technicians quickly found the issue with our natural gas heater during their visit, and the initial $159 diagnostic fee was applied to the final cost of $908 for replacing a faulty gas valve. The needed part was ordered and arrived within a couple of days. The team kept us updated by texting when they were on their way, and also gave us a number to call if we had any questions. Frank, who handled the repair, was friendly and worked efficiently. He replaced the gas valve, tested the system, and showed us that the heater flame was working correctly again. We were originally referred to this company by another heating professional who couldn't do the repair on our mobile home heater, but who also didn't charge us for his diagnosis. We had considered another company, but chose this team because they could come out much sooner. Overall, we had a great experience and are happy our heater is back up and running, especially with the cold Denver weather.

our furnace was getting really old and started having problems, so we called for a quote on a new system. after a while, we needed a quick fix for the old furnace, and walter came out to put in a temporary part. he found a big carbon monoxide leak, which could have been dangerous. the team worked fast to help us get approved for financing and scheduled the full furnace replacement right away. since we couldn’t use the furnace, walter even brought over two space heaters so we could stay warm through the cold colorado night. the next day, isaac and carter arrived early and got everything installed smoothly. everyone was friendly, professional, and really cared about making sure our home was safe and comfortable. we’re so glad we chose this company for our furnace repair and replacement. we’ll be customers for life!

I had an issue with my furnace and talked to a few other companies before finding Harmony Heating & Air Conditioning. The other places suggested I should replace my whole furnace, even though they offered to change just one part, and didn’t seem too sure about fixing it that way. I felt uneasy about replacing the entire unit. I’m really glad I called Harmony Heating & Air Conditioning instead. Carter was knowledgeable, professional, and showed up right on time. He explained everything to me in simple terms and answered all my questions. He repaired the broken part of my furnace at a fair price, and now it’s working perfectly again. I would definitely recommend them for anyone needing furnace repair.

i’m really pleased with the hvac service i’ve received. we signed up for a maintenance plan that covers two system checkups each year—one in the fall for our furnace and one in the spring for our air conditioning. after comparing different options, i found their pricing to be the best value for regular maintenance. every person i’ve spoken with from the company has been friendly, and the tech who came to our home, easton, was both knowledgeable and polite. he explained everything clearly and made sure our heating and cooling systems were running smoothly, which is especially important here in colorado with the changing seasons. i plan to request easton for future visits if possible. overall, the whole experience has been easy and i feel confident that our hvac systems are being taken care of by professionals.

Walter and Frank came out to my barn in Denver and repaired my mini split HVAC unit after I’d had a hard time finding someone who could help. They got the system running smoothly again in less than a day, and I was impressed by how knowledgeable and professional they were. Both were courteous and friendly, and the price stayed exactly as quoted—no surprises. I really appreciated their honest work and fast service. I’ll definitely reach out to them again when I need HVAC work done in my main house. Highly recommended!

I highly recommend Harmony Heating & Air Conditioning for heater repair services. When our furnace broke down during the winter, they responded quickly and sent Curtis out that same day. He got the heater running again and let us know it would probably need to be replaced soon. Curtis didn't charge us for that first visit, which really showed they cared about helping us. When it came time to replace the furnace, we chose them, and the whole process was fast and the price was fair. More recently, after a power outage caused another issue with our heating system, Curtis came out right away, figured out the problem, and fixed it quickly. Their reliable and friendly service gives us peace of mind, especially with Colorado's freezing winters.

Blake was fantastic. He had serviced my furnace before, and I was very pleased with how everything turned out. I also had them install a new water heater recently, and I’m just as satisfied with that job. Isaac handled the water heater installation and did an outstanding job. When I noticed an issue with my A/C unit, I called for an appointment thinking it might need to be replaced. They came out to my home in Denver the very same day and quickly fixed the problem. Instead of recommending a costly replacement, they repaired it right away. I really appreciate how reliable and trustworthy this HVAC team is—it’s great knowing dependable service is just a call away.

When our AC technician, Santiago, arrived at our home in Denver, he quickly started diagnosing the issue with our second air conditioning unit, which wasn’t cooling properly. Even though it was late in the day and he had been working hard all day, Santiago took his time and worked through every step to find out what was wrong. He narrowed it down to a couple of possible causes. Santiago then went out to his service truck and returned with a part he thought would solve the problem—a Honeywell ignition control module. Once he installed the new module, our air conditioner was up and running smoothly again. We truly appreciate Santiago’s skill and dedication. We’ve been customers for a long time and always feel confident recommending this AC repair company to friends and neighbors in Denver. Not long ago, we scheduled our annual AC system checkup and cleaning for both of our units. We specifically asked for Santiago again because of our great experience before. He arrived right on time and during the inspection, he found an issue with our older unit. Santiago explained that while it wasn’t urgent, it would be smart to fix it before it turned into a bigger problem. After we received an estimate from the office, we decided to go ahead with the repair and, of course, asked for Santiago to handle it. He showed up early and replaced the needed parts, making sure everything was running just right. This AC company in Denver is reliable and trustworthy, and we’re always pleased with their service and their friendly, knowledgeable staff. We highly recommend them for anyone needing air conditioner repairs or maintenance. Thanks to Santiago for providing outstanding five-star service!

This winter in Denver, my furnace started acting up just when I needed it most. Even though it’s a new unit, there were a few issues that needed to be worked out. I’ve had a handful of repair technicians come by, all of whom were pleasant and helpful, but none compared to Carter! He was absolutely outstanding—extremely professional and truly went the extra mile to make sure my furnace was running smoothly. Carter was friendly, energetic, and took the time to explain everything about the repairs and what was causing the problems. He showed a lot of care and respect, making sure I understood what was going on with my heating system. Carter put in extra effort and didn't leave until he was certain I’d have steady, reliable heat through the cold. Even after finishing the job, he stayed in touch and checked in over the weekend to make sure everything was still working perfectly. It was amazing to get such attentive, hands-on service. I also want to mention Walter, who helped schedule and coordinate my service. Walter was organized, professional, and very kind, making the whole process easy and stress-free. If you’re in Denver and your furnace needs some attention, I highly recommend asking for Walter to set up your appointment and Carter to handle the repair. Thanks to their great service, I feel so much more confident in my furnace and my choice to invest in it!

We first contacted Harmony Heating & Air Conditioning for routine maintenance on our air conditioning system. Our AC is an older model that still uses R22 refrigerant, and every other company we reached out to told us we’d have to replace the entire unit since R22 is hard to find and expensive. However, Santiago from Harmony Heating & Air Conditioning took the time to clearly explain all our options and what could be done to keep our system running. We decided to have the AC serviced instead of replacing it right away. While working on the AC, the technician found that our heat exchanger had developed cracks and was leaking dangerous carbon monoxide into our home whenever the heater was on. Thankfully, this was caught in time and we feel like it made a huge difference for our safety. Because of this, we went ahead and replaced the entire HVAC unit, and the AC was serviced so it could be updated to use a new refrigerant if needed in the future. Now everything is working great and we feel much more secure. We were very impressed with how knowledgeable and professional the team was. They arrived right on schedule, responded quickly to questions, and offered a solid warranty on both the system and the work done. When we needed help with an insurance claim, they assisted us through the process and even followed up the next day to fix a minor issue—a loose wire in the AC. We are extremely happy with the service and highly recommend them to anyone needing HVAC work!

Our HVAC sys is three years old now and Absolute maintains all aspects perfectly. Thank You team Frankie for being the best pros ever in Denver. My plumbing systems are in perfect condition

Diego and his crew did an awesome job.
They were very respectful, efficient and professional with replacing my toilets.

Ricardo was great. He just came to do an HVAC inspection. He did find a small issue, which he showed me and fixed in 30 minutes. This was great service at a reasonable price. However, last year they tried to charge me $400 for a new disposal, which was a complete ripoff.

The two electricians who came worked hard, were friendly and were respectful of my space. They hung my crystal chandelier and some new fan lights as well as adding circuits in the garage for 2 plug-in hybrids and a freezer. I’m happy with the job they did.

Tobias was such a great electrician! He was very thorough, explained the work being done and was extremely efficient! I appreciated the full day of work he put in to rework all the outlets in my home. Very nice young man and even had the forethought of understanding my meetings for the day so he wouldn’t interrupt my power or internet service.

Had Jeremy take a look at our plumbing to make sure everything was good and he did a fantastic job! So friendly and dedicated to his craft/trade. Thank you Jeremy and team Absolute!

Micheal with Absolute Plumbing was great. He was very efficient, timely, explained things about the problem very well and cleaned everything. Very happy with the service. The front office was great to work with and it was very easy to set up an appointment. Would highly recommend Absolute Plumbing.
