HVAC reviews in Denver, Colorado

I switched to a new hvac company several years ago after a bad experience with another provider who turned off my heat and tried to push me into buying a new furnace. i really wanted a trustworthy, local hvac team that wouldn’t take advantage of me. ever since making the switch, i’ve been very happy. this company has helped me through two homes, replaced two air conditioners, done regular maintenance visits, taken care of preventive repairs, installed a UV air purifier, and even did a whole house duct cleaning. their technicians, like james and brody, are always knowledgeable, friendly, and super professional. i trust them with all my hvac needs and wouldn’t go anywhere else.

I reached out for an estimate since our heater was nearing 24 years old, and I wanted to avoid any breakdowns this winter. A technician arrived right on time and started working on the estimate. During our conversation, I discovered that it was actually the owner of the company, which is quite rare! A couple of weeks later, Dwayne came to replace our system. Within just a few hours, he had the new heater installed. He cleaned up thoroughly and mentioned he would return the next day. When he came back, the entire system was up and running smoothly. Dwayne also helped us set up the new programmable thermostat. A few days later, we received all our paperwork in the mail along with clear instructions for submitting our rebate forms. I would definitely choose them again; they were efficient and completed the job on schedule.

I've been using ComfortFlow HVAC Service for several years. Their work is always excellent and the prices are reasonable. What stands out most is their HVAC technician team. Today, Brody came by for my routine HVAC maintenance check. He showed up right on time, which I really appreciate, and clearly explained what he planned to do before getting started. Afterwards, he reviewed everything he completed. Brody is very knowledgeable and answered all my questions, making sure I understood how my system works.

We had our AC system installed several years ago when our old central unit failed during a hot spell. Since then, we've had them come out a couple of times: first to handle our propane water heater replacement and just recently to fix an issue with our AC not cooling as it should. It was 92 degrees inside our house! The technician, Dwayne, was the last stop on what must have been a long and hot day, yet he arrived with a friendly smile and got straight to work. He spent nearly two hours on the outside unit in the blazing sun, replacing a faulty part and ensuring everything was running smoothly. We discovered this service through the Home Advisor website and felt confident after reading positive reviews about their commitment to going the extra mile. We can’t say enough good things about the friendliness, professionalism, and skills of their team. Each time we reached out, we spoke with a bright and knowledgeable voice—this time it was James—who was quick to answer our questions and worked hard to get us a same-day appointment given the heat inside our home. Whenever we scheduled a visit, the technicians called ahead to let us know they were on their way. Each one demonstrated great manners, a strong work ethic, and pride in their work. We particularly appreciated seeing one of the team members crawling around to clean up water drips after removing our old water heater. It may seem small, but it shows how much this company values creating great experiences for their customers. Both sides benefit: a happy customer is likely to return and may even refer new clients! It's all about building a relationship. We highly recommend their AC repair services!

i had a great experience with this heater repair service in denver. i needed a new heat pump for my home, and i was really pleased that scheduling an appointment was easy and it was confirmed quickly. the technician, james, arrived right on time and really knew his stuff when it came to heater repairs and installations. he explained my options clearly and provided two detailed quotes, and the price i chose was exactly what i paid—no surprises. the team that came out for the installation was also punctual and made sure everything was installed safely and up to code. they were friendly and professional, which made the whole process smooth and comfortable. everyone i interacted with from this company seemed honest and knowledgeable about heater systems. living in denver, reliable heat is so important, and i’m glad i found a company i can trust. i highly recommend them to anyone who needs heater repair or installation.

I highly recommend this company! They arrived right on time and stayed until the HVAC job was completely finished, even though it took over two hours. The technician, Dwayne, was very professional and courteous. Thankfully, he was able to get my air conditioning working again, and I finally slept comfortably after dealing with the heat. Now, the system is running smoothly, and cool air is coming through the vents just like it should. I'm happy with the service and would definitely call them again for any HVAC needs!

I had a fantastic experience with this AC repair team from start to finish. I’m finishing up my small and tight basement, which has some creative construction that made it tricky to reach the supply and return air ducts. James came out and gave me a detailed quote, making sure to explain everything and answer all my questions. It really felt like a collaboration, not just a standard sales pitch. Another company told me the job would require tearing out all the bulkhead framing and paneling, lowering the ductwork, doing the work, and then putting it all back up—which made me pretty nervous. James, however, said their team could work around my basement’s setup. On the day of the repair, Brody and Dwayne arrived right on time. They weren’t put off by the cramped basement and were super flexible, even working around my schedule since I had meetings. They did run into a spot where they had to remove some framing, but they handled it without any complaints or making it a big deal. They just got the job done quickly and with as little disruption as possible. They even made sure to keep up my cat prevention mesh around the new ductwork, which was above and beyond what I expected. When they finished, my basement was actually cleaner than before they started. I highly recommend this team for any AC repair, especially if you have a job that other companies think is too small or complicated. I’m really glad I found them!

I highly recommend these guys for heater repair. My heater stopped working right when it got really cold, and they were the only ones who could come out quickly to fix it. They made sure my heating system was running again so I could stay warm, and then later replaced both my heater and thermostat. They gave me a clear estimate fast, scheduled the work soon after, showed up early for the installation, and finished even quicker than promised. When there was a small problem with the new thermostat (which was a device issue, not their fault), Brody came back within an hour and took care of it. Their prices were very fair, they use high-quality parts, and their warranty is actually reliable, which is better than what you get with some other places.

I called ComfortFlow HVAC Service to help upgrade my furnace system by replacing my undersized ductwork, so I could get better airflow for my forced air heating throughout my house. At first, there was a small mix-up with one of their calculations, but they went above and beyond to make sure everything was fixed quickly and done right. Their communication was excellent, and everyone was easy to talk to and work with. Dwayne handled the sheet metal work, and his skill with ductwork and knowledge about air flow really showed. That's one of the main reasons I chose this company. I used to work as an HVAC service tech myself, so I know how tricky handling sheet metal can be—you definitely want experienced pros for the job. Overall, the customer service was top-notch, and I was very happy with how everything turned out. If I need more furnace work in the future, I’ll definitely call them again.

James is someone you can really trust for furnace repair. He knows a lot about heating systems and always puts the customer's needs first. James understands that everyone has different situations and is always fair with his work. He looks out for his customers by finding ways to save money, like offering good used parts for repairs when they are available and if you want them, but still making sure everything is high quality. We always go to James for our furnace and HVAC services because we know he will give us honest advice and do a great job. He has helped us with duct cleaning, furnace maintenance and repairs, in-duct humidifier service, water heater service, and some other small jobs.

I usually don't write reviews, but I had such a great experience with my furnace cleaning that I wanted to share. This was my first time using this company for furnace service, and they sent Brody to do the job. I was really impressed with how thorough Brody was—he did every step needed for a proper furnace cleaning and took the time to answer all my questions. I will definitely ask for Brody again the next time I need my furnace or air conditioner cleaned. The customer service was excellent, and now I see why they get so many five-star reviews.

I got my HVAC system through ComfortFlow HVAC Service. Dwayne came out and gave me three different options for new units. There was a small mix-up about which air conditioner I would get, but Brody, one of the installers, took the time to explain everything clearly. He was very patient and thorough. Both Brody and James did a great job installing my new AC and furnace. I’m really satisfied with the whole process and would definitely recommend them. The price was fair and they even included a few free filters.

Yesterday, we had a new high-efficiency heating system installed in our Denver home to replace our old heater. The team recommended a reliable Amana furnace with an Ecobee thermostat, and I’m really glad we went with their suggestion. James led the installation crew, and everything went smoothly and right on schedule. The new heater is already keeping our house warm and comfortable, which is important here in Colorado. James also took the time to show us how to use the Ecobee thermostat, explaining its energy-saving features and how we can adjust the heat remotely from our phones. We’re very happy with the service and the results. Great job by the whole team!

I called early in the morning because my heater stopped working. ComfortFlow HVAC Service quickly sent Brody and James over to help. They gave me a quote for a new heater and made sure I would get it installed the next day. I had to go one night without heat, but they left me some space heaters, which kept me comfortable. The team arrived at 8am in Denver with my new heater. They were very friendly, professional, and didn't mind my pets walking around. Brody and James took time to explain everything and did an excellent job with the installation. They worked carefully, cleaned up everything, and even brought a small care package to start my day. I am really impressed with the service and the high-quality work they did.

Our furnace stopped working suddenly. We left a message in the evening, and they called us back the next morning. That same afternoon, Brody came out to look at our furnace and was very professional. Just two days later, a new furnace was installed. The team arrived right when they said they would, laid down drop cloths to keep our floors clean, and took care to install new copper piping, a new thermostat, and a fresh filter. Everything was done efficiently and with great attention to detail. It’s rare to find service like this these days. We’ve worked with this company since we built our house, and while we haven’t needed them too often, every experience has been excellent. When our old furnace finally needed to be replaced, they made the whole process smooth and stress-free. Highly recommend for anyone needing furnace repair or installation, especially in Colorado where reliable heat is so important!

We recently needed help when our furnace stopped working. James came out to our home and did a fantastic job explaining everything in a way we could understand. He was very thorough, checking over the whole system and answering all our questions. We ended up getting a new furnace installed, and the price was very fair. The installation was done professionally and James kept us updated every step of the way. This company is very reliable and honest. We’re extremely happy with the work they did and will definitely trust them for any furnace repairs or maintenance in the future.

We are very pleased with the heater repair service we received. We needed to replace our old furnace, and the company gave us a price that was almost $1,000 lower than other quotes for the same model. They also included extra duct work improvements, which made the heat flow much better throughout our home—other places didn’t offer that. We appreciated that there was no need for an expensive yearly service membership, unlike some other companies. Brody, the technician who installed our new furnace, was very skilled and professional. When I noticed a small issue after the installation, he arrived within 30 minutes and fixed it right away. Overall, we are very satisfied with the service in Denver.

When my furnace stopped working, I spent a lot of time researching different repair options. I got quotes from three places and chose this company for the job. James and his team arrived on time and were very professional and friendly. They made sure to keep everything tidy while working and finished the furnace repair quickly—just about three hours. After they were done, you couldn't even tell anyone had been working in the house. They also installed a new WiFi thermostat, which took me a bit to figure out, but it works perfectly now and I really like the upgrade. I'm very happy with my choice and the whole experience. Highly recommend for anyone needing furnace repair, especially if you want the job done right and fast.

My wife and I recently moved into a fixer-upper in Denver, and one of the first things we needed to take care of was replacing the old furnace. Brody, their estimator, came out to take a look and put together a quote for us. While he was here, he noticed we were using a space heater just to keep warm. We decided to go ahead and order the new furnace, and Brody let us know it might take a few days for the new unit to arrive, with installation scheduled for sometime midweek. To our surprise, Brody called us on Friday to say the furnace had already arrived, and he could come out that same day to install it if we were home. We were thrilled and said yes right away. Brody showed up, got to work removing the old furnace and installing the new one, along with a new thermostat, and finished everything quickly. As he was tidying up and heading out, he told my wife he didn’t want us to go through the weekend without heat. That really showed how much he cared about making sure we were comfortable. The furnace works perfectly and has made a huge difference in our home. We’re very happy with the fast, caring service. This company is definitely a 10 out of 10 in our book!

After having some trouble with my old furnace and leaky, poorly insulated heating ducts, I decided it was time for an upgrade. I got a couple of quotes, and while one company offered a cheaper option by skipping some steps, I’m really glad I went with this team instead. They made sure to seal and insulate all my ducts properly and installed brand new insulation under the floor for just a little extra cost. Brody, the lead technician, also suggested I get my crawl space rodent-proofed since I’ve always had issues with mice, and he even noticed that my dryer duct needed replacing because it was venting into the crawl space. Now, for the first time since moving in, I don’t have to worry about freezing pipes, broken dryer vents, or insulation problems under my house. Even a carpenter friend took a look and said Brody and his crew did outstanding work. I really appreciate their attention to detail and how they made my home much safer and warmer for Colorado winters.

After having trouble with our heater for a couple of weeks, we decided to call for heater repair service. James came out the next morning and quickly figured out what was likely wrong with our old furnace. He gave us a quote for replacing the furnace, AC, humidifier, and even adding an air purifier. James was very knowledgeable and easy to talk to. He made sure his team could fit us in quickly, so we got our new heater installed just a few days later. The crew that put in the new furnace, Brody and Dwayne, were also very skilled, worked fast, kept everything clean, and took the time to explain how everything worked when they finished. Our home feels much warmer and more comfortable now, and we’re looking forward to getting the AC put in soon. Our whole experience was fantastic, and we definitely recommend them for any heater repair or HVAC needs.
