HVAC reviews in Longmont, Colorado

ComfortFlow HVAC Repair provided excellent service at an unbeatable price. After moving into our new home, we discovered that we needed a new furnace and complete ductwork replacement. We received six quotes, and ComfortFlow's was the best by far. Their team was punctual every day, and my basement is even tidier than before they started. They installed a new furnace, ductwork, humidifier, and thermostat, ran three new supply lines (including one to the second floor), and set up a 4-ton whole-house A/C unit, all in just four days! So far, everything is working great, and I look forward to recommending their services in the future.

my husband and i can't say enough good things about the heater repair service. connor and his team are true professionals. connor was very responsive from the start and kept in touch with us before, during, and after fixing our heater. his repair team was great; they made sure everything worked right, showed up on time, respected our home, wore masks, and cleaned up after themselves. connor also stopped by after the repair to show us how to use the heating system efficiently, and he handled all the paperwork for rebates. we like to support local businesses when we can, and we highly recommend this heater repair company (we've already told two other homeowners about them and will keep spreading the word!).

I had a fantastic experience with my heater repair. I called on a really hot day because my heating system wasn’t working. I was told there were a couple of customers ahead of me, but someone could come by in the afternoon, and they did—same day service! Maurice walked me through some troubleshooting steps on my complex heating system, which involved connections to the power grid and a solar energy setup. He pinpointed the issues and got everything working smoothly again. It’s wonderful to call, speak to a person, and have that same person come to fix the problem. Great service!

when my husband and i got home to our place in longmont one evening, we noticed right away that it was much colder than usual inside. i looked at the thermostat and saw the heater wasn’t working—there was an error about no power to the unit. we tried calling a bunch of companies that say they offer 24-hour service, but none of them could actually come out to help. our 17-month-old daughter was shivering and pretty uncomfortable, so we really needed someone fast. while searching for help, my husband found a local company and got in touch with terry. terry picked up right away, asked a few questions, and helped us try to figure out what might be wrong with the heater. then, terry came out to our house in longmont later that night. he quickly found out why the heater had lost power and fixed it on the spot. terry gave us great service—he’s really knowledgeable about heater repair and was super honest about everything. we’re very thankful for his help and will definitely use this company for any future heater or furnace repairs. if you need your heater fixed in longmont, we highly recommend them!

i had a new hvac heat pump system installed at my home. what a great experience from start to finish. connor was the estimator and he was very honest and thorough, taking the time to explain all the details about the heat pump and what to expect during installation. maurice and terry, the technicians, were professional and friendly. they answered all my questions, used drop cloths to keep my home clean, and even showed me how to use the new thermostat and system. the office staff was also super helpful whenever i called. i’m very happy with my new hvac system and would definitely recommend this team to anyone looking for quality heating and cooling work.

i’m so glad i finally contacted ComfortFlow HVAC Repair for help with my heater. after dealing with heater problems for months in longmont, including two other companies that just tried to sell me a new unit with no real answers, i was getting frustrated. my heater kept breaking down, and each time it was hard to get anyone to really figure out why. then i called, and they sent out jason, one of their technicians. he was really friendly and definitely knew his stuff. he checked out my heating system, did a full diagnostic, and explained everything in simple terms. later, connor stopped by to double-check everything and make sure the right fix was being done. they both took the time to find out what was really causing the issues instead of just pushing for a new heater. they fixed the problem and now my heater works great. i’m happy with the service and would definitely recommend them to anyone in longmont needing heater repair!

we had a massive old furnace in our Longmont home that other companies said couldn't be replaced. but when we reached out for help, maurice came by and right away said it was possible. connor and terry did an amazing job—they carefully took out the old furnace (which was so big it needed a forklift!) and set up our new one all in a single day. they handled everything, from putting in new venting to installing the chimney liner, gas piping, and electrical connections. the team really knows furnace repair and made sure everything worked perfectly. can't recommend them enough!

when my old furnace stopped working and we lost heat at home in longmont, i reached out for help. i got a quote for a full furnace replacement, including a new propane furnace, a 4 ton air conditioner, and an aprilaire humidifier. the price was fair and made sense for all the work needed. after i accepted the estimate, all the equipment was delivered quickly. even though they were busy, the team managed to send out about five technicians, including maurice, to handle the installation. the crew finished getting the furnace up and running in just one day, so our heat was back fast. they worked neatly and cleaned up everything, taking away the old equipment and leaving the area tidy. the whole process was smooth and professional. i highly recommend them for any furnace repairs, maintenance, or replacement jobs.

the technicians who repaired my heater were top notch! service was excellent from start to finish. i’ve had a great experience with comfortflow hvac repair right from the beginning. i highly recommend them if you need heater repair or similar services! in a time when good customer service is hard to find, it’s a pleasure to share my positive experience. the heater repair team was absolutely fantastic, but i also want to thank jason, the sales rep, who made everything easy. from the moment he came to my home in longmont to talk about my heating options, and even following up after the repair, jason was professional, friendly, and really listened to my concerns. he explained everything clearly and showed a lot of honesty and care. companies need more folks like jason. great job to him and the team for making my heater repair experience so smooth. keep up the good work!

Our old furnace stopped working suddenly, so we got a few quotes for repair and installation. We chose a company in Longmont because their price was fair and they could install the new furnace quickly. They even called us to move up our appointment when another spot opened. Jason and Maurice, the technicians who came to do the job, were professional, friendly, and explained everything clearly. There were no surprise charges or pushy sales tactics, and they finished the installation in about four hours. The new furnace is running smoothly and keeping our house warm. I'm very satisfied with the service we received.

Our older cabin in Longmont needed a new heating system, and ComfortFlow HVAC Repair was the perfect choice. Maurice came out and gave us a clear plan for furnace repair and new ductwork, including adding a central furnace for downstairs and using ductless mini-splits in rooms where regular ducts wouldn’t fit. Everything was installed quickly and smoothly. Maurice made sure everything worked well and even checked in later to make sure we were comfortable with our new system. The whole process was easy and worry-free. We’ll definitely rely on this company whenever we need furnace help in the future!

Terry came out to my home in Longmont to repair my furnace. He was very professional, paid close attention to detail, and was always courteous. Terry kept me updated about the progress and let me know ahead of time when he would arrive. He even made extra trips to make sure the remote thermostat app was set up correctly, and worked with a technician to get all the features running smoothly. I’m very happy with the furnace repair and highly recommend ComfortFlow HVAC Repair for anyone needing heating services.

I had ComfortFlow HVAC Repair replace my air conditioner, and I can't say enough good things about the experience. From the start, the person who answered the phone was friendly and set up my appointment quickly. Maurice came out to look over my AC system, explained everything clearly, and made sure I was comfortable with the options and price. Later, Terry came to do the measurements and was very polite. When it was time for the installation, Connor and another technician arrived on time, removed the old unit, and installed the new one. They cleaned up every bit of debris so well that you wouldn't even know any work had been done, except for the new AC unit and the cool air coming through my vents. Connor explained how everything worked before they left. I really appreciated the fair pricing, professionalism, and the quality AC repair and installation.

I highly recommend this company for heater repair and installation. I needed help fixing or possibly replacing an old gas furnace in a small attic space, and also wanted a heat pump installed for the same area to create a dual fuel system. After getting a few quotes, I chose this company because their price was fair and they clearly knew a lot about heating systems. Besides the work upstairs, I also asked them to check out a heat pump on the first floor that wasn’t working, even though the gas furnace was still running fine. Terry and the team were committed to doing the job right, even when it took more time than expected. They explained every step, tested all parts of the system to make sure everything was working perfectly, and stuck to their original estimate even after putting in extra hours. Their communication was excellent—they always called the day before, sent text reminders, and let me know right before they arrived. They were also very respectful of my home and pets, and worked with me to manage the tight parking situation. The new heating system they installed works great, and the changes they made to the ducts and vents have made a big difference. Now, all the rooms are warm and comfortable, even during cold Colorado weather. I’m very happy with their service and the results.

ComfortFlow HVAC Repair really stands behind their work. I had them install both a four-ton and a two-ton Goodman HVAC system with gas furnaces in my home in Longmont. The larger unit has worked perfectly since installation, keeping our house comfortable through all seasons. The smaller system did have some refrigerant leaks, but whenever I called, technicians like Terry came out quickly to fix the issue. When the condenser on the smaller unit stopped working, they honored the warranty and replaced it with a brand new one the very next day, all at no extra cost. The service was prompt and professional, and I appreciate how they made sure everything was running smoothly. Great experience overall!

ComfortFlow HVAC Repair responded right away when I reached out about my heater not working. They were able to set up an appointment for me quickly, which was great since it gets pretty cold here in Longmont. Jason, the technician who came out, let me know up front about the cost of the service call, and I really liked how honest and clear he was. During the appointment, Jason was very thorough in checking all parts of my heater. He even went into the attic to inspect the system and made sure everything was running safely and efficiently. He explained everything he was doing in simple terms, so I understood what needed to be done to keep my heater working well through the winter. Thanks to his detailed work, my heater is now running perfectly, and my home is warm and comfortable again. Compared to other companies I’ve used before, no one has been as careful or knowledgeable as Jason. I highly recommend them for anyone needing heater repair in Longmont.

I highly recommend this company! I had trouble finding anyone to repair my furnace after it started freezing up, most likely because it was installed incorrectly by a handyman. Other places wouldn’t help or just kept sending me in circles. When I called here, the receptionist was very friendly and listened carefully as I explained the problem. The owner made sure a technician came out quickly. Terry and the team were professional and polite, and they had my furnace working smoothly again in just a few hours. They basically had to redo the whole installation since the previous work was done wrong, and they even made sure all the wiring was hidden and tidy. The furnace works great now, and I’ll definitely use this company for any future heating or cooling needs.

About two years ago, I had my furnace replaced by ComfortFlow HVAC Repair. Connor came out the same day I called, took the time to clearly explain what was wrong with my old furnace, and why a replacement was necessary. The new furnace was installed within just a day. Because I was so pleased with the service, I reached out to them again when my air conditioner started having issues recently. Connor came over to check out the problem, explained everything in simple terms, and returned the next day—even though it was a Saturday—to replace the AC unit. With how hot it’s been lately, I really appreciate how responsive and customer-oriented they are. Their quick and reliable service made a big difference in keeping my home comfortable.

Our air conditioning stopped working at home, and the first technician we spoke with said we needed a full system replacement at a very high price. Wanting a second opinion, we called around for more estimates. When we reached out, Maurice answered our call and was extremely prompt and professional. What started as just looking for a price quote turned into us becoming very happy customers. Maurice quickly diagnosed the real issue and got our AC working again, saving us thousands of dollars since a new unit wasn’t actually needed. The customer service was excellent—no pressure and no attempt to sell us anything extra we didn’t need. We highly recommend this team for anyone needing HVAC help.

We’ve had Maurice out to our house twice now for HVAC work. The first time, he came to service our air conditioning unit. Maurice was the only technician we’ve had who actually took the time to remove the fan blade and clean out all the leaves and debris, plus he did a thorough job cleaning the coils. He didn’t push us to buy a new unit, which we really appreciated, and he took the time to explain how to get the best performance from our A/C. Later on, when we needed to replace our old furnace and ductwork, Maurice was the first person we thought of. He offered us several suggestions to boost air flow throughout our home and was even willing to rebuild our existing furnace if we wanted. We ended up deciding on a new furnace. Before installing it, Maurice made sure to clean, seal, and paint the furnace closet, which was a nice touch. After setting everything up, he tested and adjusted the fan speeds for both heating and cooling. The improvement in air flow is incredible! Maurice even cleaned inside the vents and updated the vent covers so that our rooms cool off much more efficiently. The kitchen, which always used to get really hot in the summer, now stays comfortable thanks to the improved air flow. Maurice is honest, on time, keeps his work area spotless, and truly cares about doing quality work. The pricing was fair, too, and there were no unexpected charges.

When our heater started having problems, we decided it was time to get it replaced. I contacted several local heater repair companies to compare quotes. Terry from the company came to our home and was very professional, clearly explained the options, and quickly answered all our follow-up questions. Out of all the companies we spoke to, this one offered the best price, warranty, and service for our heater replacement. The appointment for the installation was set up quickly. The installers showed up on time and did a clean, careful job putting in the new furnace. Terry even stopped by twice during the day to check how things were going and see if we needed anything else. With their professionalism, fair pricing, quality work, and great customer service, I highly recommend this company for heater repairs and replacements.
