All reviews for Fusion Heating & Air Conditioning

I recently had four of the Mitsubishi HVAC systems installed in my Boulder home. Originally, I was only contemplating air conditioning, but after a conversation with Chris, the sales consultant, I decided on the heating/cooling units. The HVAC systems are outstanding. On a chilly morning of 18 degrees, my Boulder home was a comfortable 70* without the necessity to use my old-fashioned boiler. I'm extremely satisfied with the HVAC system, the sales consultant, and the technicians he sent. They were polite, on time, and neat. They put covers on the floor and furniture to protect from dust caused by the holes they were drilling. They even offered to vacuum the areas afterwards - a first for any contractor I've interacted with. I would endorse them to anyone in need of HVAC repair or related services.

Jonathan and his team have been addressing my furnace repair needs for almost half a decade at two different residences. Shortly after I moved into my initial residence, my furnace gave up during an extremely cold spell. Jonathan spent a good amount of time with me over the phone on a chilly night, troubleshooting the issue. When it was clear that it was time to replace the old furnace, his team installed a new one the following day at a reasonable cost, a service many other repair companies might have exploited under such circumstances. The furnace operated smoothly for the duration of my stay in that house. In my new residence, Jonathan's team installed a cooling system and collaborated with me to ensure I was satisfied with the product. During the installation, they noticed a tiny gas leak due to the builder's use of an incorrect fitting on the gas line to the furnace. The leak was promptly fixed while they were still at the house. This was a minor repair, but it demonstrated a level of customer service that is rare to find. They recently returned to service the furnace in readiness for the winter and discovered that my gas pressure was almost twice the manufacturer's recommendation. I was happy to see them come out and ensure the system, newly installed by the builder, was adjusted to operate correctly. Jonathan always takes the time to understand your needs and comes up with solutions to address them. Eddie, one of the service technicians, is punctual, courteous, and knowledgeable. They complete the job with honesty and ensure you are pleased with their services. I strongly endorse this team to anyone with furnace repair needs in Boulder.

Eddie was incredibly prompt and systematic during our furnace repair process, making the entire experience smooth for us. Our job was somewhat complex due to the structure of our ducts, but Eddie and his team showed great dedication, working late into the evening to ensure everything was perfectly set up, all done within a single day. The newly repaired system has been functioning excellently so far, and we anticipate that the need for oil as a backup will be minimal as the furnace can operate efficiently even at 15F. We would highly recommend their services to anyone in Boulder looking for reliable furnace repair or HVAC services. Say goodbye to fossil fuels!

I needed a repair for my commercial furnace in Boulder. I called and Chris came out right away to fix the problem at a very fair price. What really stood out to me was how quickly they responded—faster than I expected. Chris figured out exactly what was wrong with the furnace in just a couple of minutes and had it working again just as fast. He was not only quick but clearly knew his stuff. I’m not a furnace expert, but I could tell I was dealing with a real professional. The cost was reasonable, and I felt good paying for such great skill and service. I’ve had the same positive experience when they worked on my home furnace as well. When the owner is out working alongside the team, you know you’re dealing with a company that truly cares. If you need furnace repair, these guys are fast, knowledgeable, and honest. I highly recommend them!

After many summers struggling with heat building up on the second floor of my house, I decided it was time to look into AC repair and installation to help cool things down. I spent quite a bit of time researching different types of cooling systems and felt ready to discuss options and pricing. When Jonathan from Fusion Heating & Air Conditioning came by, he listened carefully to my research and concerns, and patiently explained which air conditioning options would work best for my home. His advice was spot on! We went with a system that included variable speed fans and a special fan mount that really cuts down on noise. Jonathan also added extra venting to the roof, so now we can get rid of trapped hot air in less than an hour. With the hot summer days we've had, the new AC system has made a huge difference. Jonathan has even checked in after the installation to make sure everything is running smoothly, which I really appreciate. I felt comfortable having him work in my home, and he always made sure to leave everything clean and tidy. If you’re thinking about any AC repair or installation, I highly recommend putting this company on your list.

The team did an outstanding job getting me set up with a new Carrier HVAC unit. Jonathan helped me find a great deal, and the installation was completed right on schedule, fitting perfectly with my busy days. The installers, Chris and Axel, were very professional throughout the whole process. They reinforced the spot where the air handler was installed, made sure everything was secure, painted the area, and left the space spotless when they finished. Jonathan also took the time to explain how to use my new thermostat, even though I bought it somewhere else a few months ago. I really appreciated the extra help. I highly recommend this company to anyone looking for HVAC services. On top of everything, they saved me over $700 compared to another quote I had received. Excellent service and great value!

I had an AC mini split system put in for a room above my garage that was getting way too hot in the summer. Chris from Fusion Heating & Air Conditioning came by a couple of times before the installation to answer my questions and walk me through what I needed to get ready. On installation day, Jonathan, Eddie, and Chris arrived right on time, explained what they were going to do, and answered all my questions along the way. Jonathan made sure I liked how everything looked and showed me how to use the new AC to get the best performance. They also helped me with all the paperwork to get a rebate and made sure I was completely satisfied with the install before leaving. The new unit runs so quietly that I barely notice it's on, but it keeps the room perfectly cool even during those hot Colorado days. From getting the initial quote to finishing the job, everything was straightforward and smooth. The team was friendly, honest, and focused on making sure I was happy. If you need any AC repair or installation, I highly recommend giving them a call.

Absolutely fantastic service! I called to have my old HVAC system looked at (it’s been running for over 20 years), and a technician showed up in Boulder the very next day—even though it wasn’t an emergency. Chris treated me and my home with great respect and managed to fix my aging unit rather than pushing for a replacement, which I really appreciated. In HVAC, it’s common for some companies to suggest getting a new system right away, but honesty is key, and Chris definitely delivered. I’ll be using them for all my heating and cooling needs from now on. I’m already setting up a furnace maintenance appointment with them, and when it’s eventually time for a new system, I know exactly who I’ll call. Five stars for reliable, honest work!
