Reviews of local pros in Boulder, Colorado

I wanted to share my experience with Fusion Heating & Air Conditioning when I called about scheduling an annual maintenance for my mom's oil furnace in Boulder. I really appreciated speaking with a real person right away instead of dealing with an automated phone system. The staff member, Eddie, was friendly and professional, making it easy to set up an appointment. I was pleasantly surprised to get same-day service. When the technician, Jonathan, arrived, he was courteous and knowledgeable. He took the time to explain the furnace maintenance process and made sure everything was running smoothly before leaving. Overall, I was very happy with the prompt and professional service for our heating system. I would definitely recommend their HVAC services to others in the area.

Both of my air conditioning units stopped working one after the other. Eddie gave us a fair and affordable estimate for the repairs. He took the time to sit with my husband and me to explain how their service plan works, and was very understanding about payment. Since we couldn’t pay all at once, he helped us with financing options that didn’t have any interest for the first part of the term. The team was careful to protect our floors and kept everything tidy while they worked. Before the installation started, Eddie even set us up with a temporary AC unit, which was a lifesaver since my daughter likes to stay in her room when it’s hot. The crew was friendly, flexible, and really focused on making sure everything was done right. I would absolutely recommend Fusion Heating & Air Conditioning for anyone needing AC repairs.

Thank you for the great service! My air conditioning system stopped working, and I was able to schedule an appointment quickly. Jonathan, the technician, arrived on time and was extremely knowledgeable about HVAC systems. He quickly diagnosed the problem and was not afraid to get his hands dirty. It turned out that when my solar panels were installed, the other technicians had accidentally caused an issue in my power box. Thanks to Jonathan’s expertise, he fixed the problem right away, saving me from needing to call an electrician and spend more money. This was by far the best HVAC service experience I’ve had in a long time. Highly recommended!

We are really happy with the service from Fusion Heating & Air Conditioning. From the start, the team has been honest, hardworking, and reliable. Their technicians always show up on time and treat our home with respect. During our recent spring AC tune-up in Boulder, Eddie and Jonathan did a fantastic job. They found that our furnace fan needed cleaning and also noticed the air conditioner’s capacitor was starting to go bad. While Eddie took care of cleaning the fan, Jonathan quickly picked up a new capacitor and installed it right away. Thanks to their maintenance program and regular checkups, we’ve never had problems with our heating or air conditioning. Our equipment runs more smoothly, uses less electricity, and seems to last longer. Plus, after upgrading to a whole house humidifier and UV HEPA filtration, our family’s allergy symptoms have improved a lot. The service here is always professional and knowledgeable, making us very satisfied customers.

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!

Axel had quite the task during his recent visit to my home to repair my furnace. Many of the furnace units in my building aren't labeled, which made finding the right one a challenge. But Axel stayed calm and used his experience to quickly locate and fix my furnace for a fair price. He was efficient, knowledgeable, and handled everything with professionalism and integrity. Axel listened carefully to my concerns, thoroughly checked the furnace, and explained my options clearly. You can tell he is passionate about his work and has a lot of experience in furnace repairs. I highly recommend Axel and will definitely call again if I need any furnace work done. Five stars!

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.

eddie serviced our furnace this afternoon. he called ahead to let me know he was on his way and arrived right on time. he was friendly and really knew a lot about hvac systems. he worked fast and explained everything clearly, answering all my questions. eddie was patient with me and my kids when they got home and started asking about the furnace. what stood out most was how respectful he was of our home—he made sure to clean up after finishing the job. i would definitely recommend their hvac services to anyone looking for reliable and professional help.

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!

Fusion Heating & Air Conditioning installed a new heating and cooling system in my older mobile home. When I returned home after being away for several months, my thermostat showed an error and my HVAC system wouldn't turn on. The house stayed chilly at night, and I had to use a space heater and extra blankets to keep warm. I first tried my home warranty company, but after a few days, they said they couldn't find anyone to help and told me to find a contractor myself. I looked up Fusion Heating & Air Conditioning and called them. Chris answered right away, just like the first time I reached out. Even though he was busy, he took the time to help and remembered my installation. He explained my warranty coverage and made it easy to set up an appointment. Chris sent someone out quickly to check the system and figure out if it was a thermostat issue or something else. The system has been running great since it was installed, and I appreciate their quick response and helpful attitude. The service was fast, professional, and made me feel like a valued customer. I highly recommend them for anyone needing HVAC repairs or service.

I can't say enough good things about this furnace repair company. I had worked with a different place before, and the difference was huge. Axel was my technician and he did an outstanding job. I even had them come out to check on my mom’s furnace as well. My mom is an elderly widow, and unfortunately the other company overcharged her and installed a furnace that was way too big for her house, with piping that wasn't up to code. This team was prompt, knowledgeable, and took the time to explain everything clearly. Axel let us know which repairs were urgent and what could wait, which helped a lot. It was refreshing to work with such an honest company, especially when it comes to something as important as a furnace in Colorado, where cold winters mean you need reliable heat. The prices were very fair, and I truly recommend them to anyone needing furnace service. Just an incredible experience all around.

We were really impressed with how carefully the team checked every part of our old central heating system, including inspecting all the ductwork in the tight crawl space under our home. They also figured out the best way to add new ducts and vents to two rooms that never had them before. The installers, Chris and Axel, were extremely professional and paid close attention to all the small details during the installation. A couple of weeks after the job was done, they even followed up to make sure our new heat pump system was running perfectly and keeping our home comfortable. We’re very happy with our new heating and air conditioning setup. The folks here are friendly, knowledgeable, and I’d gladly recommend them to anyone looking for HVAC help.

We’ve depended on Fusion Heating & Air Conditioning in Boulder to take care of our home’s AC repairs and maintenance. Their team has kept our old air conditioning unit working smoothly with timely fixes, and when it was finally time for a new system, they installed a full replacement HVAC setup for us. The technicians, including Eddie and his crew, were always professional, knowledgeable, and quick to respond. The office manager made scheduling and communication easy. I highly recommend their AC repair and installation services for anyone looking for reliable help in Boulder!

chris and axel truly made my day a great one! such polite and respectful young men, and they were very patient with an older lady who asks a lot of questions about furnace repair. they worked hard to make sure everything was installed just right, then took the time to clean up so well you couldn't even tell they had been here. i am really happy with my new furnace, which runs smoothly and is super quiet. i highly recommend this team for furnace repair and installation in boulder. this is the second time i've had them install a new furnace and thermostat, and i wouldn't call anyone else!

i had a great experience with this company when i needed furnace repair and installation. they replaced my old furnace and were quick, professional, and left the area clean. the price for the new heating system was very fair. on another project, they put in a new furnace and made sure everything was done right, paying attention to all the details. axel, the technician i worked with, was very knowledgeable and friendly. the whole process was smooth and hassle-free, even though i wasn't able to be onsite. if you need reliable furnace repair or installation in colorado, i highly recommend them—they really deserve five stars!

I can’t say enough good things about Fusion Heating & Air Conditioning. When our furnace suddenly stopped working here in Boulder, right before we were heading out of town, Chris and his team came to the rescue. Their knowledge about furnace repair was clear from the start, and everyone was polite, respectful, and easy to talk to. Chris made sure to explain all the details in simple terms, answered every question we had, and kept us updated throughout the whole process.

If you’re looking for someone to fix or replace your furnace, you won’t be disappointed with their service.

i can't say enough good things about jonathan and axel, as well as the electrician, chris, they work with. these guys are truly experts when it comes to furnace repair in boulder. they were able to spot issues and answer questions that other hvac techs in the area couldn't help with. we had a major furnace problem caused by another company, and jonathan and axel came in and fixed everything the right way. they replaced old wiring, checked the heating system, made sure the furnace was running safely, and handled a few other repairs that were needed. in the middle of a cold colorado winter, they got our furnace working again so we could stay warm. they're not just knowledgeable, but also honest, reliable, and friendly. they explained all the options to us, went over the pricing, and shared their recommendations in a way that made sense. jonathan was always available to talk about what was going on and kept us updated on the progress. their prices are fair and reasonable for the quality work they do. plus, if you have pets, they are very respectful and careful as they work in your home. we're planning to have them back in the spring for more furnace maintenance, and some of our neighbors are interested too. highly recommend this team if you need furnace repair in boulder!

chris from fusion heating & air conditioning was extremely helpful when my furnace stopped working. he really knew his stuff and quickly found the main issue with my heating system. he used all the right diagnostic tools to figure out the problem fast. after changing an electrical part in the furnace and making sure everything was running right, my heat came back on without any problems. chris also clearly explained the repair options and costs since my furnace is pretty old. if all their technicians are like him, i’d definitely recommend this company for furnace repairs, especially when you need reliable heat during colorado’s cold winters.

They were hardworking, respectful, and took the time to explain everything about the furnace system and answer all my questions. I’m very impressed with their professionalism and would definitely recommend them for any furnace or HVAC repairs. Axel, Chris, Eddie, and the rest of the crew were all fantastic.

after getting two estimates for my plumbing problem—one for $495 and another for $395—i decided to call this company, and i’m so glad i did! ezra was very friendly and really knew his stuff. he didn’t just clear my clogged sink, which was why i called in the first place, but also noticed my toilet was wobbly and leaking when flushed. ezra tightened the screws and made sure everything was working properly, all at no extra cost. i’ll definitely call this company for any plumbing or heating needs in the future. on top of that, ezra recommended a specific type of toilet seat. when i went to the store to pick one up, the person there took the time to explain the differences between seats and even showed me how to install it. it’s been a long time since i’ve had such great customer service from start to finish!

When I was about to leave for work, I suddenly heard the sound of water running under my house. I checked my crawlspace and could hear the water but couldn’t find where it was coming from. After calling a few other plumbing companies who said they couldn’t come out for several days, I finally called a local plumber. Melvin arrived at my home in less than an hour, which was really impressive. He quickly found the leaking pipe and had it fixed fast. The whole job was finished in about an hour. I’m definitely keeping their number handy for any future plumbing problems. Highly recommend—5 stars!
