HVAC reviews in Denver, Colorado

Outstanding AC repair service! I reached out late at night about a possible gas leak in my air conditioning system and quickly got a response from Wyatt. Early the next morning, I received clear information on pricing, including a notice that weekend diagnostics cost a bit more and that certain parts might not be on hand until after the weekend. Around noon, Calvin showed up, thoroughly inspected all areas for gas leaks, and also serviced the AC unit at my request. The gas issue seemed to be from a faulty flame, which he fixed right away. My older unit was checked and found to be in good shape—no pressure to replace it! He also installed a new thermostat, since my old one wasn’t showing the full temperature. I highly recommend Full Spectrum HVAC Service for anyone needing AC repairs in Denver!

After getting a quote from another local company, I thought I wouldn’t be able to afford furnace repair for the house I just bought. Then I got a call back from someone, but at first, I didn’t think much of it. She was persistent and called again the next day, and I explained that the other estimate was too expensive for me. She convinced me to let Robert come out to take a look and give me an estimate. I’m really glad she did! Robert’s quote for the furnace repair was much lower than the other one I received. He also took the time to explain how everything would work with repairing my York furnace. On the day they scheduled the repair, Robert called to let me know he was on the way. I mentioned I was thinking about replacing the furnace with a heat pump, but I thought it was too late. He was very helpful and said he wanted to make sure I was happy with my choice. He checked the breaker box and explained the differences, then gave me a new quote for the heat pump, which I was happy with, so I decided to go with that option. A short time later, they came out and removed my old gas furnace and installed a new Rheem heat pump. The two technicians, Wyatt and Calvin, were very polite and respectful, and did a great job. Robert called the evening they finished to see if I had any questions, and even followed up the next day, which I really appreciated. He also met with me to go over the maintenance contract and explained how the thermostat worked, including the programming features. I highly recommend this company for any furnace repair or heating needs in Denver.

i needed to replace my old oil furnace with a new propane furnace, so i reached out to several hvac companies in denver for quotes. wyatt from full spectrum hvac service came by and clearly explained the installation process and the type of system they would put in. i was surprised that their bid was the lowest, since friends thought they’d be more expensive. they installed a lennox furnace and it's working great. the system is much quieter than my previous one—sometimes i don’t even notice it’s on. the final bill matched the original estimate, with no unexpected charges even after installation. overall, i'm really happy with the service and how smooth the whole process went.

i've had this company help me with my heater repairs and maintenance for several years now. every time, they've been clean, on time, and very professional. once, they also installed extra insulation in my attic, which really helped lower my energy bills during the cold colorado winters. today, i spoke with wyatt about possibly upgrading my heating system, and he explained all the options in a way that was easy to understand, without any pushy sales talk. nobody really enjoys having to fix or replace their heater, but i feel confident that i'm getting great service, honest advice, and good value whenever i call these guys for heater repair.

full spectrum hvac service is honestly one of the best hvac teams i’ve ever worked with in denver. over the years, they’ve helped me with everything from fixing my air conditioner to replacing my old furnace. calvin was especially knowledgeable and made sure everything was running smoothly. they really care about customers and do what they can to fit you in, even when things get busy. i understand installations and repairs take time, especially during peak seasons, but they always keep me updated and work hard to make sure my heating and cooling systems are in great shape. as long as they’re around, i won’t call anyone else for hvac service.

the service was outstanding from start to finish. we needed a new heat pump system for our home in denver, and Full Spectrum HVAC Service made sure the installation went smoothly. robert and the team were at our place for over 10 hours, working nonstop to make sure we didn’t go without heat for even one night. after installing everything, there was a small issue with the unit on startup, but they came back every day to troubleshoot and make sure we were taken care of. when they discovered the problem, the replacement part was supposed to take two weeks to arrive, but instead of leaving us waiting, robert talked to his supplier and managed to get the part the very next day. we had heat again right away. their follow-up and commitment to making sure everything was right was really impressive. you can tell they care about their customers and take pride in their work.

Our heat stopped working in the middle of the night and the house got pretty cold. With two little kids at home, we were really worried. We reached out to Full Spectrum HVAC Service and Wyatt called us back quickly and came right over. He fixed our heating problem and also did a full service on the furnace. Wyatt was great about showing us how to reset the system if it happens again. We were very happy with how professional and fast everything was done. We plan to use them for all our heating and AC needs in the future.

After having problems with my old heater, my home warranty sent out a technician for repairs. The first company couldn't help right away, but then a different team came out and checked everything. robert arrived quickly, figured out what was wrong, and sent in the work order the same day. Even though the home warranty process was a bit slow, robert and his team always kept me updated and explained everything in simple terms. They even scheduled the heater repair on their day off to make sure my family had heat. I was so happy with their service that I joined their maintenance plan before the new heater was even installed. Their heating repair service is top notch. If you want honest work, friendly people, and fair prices, you should definitely give them a call.

I don’t usually write reviews, but I really want everyone to know about Full Spectrum HVAC Service. Over the years, they have always provided top-notch AC repair and installation at my home and rental property. They are friendly, honest, and always explain everything clearly, which is so important after some bad experiences with other repair folks in the past. Calvin handled the installation of both our furnaces and air conditioning units and always did a thorough, professional job. Anytime I needed service, they responded quickly and fixed any problems without hassle. We talked to a lot of HVAC companies before choosing this one, and they stood out for their deep knowledge and patience in answering our questions. They also offered the best prices compared to others we checked. I’m really happy with their work and highly recommend them for any AC repair or service needs.

We called Full Spectrum HVAC Service after a friend recommended them for AC repair. The first time, our air conditioner stopped working in the middle of summer, and they answered our call quickly. Calvin showed up when he said he would and the price matched the estimate. He was very professional and friendly. We also needed help when our furnace quit working, and they came out right away, even on the weekend, and fixed it for a very fair price. The team is hardworking, honest, and knowledgeable, not your typical repair guys. I always tell people to call them when they need AC or furnace service.

My 30-year-old AC unit stopped working right when the weather got hot. I decided to get it replaced, and the company I chose focused only on the AC repair without pushing me to buy a new furnace too. Their price was better than the others I checked. They also have their own electrician, so I didn’t have to deal with any subcontractors. The team, especially Robert, was on time, clean, respectful, and did quality work. They replaced my AC unit and even installed an extra vent in my family room. Now our home in Denver is comfortable and cool. When my furnace needs work, I’ll call them again.

Robert and his team did an excellent job repairing my heater. When they took out the old unit, they found some mold, but Robert quickly put together a solid plan to get rid of it and kept the work moving smoothly. He even brought in extra crew members from other jobs to make sure my heater repair was taken care of right away and done correctly. Robert kept me updated throughout the whole process and explained every step, which really helped me understand what was happening. He went above and beyond to make sure my heater was working perfectly, even though my project was a bit complicated. I highly recommend their heater repair services to anyone looking for reliable and professional help.

Our furnace stopped working just as the weather started getting really cold in Denver. We called the company we usually use, but they said it would be at least a week before anyone could come out. I mentioned the problem to some friends and they suggested I try a different local furnace repair service. They were able to send someone out the same day. The technician, Wyatt, quickly found the issue and fixed it at a fair price. He explained what was wrong and let us know what to expect with our current furnace. Unlike some bigger companies that might have pushed us to buy a new unit, he was honest about our options. Later on, we realized we forgot to ask them to install our new thermostat while they were here. After struggling with it ourselves for a while, I called the company again and they sent Calvin out right away. He was very friendly and clearly knew what he was doing. The service was fast and professional both times. I definitely recommend this company for furnace repairs in Denver!

On one of the coldest days in Denver, our furnace suddenly stopped working and our house started getting really chilly. I called several furnace repair companies, explained our urgent situation, but the soonest anyone could come was in a couple of days. Both my wife and I are in our 70s, and since I am recovering from cancer, we really needed help fast. Wyatt from the company called me back quickly, and after hearing what was going on, he arrived at our home within a couple of hours. He quickly figured out what was wrong with our furnace and had it fixed in no time, so our heat was back on the same day. Wyatt was prompt, friendly, professional, and truly cared about our situation. We were so relieved and grateful for the outstanding service we received. I can't say enough good things about Wyatt and the team. He went out of his way to help us after a long day of work, and we truly appreciate it.

i recently had these guys out to work on my hvac system and they did a fantastic job. calvin fixed a leak in my air handler and installed a new air filter, making sure everything was sealed up tight. they also added a vent in another room, hooked up a new thermostat, and moved some ductwork around for better airflow. there was a lot to get done, but they handled it all really well. the team was super friendly and always let me know what was happening each step of the way. if there was ever any confusion, they explained everything clearly and made sure i understood. i already have a few more hvac upgrades in mind for the future and i know exactly who i’ll call. even before i needed any repairs, they were really helpful to me as someone new to the area. i like that you can easily send in requests online and they actually respond quickly, sometimes even coming by to check out the ac unit in person. overall, really happy with the service!

We had our old AC system removed and a new ductless AC unit installed at our home in Denver. Calvin and Wyatt handled the entire process—they worked quickly, kept everything clean, and were very respectful. It was great having them here, and we’d be happy to see them again for any future AC repair or installation needs. Later on, Robert came by to help us with some issues we were having with the new system. He explained everything clearly and showed us how to use all the features, including the WiFi and smart home setup. The service was outstanding from start to finish, and we couldn’t be happier with the work they did.

We have relied on Full Spectrum HVAC Service for many years for our heater repair and maintenance needs, and have always had a great experience. Recently, we needed to replace both our outdoor unit and furnace. Wyatt came out first to do a diagnostic check—he was very friendly, knowledgeable, and professional. Later, we spoke at length with the owner, who carefully explained all our options for new heating units without trying to push us in any direction. They gave us four clear choices on a detailed spreadsheet so we could make the best decision for our home. Once we picked our new unit, it arrived quickly. Calvin and Robert handled the installation, working hard over two days. They were always professional, courteous, and dedicated to making sure everything was done right. The team’s expertise in heater repair, regular tune-ups, and consistent, high-quality service is why our old system lasted so long and why our other units are still running smoothly. That kind of reliability is rare. If you’re considering replacing or repairing your heater, I highly recommend them.

We got four quotes for a new heating and air conditioning system. Each company came recommended, so we considered them all. When Wyatt and Calvin visited us, they gave a clear and detailed explanation of what our HVAC system needed and made sure we understood every step, even though we aren’t experts. Their estimate was the most affordable, so we chose them for the job. Their technicians—Robert, Robert, and Wyatt—were professional, friendly, and worked efficiently to install the new system, including all new ductwork, without disrupting our day. Calvin also checked in several times to make sure everything was on track. The new ductwork looks great—so much so that we’re thinking about leaving it visible instead of hiding it. I highly recommend this team for their fair pricing, strong work ethic, and excellent HVAC skills!

I recently had an excellent experience with a local company when my furnace stopped working during a cold spell. After spending weeks and a lot of money with another business, my home was still freezing and the furnace wouldn't heat up properly. I finally called this company, and they really impressed me with how quickly they responded—coming out the very same day. Robert, the technician, was very knowledgeable and professional. He took the time to check everything carefully and was able to repair my furnace right then and there. It’s been running perfectly ever since, keeping my house warm and comfortable. At first, I thought I might have to replace the whole furnace, which would have cost thousands. Robert explained the problem and said some parts could be replaced for a high price, but instead, he made a few adjustments and fixed it without needing expensive new parts. This saved me a lot of money. It was clear that they cared about doing the right thing instead of just making a quick profit. It's rare to find a furnace repair company that is so honest and dedicated. I highly recommend their services and would give them more than five stars if I could.

When our heater stopped working in Denver, we were worried about staying warm during the cold Colorado nights. We had another company come out before, but they couldn't fix the issue and never followed up with us. Then Robert from this company came to help, and the experience was so much better. He quickly found the problems with our heating system, explained everything clearly, and gave us a fair estimate for the repair. Robert fixed our thermostat, repaired a leak, and replaced a broken part so our heater runs smoothly now. He always answered our calls and texts right away, which made us feel taken care of. The price he quoted was the price we paid, and there were no surprises. Now our home is warm and comfortable again, and we are grateful for the excellent service.

i had full spectrum hvac service replace all my ductwork, and they did an outstanding job. the team was hardworking, friendly, and respectful the whole time. they made sure to answer all my questions about my furnace and kept me informed during the whole process. i'm really impressed with their service and would definitely recommend them for any furnace repair or hvac needs. wyatt, calvin, robert, and another technician were all fantastic. they had previously installed a new furnace for me and i was very happy with that work too. great company!
