HVAC reviews in Denver, Colorado

my heater stopped working one cold evening in denver, so i called for help the next morning. brendan arrived before 9 and was super polite and professional. he explained what could be wrong with my heating system and gave me a clear quote right away. turns out, i needed a new furnace, and they were able to install it the same day. matthew and herbert did a thorough job putting in the new furnace, and someone from the office called soon after to make sure everything was working fine and to answer my questions. i highly recommend this heater repair service!

After returning from a trip, we found that our AC was blowing warm air instead of cooling the house. Luckily, our air conditioning unit was still under warranty, so we wanted a company that was certified by the manufacturer. We found an AC repair team who was available over the weekend and came out quickly to help us. They got our system running cold again in no time. When our AC had a couple more issues, they responded the same day we called and always got things back on track. Eventually, they found the main problem and set up a repair at a reasonable price. We’ve been really pleased with how fast and professional their service is. Staying cool in Colorado is important, especially when the temperatures rise. We’ll definitely reach out to them again if we need AC repair in the future.

I can't just leave a simple 'Great service' review because this team really deserves more praise. I came back to my house in Denver after being away for a week, only to find it freezing cold inside. With two small kids and a dog, I needed the furnace fixed fast. My usual company couldn't help me soon enough, and other places I called were also booked up. Luckily, after searching online, I called this company and got to speak with someone right away. They quickly scheduled an appointment for the same day, which was such a relief. Ross, the technician who came out, was professional, efficient, and very honest about what needed to be done to get my furnace running again. He didn't try to push any unnecessary repairs or products, but instead gave me useful tips on keeping my furnace in good shape and making it last through the Denver winters—even though it's pretty old. Because of the great service and honest advice, I'll definitely be calling them again soon for a quote on a new furnace and possibly an AC unit.

Our home was in need of a significant furnace upgrade, so we started looking for HVAC companies to help us out. After talking with a few businesses and getting some estimates, we decided to go with Allied Heating & Air Conditioning—and it turned out to be a fantastic choice! The technicians, Ross and Herbert, did outstanding work, and Matthew, who inspected our old system at the beginning, was extremely knowledgeable and helpful. Our project was not an easy one, and some companies didn’t even respond because of the complexity, but this team took it on without hesitation and completely transformed our heating system. We are extremely happy with the results and now know exactly who to call for any HVAC needs!

Allied Heating & Air Conditioning recently removed my old furnace and installed a new gas furnace and air conditioning system in my Denver home. Ross and Brendan were the technicians who handled the entire process. From start to finish, everything went smoothly. They worked efficiently, were friendly, and made sure to keep the area clean during the installation. Once they finished, they took away all the old equipment and debris. The quality of their work was excellent. I highly recommend their furnace repair and installation services.

really great experience with this furnace repair team. they showed up on time, communicated clearly, and did exactly what they promised. when our furnace had water damage from the condensation line, ross went above and beyond to fix everything and replace the damaged parts. the crew worked hard and made sure our heating system was running perfectly, which is super important here in colorado. i highly recommend them for any furnace or heating repair. you can tell they care about their work and their customers.

I reached out through the website late one night because my air conditioner wasn't cooling my home in Denver like it should. I was pleasantly surprised when I got a call from your technician, Brendan, early the next morning—even on a weekend! Brendan arrived at my house within half an hour of our call and immediately started checking the AC system. He found out that the thermostat was the problem and needed to be replaced. Brendan was friendly, professional, and explained everything clearly. He swapped out the thermostat quickly, and soon my AC was running smoothly again. I really appreciate the fast response and Brendan’s knowledge about AC repair. Great service, especially on a Sunday!

If you need HVAC service in Denver, I highly recommend calling this company for honest and reliable help. I first contacted another HVAC company when my thermostat went blank and my AC stopped working, and their technician seemed more focused on selling expensive repairs than actually fixing the issue. He gave me a confusing explanation, tried to make the repair sound bigger than it was, and offered pricey options with payment plans right away. It felt like a pushy sales pitch. Thankfully, I decided to get a second opinion and called this team. They sent Brendan, who was skilled, straightforward, and honest about what was really going on. Brendan explained the problem clearly, and it turned out to be much less serious—and much less expensive—than what the other company claimed. There were no gimmicks or sales tactics, just a real explanation and fair pricing. If you want trustworthy HVAC service and a fair deal in Denver, this is the team to call.

We recently had two big furnace repair projects done at our home in Denver and couldn’t be happier with the results. The first job was getting a new furnace and water heater installed, and the second was putting in a new central heating system with all the ductwork (we didn’t have central heat before). Herbert and Brendan were the main technicians for both jobs, and they did outstanding work. They arrived on time, clearly explained all our options for things like vent and pipe placement, and made sure to work carefully around the unique features of our older house. Herbert and Brendan kept everything clean, organized, and really paid attention to the small details. We are very pleased with our new heating systems and highly recommend this company for furnace repair and installation in Denver.

allied heating & air conditioning came to our home in denver to repair our heater and make sure everything worked perfectly for the colder months. our technician was matthew. he did a fantastic job with the heater repair and made sure to clean up after himself, so there was no mess left behind. matthew was very professional and walked us through how to use the digital thermostat for our heating system. the service was excellent, and i really appreciate how smooth and easy the whole process was. highly recommend if you need heater repair or maintenance—great company to work with. our home is warm and comfortable again.

After moving into our new home in Denver, we quickly realized our old HVAC system needed some serious help. We soon had to replace our air conditioner, and not too long after, our furnace gave out as well. We did our research and chose Allied Heating & Air Conditioning because their prices were fair, they kept us updated every step of the way, and everyone was friendly and respectful. We were so happy with their AC installation that we called them back to handle the furnace too. A little while later, we started having problems with water collecting in our crawlspace, where the AC and furnace were installed. Whenever we got heavy rain, the units would shut down to protect themselves from water damage. This wasn't an issue with the work or the equipment—it's just that the crawlspace makes things tricky. Throughout this process, the service team was always there to help us figure things out. Brendan, our most recent technician, went above and beyond by coming out on a weekend for an urgent call and then returned a few days later, free of charge, to try moving some HVAC parts around to see if it would help. He was determined, creative, and genuinely cared about fixing the problem. Even though the water issue in our crawlspace is something we need to address separately, we feel confident knowing the AC and furnace are taken care of. I highly recommend using this company for any AC repair or HVAC needs, whether it's a routine job or something unexpected that comes up later on.

I own an older ranch-style home in Denver that originally had all-electric baseboard heating and no central air conditioning. During hot summer days, I used to rely on a window fan at night to pull in cooler air, then kept the windows and curtains closed during the day, hoping to keep the indoor temperature comfortable. After hearing about rebates available for high efficiency evaporative coolers, I decided it was time to upgrade my home’s cooling system. I did some research and found a local HVAC company with great reviews, and contacted them to discuss installation options. Brendan and his team came out and installed a new evaporative cooler for me, running three air ducts to efficiently cool the house. I really liked that the company had their pricing info for different evaporative coolers listed on their website, which made it much easier to plan my budget. The installation took most of the day, but Brendan and the crew worked hard and got everything set up perfectly. The new system has made a huge difference—my home stays cool and comfortable even during the hottest days in Denver, and I don’t have to rely on old fans anymore. Brendan also helped me complete the paperwork for my energy rebate, which I appreciated. I’m very happy with my new evaporative cooler and the service I received. I definitely recommend this company to anyone in Denver looking to upgrade their home’s cooling system.

We had a team come out to install a new gas furnace, air conditioning system, mini splits, and an on-demand gas water heater in our older home, which had never had gas or forced air before. It was a full HVAC system installation, and everything was handled with care and professionalism. The work was done thoroughly, and we are extremely pleased with the results. Winters in Colorado can get pretty cold, so we're excited to see how much our electric bill will drop now that we have a more efficient system. Special thanks to Ross, Matthew, Brendan, and the rest of the crew for making the process smooth and easy.

wow! my husband and i needed heater repair when our old furnace broke down during a cold spell. we got quotes from a few companies for the same kind of heating system, but this team gave us a price that was much lower than the others. what really stood out was their amazing crew. ross, matthew, and brendan were friendly, respectful, and worked really hard to get our new heater installed quickly. even after a long day, they stayed positive and focused until everything was done right. i've lived in my house for many years and can't remember having a better experience with any home service. if you need heater repair or replacement, you should definitely give these folks a call!

I recently had a fantastic experience with a local HVAC team who installed a new split system inverter heat pump in my home. We decided to upgrade from our old oil-burning system in the basement and added a completely new setup, including vents and returns in the attic. This really helped balance out the heating and cooling throughout the house, which used to be a big issue for us. When we first reached out to the company, Herbert came out to give us an estimate. Herbert was extremely thoughtful and truly listened to what we needed for our home comfort. He explained everything clearly and made sure we understood our options, which made us feel confident in moving forward with the project. Although we waited a bit to get scheduled due to the size of the job and equipment availability, it was well worth it. The installation crew, led by Matthew, Brendan, and the rest of the team, was professional, on time, and very respectful of our space—especially since I was working from home during the entire process. They were friendly, easy to communicate with, and made sure to keep everything clean. Matthew paid extra attention to coordinating with our electrician, ensuring all aspects of the job were done right. The whole team worked together seamlessly and made sure we were happy with the results before they left. I couldn’t be happier with the outcome—our home feels comfortable in every room now, and I highly recommend this HVAC company to anyone looking for reliable and professional service in Colorado.

My first experience with this company was after moving to Denver. They have always been my top choice for AC repair and heating service. Every time, the team is friendly and professional. Recently, I woke up to a cold house and called them early in the morning, even before they opened. The staff was very pleasant, and I quickly got a call back from their service team. I explained my situation and busy schedule, and they made it a priority to get my furnace running again before I had to leave for the day. Their fast response and teamwork really made a big difference. I highly recommend their AC repair and heating services, as well as their technicians and office staff. They truly know how to take care of their customers.

Herbert and his team did an excellent job repairing our furnace in Denver. After getting a few different quotes, we found that their service offered a more energy-efficient furnace at a better price, especially with some great incentives for upgrading from an older unit. The new system is very quiet and doesn’t take up much space. Herbert made sure to explain the repair process and all the choices they made, which we really appreciated. The furnace works perfectly for our 850 sq ft home, and I’m very satisfied with the outcome. I would gladly recommend their furnace repair services to anyone.

Allied Heating & Air Conditioning installed a new furnace and central AC system for us, and the whole process went smoothly. The team was friendly and professional, and they honored their original price even when the job turned out to be a bit more involved. Recently, when our AC stopped cooling, Ross came out quickly—just a few hours after we called. He found the problem right away, which turned out to be a clogged air filter that I had forgotten to change. Everything was fixed in no time, and the AC is now working perfectly again. We've had great experiences with their AC repair and installation services and plan to rely on them for any future needs.

I recently had my furnace checked and was told honestly that a new furnace was needed. The technician, Ross, gave me a clear review of my current system and provided a detailed quote for a replacement, including all the possible cost credits and rebates. They set up an installation date and were actually able to come out even earlier than planned when a spot opened up. The final bill matched exactly what I was quoted, with all credits applied as promised. A couple of weeks after the install, I even received an extra $150 credit they found for me. The installer took a bit longer than expected, but it was worth it because he did excellent work and took the time to explain how to use and maintain the new furnace. I really appreciated the thoroughness and honesty. Highly recommend for furnace repair and installation needs.

I can't say enough good things about Allied Heating & Air Conditioning. I needed AC repairs for both units in my Denver duplex, and each time the experience was excellent from start to finish. Herbert did a great job with the estimate, clearly explaining the repair process and helping me understand what would happen next. The technicians who came out were always polite, friendly, and very professional. They really knew what they were doing and got the repairs finished quickly. After the AC work was done, they showed me how to use the new thermostat and made sure I understood how to keep everything running smoothly. This is a fantastic company, and I would recommend their AC repair services to anyone looking for reliable help in Denver.

I highly recommend this company for AC repair and related services. When it was time to upgrade my home's air conditioning system, Herbert and his assistant arrived early in the morning, fully prepared with all the necessary tools, pipes, and equipment. Herbert clearly explained the process of replacing my old unit with a more efficient model, and he made sure I understood what was being done at every step. The installation was almost finished by the end of the first day, with just a little time needed for everything to set properly. Herbert and his assistant made sure to clean up the work area and the entrance before they left, leaving everything neat and tidy. I am very satisfied with their professional work and the improved cooling in my home.
