HVAC reviews in Denver, Colorado

This past Sunday, when it was freezing outside in Denver, our heater suddenly stopped working. Thankfully, I found Allied Heating & Air Conditioning online and saw they offer Sunday service. I talked with Herbert, who said he could come out as soon as possible. He arrived quickly, figured out the problem, and had our heat back on in no time. He did a great job, kept everything clean, and made sure the work was done right. Later that night, he even sent a follow-up text to make sure our heater was still running smoothly. I highly recommend them for any heater repair or furnace service.

ross and the team are professional and really know their stuff when it comes to furnace repair. they always remind us of appointments with handy text messages, which is very helpful. they do a fantastic job when there's a furnace emergency. we've been happy customers for over 20 years and are looking forward to many more. herbert has been taking care of our furnace and heating system in denver for a long time. he is quick, professional, and always gets the job done right. best service we've had when our furnace needed repair during cold weather.

I had a fantastic experience with Allied Heating & Air Conditioning when my furnace broke down right before Christmas. They were quick to respond and managed to install a new furnace the very next day, working late into the night until I finally had heat! Without their prompt service, I might have faced serious issues with frozen pipes in my old 1890's home, where everything is a bit off-kilter. The team handled the installation with ease, connecting the new furnace to the existing ductwork without any major problems. Ross and the team were incredibly friendly and great with my pets and kids. It all felt almost too good to be true, especially when I saw the final price, which was much lower than I had initially expected and definitely more affordable than other companies in the Denver area. When my 20+ year-old air conditioner stopped working just as the heat wave hit, they came to my rescue again. They helped me upgrade to a new system after realizing the old one couldn't be fixed. The new air conditioner was installed quickly and is way more efficient than the old one. The quality of service was just as outstanding this time as it was back in 2010! I highly recommend them for any furnace or air conditioning needs!

I’ve been a satisfied and repeat customer of Brendan for a long time. We first called Brendan to remove and replace an old furnace from our 1918 Craftsman style home in Denver during the winter, and we were really pleased with how it went. Later on, after moving, we needed to swap out a very old industrial furnace at our new place, and we didn’t hesitate to call Brendan again. We were just as happy with the results as before. Brendan really knows HVAC systems and is happy to share advice over the phone, so sometimes you don’t even need a service visit right away. He recently helped me over the phone to change out our thermostat, which saved me both money and hassle. I would recommend Brendan to anyone needing heating or air conditioning help—he’s definitely my top choice for HVAC services.

What an outstanding heater repair service! Prompt, professional, and quick to respond. Our heater stopped working one morning, so I called and spoke with Ross, who said he would be out in about an hour. I received text updates letting me know when he was on his way and when he would arrive, keeping me informed each step of the process. Ross did a fantastic job! I was a bit embarrassed about how dirty our heater was, but Ross took it apart and gave it a really thorough cleaning. He also told me about their maintenance program for both summer and winter, and I signed up right away. I’m very grateful to have found such a reliable heater repair service.

i had allied heating & air conditioning come out to repair our heater and check on the heating system. brendan was clean, showed a lot of respect for our home, and did top quality work. he answered all my questions, and i had plenty. the office responded quickly whenever i called. the prices were very fair and they explained all the costs upfront. they even handled some custom heater work for us. we're really happy with how much more comfortable our home feels now.

All my interactions with the staff were professional, friendly, and they always arrived on schedule. They returned my phone calls quickly. The estimator, Matthew, really knew his stuff about furnace repair and explained everything clearly. The company is a leader in efficient furnace systems and upgrades. They are well-known and respected for their expertise in the furnace repair and home heating industry.

I got home late after work and noticed my AC unit on the top floor wasn’t working. I called this company and spoke with Herbert, even though it was already 10pm. I was really surprised someone answered the phone that late. After I explained the problem, Herbert said he could be at my place in Denver in about 15 minutes. Just like he promised, he showed up right on time and quickly got to work. Herbert was very professional and took the time to explain exactly what was wrong with my AC. He mentioned that the unit had never been serviced since we moved into our house, and assured me he would get everything running smoothly again. He finished up around midnight, and I was so thankful that he was willing to help out so late. I highly recommend this company and Herbert for anyone needing AC repair in Denver!

Here’s a rewritten version of your review, following all requirements: I want to share my great experience with Allied Heating & Air Conditioning. About a week ago, our downstairs AC started making a loud squealing noise. We called our regular technician, who told us to stop using it and promised to fix it soon. Then, a few days later, the upstairs AC stopped blowing cold air. Luckily, the weather cooled off a bit, which helped us get through it. On Monday, since we couldn’t reach our regular tech, I contacted Brendan after seeing good reviews about the company. The response was super quick and professional. Brendan and another technician showed up fast and, in less than an hour, took out the blower motor from our downstairs AC and replaced the capacitor for the upstairs unit. Just like that, we had cold air again! A couple of days later, two more team members came by and installed the new blower motor for the downstairs AC. Everything is now working perfectly, and our home is cool and comfortable. I am really impressed with the quality of work and friendly service. If you need any AC repair or service, I highly recommend this company!

Here’s your rewritten review with all your requirements carefully followed: --- I want to thank Allied Heating & Air Conditioning for their outstanding teamwork and service during my recent AC replacement in Denver. Matthew, the comfort specialist, along with Herbert and Ross, the installers, did an exceptional job removing and replacing my old HVAC system. They also installed a new air purification system, which made a noticeable difference in our home’s air quality. The team worked together really well and used their skills to solve some tricky problems in the attic and laundry room. They were all professional, organized, and made sure the job was done right from start to finish. Customer service was excellent—everyone was friendly and answered all my questions. I also had Aeroseal installed in my ductwork, and the difference is impressive. There’s much less dust in the house, and the before-and-after computer readout showed a huge improvement. The combination of the new AC, air purifier, and sealed ducts has made our home much more comfortable, especially during Denver’s hot summers. I highly recommend this company for both residential and commercial AC repair and installation. They’re always on time, knowledgeable, and truly care about their customers.

My AC stopped working on a Sunday afternoon, so I called Allied Heating & Air Conditioning. I spoke with Matthew, who said someone could come by between 9 and 11 am the next day. The technicians, Herbert and Ross, arrived around 9:30 am. They were both very professional and clearly knew what they were doing. They quickly found the problem with my AC and fixed it, and also gave me tips on how to keep my system running smoothly in the future. They did maintenance on both my outside unit and the one in the attic. Everything was done efficiently and on time. When I asked about future maintenance, they even checked with their manager and gave me a discount on the total cost. I would definitely use their AC repair services again. The technicians are knowledgeable and friendly.

Excellent heater repair service! I will definitely keep using them. Ross and Matthew arrived right on time and were both very friendly and professional. Our heater's fan was running nonstop, but it turned out to be a simple setting issue with our new thermostat. Ross patiently showed me how to adjust the settings and explained everything, which made me feel comfortable and supported. Before leaving, they made sure to check both the indoor and outdoor units. The outdoor unit was very dirty and could have affected the heater’s efficiency, so they cleaned it up thoroughly. I really appreciated their attention to detail, professionalism, and the care they took to make sure our heater would run smoothly all season.

After having trouble with my furnace several times, Ross came out on a service call. he really knew what he was doing with these kinds of heating systems. Ross listened to me explain all the problems i had with the furnace, talked with the manufacturer, checked everything carefully, and ran some tests. he found a few things with the setup and venting that weren't right for a modern furnace. After we talked it over, we agreed the best move was to replace the old furnace with a new one and update the venting and connections at the same time. it's not a cheap fix, but Allied Heating & Air Conditioning gave me a fair price and good payment options. We got all the details sorted out quickly so parts could be ordered and installation could happen soon. Matthew and Brendan came by for the installation as planned and finished it the next day, just like they promised. After it was all set up, a technician came back out right away to make a small adjustment at no extra charge. now the house is warm and the heat works great. i will definitely call them again if i need any more furnace help.

I have been really impressed with Allied Heating & Air Conditioning. Brendan, who came out to look at our heater, was not pushy at all. He knew a lot about heater repair and explained everything in a simple way. Brendan even came out on short notice and was very considerate of our family's needs. The installation crew—Herbert, Ross, and another technician—were all very skilled, kept everything tidy, and answered all our questions about the furnace. Brendan has always responded quickly whenever I had questions. The company also called me to help process the energy rebate, so I never had to check in or follow up myself. I spent a lot of time looking into different heater repair companies and brands, and I found that as long as the system is installed right, most are pretty similar. This company gave me the best price and clearly had a lot of experience with heater repairs.

I had an issue with my air conditioning unit not working properly at my home in Denver, so I called for AC repair service.

After moving into our new home, we didn’t know who to call when our heater started acting up. Luckily, we found Matthew’s card on the furnace, so we reached out for help. He responded quickly, figured out that the thermostat was faulty, and replaced it right away. Matthew took the time to explain how the new thermostat worked and gave us helpful tips about regular heater maintenance. We feel confident that Allied Heating & Air Conditioning will handle all our heating needs from now on.

Here’s the revised review, following all your requirements: --- I recently had a maintenance visit for my heater, and overall, I’m happy with the experience. My heater needed some repairs, and Brendan came out to take a look. He was very thorough and explained everything about the heater repair process to me. During the installation, they adjusted the placement of the unit and the gas outlet, which meant the AC piping had to be changed. Even though there was an extra charge to fix this, Brendan made sure everything was done safely and up to code. A part for my heater needed to be replaced, and while it took a little while to arrive, the team kept me updated the whole time. Brendan also took the time to check for any leaks and made sure all the connections in the garage were secure. I felt confident that my heater would work well, especially with the cold Colorado winters. The customer service team was friendly and quick to respond to my questions. They made sure my concerns were addressed and followed up to confirm that my water heater was running smoothly after the repairs. I appreciate their attention to detail and willingness to go the extra mile. I would definitely recommend this company to anyone needing heater repair or HVAC maintenance. They’re reliable, professional, and make sure your home stays warm when it matters most.

Brendan called in the morning to confirm the scheduled heater repair appointment at our home in Denver. He arrived soon after and got right to work on the maintenance service. Brendan was very respectful, always taking off his shoes before coming inside to keep our place clean. He did a detailed cleaning of the heater units outside and checked everything to make sure the system was running properly. The whole job was finished quickly and efficiently. Outstanding service!

I highly recommend Allied Heating & Air Conditioning for anyone needing AC repair. I often have to trust service companies to take care of my place when I can’t be there in person, and it’s hard to find dependable help. When my heat pump stopped working, Herbert and the team responded quickly and got everything running smoothly again. They handled everything on time and made sure all my AC repair needs were met without any hassle. It’s rare these days to find such reliable service, especially when you need fast help with air conditioning. You can definitely count on them!

When our air conditioner stopped working late last summer, I looked for a reliable AC repair company. Brendan got in touch with me quickly, listened to my concerns, and clearly explained all my options for fixing or replacing the unit. He answered every question I had and made sure I understood the process. Once we decided to install a new AC and furnace, they scheduled us right away. The team of three technicians arrived on time and worked efficiently and respectfully. In just four hours, they removed the old system and installed the new equipment. After finishing, they took the time to explain how everything worked and left the place spotless—you couldn’t even tell any work had been done. The service was excellent, and I was really impressed with how thoroughly everything was explained. I’m very happy with the results and would definitely recommend this company to anyone in need of AC repair or installation. Everyone was professional and easy to work with.
