HVAC reviews in Denver, Colorado

Caleb and Richard came out early in the morning after I called in the middle of the night when my AC unit stopped working. They showed up on time and clearly explained what they were doing every step of the way. Within about 15 minutes, they figured out what was wrong and let me know the best ways to fix it. They offered several repair options and made sure I didn’t feel pressured into anything. Caleb and Richard explained what each option included and gave their honest recommendations. Setting up the AC repair was quick and easy, and both of them were friendly and really knew their stuff. I would definitely recommend them to anyone in Denver needing AC repair. They made the whole process simple and stress-free!

last friday evening, my furnace suddenly quit working just as the cold was coming in here in denver. i called unified heating & air conditioning, and wesley showed up about an hour later to check everything out. early the next morning, he gave me a few different repair options, answered all my questions, and explained the costs clearly. by monday at 9am, luke arrived and worked hard for several hours—by the afternoon, my furnace was running warm and strong again! he was very patient with all my questions while he worked, which i really appreciated. the quick response and professional attitude made the whole process easy and stress-free. the service, prices, and friendly team can’t be beat. i’m so glad there are still companies like this out there!

From my very first phone call to the final inspection, my experience with this HVAC company was outstanding. When our air conditioner broke down during a week of extremely hot weather, I reached out as a first-time customer. I was immediately impressed that a real person answered the phone, which made a stressful situation much easier to handle. The office staff was friendly and quickly arranged for a technician to come out that same morning. Luke, the technician, was very thorough in his troubleshooting, carefully checking everything from minor issues to more serious problems. Since our HVAC system was nearly two decades old, it wasn’t a surprise when we learned we needed a full replacement. Luke clearly explained every step he took and what he found, which helped us understand our options. Within an hour, another team member arrived to take measurements and provide a quote. We ended up deciding to replace our entire system, including the AC, furnace, and water heater, and were pleasantly surprised at how affordable it was. Luke patiently walked us through all the available choices and financing plans, making sure we never felt pressured. Thanks to their flexible financing, we were able to set up a payment plan that fit our budget, with no penalties for early payoff. The installation team arrived promptly on Monday and completed the work efficiently and professionally. They even poured a new concrete pad for the AC unit at no extra charge. By early afternoon, the new system was up and running, and the crew left our home spotless—no sign of debris or the old equipment. Before they left, they gave us a detailed walkthrough of our new setup. As part of the package, we received a complimentary duct cleaning and CO2 detectors for both levels of our home. We also love the new eco-friendly thermostat, which is easy to use and helps us save money by syncing with our local energy provider. Final inspections went smoothly, and to our surprise, the team presented us with a thoughtful gift basket along with our paperwork. Everyone involved was knowledgeable, courteous, and truly went above and beyond. I highly recommend this company to anyone needing HVAC services—they’ve definitely earned my loyalty!

Unified Heating & Air Conditioning provided excellent furnace repair and installation service for my home. Recently, Caleb came out to replace my old furnace that had stopped working. He did a fantastic job and made sure everything was properly set up and running smoothly. I was especially pleased that he took the time to fix some taping issues on the ductwork from a previous visit, making sure the airflow was properly sealed and efficient. The whole process was handled professionally, and the technician made sure to clean up after the installation was done. The new furnace works great and keeps the house warm, which is important during our cold Colorado winters. I highly recommend this company for anyone needing furnace repair or installation. Very satisfied with their work!

we have used this furnace repair company in denver several times. most recently, they replaced a furnace and later installed an air conditioning unit at one of my properties. when i needed the furnace swapped out right away during a really cold snap, they got out there fast and had the heat running in no time. as i asked, they waited until spring to put in the a/c. hayden has also helped with other furnace and ac work for me, and each time the job was done really well. the team is always on time, professional, polite, and makes sure to clean up after themselves. every service has been a great value, and i always tell others to use them for furnace repairs.

caleb with the team recently handled a heater installation at my house in denver. caleb was very detail-oriented, easy to reach, and super honest throughout the whole process. for instance, when he saw that the new furnace had a small scratch on the back (which wouldn't show after installation), he talked to the supplier to get a discount and passed those savings on to me. caleb also made sure to give me a really competitive price for the heater repair and installation work. i highly recommend caleb to anyone in denver needing heater repair or furnace service, especially with how cold it gets here.

richard came out to check my furnace when it stopped working, and explained clearly that it was time for a replacement. he let me know all my options and helped me pick what worked best for my home. hayden and caleb showed up right on time the next day to handle the installation, and they did a really careful and professional job setting up the new furnace and thermostat. the office even reached out to help me with a rebate for the new thermostat, which was a nice surprise. overall, everyone i talked to was friendly and helpful, and the whole process was easy from start to finish. i've trusted this company for furnace repairs and service for years and have always been happy with the work. highly recommend for anyone needing reliable furnace repair or installation.

I had a fantastic experience with this HVAC company in Denver. My wife and I came home late at night to discover our furnace had stopped working while we were away. Early the next morning, I called for help, and within an hour, Richard from their team arrived to check out our system. After inspecting everything, Richard explained that our old furnace needed to be replaced. Amazingly, they were able to install a brand new furnace that very same day! Every person we spoke with was friendly and went out of their way to make sure we were comfortable throughout the process. We’ll definitely use them again for any future heating and cooling services.

What can I say? During a cold winter in Denver, our 30-year-old boiler started acting up and one of our heating zones stopped working. We really needed help fast since it was getting pretty chilly inside. I called for heater repair and they were able to schedule us right away. Caleb showed up on time, quickly figured out the problem, and fixed it almost just as fast. Thanks to Caleb, our heat was back on and my family could finally ditch the extra blankets. We’re really happy with the service. Caleb was professional, friendly, and clearly knew his stuff. He explained the whole repair process to me and even gave me some tips on how to spot common heater problems myself, so I don’t have to worry about every little thing. Now I feel a lot more confident about knowing when to call for help and what’s normal for our heating system. Overall, the service was excellent and I wouldn't hesitate to call again in the future.

During one of Denver’s hottest summer weeks, my air conditioning stopped working. I reached out to a local HVAC company for repairs, and their technician said my unit needed new coils and a condenser, with a repair quote of $4,000—even though the parts were still under warranty. Wanting to be sure, I got a second opinion. The next technician, Jesse, came out, took a thorough look, and quickly discovered that the real issue was the thermal expansion valve. Jesse got my HVAC system running smoothly again in less than two days, and the total cost was only $480. The service was fast, professional, and fairly priced. I’m really happy with how quickly and efficiently the problem was fixed, and I’ll definitely call them again for any HVAC needs in Denver.

Our experience with this HVAC company in Denver was outstanding from start to finish. We got several quotes, including one from a popular membership club, and this company’s price matched the best offer, but they provided even better equipment for our heating and cooling needs. The installation process went smoothly. Caleb, Hayden, and Jesse were all friendly, professional, and worked efficiently. We had a big job—replacing our old furnace and AC units that were over 30 years old, plus installing new ductwork for the dryer. At first, the work area looked busy, but by the end of the day, everything was neat and looked better than before. They also took the time to explain our new HVAC system and showed us how to keep it running well. We couldn’t be happier with the service and highly recommend them!

Absolutely outstanding AC repair service! After dealing with cooling problems in our Denver home, I reached out to Unified Heating & Air Conditioning. Jesse arrived right on schedule, even though it was late on a Friday afternoon before a holiday. Within minutes, Jesse figured out exactly what was wrong with our air conditioning and didn’t leave until everything was running perfectly again. The repair was affordable, costing less than $200, which was a big relief after another company had suggested a much more expensive fix. Previously, a different HVAC technician from another company spent hours looking at our system and said we might need to replace the coils, which would have cost thousands. They even tried to push us toward buying a whole new AC unit. On top of that, their service fee jumped just because we wanted a second opinion. I am so glad we called Unified Heating & Air Conditioning instead. The technician provided a simple, honest solution and got our home cool again quickly. We were so grateful for the honest work and fair pricing. I highly recommend this company for anyone needing AC repair in Denver!

i usually don’t write reviews, but i really want to share how great my furnace repair experience was with Unified Heating & Air Conditioning. my old house needed a new furnace, and i was worried because it’s over 100 years old and has a lot of unique features that make installation tricky. luke led the team, and he did an amazing job working around the layout so everything fit perfectly and looked neat. he spent extra time measuring each spot, talking with me about where things would work and look best, and explained every step as they went along, even showing me how to keep the outside pipes and wires less noticeable. he even shared some simple tips on painting the parts so they’d blend in better. it was a busy season for furnace repairs, but the team made sure to fit us in and kept our original appointment. everyone was polite, helpful, and really seemed to care about our comfort. from the first phone call all the way to the final walk-through, i felt respected and well taken care of. when the furnace was installed, luke took his time to explain how to use and maintain it, including little things like checking the filters and keeping the area clear so nothing gets damaged. he also noticed we have allergies and suggested an air filter that i never would have thought of, which has made a big difference. even though it was late and he had a long drive, he stayed to make sure everything was clean and that i understood how to use the new system. his team, wesley and caleb, were just as friendly and professional, and they even worked around my remote work schedule so the noise wouldn’t bother my meetings. honestly, if i could give them 6 stars, i would. i’m very happy with how everything turned out and feel confident going into winter knowing our furnace is working perfectly.

My heater was running all the time but my condo in Denver just wasn’t getting warm. Wesley from Unified Heating & Air Conditioning came out to check my system. He was friendly, professional, and kept me informed about everything he was looking at. He discovered my heater was low on refrigerant and found a leak in a coil that needed to be replaced. Since my units were older and the part would take several weeks to arrive, I decided it was best to upgrade the whole heating system. Richard took the time to walk me through all my options and gave me three different choices with clear pricing. He made sure to keep in touch and let me know when my new equipment was ready for installation. Jesse came by to install the new heater and air handler. He was easy to talk to, did a great job, showed me how to use my new system, and made sure everything was cleaned up before he left. The whole team was helpful, quick to respond, and very respectful during the process. I’m really happy with the service I received and would recommend them to anyone needing heater repair in Denver.

Unified Heating & Air Conditioning provided excellent heater repair service from start to finish. Their whole team was professional and really seemed to care about my comfort at home. A few years ago, I decided to get a new heat pump system, and it has truly been a great choice for my heating needs. Even though the upfront cost was a bit higher, I’ve seen great savings on my heating bills since then. Caleb, who helped me through the process, explained all the different heater options and operating costs in a clear, friendly way without pushing me to make a decision. I am very satisfied with my heat pump and the whole experience with this company!

We've had this team help us with several AC and heating repairs at our home in Denver. When our heat stopped working last winter, they showed up quickly and got everything running again in no time. Later on, when we decided to replace our old AC unit since it was over 20 years old and had needed repairs more than once, Mitchell explained all our options clearly and made sure we understood the best choices for our house. On installation day, the crew was professional, efficient, and kept us updated throughout the process. They finished the job faster than we expected, and Mitchell even gave us a call afterward to make sure we were happy with everything. I highly recommend them for any AC repair or heating services!

Unified Heating & Air Conditioning came through for us again with our AC repair. After switching our maintenance plan to them, we noticed a real difference in how our system was serviced. We weren’t satisfied with our last HVAC company, even though they installed our heat pump, so we asked Unified for a second opinion. Their technician, Jesse, gave us an honest and clear assessment of our air conditioning system and shared helpful advice on how to keep it running smoothly. That’s when we decided to join their maintenance plan. A few months later, we turned on the AC for the first time this season and it wasn’t cooling properly. We called and Jesse arrived promptly, spending plenty of time checking everything and explaining that the previous install had a few issues. He pointed out what needed to be addressed without saying anything negative about the other company. Because we had their Comfort Club agreement, this visit didn’t cost us anything. We contacted the original installer with the findings, and they fixed the issues under warranty. Throughout the process, Jesse was knowledgeable, explained everything, wore shoe covers inside, and made sure to keep everything clean—even the ceiling access panel. The office staff was also great and very friendly, sending helpful appointment reminders and even a bio about the technician coming to our home. We’re really happy with the service we received and recommend calling them for any air conditioning or heating repairs. You won’t be disappointed!

We recently had our heater repaired and upgraded, and we are extremely pleased with the whole experience. From the very first quote and our meeting with the technician (Wesley), to the installation day when the team handled everything—including some duct work adjustments—the process was smooth. A maintenance specialist (Richard) even came by a couple of weeks later to check and fine-tune our thermostat, which was a courtesy follow-up from the company. Wesley was always helpful and patient with our questions, and every team member we met was professional, knowledgeable, and respectful. We feel confident knowing we can count on this company for future heater maintenance and any unexpected repairs that might come up, especially with how cold it can get in Colorado. Overall, the service was excellent and we highly recommend them for heater repair and maintenance.

We recently had a Mitsubishi multizone heat pump system installed in our home. From our first call all the way through to the installation, the whole experience was smooth and stress-free. Everyone we spoke to from the company was professional, helpful, and clearly knew a lot about HVAC systems. Hayden in sales answered all our questions and made sure we understood our options, and the installation crew—Caleb, Luke, and the rest of the team—did a great job setting everything up and making sure it worked just right. Even the electrician who helped with the install was friendly and skilled. Now our home stays comfortable no matter the weather, and we’re really pleased with how everything turned out!

$200 to simply check the AC unit (not applied to any repair work) is well above market.

Hired this company to replace my heating and air conditioning system. They did an amazing job, and I would definitely recommend them to anyone!
