HVAC reviews in Denver, Colorado

I was so pleasantly surprised by how amazing my experience was with UniColorado. Thorough, honest, and personable, this company gets it. They’ve earned my business for as long as I live in Denver, and I’d like to thank them again for their great work servicing our outdoor A/C units.

I cannot say enough good about this company and everyone who works here. After a traumatic experience with another company I reached out to UniColorado (at 9pm!) and not only did they answer the call, they calmed my fears tremendously. Everything after that with them was a pleasure. They gave us a much more reasonable price, stuck to every timeline and did a fantastic job. Passed city inspection in mere minutes. I have absolute trust in this company and feel they're one of the best in the business.

Brian arrived early today to look at a furnace problem I had with one of my furnaces. Turns out it was in the thermostat, which he replaced. He noticed that the furnace needed a tune-up. I asked him to look at the second furnace also, since I had them installed at the same time. It also needed a tune-up.

He was pleasant and respectful of my home. He explained everything about the problems and quickly and efficiently completed the tasks. I took his card because I want to remember to call UniColorado again for all of my furnace needs.

Free estimate and they came in with best pricing for a new dual fuel system as we got a cold weather heat pump and high efficiency furnace. Work was completed in one full day. Our system was failing so they had a cancellation and got us in early.

Afshin and Aydin were great to work with! The whole process from solution design through installation went smoothly, all at a fair price. They were always responsive and the job finished on time. Couldn't recommend more.

UniColorado recently handled a Mitsubishi heat pump / mini split installation for my property. Top notch outfit from start to finish. Aydin and Afshin were very knowledgeable and always helpful / responsive for questions throughout the entire process from initial outreach / installation / paperwork / etc. The installation crew / electrical subs were likewise communicative, clean, and courteous. Great work, great team - thanks all.

UniColorado installed a Mitsubishi Mini split system in my house yesterday. They did it in one day, with 95 degree outdoor temperatures. The heat didn't slow down with two technicians, or the contracted electrician. They started at 9 and we had AC temps of 68 degrees in the house by nighttime. What a treat to sleep now in a cool room when it is so hot outdoors. The Mitsubishi products they used, and the installation made for a wonderful addition to our 70 yr old house. We couldn't be happier with the final results, and the continuous customer service and responsiveness they provide. They were great to work with and I will continue to use them for other services.

Our experience with UniColorado has been wonderful. They have helped us through the process of installing a new heat pump and energy efficient furnace, as well as claiming the state heat pump tax credit and the City and County of Denver incentives. They are responsive, courteous, and very friendly to work with, and we cannot recommend them enough!

Great experience purchasing a heat pump through UniColorado. Very knowledgeable about heat pumps and what’s needed to ensure comfort in a Colorado winter. I got multiple estimates and their price was the best. The installation was smooth and easy. And, they submitted rebates and supported tax filing. Can’t praise them enough!

If you’re looking for honesty and integrity, check out Uni Colorado.

I found Uni Colorado when I was getting estimates for a mini-split install in our living room. Uni was the cheaper, by at least $1500, than two other estimates. Plus, the tech really knew about rebates and applied them for us (except for federal tax rebate). Ayden was super patient with our questions and has checked in to be sure all is well.

Not long after, our central HVAC unit failed and I asked Uni to check it out.

Other companies might have suggested a new unit, but Uni was able to fix the problem with the compressor for a few hundred dollars.

As someone who is very concerned about the climate crisis, I appreciate Uni’s commitment to reducing their carbon footprint. They are replacing their work trucks with Ford EV150s. And they really know heat pumps and use Mitsubishi products, which get top ratings.

Finally, the mini-split install went smoothly. They were able to install without tearing up our 80 year old plaster walls, and cleanup was thorough.

I highly recommend Uni Colorado.

Our home has 2 furnaces and 2 air conditioning units. When our 18-year-old, 80% efficient furnace in our basement died, UniColorado Heating & Cooling was the last of 4 HVAC companies I interviewed to replace it. UniColorado installed a 97% efficient furnace for about 60% less than what one company would have charged for an 80% efficient furnace. I wish I had used UniColorado when we installed a heat pump water heater last year.

Exceptional all around. Everyone on the team is knowledgable. I felt empowered to make good choices for our systems. The installers treated our home with the utmost respect. Everyone was friendly and polite. All my requests were taken seriously. The work was expertly performed with precision detailing. I can’t recommend UniColorado highly enough!

The entire UniCo team has been great, and much better experience than any other contractor I was getting new furnace quotes from. They are more knowledgeable and straightforward than any other shop out there.

The technicians put in a long day but were able to get it done, with solid workmanship, too!

If we move I’m definitely contracting them again to get a new system. They keep up with industry changes like heat pumps and are a pleasure to work with.

We had a great experience with UniColorado. We replaced our furnace and AC with a heat pump with gas furnace backup. They were very knowledgeable about all aspects of the systems and available rebates and tax incentives. We’re very pleased.

I had a wonderful experience with UniColorado. They were very prompt in answering my questions, and even got into the details with me on AHRI ratings, heat pump set ups, efficiencies, and all the nerdy HVAC stuff. As far as installation goes, it was smooth, fast, and the team was very good at communicating with me the whole time. Aydin was super helpful throughout the whole process, and I am extremely happy with my new heat pump set up.

UniColorado was the most amazing contracted company I've ever worked with. They did a big job at my house including a multi zone mini split/heat pump system, a panel upgrade, and an EV charger. Not only were they the most up front, transparent, and thorough, but also the most affordable. I got over 5 quotes and UniCo was the best in every category, including innovation. Some contractors wanted to put the panel in the alley side of my house which was not acceptable for me and UniCo came up with a better solution. They also handled all the credits and rebates through the city and state and made the process seamless. Also, the electric company they work with were incredible. They made sure everything was good for inspection and were timely and efficient. I think Colorado electric, but not positive. In any case shout out to Dan and his crew. All the techs and install crew were super friendly, professional, polite, and worked hard and quickly. Can't say enough good things about this company. Don't even bother with quotes from others, Aydin and the guys at UniCo will beat anyone else.

This company was fantastic to work with from start to finish! I made the jump to have a heat pump installed and looked at a few different contractors. UniColorado was always the quickest to respond, took the time to thoroughly answer all of my questions, and listened to all of my considerations and wants when they designed my heating and cooling solution - and the energy credit process, and city inspection post-install, was incredibly smooth and they handled all of it.

They made the process easy, efficient, and painless! Their techs are hard working and got the job done in two days and spent a good amount of time walking me through the system post-install so I knew how to use the new heat pump set up.

My only regret is not working with them sooner to get AC installed before the brutal Denver summers!

UniColorado installed two ducted heat pumps and backup furnaces in our house recently. They were very communicative throughout the whole process. I especially appreciated that Aydin came up with four different options for our system, listing out the pros, cons, and tradeoffs of each option. He and Afshin also did a great job of answering any questions and explaining how the technology and install worked. Their pricing was also very competitive and they walked us through the different options for heat pump rebates in Denver.

They were also able to schedule the installation quickly and the installation team did a great job, were courteous, and cleaned up afterwards. I'd definitely recommend them and we'll definitely work with them if we have future HVAC needs!

We were very pleased with the installation of our mini split system. It was very easy to schedule service with UniColorado and they always provided updates on arrival times and showed up when scheduled. Work was done professionally, very knowledgeable regarding their products, and were very responsive to all of my questions/concerns. Pricing was also very competitive. Afshin the Service Manager was very personable and easy to work with, I would highly recommend this company.

Aydin and team were absolutely fantastic. The install was efficient and smooth. By far the best value that we received quotes for.

Honest and trustworthy. I had a bad AC and had four companies come to offer solutions. In the end, UniColorado had the best price, equipment and knowledge to get the job done right. I ended up going with a new Heat Pump system because of all the rebates, and the system works great, even when it is 100 degrees outside. The installation crew was great and made sure everything was pristine before they left. Price was important, but above all I trusted their honesty and knowledge more than anything else.
