HVAC reviews in Westminster, Colorado

Daniel and his team were efficient and professional installing a heat pump water heater for us, all at a competitive price. They had clear experience and expertise with the equipment that other contractors we spoke to were lacking. Would highly recommend this team for any job, but particularly those involving heat pumps or other emerging technologies.

I'm a repeat customer. Originally, I had a Mitsubishi Cold-Climate Heatpump installed September of 2024. The crew, particularly the owner Daniel and Anthony, were great. Professional, punctual, and friendly. The install was later inspected by a 3rd party by Xcel: visually they were impressed by the install and the cooling performance was one of the best they've measured. I'm mostly through my second winter with it and happy with it.

Late Spring of 2025, I had them install Heatpump Water Heater. Installation went smoothly, but there were a few hiccups with due to limited space and tricky ventilation. Those were addressed. The initial unit had to warrantied out, but at no fault of the installer.

Overall a great experience and I'd recommend them!

The crew did a fantastic job. I do testing and install verifications on MEP systems for work so I was extra nit picky - but they addressed all of my concerns and accommodated the particular duct design I wanted for the heat pump water heater. It’s operating perfectly. It’s also super quiet and there are no issues with cold air getting dumped into the living space, both of which were major concerns for me. Highly recommend!

We had Colorado Eco-Mechanical do a two zone cold weather ductless heat pump (mini split) system as well as a heat pump water heater. They did a great job of a clean install (look at the beautiful copper piping on the water heater!) and everyone was extremely friendly and professional. Daniel was also extremely helpful in navigating Xcel Energy's rebates which made improving our comfort an affordable option!

Excellent service all around on time, thorough, and very neat work. The installation went smoothly, and the new heating and cooling system works beautifully. Friendly staff made it even better.

We're extremely happy with our new heating and air system. The installation team was courteous and efficient, everything was completed with great attention to detail, and the pricing was clear with no surprises.

We used Ascent HVAC for maintenance at our house in Federal Heights. The tech was friendly and made sure everything was running properly before leaving.

We had a wonderful experience. Couple small issues came up and we're promptly resolved. Crew was very professional. Floors look spectacular!!

Fast and friendly really knowledgeable. Would definitely recommend them if you need service

Since it will not allow me to respond to your response. I never once stated I done business with your company. I stated the customer service when speaking on the phone. I would not do business or recommend this company due to the lack customer service as I stated before.
Please re-read my initial review below
Thank you

Michael has one of the worse customer service I have experienced. He is very rude and rushes to get off the phone without letting you speak.

Had a great experience with home repair. Very polite, professional and clean. Did a great job and was very accommodating when I ask to for help with an additional project. I felt I got excellent service for a very reasonable price.
