Testimonials
Colorado Bear HVAC is truly the best contractors I have experienced since I moved into my house 30 years ago. I have been dealing with Joe and his crew for over 11 years now. They are a trustworthy, respectful, experienced crew who works with you and gives you a fair value. They just completed a big job replacing my A/C, gas furnace and condenser. They did an excellent job, no short cuts, made sure everything was functional, and cleaned up the area nicely before they left. No pressure to perform unnecessary service. You know when the job is done, you have received top notch professional service at a fair price.
I used Colorado Bear Heating and Air to replace two furnaces in my home. Nate was exceptional to work with. His team did a great job educating me along the way. He provided competitive pricing with 10 year warranties. They installed quickly and were just super great to work with. I’d highly recommend them.
Nate and Sam have been great to work with getting my home humidifier installed in a difficult space in my 1940s house. Their prices were very fair and I would heartily recommend Colorado Bear to anyone looking for a solid HVAC company.

Colorado Bear Heating & Air saved the day! This morning my family and I woke up to frigid outside temperatures(1 degree F)…and no heat! Nate was great over the phone to help me check our furnace, then he sent Sam over to help get us back to warmer temps. They were so quick and helpful. Fortunately I did not have to keep my toddlers inside the house wearing snow suits all day. We are warm now, and so thankful!
