I am a Real Estate Agent in the Denver Metro Area. I have used Dave from Heatmiser since 2005. I personally have several rental properties and have clients call for a HVAC referral all the time. Heatmiser is the only company I refer with confidence. Heatmiser does amazing work, always comes through when it's really needed and always has the best value. I don't have any other HVAC company in my phone. I highly recommend Heatmiser all your HVAC needs!

We have used Dave at Heatmiser on two different occasions over the past 3 years and got amazing service both times. Most recently we needed our furnace cleaned and certified. Their prices are very reasonable and they are very knowledgeable, professional, and most importantly, personable! Highly recommended to anybody who needs any sort of HVAC work completed!
