My husband and I have used MileHi HVAC for our properties for the past 2 years. We have found them to be responsive, easy to work with and very competitive in their pricing. They will remain our “go to” HVAC providers


The air conditioning went out in our rental last Thursday when it was 95 degrees out. MileHi HVAC responded within one hour. Fixed the air conditioning and did an inspection of the entire unit. Technician was very polite, courteous, and professional.

FANTASTIC. Highly recommend! We had a slight emergency and contacted a few companies. This was the first one where I received a call immediately asking how they could help me despite the fact I had called past their business hours.
