Shawn and his team are always amazing to work with and have very reasonable rates for their services. They recently replaced our entire HVAC system, rebuilt duct work, and helped us resolve an issue with a bad thermostat. His team is always on time and get right to work. I will always recommend Miller Cooling & Heating to anyone looking for a good HVAC company.

I've tried the other HVAC companies and the quality of service as well as the fair pricing from Miller is the best.. They service all 4 of our homes and are always there in an emergency and my tenants love the service and respect for their privacy. Always happy to refer Miller's Cooling and Heating to friends, family and neighbors and every time I get thanked and rave reviews.

They have always been there when I needed them. Shawn and his employees put in a new unit approximately nine years ago and did a great job. He has continued to service my unit ever since. I have had a couple of minor issues in the last nine years and he was always prompt and fixed the issues quickly.I will use Miller Cooling and Heating for all my HVAC needs.
