From a Single Truck to Longmont's Most Trusted HVAC Name
Summit Heating & Air was founded in 2008 by Mike and Jennifer Hartley with one simple mission: treat every customer's home like it was their own. What started as a single truck and a toolbox has grown into a full-service HVAC company with a team of 12 NATE-certified technicians serving all of Boulder County.
We are not a national franchise or a faceless corporation. We are your neighbors. Our kids go to school in Longmont. We shop at the same grocery stores. And we believe that the best business is built one satisfied customer at a time.
Over the years, we have completed more than 5,000 installations and repairs, earned a 4.9-star rating from nearly 300 reviews, and built lasting relationships with homeowners, property managers, and local businesses across the Front Range.
