HVAC Service in Lewisville, TX

Dependable Indoor Air Quality, Heating & AC Repair & Installation in Denton County 

Northside Air Conditioning has been a trusted name for HVAC services in Lewisville since 2004. Our full-service company handles the heating, cooling, and indoor air quality of your home, business, or commercial property to keep you comfortable.

We have relationships with many major manufacturers and have the experience to work on any make or model, but we most often recommend American Standard for the brand’s exceptional performance and reliability. All of our work comes backed by warranty—1 year parts and labor on repairs, 5-10 years parts and labor on new equipment, and a lifetime workmanship warranty on new installations—so you can rest easy. We offer free estimates on new equipment, as well as free second opinions on repairs.
