About Cornerstone Heating & Cooling
Founded in 2017, Cornerstone Heating & Cooling has built a reputation in Winston-Salem, NC as a straight-shooting locally-owned hvac contractor that doesn't push system replacements when a repair will do. The team is unusually rigorous about indoor air quality and ventilation work in addition to core heating and cooling, and is one of the few local shops that will quote both a repair and a replacement option on the same visit so homeowners can make an informed call. NATE-certified, state-licensed, EPA refrigerant-handling certified, and proudly insured.
Cornerstone Heating & Cooling serves homeowners across Winston-Salem, NC and surrounding ZIP codes including 27101, 27103, 27105, 27106, 27107. Pricing is up-front and quoted in writing before any work begins, with no obligation if the estimate isn't right for your project.
