About Cornerstone Heating & Air
Founded in 1989, Cornerstone Heating & Air has built a reputation in Boston, MA as a straight-shooting well-respected 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 & Air serves homeowners across Boston, MA and surrounding ZIP codes including 02108, 02115, 02125, 02127, 02130. Pricing is up-front and quoted in writing before any work begins, with no obligation if the estimate isn't right for your project.
