Cornerstone HVAC

Cornerstone HVAC is a heating and air conditioning company based in East Freetown, serving New Bedford, Dartmouth, Fairhaven, Acushnet, and Fall River, and self-reporting 13 years in business. The company's website names Mr. Westgate as CEO and founder, though the person reviewers describe handling the work and the phone calls, in their own words, is Shayne (spelled Shane in several reviews), who appears by name across dozens of jobs from 2025 into 2026 alongside technicians Jordan and Robert. Customers who hired Cornerstone describe fast, dependable response: a same-day repair on one of the hottest days of summer, a next-morning visit that had central air running again within half an hour, and a callback after several other companies didn't answer the phone at all. Several reviewers separately mention technicians cleaning up thoroughly after themselves and explaining the diagnosis and the fix before starting work; one homeowner credited Shayne with contacting the equipment manufacturer directly to confirm parts for an unusual Navien heating and hot water system, and another noted Robert's patience walking an elderly homeowner through the process. Pricing comes up more than once as reasonable rather than as a complaint, and the company's own site states free estimates. All 23 written Google reviews are five stars, with no negative accounts among them, and 18 of those landed in the past six months, a pattern that holds across both quick maintenance calls and more involved repairs like the Navien system diagnosis. Cornerstone is a good fit for a homeowner in the Greater New Bedford area who wants a responsive HVAC company for everyday air conditioning and heating repair as well as less common equipment, though it's worth noting the website and its reviews name different people as the business's owner.
