Our services include HVAC repair and maintenance for ductless mini-splits, gas furnaces, radiant heating systems, heat pumps, and ductwork. We serve both residential and light commercial clients who value craftsmanship, safety, and reliability.

What makes us different is our commitment to hands-on work. Many HVAC companies send out teams with varying experience levels, but at O’Hara, every job benefits from my direct involvement. That means better communication, cleaner installations, and long-lasting comfort solutions.

We are certified, insured, and proud to be a MassSave installer, helping customers take advantage of local rebates. From tune-ups to full installations, we take the stress out of HVAC work with friendly, straightforward service that Worcester residents can trust.
