Hannon Heating and Air

Hannon Heating and Air operates as a family-owned HVAC contractor serving MetroWest Massachusetts, including Bellingham and surrounding communities. The business maintains a strong local presence with a 4.3-star rating drawn from 40 customer reviews, and offers 24/7 emergency service alongside standard weekday hours from 7am to 5pm. Homeowners can request an estimate for any job, with every project beginning an upfront quote to eliminate billing surprises.

This contractor distinguishes itself through several concrete service commitments. Every job starts with an upfront quote, a practice reviewers consistently single out as refreshing in an industry known for opaque pricing. The company handles the complete HVAC spectrum, from high-efficiency gas and oil furnace installation and repair to cooling systems and indoor air quality solutions. A notable thread across reviews involves the honest approach: when a controller failed during an AC replacement, Paul covered the replacement cost rather than passing it to the customer.

Reviewers share specific scenarios that illustrate the service style. When Molly G.'s furnace failed with a baby in the house, Paul spent the entire day making sure heat restored before nightfall. Multiple reviewers describe same-day or within-hour arrival during cold snaps, Ali Cormay noted Paul arrived within an hour on a bitterly cold day when her home had no heat. The recurring name is Paul, described as incredibly responsive, very knowledgeable, and someone who treats customers fairly rather thanmaximizing billable calls.
