Twelve permits between 2015 and 2025 trace Gondolfo HVAC's work north and west of Boston — furnaces, condensers, ductwork and sheet-metal venting in Haverhill, Beverly, Somerville, Newtonville and Burlington. The business works out of 45 Haseltine St in Haverhill. It is a one-person shop. The Better Business Bureau describes a sole proprietorship owned by Christopher Gondolfo with a 3/1/2011 start date and 15 years in business, and grades the profile A+ without BBB accreditation. BuildZoom scores it 91, which it puts in the top 37% of the 139,240 licensed Massachusetts contractors it tracks, and lists the services as HVAC, sheet metal and mechanical work. BuildZoom also lists a Massachusetts sheet metal journeyperson licence, #7386, for the business. Look that number up on the state's licence register yourself before work starts — the register is where a trade licence's current standing lives. For a heating or cooling replacement in a single-family house, a contractor with a decade of permitted furnace and condenser swaps behind him is a sensible call. With one person on the books, ask how a multi-day install gets scheduled, get the equipment model and the scope in writing, and ask for proof of liability insurance.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Gondolfo HVAC. Use it to sanity-check bids, then get the real number in writing.
