HVAC Contractor in Millis, MA
Furnace replacement, first-time central air, and oil-to-gas conversion for Millis's mid-century ranches and capes.
Hannon Heating & Air Conditioning is an HVAC contractor serving Millis, MA from Bellingham, 15 to 20 minutes up Rt 126 through Medway and east on Rt 109. Millis is the mid-century town of our area: 1940s–60s ranches and capes on their third generation of equipment. Furnace replacement, first-time central air, and oil-to-gas conversion are the jobs we run here most.
Through Medway, Into Millis
The drive is Rt 126 north through Medway, then Rt 109 east into Millis center — 15 to 20 minutes from our Bellingham base. We cover the whole town: the center blocks near Richardson's Tavern, a c. 1720 stop that once hosted George Washington; the village streets of Clicquot, named for the Clicquot Club factory that bottled the first ginger ale in the country and ran for about 80 years; and the roads out toward the Charles River and South End Pond. There's no Millis office; the trucks and the phone both live in Bellingham.

Third-Generation Equipment in Mid-Century Houses
A 1950s ranch is often on its third heating system by now, and number three is wearing out. We replace furnaces and boilers in these houses regularly, sized to the actual house instead of copied off the old nameplate, and furnace installation estimates, like all our system replacement estimates, are free. The older stock near the center and the two-families around Clicquot run boilers and radiators, and we service those alongside the mid-century ducted work. If the current system has honest years left, a tune-up and a repair beats a premature swap, and we'll tell you which side of that line you're on.
Central Air, Finally
Plenty of Millis capes and ranches have never had real cooling beyond window units. Where the ductwork supports it, central AC installs cleanly onto the existing furnace plenum; where it doesn't, ductless wall units handle the bedrooms without opening walls. Single-story ranches are the easiest central-air candidates we see, and Millis is full of them.
The Best Gas Coverage Around
Most Millis homes still heat with oil, but Eversource's gas coverage is stronger here than in the towns around us, which makes Millis the place where oil-to-gas conversion most often makes sense. We check your street's main first, then quote the whole conversion: equipment, utility coordination, tank removal, permits. And when oil still wins for your house, we'll keep the burner tuned and say exactly that.
Permits at the Veterans Memorial Building
Millis permits replacement work through the Building Department in the Veterans Memorial Building at 900 Main St, with online applications. We pull the permit, schedule the inspection, and close out the job ourselves.
