HVAC Contractor in Franklin, MA

Heating and AC for Franklin homes from Bellingham, the next town over — 10 to 15 minutes straight up Rt 140.

Hannon Heating & Air Conditioning is an HVAC contractor serving Franklin, MA from Bellingham, the next town over — 10 to 15 minutes straight up Rt 140. We repair and replace furnaces, boilers, central AC, and heat pumps, service oil heat, and pull Franklin permits ourselves. Franklin is one of our closest, busiest service areas.

Fifteen Minutes Up Rt 140

We're based in Bellingham, and Rt 140 runs straight from us into Franklin. Most Franklin calls are a 10-to-15-minute drive, which is why same-day service is often realistic. We're in town regularly, from the homes around Franklin Common and the downtown cultural district near Dean College out to Forge Park and the neighborhoods by DelCarte Recreation Area. To be clear about how we work: there is no Franklin office. The trucks roll from Bellingham, and when you call (508) 282-1000, you're talking to the people who do the work.

Franklin's Colonial Subdivisions Are Coming Due

Big colonial subdivisions from the 1970s through the '90s dominate Franklin, the newest housing stock anywhere in our service area. Those houses are now 30 to 50 years old, and their ducted furnaces and central AC systems are aging out together. That's full-system replacement territory, so we do a lot of furnace installation in Franklin, along with central AC installation for colonials that never had cooling in the first place. A four-bedroom colonial is also a natural dual-zone candidate: upstairs and downstairs on separate thermostats, so the second floor stops overheating in July. Estimates on system replacements are free.

Oil Heat in Franklin

Gas is available town-wide in Franklin through Eversource, but roughly one in five Franklin homes still heats with oil. We work both sides of that line. For the oil homes: burner cleanings, repairs, and Roth double-wall tank replacements — we're Roth certified. For homeowners ready to switch, oil-to-gas conversion is a job we manage end to end: new equipment, coordination with the utility, tank removal, and permits. And because we service oil every week, we'll tell you plainly when your oil system has good years left and conversion isn't worth it yet.

Older Homes Around Franklin Common

The antique homes around the Franklin Common Historic District run on boilers, with radiators or baseboard and no ductwork anywhere in the house. We service and replace old boilers, gas and oil both, and we're comfortable in houses where the heating system has outlived several owners. When these homeowners want cooling without tearing the place apart, ductless equipment is usually the answer — more on that in the FAQ below.

Permits Through Franklin Building & Inspections

Heating and cooling replacements in Franklin need permits, and we pull them ourselves. Franklin's Building & Inspections department at 355 E Central St runs online permitting, which keeps the paperwork quick — you don't chase forms or make trips to town hall. We file the permit, schedule the inspection, and close the job out properly. That matters later: an unpermitted furnace swap has a way of surfacing during a home sale.

No heat or no cooling? Emergency service is available.

Frequently Asked Questions

Do you serve Franklin, MA?
Yes. Franklin is one town up Rt 140 from our Bellingham base and one of our closest, busiest service areas. We handle repairs, tune-ups, and full system replacements there year-round.
How fast can you get to Franklin?
Often same-day. Franklin is a 10-to-15-minute drive from Bellingham, so fitting a Franklin call into the day's route is usually manageable. For a no-heat or no-AC emergency, call (508) 282-1000 — emergency service is available; we pick up when we can and call right back when we miss you.
What heating systems are common in Franklin homes?
The 1970s–90s colonial subdivisions mostly run ducted gas or oil furnaces with central AC sharing the ductwork, and both tend to age out together. The antique homes around Franklin Common have boilers and no ducts. We work on all of it, gas and oil alike.
Can you add AC to an older Franklin home without ductwork?
Yes. Ductless mini splits fit houses like the ones around the Common: one outdoor unit feeds quiet wall units in the rooms you choose, with no ductwork cut into an antique house. The cold-climate models heat too, which takes load off an old boiler in the shoulder seasons.
