Hannon Heating & Air Conditioning handles oil-to-gas conversions in Bellingham, MA and the MetroWest towns nearby, from checking whether gas is on your street through equipment installation, tank removal, and startup. We work on both fuels every week, so you get a straight answer on whether converting makes sense for your house at all. We handle conversions in Franklin, Millis, and Medway as well as Bellingham.

The Three Parts of a Conversion

A conversion is really three jobs that have to land in order. First, the utility runs a service line from the main to your house and sets a meter — their crew, their schedule. Second, we install the new gas boiler or furnace and its venting; your radiators, baseboards, or ducts stay put. Third, the oil side gets decommissioned properly: remaining oil pumped out, the tank removed under a fire-department permit, and, in most conversions, a stainless steel liner in the chimney, because gas exhaust condenses in a flue built for oil and eats the masonry. We coordinate all three so you make one call instead of refereeing three schedules.

The Honest Timeline: Start in Spring, Not October

Our part of a conversion takes one to three days. The utility's part is the long pole: getting the street connection approved, scheduled, and dug commonly takes weeks, and it stretches longer when everyone else has the same idea in the fall. So the calendar advice is simple — decide in spring or summer, when the utility's queue is short and your heat isn't hostage to it. A conversion begun in October can leave you paying for oil deliveries while you wait on trenching. Since the old tank comes out anyway, oil tank removal rides along under the same permit process we already handle.

Is Gas Even on Your Street?

Before anyone spends money, find out whether the main reaches you. Gas availability in the MetroWest towns is street-by-street: one road has a main, the next was never trenched, and a main can stop three houses short of yours. Extending a main is sometimes possible and sometimes prohibitive, and some Massachusetts utilities have paused or slowed new hookups in recent years, which changes the answer by town and by year. We check with the utility as the first step of any conversion conversation, and if the answer is no, we tell you before a single piece of equipment gets quoted — and talk through what actually is available for your house.

Will Converting Actually Save You Money?

A straight answer: much of the saving people attribute to gas really comes from the equipment swap, because conversions typically retire an old low-efficiency oil unit and install 90-plus-percent gas equipment. Fuel pricing is the other half — oil prices swing hard year to year while regulated gas rates move more slowly, and plenty of homeowners convert as much for that predictability as for any single winter's numbers. And if you are weighing a conversion, it is fair to weigh skipping gas entirely: a cold-climate heat pump heats and cools with no fuel line at all, and we install both, so the comparison you get from us is between two jobs we would be equally glad to do. Ask us to run the feasibility check and start with real facts about your street and your system.

Frequently Asked Questions

How long does a conversion take from first call to gas heat running?
The installation itself takes one to three days; the whole project usually spans several weeks, because the utility's street connection sets the pace. Approval, scheduling, and trenching for the service line commonly take weeks on the utility's calendar. Start in spring or summer and the wait costs you nothing; start in late fall and you may be buying oil while you wait.
Do my radiators, baseboards, or ducts have to change?
No. The distribution system stays; only the boiler or furnace and its venting change. The chimney is the one piece that usually needs work, since gas exhaust condenses and damages a flue sized for oil, so most conversions include a stainless liner unless the new equipment side-vents in PVC. That is in the quote from the start.
How do I find out if gas is available on my street?
Ask the utility, and we make that inquiry for you as step one. Availability is street-by-street, mains sometimes stop short of a given house, and extension policies and new-hookup rules vary by utility and change over time. Checking costs nothing, and the answer decides everything else, so we confirm it before quoting any equipment.
What happens to my old oil tank and the oil left in it?
The usable oil gets pumped out, and the tank is removed under a local fire-department permit with the disposal documented. Don't leave a dead tank in the basement; abandoned tanks corrode, complicate home sales, and can leak long after the last delivery. Tank removal is built into our conversion scope, permits and paperwork included.
Should I skip gas and go straight to a heat pump instead?
It is a fair question, and for some houses the answer is yes. A cold-climate heat pump heats through a Massachusetts winter, adds central cooling, and skips the utility trenching wait entirely, while a gas conversion keeps familiar equipment and may suit the house better where the ductwork, radiators, or budget point that way. We install both, so we compare them honestly against your house instead of steering you.

Thinking About the Switch?

Estimates on full system replacements are free — and if keeping oil makes more sense for your house, we'll tell you that too.
