Walk down almost any Milford street and you’ll see both fuels. Census-based estimates put roughly 43% of the town’s houses and condos on oil and about the same share on utility gas. Statewide, only about 27% of households rely on petroleum, so Milford leans more oil-heavy than most of Massachusetts. The upside is that gas is already in the ground in a lot of Milford neighborhoods, which can make oil to gas conversion simpler than you’d expect.
When it works out, the change is straightforward. The tank leaves your basement, the delivery schedule goes with it, and one utility bill replaces the oil company’s. Close to three-quarters of Milford’s homes were built before 1980, so basements are often tight, and getting that floor space back is a real gain.
The bigger win is timing. Milford built its name on pink granite, and plenty of houses here were built to last. The heating systems inside them usually weren’t. If your boiler or furnace is 20 years old, you’re replacing it anyway, and converting to gas in Milford can mean changing the fuel and the equipment in one project. An oil furnace conversion to gas also keeps you from putting a brand-new oil system next to an aging tank.
We’ll be straight about savings. State estimates show gas costing less than oil for the average home, but the gap depends on your house, your equipment, and what oil prices are doing that month. You get numbers for your house, not a headline percentage.
Dempsey Energy is a family-owned company that started out delivering heating oil and grew into heating, cooling, and plumbing for homeowners. About 12,000 customers later, that oil background still matters. We know what’s at the end of a fill pipe, what a 30-year-old tank looks like, and what a boiler sounds like right before it quits.
For an oil to gas heating conversion in Milford, that means we can talk about what you’re leaving behind, not just what you’re getting. If your oil system is fairly new, we’ll tell you waiting may make more sense. If a heat pump suits your house better, we install those too and will walk you through the comparison.
Whether you live off Route 16 downtown or closer to Milford Regional Medical Center, you deal with one team. We track service calls and follow up to make sure repairs hold up. Our Dempsey Comfort Club is there after the install. If you’re comparing oil to gas conversion quotes in Milford, ask every contractor who’s handling the tank and the permits.
It starts with one question: is gas available on your street in Milford? We check that before anything else, because the answer shapes the whole conversion. If there’s a main out front, you’re in good shape. If not, the utility has to extend one, which can take months and often depends on neighbors signing up too.
Next, we look at what you have: the age of the boiler or furnace, the tank, the piping, the chimney, and whether old pipe insulation could contain asbestos, which is plausible in houses this age. You get the scope in writing, covering the tank, venting, and permits, so there’s less room for surprises.
Then comes the paperwork. In Milford, only a licensed plumber or gas fitter can pull the gas permit through the Department of Inspections, and the town requires underground, rough, and final inspections. We handle that, and we request the gas service line from the utility, which typically runs about two to four weeks after approval.
Install itself usually takes one to two days: old equipment out, new equipment in, venting, and safety testing. An oil boiler conversion to gas in Milford wraps up once the work passes inspection and the utility sets your meter. Because utility scheduling takes time, spring and summer beat waiting for a January failure.

Gas heating installation in Milford typically runs between $5,000 and $15,000, which is the range for conversions across Massachusetts. Where you land depends on how far the gas main is from your house, how much new piping goes inside, whether your chimney needs a liner, and what the tank situation is. A buried tank or asbestos on old boiler pipes adds work.
Here’s what we include: the street check, utility coordination, permits and inspections through the Town of Milford, removal of the old oil equipment and tank, the new gas furnace or boiler, venting, and safety testing. If asbestos turns up, which is plausible when most Milford houses predate 1980, we coordinate the remediation so you aren’t hunting for another contractor. Financing is available, so ask about it when you request a quote.
The utility handles the service line and the meter. We handle everything inside your house, the tank, and the permits. Knowing that split helps when you compare quotes, because not everyone prices the same scope.
After the install, you can join the Dempsey Comfort Club, our membership program with priority scheduling and ongoing maintenance, backed by 24/7 emergency service. The conversion is scoped to your house, and the Comfort Club is the ongoing piece that keeps the new system looked after.
Gas is in the ground across a good part of Milford, but not on every street. Census-based estimates show roughly 43% of houses and condos on utility gas, so some blocks are fully served and others aren’t. A gas meter on a neighbor’s house is a good sign, but it doesn’t guarantee a main runs past yours.
The fastest way to know is to send us your address. We check availability before we talk about equipment, so you don’t plan an oil to gas conversion that can’t happen yet.
If there’s no main on your street in Milford, the utility can look at extending one. That usually depends on how many neighbors want service, and it can take anywhere from about six months to two years. If your boiler is failing and that timeline doesn’t work, we’ll tell you plainly. It may make sense to replace the oil system or look at a heat pump while you wait.
Oil to gas conversion in Milford typically runs between $5,000 and $15,000, the same range you’ll see across Massachusetts. The spread comes from the distance between the street and your house, how much new gas piping goes inside, whether the chimney needs a liner, and what’s going on with the tank. A buried tank or asbestos on old boiler pipes adds work.
Is it worth it? Mass Save stopped rebating gas equipment on October 1, 2024, so there’s no rebate to soften the number. State estimates show the average gas-heated home paying less than the average oil-heated home, but the difference swings with house size and equipment age.
It pays off most when your oil system is 15 to 20 years old and you plan to stay a while. With so many Milford homes built before 1980, plenty of boilers are in that range. If yours is newer and running well, waiting is a reasonable call.
Yes. In Milford, gas permits have to be pulled by a licensed plumber or gas fitter, so this isn’t something a homeowner can pull on their own. The permit goes through the Town of Milford’s Department of Inspections, and the plumbing permit paperwork includes a workers’ compensation insurance affidavit. We take care of that for you.
The town requires underground, rough, and final inspections, and Milford’s Gas/Plumbing Inspector checks that the installer is licensed. After the work passes, the utility sets the meter. You can’t run the new system on gas until that happens, so it’s worth knowing the inspection sits ahead of your first gas-heated day.
Permit costs vary with the job, so we’ll show you how they fit into your written scope instead of guessing. If you ever want to check a contractor’s license, the state board of plumbers and gas fitters can verify it at 617-727-9952.
The old tank comes out as part of the job. For a basement tank, that means it’s drained and carried out through the house, which is why tight, older Milford basements need a plan before anyone starts. Once it’s gone, you get the floor space back.
A buried tank is a different story. Underground tanks can need an environmental assessment, and if one has leaked, cleanup is a separate and bigger cost. We ask about it up front so it doesn’t surprise you halfway through the project.
Don’t leave a tank sitting in place and forget it. It should be properly removed or abandoned. Rules can vary by town, so we do the work under the permits and inspections required in Milford. If the old boiler piping has asbestos, we coordinate that too, so it’s one project and not three separate phone calls.
Either can be the right answer, and we install both, so you’ll hear a straight comparison. Gas tends to fit when you already have radiators or ducts, gas is available on your street, and you want a lower upfront cost. Heat pumps can make more sense when gas isn’t an option or you want to move away from fossil fuels and your house suits it.
The money has shifted. Mass Save ended rebates for gas, oil, and propane equipment on October 1, 2024, with an exception for low-income households, and it now points incentives toward heat pumps. Massachusetts also launched a winter electric rate discount for heat pump homes, and about 140,000 households received it this past winter.
So don’t assume. If you’re weighing oil heating replacement in Milford, ask for both numbers on your house, including what your electric bill might do. With gas on some Milford streets and not others, the answer can differ between neighbors.
Once gas is confirmed and you’ve signed off, the install itself typically takes one to two days. The waiting is everything around it. The utility service line usually gets done about two to four weeks after approval, though it can run longer, and the Milford permit and inspections have to line up too.
Realistically, plan on several weeks from yes to gas turning on, and longer if a main extension is needed. Spring and summer beat waiting for a cold snap, when failed boilers have everybody calling at once.
If your system dies in the middle of winter, tell us right away and we’ll talk through options while the conversion is scheduled. Start with the street check — it takes the guesswork out of the timeline.
