Before anyone talks about equipment, you need to know whether gas actually reaches your house. In Northborough, the answer changes from street to street. The village center along Main Street is far more densely settled than the roads toward the edge of town, and gas mains tend to follow the density.
So the first thing oil to gas conversion in Northborough gives you is a straight answer. You learn whether you’re looking at a short hookup, a longer run, or a house where the numbers don’t work. You learn it before you’ve paid for a plan that can’t happen.
If gas does reach you, the payoff is a heating system you stop thinking about. Many Northborough homes were built between the 1940s and the 1990s, and the typical listing runs around 2,400 square feet. Those original systems are likely at or past the 15 to 20 year mark. That’s when gas heating installation in Northborough stops being an extra expense and becomes the replacement you were going to buy anyway.
Then there’s the math. Contractors around Massachusetts quote savings of roughly $800 to $1,000 a year compared with oil, and a typical conversion runs $5,000 to $15,000. If you’re staying ten years or more, that adds up. The oil tank comes out of your basement and the delivery calls stop, too.
Dempsey Energy is a family-owned HVAC and plumbing company that started out delivering heating oil. That matters when you’re leaving oil behind, because we know the system from the delivery truck side as well as the basement side. Some Northborough homeowners have bought from the same oil dealer for decades, so we don’t treat switching as a small decision.
We’ve grown into heating, cooling, and plumbing work for over 12,000 homeowners across our service area. That’s a company-wide number, not a Northborough count. It’s the reason we track every service call and follow up after the work is done.
On a job here in Worcester County, you get a written scope and price before work starts, a heads-up if something changes, and a call after the install. When you’re deciding who should handle your oil to gas conversion in Northborough, ask to see the license. You should ask every contractor that, us included.
The first step is the gas check, and it comes before any equipment talk. Eversource is Northborough’s gas utility, and it has an address-based availability tool on its website. We walk your house next. We look at the age and condition of your oil furnace or boiler, where a gas line would come in, how long the piping run is, and whether the chimney needs a liner.
Next you get a written scope and price. It covers the new equipment, piping, venting, permits, and the oil tank, along with anything unusual like asbestos on old boiler piping. For oil to gas heating conversion in Northborough, the typical Massachusetts range is $5,000 to $15,000, and the scope shows you where your house falls.
Then comes the paperwork. Northborough takes all permits online and requires a separate gas permit for each dwelling unit. Eversource installs the service line and meter, and its timing varies, so we plan around it. Once gas service is in place, the heating system conversion in Northborough itself usually takes one to two days. The town’s gas inspector signs off, the meter gets set, and we follow up with you.
If you can start in spring or summer, do. Scheduling gets tighter once oil systems start failing in the first cold snap.
Ready to get started?
Your oil furnace conversion to gas in Northborough covers the whole inside of the house. That starts with a new gas furnace or boiler sized to your home with a proper load calculation, which matters in a town where many houses run well past 2,000 square feet. High-efficiency models reach 95% or better, compared with the 70 to 80% range of older oil units.
An oil boiler conversion to gas in Northborough also covers the gas piping, venting, a chimney liner if yours needs one, and removal of the old equipment and the oil tank. If there’s asbestos on old boiler piping, which turns up in older houses, we coordinate the remediation. Whether you’re near the First Parish Church end of Main Street or on a side street off Church Street, the scope is written down before work starts.
Eversource handles the service line and meter. We handle the town side: the online gas permit, the separate permit each dwelling unit needs, and the inspection. We also install heat pumps and ductless mini-splits, so if gas isn’t the right fit, you’ll hear that from us.
After the install, you can join the Dempsey Comfort Club, our maintenance and membership program. It includes priority scheduling for routine and emergency calls, member discounts on service, and extended warranty options. Details can vary, so we’ll go over them with you. Financing is available, and equipment typically carries a manufacturer warranty of 10 to 20 years. We put any labor warranty in writing.
Start with Eversource. The utility serves Northborough, and its website has an address-based check that tells you whether there’s a main on your street. Confirm it for your own address. There’s no public street-by-street map to browse, which is why searches for oil to gas conversion rarely settle the question on their own.
Homes near the village center and along the busier corridors are more likely to have a main close by. Longer outlying roads in Northborough are less certain, and nobody can honestly promise gas town-wide.
If there’s no main on your street, you’re looking at a utility main extension, which often depends on neighbors signing up and can take anywhere from about six months to two years. Or you stay with oil, or look at electric. We’ll tell you which one makes sense for your house.
For oil to gas conversion in Northborough, expect the typical Massachusetts range of $5,000 to $15,000. Where you land depends on how far the main is from your house, how long the piping run inside is, whether the chimney needs a liner, and what’s happening with your oil tank. Removing an above-ground tank commonly runs $500 to $1,500, while an underground tank can run $1,000 to $3,000.
Bigger houses cost more to heat and more to size correctly, and many Northborough homes run large. Contractors usually quote savings around $800 to $1,000 a year. A $5,000 job saving $1,000 a year pays back in about five years, but treat that as an estimate. We put your real number in writing after we’ve seen the house.
Yes. Since June 1, 2022, Northborough has taken building, plumbing, gas, and other permits through its online permit portal only. Gas work needs its own permit for each dwelling unit, and the fee doubles if work starts before the permit is in place. The gas fitter has to hold a valid Massachusetts license and insurance, and be registered with Northborough’s Gas Department before a permit is issued.
After the work, the town’s gas inspector checks it. Plumbing and gas inspections generally happen on weekday mornings with 24 hours’ notice. We handle the paperwork and scheduling on our jobs so you aren’t chasing anyone. You should still ask any contractor, us included, to show you their license.
No. Under the state’s 2021 Climate Act, Mass Save stopped offering rebates and financing for gas, oil, and propane heating equipment on October 1, 2024. A low-income exception remains. That’s a statewide rule, so it applies in Northborough like everywhere else. If you see an older page promising a gas conversion rebate, it’s out of date.
What that changes is how you judge the job. Without a rebate, the strongest case is the replacement moment. Your oil furnace or boiler is 15 to 20 years old, you need a new system either way, and you’re weighing gas against another oil unit or a heat pump. Mass Save now puts its incentives behind heat pumps, so check what’s available for your address. Financing is available on installs, and we’ll run the numbers with you.
It depends on your house, and we install both, so we’re not pushing one. Gas tends to fit when you have radiators or ductwork you want to keep, gas is available on your street, and you want a lower upfront cost. A heat pump can make more sense if gas can’t reach you, if you’re also adding cooling, or if you want to use the heat pump incentives.
Older, larger houses like many in Northborough often have existing radiators or ducts, so the layout matters as much as the fuel. Electric rates matter too. And if your oil system is only a few years old and running well, the honest answer may be to leave it alone for now. We’d rather say that than sell you a conversion that won’t pay off.
The tank comes out as part of the job. An above-ground basement tank is the simpler case. An underground tank can require an environmental assessment, especially an old one, so we look at that on the first visit instead of finding out mid-job. Typical Massachusetts removal costs are $500 to $1,500 above ground and $1,000 to $3,000 underground. Tanks around 20 years old are common candidates for replacement anyway, and once it’s gone you get the basement space back.
On the delivery side, cancel with your oil dealer once the gas is running, not before, so you’re never without heat. Ask the dealer about any oil left in the tank first. Northborough has long-established dealers, and plenty of homeowners have used the same one for years. Gas heating installation in Northborough is a good reason to make that call, but there’s no rush to make it early.
