You want one answer before anything else: can you get gas at your house? In a town with more than 160 miles of road, that answer changes from one street to the next. We start every oil to gas conversion in Sudbury, MA with that question, so you never spend time on a plan that can’t happen.
Once you know, the rest gets simpler. If a main runs past your house, oil to gas heating conversion in Sudbury comes down to a service line from the utility and a new system inside. If a main doesn’t, you hear that up front and can weigh a main extension against a heat pump.
More than half of Sudbury’s homes went up between 1950 and 1980, and plenty of them were heated with oil from the start. If your boiler or furnace is original or close to it, oil heating replacement in Sudbury is happening either way. The only real question is what you replace it with. High-efficiency gas equipment runs at 90 to 95 percent, where older oil units sit around 70 to 80. About 90 percent of homes in town are owner-occupied and often held for years, so you’ll likely be around long enough to see the payback.
And when the tank leaves, your basement gets its space back.
Dempsey Energy is a family-owned HVAC and plumbing company that started out delivering oil. So when you say you’re tired of the tank, the delivery schedule and a burner that’s been running since before you owned the house, we know exactly what you mean. It’s also why we’ll tell you to keep your oil system if it’s fairly new.
We’ve grown to more than 12,000 homeowners across Middlesex County, and our focus is residential. We track every service call and follow up to make sure repairs hold up. That matters more to us than any claim about being the best.
We work with Sudbury homeowners whether you’re off Route 20, near Route 27, or out on a quiet road in North Sudbury. We don’t have an office in town, and we won’t pretend we do. What you get is one point of contact for gas heating installation in Sudbury, from the permit to the old tank, plus a check-in after the work is done.
First, we find out whether gas runs past your house and how far the main sits from your door. That distance is one of the biggest things that moves your price. We also look at the age and condition of your current system, because a newer one may not be worth replacing yet.
Next is the paperwork. A licensed gas fitter pulls the gas permit through the Sudbury Building Department, and we coordinate the service line and meter with the utility. Once service is approved, the utility often completes the line in two to four weeks, sometimes longer.
Then comes the swap. An oil boiler conversion to gas in Sudbury, or an oil furnace conversion to gas, typically takes one to two days. We remove the old equipment, set the new gas unit, add venting and a chimney liner if your chimney needs one, and test everything. We also handle oil tank removal and coordinate asbestos remediation if your old boiler piping has it.
A Sudbury inspector signs off before the utility sets your meter. After that, you’re on gas. Utility scheduling is the slow part, so late spring through early fall gives you the best shot at being ready before heating season.

Your conversion covers the system assessment, utility coordination, permits, removal of the old oil equipment and tank, a new high-efficiency gas furnace or boiler, venting, and safety testing. Heating system conversion in Sudbury is one job with one contact. You don’t have to chase an installer, a tank crew and a permit runner separately.
Across Massachusetts, these conversions typically run $5,000 to $15,000. What moves your number is house size, how much piping the job needs, how far the service line runs from the street, chimney lining, and the tank. Many Sudbury homes sit on larger lots, so the run from the road to your basement is worth asking about.
Mass Save stopped paying rebates for gas equipment on October 1, 2024, except for low-income households. If an ad promises one, ask to see it in writing. On a $5,000 job with $1,000 in yearly savings, payback is about five years. That’s an estimate, not a promise.
Afterward, you can join the Dempsey Comfort Club, our membership program with priority scheduling for routine and emergency calls, member discounts on service, and extended warranty options. Details can vary, so ask what’s included for your system. Financing is available, and we install heat pumps too, so you can compare before you decide.
Start with the utility. The town’s community profile lists National Grid and Eversource Gas as natural gas providers, and which one serves you depends on your street. We haven’t found a public street-by-street map for Sudbury. With about 160 miles of road, it’s common for one road to have a main while the next one over doesn’t.
The quickest route is to give us your address. We contact the utility, confirm whether a main runs on your road, and measure the distance to your house, since that run affects your cost for oil to gas conversion in Sudbury. If there’s no main, we’ll walk you through the extension path, including neighbor sign-up. Timelines there can run from six months to two years. We’ll also tell you honestly if a heat pump makes more sense for your house.
Across Massachusetts, a typical conversion runs $5,000 to $15,000. The final number depends on house size, piping length, the distance from the street main to your house, chimney lining, and whether your oil tank is above ground or buried. We don’t put a price on a Sudbury house without seeing it, because larger homes and longer runs can push you toward the upper end of that range.
We estimate savings of $1,000 or more per year for most Sudbury homeowners. On a $5,000 job with $1,000 in yearly savings, you’d recoup the cost in about five years. Your actual savings depend on gas rates, your equipment, and how much you use.
Financing is available. Ask us for a written scope and quote so you can compare it line by line.
No. Under the 2021 Climate Act, rebates and financing for gas, oil and propane heating equipment ended on October 1, 2024. The one exception is for low-income households. If you see an ad in Sudbury promising a rebate for an oil to gas conversion, ask for the details in writing, because that offer is out of date.
Mass Save now puts its money toward heat pumps. National Grid cites rebates up to $13,500 and 7-year 0% financing, and what you qualify for depends on your electric utility.
So the math for gas has to work without a rebate. That usually means looking at your current system’s age. If your oil boiler or furnace is failing or close to it, you’re paying for a replacement anyway, and converting to gas becomes a much easier decision.
It depends on your house, and we install both, so we don’t have a reason to steer you. Gas tends to fit when you already have radiators or ductwork you want to keep, gas is at or near your street, and you want a lower upfront cost than a whole-home heat pump. A heat pump makes more sense when gas isn’t available or the extension isn’t realistic.
If your oil system is only a few years old, the best answer may be to wait. For oil boiler conversion to gas in Sudbury, we’ll look at your existing system, your street, and how long you plan to stay. Then we’ll tell you plainly which one we’d choose in your house.
If you’ve been looking up oil to gas conversion near you, you’ve probably seen timelines that skip over the utility. The conversion work itself typically takes one to two days. The service line is the slower piece, and the utility often completes it two to four weeks after approval, sometimes longer.
Because we coordinate the utility, permit and installation, we sequence the work so the swap happens when gas service is ready. A Sudbury Building Department inspector signs off before the utility sets your meter, so build that step into your calendar too.
Nearly 8,000 Sudbury residents commute out for work, so we’ll give you a clear timeline and one person to call. That makes it easier to plan around your schedule. The best window is late spring through early fall, well before the first cold snap.
Tank removal is part of the job. Don’t leave an old tank sitting in your basement. If your tank is buried, it can need an environmental assessment, which can change both cost and timeline. Tank rules vary by municipality and fire department, so we confirm the requirements before we price that part.
For oil to gas conversion in Sudbury, the Building Department issues the gas permit, and a licensed Massachusetts gas fitter pulls it. An inspector signs off before the utility sets your meter. We handle the paperwork and the scheduling.
You can check any gas fitter’s license with the state board at 617-727-9952. It’s worth doing, and you should ask for a written scope that lists the tank, the permit, venting and piping before you sign anything.
