Oil to Gas Conversion in New Jersey
Converting is four separate jobs that happen to be quoted together, and the one most often left off a quote is the tank. In New Jersey, where a buried tank can turn into a remediation project, that omission matters more than anywhere.
Leave the building and call from outside — that is an emergency services call, not a service call. A yellow burner flame or headaches that clear when you leave the house point the same way. For no heat in freezing weather, call rather than read on: the risk there is frozen pipes rather than comfort, and it arrives within hours.

The four jobs inside one quote
A conversion is rarely just a boiler swap, and understanding the parts is how you tell a complete quote from a cheap one.
One: the gas service
A supply line from the main in the street, plus a meter. That comes from your utility — PSE&G, New Jersey Natural Gas, South Jersey Gas or Elizabethtown Gas — on their schedule rather than your contractor's, and lead times vary by season and by how much digging is involved. Establish first whether there is even gas in your street; in parts of Sussex, Warren and rural Salem there is not.
Two: the appliance
A gas boiler or furnace, sized properly for the house rather than matched to the oil unit being removed. Oil equipment was frequently oversized, and carrying that error across is a common and expensive mistake.
Three: the tank
Covered in full below, because in New Jersey it is the item most likely to change the total.
Four: the flue
A flue sized for oil is too large for a modern gas appliance. The gases move slower and cooler, condense against the masonry, and that moisture is acidic. Left alone it destroys the chimney from the inside over a few years and can stop the flue drafting properly, which is a combustion safety problem. Relining is the normal answer and it belongs on the quote.
The oil tank, and why New Jersey is different
This is the part that catches people out, and the reason a conversion here needs more care than the same job in a state without New Jersey's history of buried tanks.
Aboveground tanks are straightforward
A tank in the basement or beside the house is drained, cut up and removed. It is disruptive for a day and rarely produces surprises.
Underground tanks are not
Thousands of New Jersey homes have or had a buried oil tank, many installed decades ago with no cathodic protection. They corrode and leak, and a leak is a contaminated soil problem regulated by the New Jersey Department of Environmental Protection. The work is done either by removal or by closure in place, and both are governed processes with documentation attached.
Why the paperwork matters at resale
A tank that was removed or closed properly comes with documentation, and that document is what a buyer's attorney will ask for. A tank that was quietly filled with sand by somebody's cousin twenty years ago becomes a problem at closing rather than at the time. If you are converting, do the tank properly and keep the paperwork.
Grant funding has existed
New Jersey has at various points run funding to help with residential tank removal and remediation. Availability changes, so ask a contractor who does this work here regularly rather than assuming either way.
Is it worth doing?
Timing decides it more than anything else.
Convert when the equipment is due anyway
If the boiler or furnace is at end of life, you are buying a replacement regardless — so the conversion cost is the difference between a gas appliance and an oil one, plus the service, tank and flue work. That is a very different sum from converting perfectly good equipment, which rarely pays back.
Price a heat pump against it before committing
This is the step most people skip. If you are already opening up the heating system and there is no gas in the street, a cold-climate heat pump avoids the service line and the flue entirely, and New Jersey stacks a state rebate with a utility one. Against oil at current prices the running-cost comparison is often favorable. It deserves a genuine quote rather than a dismissal.
What actually changes on the bill
Gas is generally cheaper per unit of heat than oil, though the gap moves with markets and neither is fixed. The more reliable savings are the ones nobody quotes: no deliveries to schedule, no running out in February, no tank to worry about, and a meaningfully more efficient appliance than the one being removed.
Oil to Gas Conversion — frequently asked questions
Do I have to remove the oil tank?
Not always — closure in place is a recognized option for some underground tanks — but it has to be done properly and documented either way. What you should not do is leave an abandoned tank undocumented: it becomes a title and disclosure problem at resale, and if it has leaked it is a remediation matter regulated by NJDEP.
How long does a conversion take?
The appliance work is usually a few days. The calendar is set by the utility service line and meter, which can take weeks depending on season and how much excavation is needed. Start the utility application early — it is the long pole, not the boiler.
Why does the chimney need lining?
A flue sized for oil is too large for a modern gas appliance. The gases travel cooler and slower, condense against the masonry, and that condensate is acidic. Over a few years it deteriorates the structure from inside, and a flue that stops drafting properly is a combustion safety issue rather than a maintenance one.
Is there gas in my street?
Most of built-up New Jersey has gas at the main, but not all — parts of Sussex, Warren, and the rural south are propane and oil country. Your utility can confirm against your address, and it is the first question to settle because everything else follows from it.
Should I convert or install a heat pump?
Worth pricing both, particularly if there is no gas in the street — a heat pump avoids the service line and the flue relining entirely, and New Jersey stacks a state rebate with a utility one. Against oil the running-cost comparison is often favorable. Against cheap natural gas already at the property, conversion usually wins.
