Converting from heating oil to natural gas is one of the most common home energy upgrades in the Northeast. Total conversion costs typically range from $4,500–$12,000: new gas furnace or boiler ($2,000–$6,000), gas line installation ($300–$1,500), gas meter installation (often free or subsidized), oil tank removal ($1,500–$3,500), and permits ($200–$600).
The oil tank is the most overlooked variable in the conversion. Above-ground tanks cost $400–$900 to remove. Underground tanks require excavation, soil sampling, a state permit, and a formal closure report — $1,500–$3,500 for a clean tank. Never abandon a tank in place: most homeowners insurance policies will not cover contamination from a deliberately abandoned tank, and it will surface as a liability when you sell.
For most Northeast homeowners, the payback period is 4–8 years. A typical home spending $2,400/year on oil might spend $1,200–$1,600/year on gas — annual savings of ~$1,100. Many utilities offer rebates of $500–$2,000 for high-efficiency gas equipment. The Inflation Reduction Act provides a 30% federal tax credit up to $600 for qualifying equipment.
If natural gas is not available on your street, alternatives include propane (LP gas) with an above-ground tank, air-source heat pump (most efficient, qualifies for 30% federal tax credit), or a modern high-efficiency oil burner. Propane is most common in rural areas without gas mains.

QWhat happens if contamination is found during tank removal?
If soil contamination is discovered during tank removal in United States, additional soil must be excavated and properly disposed of at an approved facility. Soil samples are taken to determine the extent of contamination. The state environmental department may need to be notified, and a Licensed Site Professional may be required to oversee remediation and certify cleanup completion.
QShould I remove an old oil tank before selling my house in United States?
