While it has fallen out of favor in recent years, heating oil is still used to heat homes and commercial buildings across the country.

The U.S. Energy Information Administration reports that in winter 2023-2024, about 4.79 million U.S. households relied on it as their main heating fuel. And about 82% of those households were situated in the Northeast part of the U.S.

If you’re one of the Americans who depends on heating oil, you should know that recent increases in gas and oil prices could make heating your home more expensive than usual this month. U.S. crude oil briefly hit $120 a barrel late Sunday, before dropping Monday afternoon to $95, and then settling at $86 after President Donald Trump said the Iran “war is very complete” later that day.

Even with the prices of oil starting to decline, there are other ways to keep your costs down and ease the burden on your wallet.

Since heating oil and gas are both refined from crude oil, heating oil costs and gas prices are closely related.

When the cost of crude oil goes up for any reason, gas and heating oil prices rise simultaneously. That’s why homes that rely on heating oil usually face higher utility bills when gas prices in their area increase.

“Crude oil is up 52.9% year to date, heating oil is up 10.5%, and natural gas is up 5.4%. Almost 5 million U.S. households depend on heating oil. For a typical home consuming 1,000 gallons of heating oil annually, that’s an increase of $1,000 for the year,” says Heather Eason of Select Power Systems in Ridgeway, SC.

Even a small change in crude oil prices can quickly increase heating costs, adding hundreds of dollars to a heating bill.

“Unfortunately, this situation puts millions of heating oil households at risk because oftentimes they can’t switch to alternative fuel. Some areas simply do not have natural gas pipelines,” explains Jon Gilbertsen, HVAC professional and president of Chris Heating & Cooling in Chicago.

Nick Barber, co-founder of Payless Power in Dallas, points out that heating oil consumers also face the challenge of having to pay for fuel deliveries in advance.

“If prices rise in January or February, there is no way to delay heating needs during extreme cold snaps. Natural gas consumers often have the advantage of utility billing plans that allow them to space their bills over multiple months,” Barber notes.

If you rely on heating oil to keep your home warm and comfortable, these tips could help save you some money.

Eason recommends asking your supplier if it offers pre-buy plans that spread costs over a 12-month period or lock in a price. Gilbertsen echoes her advice and explains that this strategy can protect you from sudden price spikes during winter and large lump sum payments.

“Attic insulation, sealing cracks in walls and windows, and replacing single-pane windows with double-pane windows can lower heating demand by 10% to 30%,” says Gilbertsen.

While window replacement is expensive, things like weather-stripping, caulking, and even attic insulation are lower cost and pay off almost immediately.

Plus, there are federal incentives you can take advantage of, such as the Energy Efficient Home Improvement Credit. This credit supports insulation and HVAC upgrades and can cover about 30% of qualifying improvement costs.

If possible, get an energy efficiency audit by an approved expert. These audits are usually fairly inexpensive. “In Maryland, for example, the cost is subsidized by the energy companies and a certified audit only costs $100,” says Nic Briggs, co-owner and HVAC Division Leader at Service Force Plumbing in Rockville, MD.

An energy auditor will provide a wide variety of recommendations including air sealing, improved insulation, furnace or heat pump improvements, and other potential solutions.

Traditional heat pumps can only heat effectively above 40 to 45 degrees Fahrenheit. For temps below that, they rely on auxiliary radiant coils that are both energy inefficient and expensive to run.

“New inverter models, however, can efficiently produce heat down to 5 to 10 degrees outside before the backup element kicks in. In most regions of the country this could cover most or all of the coldest nights of the year,” explains Briggs.

Gilbertsen says an upgrade to a newer system only makes financial sense if the system you currently have is already old or close to replacement and/or you plan to stay in your home for a while.

“A modern heat pump typically costs around $14,000 to $20,000 to install, but can cut heating costs by 20% to 40%, and many households currently spend $2,800 to $3,500 per year on heating oil. In most homes in the Northeast, a new HVAC system pays back in roughly 8 to 15 years,” adds Gilbertsen.
