There are oil tanks in basements across the Lower Hudson, from Fisher Hill colonials to prewar homes in New Rochelle and Mamaroneck, and every one of them represents a decision the homeowner re-makes by default each fall: schedule another delivery, or finally run the numbers on something else.
This guide runs those numbers. Not brochure claims, not vibes: a worked comparison between staying on oil and converting to a cold-climate heat pump in White Plains, built from illustrative math you can rebuild with your own delivery receipts and electric bill in twenty minutes.
The Oil Problem, Stated Plainly
Oil heat carries two structural costs in 2026, and neither is your furnace's fault.
The first is the fuel. Heating oil is priced by global markets, delivered by truck, and burned at whatever efficiency your particular unit manages, which for many older Westchester furnaces means a real slice of every gallon leaves through the flue. A typical single-family home in this climate can burn 800 to 1,000 gallons a season.
The second is volatility. Oil customers get no rate case and no commission hearing. The price moves when the market moves, and your only hedge is the size of your tank. Anyone who heated a Westchester house through recent price spikes knows the feeling of watching the gauge and the news at the same time.
A heat pump converts the same job to electricity and does something combustion cannot: it moves heat instead of making it. Its effective efficiency runs at multiples of any furnace, which is the entire reason the annual math below tilts the way it does.
The Cold Question, Answered With a Number
Every homeowner asks the same thing first: does it work when it is actually cold here?
The honest answer starts with the winter climate. White Plains carries a heating winter climate, meaning systems here are sized for coldest nights, not for the average January afternoon. Modern cold-climate heat pumps on the NYS Clean Heat / NEEP-qualified list are built and tested to deliver real heating capacity at temperatures like these; qualifying for that list is precisely what separates them from the mild-climate units that gave heat pumps a bad name decades ago.
Sized correctly to a cold night from the qualified list, a cold-climate system carries a Westchester winter as the primary heat. Undersized, or built from off-list equipment, it does not. The difference is the contractor and the load calculation, not the concept, and our guide to the best cold-weather heat pumps for White Plains covers exactly what to demand on a quote.
The Worked Comparison
Take an illustrative 2,000 square foot Greenburgh home burning 900 gallons a season through an aging oil furnace.
Staying on oil, per year:
After converting to a cold-climate heat pump:
Your number depends on your actual gallons, your electric rate, and how well the system is sized, which is why the receipts-and-bill exercise beats any article, including this one.
Break-Even, With the State Carrying the Front End
Now the purchase side. But New York does not ask you to pay gross.
| Line | Amount |

| Break-even | ~4.7 years |
Income-eligible households do far better. The full program mechanics, including the participating-contractor rule that decides whether any of this money reaches you, are in the White Plains rebates guide.
What Oil Still Has Going for It
An honest comparison names the other side's real advantages.
The furnace is already paid for. If your unit is mid-life and healthy, converting is a choice, not an emergency. The math still favors switching, but the timing is yours. The worst moment to decide is during a no-heat call in January; the best is any month before that.
The known quantity. Your oil company knows your tank; your burner tech knows your basement. A conversion means one season of learning a new rhythm: steady, low-and-slow heat instead of the blast-and-coast cycle an oil furnace trained you to expect.
Hydronic distribution already works. If you have baseboard or radiator loops, your heat delivery is fine; the question is only what makes the heat. That shapes system choice and price, which is why the installation cost guide breaks ranges out by system type rather than pretending one number fits a Scarsdale prewar and a Hartsdale ranch alike.
None of this changes the direction of the math. It changes the timing, and the timing is legitimately yours.
The Decision, Compressed
The cold question is answered by the qualified list and a contractor who sizes to a cold night. The variable left is your house.
