Heat pumps vs. oil furnace heating: What’s better in 2026?

For many of us, heating our homes in the winter isn’t optional—it’s essential. And the past week has been a sharp reminder of something homeowners have learned the hard way before: Home heating oil prices don’t answer to your thermostat. The U.S.-Iran conflict has already sent oil prices surging—and when crude goes up, home heating oil isn’t far behind.

If you currently heat your home with oil and you’re starting to wonder whether there’s a smarter way, you’re probably weighing your options. You could stick with the oil furnace you know, or switch to the heat pump everyone seems to be talking about. The timing of that decision just got a lot more loaded.

Both systems will keep you warm, but they work very differently—and one of them insulates you from volatile global energy markets. The right choice depends on your home, your budget, and how you want to heat for the next 20-plus years. We’ll break down the real differences—upfront costs, efficiency, operating expenses, and maintenance—so you can make a confident decision.

Heat pumps

Heat pumps have quietly become one of the most popular home heating and cooling upgrades in the country. For the past four years, they've been the most-shipped heating appliance to the U.S., outselling gas and oil furnaces—according to shipment data from the Air-Conditioning, Heating, and Refrigeration Institute.

So what's driving the surge? Efficiency, mostly.

Instead of burning fuel to generate heat, heat pumps work by using electricity to move heat from outdoor air into your home (yes, even in cold weather, down to -15°F with modern cold-climate models). It's the same principle as air conditioning, just run in reverse. The result: one system that heats in winter and cools in summer.

What sets heat pumps apart is their efficiency. For every unit of electricity they consume, they deliver two to four units of heat—an efficiency rate that no combustion-based system can match. Heat pumps can connect to your existing ductwork or, if you don't have ducts, use wall-mounted ductless mini-splits for room-by-room control.

Oil furnaces

Around 4.79 million U.S. households use heating oil as their primary fuel, and roughly 82% of them are in the Northeast—areas that historically lacked access to natural gas pipelines but still face long, cold winters.

Oil furnaces burn heating oil to warm air that's distributed through ductwork—a familiar, reliable setup that's heated homes in cold climates for generations.

The main catch: oil is a fossil fuel that has to be delivered to a tank on your property. Most tanks hold up to 240 gallons of usable oil, and at around 32°F, a typical system burns about 6.5 gallons per day—so expect at least one delivery per month during a cold winter. Prices swing with crude oil markets, which makes budgeting unpredictable from year to year.

Heat pump costs

Heat pumps cost $15,393 on average before incentives, according to 2026 EnergySage Marketplace data. However, the price can range widely—between $14,000 and $26,000—based mainly on where you live and the type, size, and complexity of your heat pump system.

If you have existing, functional ductwork, ducted air-source heat pumps are generally less expensive overall because one outdoor unit is usually enough to heat a typical house. The average cost for a ducted heat pump system is $14,529 before incentives.

For homes without ducts, ductless mini-split systems may be cheaper to install per unit and can provide multiple zones of temperature control using independent indoor heat exchangers. However, larger homes that install three or more zones will likely see higher overall costs than those installing a single air-source system because of the additional units and labor involved.

In some cases, particularly in older homes, electrical upgrades to breaker panels or meter connections may be necessary for heat pumps to function properly, which can increase installation costs. But also remember that available clean energy incentives can knock as much as $10,000 off the price, depending on where you live.

Oil furnace costs

Oil furnaces can cost between $6,400 and $9,200 to install, with an average cost of $7,400. A new oil furnace can usually be fitted to existing ducts within a home, but additional modifications may be required to allow the oil tank to be regularly refilled, which can add to the cost.

Verdict: Oil furnaces may be cheaper to install...but there's a catch

You'll typically pay more to install a heat pump system than an oil heating system. But once installed, heat pumps are significantly more efficient than oil heat and don’t require regular refueling (more on that in the next section). Plus, remember: with a heat pump, you're getting both heating and cooling from one system, rather than installing an oil furnace and then having to install a separate AC.

Also, treat all these cost figures as estimates—unique aspects of your home may require additional work or materials to properly install heat pumps or oil heating, which could increase the price. It’s best to get multiple quotes from different HVAC installers before deciding based on price.

Heat pumps

The cost to operate a heat pump system depends on how much electrical energy is needed to heat your home. Consumption depends on many factors, including what electricity costs in your region and what temperature you like to maintain inside your home.

Heat pumps become less efficient as the outdoor temperature drops. In ideal conditions, the average heat pump can produce up to 400% more heat energy than it consumes in electricity. That rate drops to around 250% at 32°F, and 100% or less at 0°F. Most modern heat pumps can still effectively heat your home at temperatures well below freezing, with cold-climate heat pumps able to heat down to -15°F, but system efficiency won’t be optimal.

If you live in a region with average daily temperatures below freezing for more than a few days a year, the overall efficiency of a heat pump system in the winter could be as low as 200%—which is still better than oil furnaces' efficiency.

Oil furnaces

The cost to operate an oil furnace also depends on several factors, including the price of heating oil, the efficiency of your furnace, and the average outside temperature. Oil furnaces average about 85% efficiency, making them significantly less efficient than a heat pump. However, unlike heat pumps, the efficiency doesn’t change based on the outside temperature. Oil furnaces are located inside, away from the elements, and don’t function by pulling warmth from the air. 

Similar to a heat pump, lower temperatures mean your furnace will use more energy to maintain a warm interior. Homes that regularly see average temperatures below freezing will spend more on oil heating because they have to burn more. You can estimate oil furnace operating costs by multiplying the size of the tank in gallons by the average cost per gallon of an oil delivery. 

Verdict: Heat pumps win on efficiency

The cost of heating your home with heat pumps or oil heat depends on several factors, including the price of electricity, the price of heating oil, the average outdoor temperature, and how warm you keep your home. Per unit of energy consumed, though, heat pumps will always be more efficient than oil heating, even in cold climates.

Heat pumps

Heat pumps are relatively low-maintenance. An annual professional tune-up is recommended, along with filter changes every three to six months. If you have mini-splits, the filters built into the indoor units need to be cleaned or swapped regularly too. Outside of that, there's no fuel system to monitor and no delivery to schedule.

Oil furnaces

Oil furnaces need more consistent upkeep. In addition to annual professional servicing, you'll want regular nozzle inspections and carbon monoxide checks. You'll also need to keep an eye on your tank level throughout the season and schedule deliveries before you run low, which can be stressful during cold snaps when demand spikes and delivery windows stretch out.

The verdict: Heat pumps are lower maintenance

Both systems require annual servicing, but oil furnaces carry more ongoing maintenance responsibility. Heat pumps are simpler to maintain and eliminate the logistics of fuel delivery entirely.

Oil furnaces

Heat pumps and oil furnaces both get the job done when the temperature drops. But they represent very different bets on the future.

Oil heating has worked reliably for generations, and in areas with low oil prices and cheap contractor access, it remains a familiar choice. But between fuel price volatility, relatively low efficiency, and the ongoing maintenance of a tank-based delivery system, oil heat comes with real costs—financial and otherwise—that add up over time.

Heat pumps cost more to install, but their efficiency advantage means they typically pay that difference back. They also bring year-round comfort (no separate AC needed), more predictable operating costs, and compatibility with solar if you want to take it a step further.

Some homeowners hedge their bets with a hybrid system—a heat pump for most of the year, with their existing oil furnace as backup on the coldest nights. For certain households and climates, that combination offers the best of both worlds.
