Neither fuel source wins for every house when you compare heating oil vs. natural gas. It’s true that natural gas usually costs less to run, especially with current heating oil prices. However, oil is the practical choice throughout much of Long Island, where switching to gas could be a five-figure decision.
Soundview HVAC is a licensed heating and cooling specialist offering gas and oil heating installations throughout Long Island. Let’s look at how oil and gas differ, the benefits on both sides, and help you make the best decision for the winters to come.
Key Takeaways
- Gas is usually cheaper for residential heating but isn’t available everywhere on Long Island.
- Switching can cost a significant amount, adding between $8,000 and $20,000 to your project.
- Check street availability before comparing anything else.
Before You Continue: Find Out if Gas is Available at Your Location
Before you even consider a Long Island heating installation with a move away from heating oil, you need to determine if gas is available on your street.
The National Grid Service Map for New York is a direct resource you can use if you don’t already have gas at home. If your street isn’t served, then oil is the best fuel source for a furnace-based heating system.
How Heating Oil and Gas Compare for Heating Installation on Long Island
For homeowners in Suffolk and Nassau Counties, the comparison between heating oil vs. natural gas comes down to some practical points.
- Running Cost: Gas is generally the cheaper way to heat your home. Oil prices swing much harder. For example, in September 2026, the heating oil price average was up 70.1% on Long Island compared to the same period in 2025. Depending on prices, gas can be 40% to 50% cheaper than heating oil when comparing heating in the same space.
- Availability: Parts of Long Island simply don’t have gas infrastructure. The split is largely east to west, with gas becoming less common moving deeper from Nassau into Suffolk County. Unincorporated villages, some coastal areas, rural areas, and the East End are the most likely to lack gas infrastructure away from major thoroughfares.
- Convenience: Gas arrives from a pipeline, while heating oil is delivered by a truck and stored in your own tank. Gas is always on, while oil requires that you watch the tank level and keep up with deliveries.
- Cleanliness: Oil burns cleaner than it used to, thanks to a biodiesel blend of around 5%. If you’re concerned about environmental impact, modern systems, gas or oil, are as clean as they can be with current technology.
- Equipment: Modern units for either fuel beat a 20-year-old system by a significant margin, often by up to 30%. Even if you stick with heating oil, a new furnace installed in 2026 will cost less to run than your old system.
If Gas is Much Cheaper Than Heating Oil, What’s the Catch?
The catch is that gas being cheaper only tells part of the story. There are additional, non-negotiable costs if you convert your home from fuel oil to gas.
With oil prices surging and highly volatile in 2026, this winter could be one of the costliest ever for heating oil deliveries. If this is the case, why doesn’t everyone switch to gas?
Availability is the major factor, but even when a new gas line is possible, there are hidden costs.
- Converting a home to connect to the gas grid can cost from $8,000 to $20,000 in most cases.
- The cost includes the gas hook-up, removal of an old oil tank, and boiler or furnace replacement.
This leaves many homeowners to consider alternatives beyond gas heating.
Long Island Heating Installation Options
If gas conversion is impractical or too expensive in your case, you have two practical options:
- Stay on oil heating. Prices will continue to fluctuate for the foreseeable future, but a high-efficiency furnace can help to ease the financial pressure. You will usually find that a new heating installation is more affordable to run than the old unit you replace.
- Install an electric heat pump designed for cold climates. This is a complete break from a fuel-based furnace, but it makes sense. High-efficiency heat pumps beat both oil and gas on raw energy efficiency. You will spend less money to heat your home compared to oil, and you won’t need to store fuel or worry about combustion in your home.
Heat pumps are popular because they’re now strong enough for Long Island’s climate, and because there are direct incentives available.
Saving Money on a Heat Pump Installation
The NYS Clean Heat Program offers incentives for homes that convert from fuel-based systems to electrical heating.
- Most households can qualify for a Clean Heat rebate of $4,000.
- Some income-qualified households can qualify for rebates of up to $7,500.
Soundview Heat and Air Conditioning is a Participating Contractor in the Clean Heat Program. The rebate will be applied directly as a discount on your installation.
