A boiler replacement on Long Island typically costs between $5,500 and $15,000 depending on the type of boiler, brand, and complexity of the installation. That is a significant expense for most families. The good news is that you do not have to pay the full amount upfront. We offer flexible financing through Wisetack, and there are several government programs, utility rebates, and tax credits that can reduce your out-of-pocket cost significantly.
This guide covers every financing option available to Long Island homeowners, including our pay-over-time program, New York State assistance programs, National Grid and PSEG Long Island rebates, and federal tax credits for high-efficiency equipment. For a full breakdown of boiler replacement costs, see our cost guide.

Many Long Island homeowners find that a fixed-term financing plan through Wisetack is more affordable and predictable than putting a boiler on a credit card.
National Grid Rebates
If your home is served by National Grid for natural gas, you may qualify for rebates on high-efficiency gas boilers. National Grid offers incentives for ENERGY STAR certified equipment with an AFUE rating of 95% or higher. Rebate amounts change periodically, so we verify the current available amount at the time of your estimate. These rebates are applied directly to reduce your project cost and can be combined with Wisetack financing on the remaining balance.
For more details on available National Grid rebates, see our National Grid boiler rebates guide.
PSEG Long Island Energy Efficiency Programs
PSEG Long Island serves all of Long Island for electric service and offers several energy efficiency programs that can indirectly help with boiler replacement costs. While PSEG does not directly rebate gas or oil boilers (they are an electric utility), their home energy assessment program can identify insulation, air sealing, and other improvements that reduce your overall heating load. This means your new boiler may be smaller and less expensive. PSEG also offers rebates on heat pump systems for homeowners considering an electric alternative to their boiler.
HEAP Heating Equipment Assistance
New York State HEAP
The Home Energy Assistance Program (HEAP) is a federally funded program administered by New York State that helps eligible low-income households with heating costs. The HEAP Heating Equipment Repair and Replacement benefit can cover the cost of replacing a broken or unsafe heating system, including boilers.
Eligibility: Household income must be at or below the current HEAP income guidelines, which are based on household size. For the 2025-2026 program year, a single-person household in Nassau or Suffolk County generally needs an income at or below approximately 60% of the state median income. Income thresholds increase with household size.
What is covered: HEAP can pay for a new boiler, installation labor, and related work such as chimney lining or venting modifications. The amount of assistance varies based on available funding. Applications are submitted through your local Department of Social Services.
If you believe you may qualify for HEAP assistance, let us know during your free estimate and we can help guide you through the process.
Federal Tax Credits
Inflation Reduction Act Tax Credits
The Inflation Reduction Act (IRA) provides federal tax credits for qualifying high-efficiency heating equipment installed in your primary residence. For boilers, this applies to ENERGY STAR certified natural gas boilers with an AFUE of 95% or higher.
Credit amount: Up to 30% of the cost of the equipment and installation, capped at $600 for natural gas boilers. For heat pump systems, the credit is up to $2,000.
How it works: The tax credit is claimed on your federal income tax return for the year the equipment is installed. It is a dollar-for-dollar reduction in your tax liability, not just a deduction. You will need the manufacturer certification statement and your installation receipt. Consult your tax professional for specific eligibility.
These tax credits can be combined with both utility rebates and Wisetack financing, effectively stacking multiple savings programs on a single boiler replacement project.
Stacking Your Savings
The most effective approach for Long Island homeowners is to combine multiple programs. Here is an example of how the numbers can work together on a high-efficiency gas boiler replacement:
Total Installed Cost
Example: $9,000 for a 95%+ AFUE gas condensing boiler installed.
National Grid Rebate
Instant rebate reducing the price. Amount varies by program year.
Federal Tax Credit
Up to $600 back on your tax return (30% of cost, capped at $600).
Wisetack Financing
Finance the remaining balance at 0% to 35.9% APR over 3 to 120 months. No hidden fees.
The rebate reduces your upfront cost, the tax credit gives you money back the following year, and Wisetack spreads the remaining balance into manageable monthly payments. This combination makes a high-efficiency boiler replacement significantly more accessible.
