Long Island homeowners have access to one of the best HVAC incentive stacks in the country right now, but the programs are confusing — different agencies, different qualifying equipment, different paperwork. Here's how the two big ones actually work, and how to combine them on a single install.
PSEG Long Island — Home Comfort program
PSEG Long Island offers rebates to residential customers who upgrade to qualifying high-efficiency heat pumps, ductless systems, and (in some program years) central AC. The rebate amount depends on the equipment type, efficiency rating, and capacity. PSEG updates the program annually, so amounts and qualifying models change.
How the money reaches you
PSEG Long Island sets how each rebate is paid — for example, directly to the homeowner after installation or as a credit on the invoice — along with the installer requirements for each incentive tier. Those rules change by program year, so read the current program terms before you sign.
NYSERDA Clean Heat
NYSERDA's Clean Heat program is the statewide push to electrify home heating. The incentive is calculated per ton of heating capacity for qualifying air-source and ground-source heat pumps. Eligibility, incentive amounts, and how the money is paid are all set by NYSERDA and can change from one program year to the next.
Who qualifies
- Residential property in New York State (Long Island qualifies).
- Qualifying ENERGY STAR cold-climate heat pump.
- Proper Manual J load calculation and AHRI-matched equipment.
- An installer that meets NYSERDA's current contractor requirements — confirm with NYSERDA before you sign.
The federal tax credit (25C) ended after 2025
Through the end of 2025, the federal 25C Energy Efficient Home Improvement Credit added up to $2,000 in tax savings on qualifying heat pumps. That credit ended for installations placed in service after December 31, 2025, so we no longer promise it. The PSEG Long Island and NYSERDA programs above are current, and they remain the incentives that matter for Long Island installs.
Can you stack PSEG and NYSERDA?
Yes — PSEG Long Island rebates and NYSERDA Clean Heat incentives are designed to stack on a single qualifying heat pump install. The PSEG rebate and the NYSERDA incentive both lower the net cost, and the combined effect on a typical whole-home heat pump install on Long Island is often thousands of dollars off the sticker price.
