A heat pump proposal isn’t automatically a rebate-eligible proposal. Before signing, homeowners need to distinguish the 2026 whole-home incentive from Rate 580’s electric delivery discount and the federal tax credit that ended for 2026 installations.
For Nassau County homeowners comparing residential HVAC options, eligibility depends on household income or address status, system design, equipment selection, and the installing contractor.
Current PSEG Long Island Whole-Home Heat Pump Rebate Tiers
For 2026, the Home Comfort Program offers different rebate amounts for qualifying single-family projects. The applicable tier isn’t based on the heat pump’s price alone.
- Low-income households: $7,500 for households below 60% of area median income.
- Moderate-income households: $5,000 for households below 80% of area median income.
- Market-rate households in a Disadvantaged Community: $5,000.
- Other market-rate households: $4,000.
Area median income, often called AMI, is an income benchmark that varies by household size. In 2026, the maximum gross annual income shown for a one-person household is $69,263 at the 60% AMI level and $92,350 at the 80% AMI level. Larger households have different limits, so use the program’s household-size guidelines rather than applying the one-person figures to every home.
Disadvantaged Community status is based on the census tract containing the property, not a general community name. New York’s mapping tool can show whether a specific address is in a designated tract. The program also lists a separate $250 per-project contractor incentive, which isn’t part of the homeowner’s rebate.
System Requirements That Determine Rebate Eligibility
The incentive is intended for a heat pump designed to carry the home’s heating needs, not simply supplement one room or floor. That distinction should shape the questions you ask before choosing equipment.
A qualifying system must meet 100% to 120% of the dwelling’s entire heating load. The contractor must use a Manual J calculation, a room-by-room heating and cooling load assessment based on factors such as the home’s size, insulation, and windows. A rule-of-thumb equipment size isn’t a substitute for a Manual J calculation.
Eligible equipment must be purchased from and installed by a participating PSEG Home Comfort Partner. For a cold-climate air-source heat pump, meaning a system designed to provide heat in cold outdoor conditions, the proposed equipment must appear on the NEEP Cold Climate Air Source Heat Pump Specification Product Listing.
Ask for these details in writing before assuming a project qualifies:
- The outdoor and indoor equipment model numbers.
- The Manual J heating-load result and the proposed system’s percentage of that load.
- Whether the design is intended to heat the entire home.
- Confirmation of the installing contractor’s current PSEG Home Comfort Partner status.
These details are more useful than broad language such as “rebate-ready.” They also help you compare proposals that recommend different equipment capacities or retain different parts of an existing heating system.
Keeping a Furnace or Boiler Changes the Requirements
Keeping an existing furnace or boiler doesn’t automatically prevent a qualifying heat pump project, but it changes how the system must operate. Under the program requirements, the heat pump must be the primary heating system and the fossil-fuel system must remain secondary.
This arrangement requires a dual-fuel thermostat or integrated controls unless the existing fossil-fuel system is removed. These controls coordinate the two heat sources so the heat pump serves as the primary system and the backup equipment operates under the required settings. Make sure the proposal identifies the control approach, not just the equipment being left in place.
Rate 580 Is Separate from the Rebate
This electric-rate program isn’t an upfront heat pump incentive. Customers whose heat pump is the home’s primary heat source may be eligible for PSEG Long Island’s Residential Electric Heating Rate 580, which provides a 40% energy delivery charge discount from October through May on monthly usage above 400 kWh.
Eligibility for the rate doesn’t create a rebate, and receiving a project incentive doesn’t establish eligibility for the rate. Treat them as separate parts of the financial picture: one reduces the project cost, while the other affects qualifying winter electric bills.
Federal Credit & Heat Pump Water Heater Deadlines
The former federal heat pump credit isn’t available for a 2026 installation. The Energy Efficient Home Improvement Credit, which allowed up to $2,000 per year for qualifying heat pumps, doesn’t apply to property placed in service after December 31, 2025.
Homeowners who installed qualifying equipment during 2025 may still claim the former credit on a 2025 tax return, subject to the applicable tax rules. It shouldn’t be included in the projected savings for a heat pump installed in 2026.
The space-conditioning incentive shouldn’t be confused with the separate electric heat pump water heater offer. A whole-home space-conditioning heat pump heats and cools the home, while a heat pump water heater produces domestic hot water. They’re different projects with different requirements.
For the separate electric heat pump water heater rebate, the utility requires purchase and installation on or after January 1, 2026, with the application postmarked no later than December 31, 2026. That rebate can’t exceed 50% of the retail purchase price paid. This water-heater date isn’t a stated deadline for the space-conditioning rebate, so don’t apply it to a heating and cooling project without reviewing the relevant program terms.
Planning the Heat Pump Project Beyond the Rebate
A rebate can reduce the initial project cost, but it doesn’t replace sound equipment selection or routine care. Because a heat pump handles both heating and cooling, appropriate controls, airflow, and seasonal maintenance all affect its performance.
Annual service before peak winter or summer demand can identify maintenance needs on a planned schedule. Our Residential Membership Plan includes two annual maintenance appointments, scheduled for fall and spring, along with priority scheduling and discounts on repair services.
