Modernizing New York State's existing buildings requires innovative solutions and the ability to scale the adoption of clean, energy efficient technologies. Room heat pumps offer a practical pathway to upgrade thousands of multifamily buildings across New York.
Through strategic partnerships with manufacturers and building owners, NYSERDA is accelerating the development and deployment of these technologies while collecting critical performance data to build market confidence and drive widespread adoption.

Key Program Benefits
NYSERDA is investing in product development and field demonstrations to ensure room heat pumps perform reliably in New York's diverse climate.
Product development. NYSERDA has vetted and collaborated with room heat pump manufacturers to identify products that have been developed to meet New York building owner’s rigorous performance and quality standards.
Field demonstrations and real-world performance data collection. Once a product is ready, NYSERDA is connecting building owners with these qualified manufacturers to host subsidized field demonstrations that include collecting real-world performance data.
Third-party testing. NYSERDA is collaborating with the Syracuse University Center of Excellence in Environmental and Energy Systems (SyracuseCoE) to test the qualified room heat pump products to better understand the true, seasonal cost of operation in New York’s climate conditions.
Program Offerings for Multifamily Building Owners
NYSERDA provides funding to lower the cost of installing room heat pumps for New York State multifamily building owners.
| Window Heat Pump Field Demonstration Incentives |
| $2,250 per window heat pump installed in low- to moderate-income dwellings. |
| $1,500 per window heat pump installed in market-rate dwellings. |
| Incentives are capped at 100% of total project cost (material cost + installation cost, and the total project incentive cap is $500,000. |
| Through-Wall Heat Pump Field Demonstration Incentives |
| Up to $20,000 per apartment for through-wall heat pump installation and demonstration. |
| Capped at 100% of total project cost (material cost, installation cost, building make-ready work) |
Why Choose Room Heat Pumps?
Room heat pumps have the following advantages over other multifamily heating and cooling solutions:
-
Lower upfront cost and installation complexity As a packaged product, there is no refrigerant piping, limited electrical upgrades needed.
-
Faster installation timeline Little design needed for each project; faster install.
-
Minimal resident disruption during installation
-
More consistent, comfortable outcomes for customers (temperature control, potential for improved indoor air quality throughout all seasons).

What Are Room Heat Pumps?
Room heat pumps are plug-and-play heating and cooling solutions that minimize electrical service or building electrical infrastructure upgrades, which can mean substantial cost savings. Unlike central systems that require extensive ductwork or mini-splits that need ample space for outdoor compressors and refrigerant lines, room heat pumps install directly into existing window or through-wall openings—making them ideal for retrofits to provide both heating and cooling from one piece of equipment.
The Room Heat Pump Program supports two categories of room heat pump products:
Window Heat Pumps
Window heat pumps are designed to replace traditional window air conditioners, transforming cooling-only units into year-round heating and cooling solutions. These innovative products fit standard window openings and offer an accessible entry point for energy efficient retrofits.
Through-Wall Heat Pumps
Through-wall heat pumps are designed for buildings with through-wall sleeves and can provide efficient heating and cooling without major infrastructure changes. They replace existing equipment in three categories:

Through-Wall Heat Pumps
Category 1: Standard-size packaged terminal air conditioning (PTAC)
Room heat pumps designed to replace PTACs in standard-size wall sleeves, typically measuring 16” high and 42” wide.
Category 2: PTAC in hydronic cabinets
Room heat pumps designed to replace PTACs in hydronic heat cabinets. Existing hydronic PTACs provide air conditioning while heating is provided by a central hydronic system. This category of heat pumps will provide both cooling and heating without relying on the central system.
