Heat Pump Cooling Replacement on Long Island

Replacing Your AC? Consider a Smarter Upgrade

If your central air conditioner is nearing the end of its life, you have more options than simply installing another AC. A modern heat pump system can fully replace your air conditioner, delivering the same powerful cooling in summer — while also providing efficient heating in winter. Instead of investing in a single-purpose cooling system, many Long Island homeowners and businesses are choosing heat pumps for year-round comfort, lower energy costs, and major rebates.

Yes — Heat Pumps Cool Just as Well as Traditional AC

One of the most common questions we hear is whether a heat pump can cool as effectively as a standard air conditioner. The answer is absolutely.

Heat pumps use the same refrigeration technology as central AC systems. In cooling mode, they perform exactly like an air conditioner — removing heat and humidity from your space and delivering consistent, comfortable cooling even during Long Island’s hottest, most humid summer days.


Today’s systems feature:



  • High SEER2 efficiency ratings (often 16+ or higher)
  • Variable-speed compressors for even temperatures
  • Excellent humidity control for sticky summer conditions
  • Quieter operation than many older AC units

In many cases, heat pumps actually cool better and more evenly than older central air systems.

One System for Cooling and Heating

The difference — and the upgrade — is that a heat pump can reverse operation in colder months to provide heating as well. This means:


  • No separate furnace or boiler is required
  • One outdoor unit handles both seasons
  • Less equipment to maintain
  • Higher overall system efficiency

Cold-climate heat pumps installed by Cool Pro Mechanical are designed for New York weather and continue delivering reliable heat even when outdoor temperatures drop well below freezing.

The Home Comfort PLUS Program is PSEG Long Island’s primary rebate initiative designed to reduce energy usage and encourage cleaner, more efficient electric heating and cooling. The program focuses mainly on air-source heat pumps, including ducted systems and ductless mini-splits, which provide both heating and cooling using electricity instead of fossil fuels.



To qualify for rebates, installations must be completed by a PSEG-approved contractor — and Cool Pro Mechanical is proud to be one.

Lower Cooling Costs — Plus Major Rebates

 Heat pumps are significantly more efficient than older air conditioners because they move heat instead of generating it. When replacing an aging AC, many customers see cooling cost reductions of 20–30% or more.


Beyond monthly savings, incentives make the upgrade even more attractive:


  • PSEG Long Island rebates up to $5,000 for qualifying heat pump installations
  • Up to $11,000 available for income-qualified households
  • Federal tax credits up to $2,000 for heat pump systems
  • Optional 0% financing to reduce upfront cost

By combining rebates, tax credits, and efficiency savings, many customers pay less for a heat pump upgrade than they would for a standard AC replacement.
