If your heating and cooling system is more than ten years old or needs to be replaced, install an ENERGY STAR® -certified system to maximize energy savings.

Additional Details

You want your home to be comfortable year-round, and now comfort and cost can be balanced with the selection of an energy-efficient heating and cooling system for your home.

Selecting the right system, and size of system, for your home has never been more important. According to the U.S. Environmental Protection Agency, heating and cooling account for up to 56 percent of energy used in a typical U.S. home, making it the largest energy expense for most homes.

Fortunately, now there are a wide variety of energy-efficient systems available to heat and cool your home. In addition, many heating and cooling systems have supporting equipment in common, such as thermostats and ducts, which provide opportunities for more energy savings. Finding the most energy-efficient system is easy – just look for the ENERGY STAR®.  An ENERGY STAR-certified central air conditioner is 15 percent more efficient than a standard system. Those savings can add up.

How We Can Help

We help make it affordable to upgrade your heating and cooling system with rebates of $200 - or even $500 per ton up to two systems per home. Rebates apply to qualifying ENERGY STAR central air conditioning or heat pump systems.

Energy-efficient heating and cooling equipment will save you energy and money.

Call 877-WISE-USE (877-947-3873) for more information. 

Rebate applications for 2020 rebates are being accepted and processed for payment. Please submit your 2020 rebate within the prescribed timeframe on the rebate form. Please contact Eversource or United Illuminating at 877-WISE-USE with questions.

There are a few kinds of HVAC systems you could have installed in your home which are dependent on where you live, square footage, construction type and cost. Listed below are the two types available for the rebate.

  • A split HVAC system is comprised of multiple sections, an indoor coil section in the ductwork and an outdoor coil section (compressor/condenser) installed on the outside of the home. Inside the home (attic, basement, closet) there may be a combined fan and air conditioning coil in one box or separate coil and fan sections which can house a gas or oil heating furnace. Note that the installed system must be a matched assembly to qualify for rebate (the two or three components must be matched; more information can be found on the AHRI Directory). Most often, all sections would require replacement to ensure the best efficiency.

Residential customers of Eversource and UI are eligible for the rebates.

Equipment must be installed by a licensed contractor in the service territory of the participating electric utility.

A rebate of $1,000 per ton is also available in addition to the up to $500 rebate if your home is an electric heated home and you participate in Home Energy Solutions or if your home is heated by oil or propane and you qualify to participate in the Home Energy Solutions Heat Pump Pilot. Please refer to the rebate form you received during your appointment to apply for this Home Energy Solutions rebate.

Qualifying Systems

Qualifying systems are electric central air conditioning and ducted air source heat pump split systems of matched assembly, in which both the condenser unit and the evaporator coil are installed simultaneously. A matched assembly is a model combination that is listed in the AHRI Directory of Certified Equipment. A matched assembly must also include the air handler, furnace or other component that is used to determine the rating according to ANSI/AHRI STANDARD 210/240-2008. To see a list of qualifying units, download the CT Qualified Products List (QPL).

Note: Ducted air source heat pump split system sold prior to April 1, 2021 will receive the corresponding tier rebate if it meets the qualifying SEER and HSPF criteria, the minimum heating capacity ratio will be required.

AHRI – Air Conditioning Heating and Refrigeration Institute. All equipment must be rated in the AHRI Air Conditioners and Air Conditioner Coils or Heat Pumps and Heat Pump Coils Directories. Both can be found online on the AHRI website.
2 SEER – Seasonal Energy Efficiency Ratio
3 HSPF – Heating and Seasonal Performance Factor
4 Heating Capacity Ratio requirement is the minimum equipment performance for heating capacity at 17º F, divided by the heating capacity at 47º F, expressed as a percentage.
*Actual tons are calculated based on AHRI cooling capacity divided by 12,000 BTUs.  Rebate amount based on actual tons.  Up to two systems per home.
**To qualify, you must be an electric resistance heat customer who has also participated in a Home Energy Solutions assessment or a customer converting from fuel oil or propane who has also participated in the Home Energy Solutions Heat Pump Pilot prior to the heat pump installation.
