ENERGY STAR® Central Air Conditioner or Heat Pump Rebate

Rebates of Up to $500 for Qualifying Systems
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.

High-Efficiency Heating & Cooling

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.

Now is also the time to make sure that you get the best performance from your new system. We suggest you also participate in the Quality Installation and Verification (QIV) Program. In addition to a list of qualified contractors, the QIV program offers additional rebates of $100 to $500 for qualifying systems.

How We Can Help

We help make it affordable to upgrade your heating and cooling system with rebates of $250 - or even $500 - provided by the Connecticut Energy Efficiency Fund. 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.

Differentiating High Efficiency HVAC Systems

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.
  • A package system contains all components in one box (compressor, condenser, fan) and is typically found installed outside the home, in some cases on the roof and ducted into the home.

Step 2 - Contact your heating and cooling contractor about what system is right for you. To make sure that you get the best performance from your new system, we suggest you also participate in the Quality Installation and Verification (QIV) Program. In addition to a list of qualified contractors, the QIV program offers rebates of $100 to $500 for qualifying systems. That is in addition to the $250 or $500 rebate offered for choosing a high-efficiency AC or Heat Pump or in addition to the $600 for choosing a natural gas warm air furnace.

Step 3 - Have your qualifying unit installed.

Step 4 - Submit your rebate application along with required documentation. Rebates are per-unit fixed amounts, paid directly to you, the consumer.

Who Is Eligible For a Rebate and Qualifying Systems

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.

Qualifying Systems

Qualifying systems are electric central air conditioning and air-source heat pump 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.

Eligible Equipment TypeMinimum Efficiency For RebateRebate Per System
AHRI1 Rated Central Air Conditioning Split System16 SEER2 / 12.5 EER3$250
AHRI Rated Air Source Heat Pump Split Systems16 SEER / 12.5 EER / 10 HSPF4$500 

1 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 EER – Energy Efficiency Ratio
4 HSPF – Heating and Seasonal Performance Factor

Visit our Ductless Split Heat Pump or Geothermal Heat Pumps pages for incentive information for those systems.

If you are a Connecticut resident and are not served by one of the utilities listed above, please visit your municipal utility’s website to see what energy efficiency programs are available to you.

Energy Efficiency & Renewable Energy Tax Credits

Did you know you might be able to take advantage of federal income tax incentives for energy-efficient and renewable energy home improvements? Congress first passed the incentives in 2005 as part of the Energy Policy Act of 2005 and has amended them several times since then.

Current incentives expire December 31, 2016. The incentives fall into two categories. Be sure to review both to maximize your incentive.

  • Renewable energy sources like geothermal, solar, wind and others are covered under Residential Energy Efficient Property Credit (Part I). You may be able to take a credit of 30% of your qualified costs.
  • Energy efficiency improvements like insulation, windows, HVAC and more are covered under Nonbusiness Energy Property Credit (Part II). Credits for 10% of cost, up to $500 or a specific amount from $50-$300 may be available.
