Heating, Ventilation, and Air Conditioning

ENERGY STAR® Central Air Conditioner and Central Heat Pump Rebates

Up to $1,500 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.

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 and sizing the right 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 can make it affordable to upgrade your heating and cooling system with mail-in rebates of $200 per unit for qualifying central air conditioning and $500 per ton* for qualifying central heat pump systems - provided by the Connecticut Energy Efficiency Fund.

Differentiating High Efficiency HVAC Systems

There are various 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.

How to Apply for a Rebate

Step 1 - Review the rebate application for details on qualifying heat pump and air conditioning systems. Rebates of $200 per unit for central air conditioners and $500 per ton* for central heat pump systems, up to $15,000 per home, are offered for high-efficiency central air conditioners or central air source heat pump split systems.

Step 2 - Contact your heating and cooling contractor about what system is right for you.

Step 3 - Have your qualifying unit installed.

Step 4 - Save time and money - click here to apply for a rebate and submit the required documentation online. Rebates are per-unit fixed amounts, paid directly to you, the consumer, or the installation contractor. If you wish, you have the option to mail in the completed application and supporting documentation instead. See the application document for further details.

Home Energy Solutions Incentives

A rebate of $1,000 per ton* is also available in addition to these rebates. If you have electric resistance heat and participate in Home Energy Solutions, please refer to the rebate form you received during your service. To apply for this Home Energy Solutions rebate online, click here. If you heat with oil or propane, you qualify to participate in the Home Energy Solutions Heat Pump Pilot. Please complete this eligibility application.

Who Is Eligible For a Rebate and Qualifying Systems

Residential customers of UI are eligible to receive incentives on the systems shown below. Equipment must be installed by a licensed contractor in the UI service territory.

Qualifying Systems

Qualifying systems are electric central air conditioning and central 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, and other components that are used to determine the rating according to ANSI/AHRI STANDARD 210/240-2008. To see a list of qualifying units, visit the CT Qualified Products List (QPL) at EnergizeCT.com.

Note: Central air source heat pump split systems 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 as of April 1, 2021.

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 HSPF – Heating and Seasonal Performance Factor

4 EER – Energy Efficiency Ratio

5 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 the actual tons. Up to $15,000 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 for the Heat Pump Pilot Program.
