Available Rebate Types

After your Home Performance with ENERGY STAR® assessment is complete, your program-approved contractor will recommend a variety of energy efficiency improvements for your home that may qualify for significant rebates.


Excessive air leaks allow costly conditioned air to escape from your home. Your contractor or Energy Advisor may recommend sealing air leaks to keep your conditioned air in your home and keep the outside air out.  Many older homes are poorly insulated or have no insulation at all. Properly installed insulation provides more even temperatures throughout the house and results in a quieter, more comfortable living environment that is less costly to heat and cool.


Ventilation, or the exchange of indoor air with outdoor air, is critical to reducing indoor air pollutants, moisture and odors in your home. Without proper ventilation, contaminants such as formaldehyde or other volatile organic compounds (VOCs), and radon can cause health problems, while excess moisture can lead to mold growth and physical damage to your home. To ensure the health and safety of the occupants, the program requires mechanical ventilation to be installed as deemed appropriate by your participating contractor.


Many homes have leaky ductwork and poor airflow resulting in uncomfortable rooms. Your contractor or Energy Advisor may recommend sealing and/or insulating your home’s air duct distribution system. Sealing and/or insulating ductwork spaces can reduce energy usage and increase your home’s overall comfort.


If your heat pump, furnace or air conditioner is more than 10 years old, your contractor or Energy Advisor may recommend replacing it with a properly-sized unit that is ENERGY STAR® certified. When installed correctly, high-efficiency units can help you save on heating and cooling costs. They also can make your home more comfortable year-round by providing more consistent indoor temperatures and better humidity control.


Your contractor or Energy Advisor will test the combustion equipment in your home, such as your furnace and hot water heater, to ensure that they operate and vent properly. In addition, the contractor will conduct a carbon monoxide reading on natural gas ovens and other areas to further test the safety of your home.


During the assessment your contractor or Energy Advisor will install up to $200 worth of energy-saving products in your home at no additional cost including:

  • Energy-efficient light bulbs, with options formidable, candelabra, globe and LED light bulbs
  • Faucet aerators
  • Efficient-flow fixed shower heads
  • SmartStart™ shower valve
  • Water heater pipe insulation (Installed on first four feet of hot water pipe only)

Rebate Eligible Measures

Rebates are available for property owners, including rental property owners, who complete an energy audit conducted by a program-approved auditor/contractor. The property owner and their selected program-approved auditor/contractor must review the energy audit report which details a prioritized list of energy improvements/upgrades. After this review, the selected program-approved auditor/contractor will make a rebate reservation on behalf of the property owner to secure the rebates for the selected rebate-eligible work. Property owner must receive a rebate reservation confirmation before beginning any work.

  • Rebates are capped at 50% of the total installed cost up to the incentive level indicated; whichever is lower.
  • Rebates are subject to change and are not guaranteed until a rebate reservation is confirmed.
  • Rebate payments can take up to six weeks to be processed for payment to either the homeowner or the contractor.
  • Excludes geothermal heat pumps. Visit dnrec.delaware.gov for more information on available geothermal heat pump rebates through Delaware’s Green Energy Program.
