  • Improvements must be made to all accessible ductwork in an existing duct system.
  • This program does not allow fuel switching. (Example: Central air conditioners must be replaced with central air conditioners and heat pumps must be replaced with heat pumps. converting from a central air conditioner, gas furnace, or gas pack to an electric heat pump does not qualify for the rebate.)
  • This program does not provide rebates for new equipment that does not replace old equipment of the same type. Ground source heat pumps do not qualify for rebates.

Frequently Asked Questions

Under the Bipartisan Budget Act of 2018, which was signed in February 2018, a number of tax credits for residential energy efficiency that had expired at the end of 2016 were renewed. Tax credits for non-business energy property are now available retroactively to purchases made through December 31, 2017. Learn more about available federal tax credits.

Yes, a licensed mechanical contractor must perform your HVAC equipment installation and ductwork improvement(s). We do not provide rebates for self-installed or DIY projects.

No, you must receive residential electric service from Dominion Energy South Carolina to be eligible for the EnergyWise Heating and Cooling rebate program. However, if you convert to natural gas heat or water heat, you may be eligible for a $200 bill credit from Dominion Energy SC. If you convert to a natural gas cooktop or logs, you may be eligible for a $50 bill credit. See available gas rebates.

All rebates are paid by check to the account holder.

The average processing time is 4-6 weeks. Please be aware that during peak heating and cooling seasons we receive a large volume of applications. To ensure your check will be delivered in a timely manner, please use the checklist provided with each application.

If the installed equipment does not match the removed equipment, this is called “fuel switching”. Fuel switching occurs when an old HVAC unit of a certain fuel type (electricity or gas) is replaced with a new unit that uses a different fuel type. (For example, if you replace an old gas unit with a new electric heat pump, this is considered fuel switching.) This rebate program does not apply to fuel switching improvements.

The Air-Conditioning, Heating and Refrigeration Institute (AHRI) is the most trusted source of performance certification for HVAC equipment. AHRI tests the performance of equipment and assigns a unique identifying number, which can then be used to look up performance information to include the SEER, EER and HSPF ratings. Your HVAC contractor should provide the AHRI number on your application.

Since our program follows ENERGY STAR® guidelines, we revised our minimum efficiency requirements to meet the ENERGY STAR® minimum efficiency level, which is now 15 SEER.

No. Ground source heat pumps are not eligible for a rebate. However, please consult your tax advisor for information regarding home improvement tax credits which may cover ground source heat pumps.
