Insulation upgrades are easy – and they pay off
Over time, insulation tends to settle, becoming thinner and less effective. Improving your insulation is an easy, cost-effective home improvement that pays off in greater comfort and lower bills.
The Home Energy Check is a free evaluation of your home's energy efficiency. You'll receive:
You can complete the check in less than 15 minutes over the phone or online. You may also schedule an in-home check.
If you have completed a free Home Energy Check and received a qualifying recommendation within the past 24 months, simply ask us for a list of prequalified contractors in your area. You may fill out the form in the link below or call us.
All insulation has an R-value that states how deep it is and how well it insulates. The following guide can help you estimate your rebate.
If your insulation is less than R-12:
If your insulation is between R-12 and R-15:
Certain guidelines and restrictions apply:
If you have an older home, it’s probably under-insulated. Over time, attic insulation settles, which reduces its insulating barrier and its ability to keep summer’s heat or winter’s chill out of your home.
Insulation keeps your home warm in the winter and cool in the summer. Without proper insulation, the hot or cold air outside can seep into your living space causing your air conditioner or heater to work harder than it should to keep your home comfortable. This can lead to higher-than-expected energy bills.
You may want to consider adding insulation if you meet any of the following:
Insulation is measured in resistance value (R-value). The thicker the insulation, the higher the R-value. Duke Energy recommends that homes have insulation with an R-value of at least 30 to be energy efficient.
R-value is a measure of thermal resistance. It measures the resistance of an insulating or building material to heat flow. A higher R-value means that the insulation has more resistance – which means it will be more effective at blocking heat flow.
The incentive will vary based on your insulation’s current R-value and the square footage of your attic space.
If your insulation is less than R-12:
If your current insulation is between R-12 and R-15:
No. You must use a Duke Energy prequalified contractor to install the insulation. Do-it-yourself installations do not qualify. In addition, you must complete a free Home Energy Check within the 24 months prior to having the insulation installed to qualify for the incentive.
On average, homes can see an annual savings of up to $130 for upgrading their insulation. Estimated yearly savings are based on a single-family 1,800 sq. ft. home with 15,316 annual kWh calculated at $.13/kWh and on engineering approximations from Duke Base Study, DOE and ENERGY STAR®. Actual savings may vary due to weather, energy use habits and home characteristics.
On average, our customers pay around $300 for added insulation. The average insulation cost is based on the actual cost of work completed within Duke Energy’s service territory. Actual insulation costs and rebate amounts will vary based on: the current R-value of your home’s insulation, type of insulation, whether your insulation is upgraded to R-19 or R-30 and the total square footage of installed insulation. Your contractor will be able to provide you with a more exact estimate at the time of your appointment.
To qualify, you must begin with a free Home Energy Check.
