Frequently asked questions

How do I know if I'm eligible?

All rebated window air conditioners must be listed by the EPA as ENERGY STAR qualified on energystar.gov. To receive a rebate, you must fill out your rebate application completely, including your Duke Energy Progress account number, and mail it in with the original sales receipt. We must receive your rebate application within 90 days of purchase. Installed units are subject to quality assurance inspections for rebate eligibility.

You must be a Duke Energy Progress customer to qualify. The program is open to residential customers in single-family and manufactured homes that are at least 1 year old. In addition, the program is also available for residential multifamily developments interested in making energy-efficient improvements to their existing residential buildings.

What size room air conditioner should I buy?

Many people buy an air conditioner that is too large, thinking it will provide better cooling. However, an oversized air conditioner is actually less effective – and wastes energy. Air conditioners remove both heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

Why does Duke Energy want to help me use less energy?

By 2030, demand for electricity in the United States is expected to grow by approximately 25 percent. In the past, utilities like Duke Energy would build new power plants to keep up with the rising demand for power.

But building new power plants is expensive, and each takes years to complete. Plus, new power plants can have a negative impact on our environment.

The cleanest, most efficient power plant is the one we never have to build. If we can help our customers save energy – and save money in the process – it can reduce the demand for new power plants.
