Get Comfortable Saving Energy

Home Efficiency Program

If you are looking to make a smart investment in a more energy-efficient home, the Home Efficiency program can provide an easy and affordable way to do just that! Thousands of homeowners across the Ameren Illinois territory have enjoyed the benefits of participating, including:

  • Typical savings of 20% or more on energy bills
  • Fewer drafts and more comfortable rooms
  • Work performed by specially trained contractors (Program Allies)
  • Increased long-term value of your home
  • Potential to earn an Illinois Home Performance with ENERGY STAR® Gold or Silver Certificate

It all starts with a home energy audit, which helps identify where your home is wasting energy so you can get to the root of common household problems – such as drafts, inconsistent temperatures and heating and cooling issues. Incentives are available through Program Allies to help reduce the cost of energy efficiency improvements.

The ENERGY STAR certificate proves that you worked with an approved contractor to make extensive, energy efficiency improvements to your home. After completing the work, our Program Allies submit the paperwork for you to get the certification – so you can just sit back and start saving!
