The City has partnered with Ameren Act On Energy to help make Champaign homes more energy efficient. The program offers FREE home energy audits and will boost Ameren's incentives for insulation and air sealing by an additional 20%. On average these incentives pay for nearly half of the project costs. This is one-time funding and it is given on a first come, first-served basis. If you are a Champaign resident of a single family or duplex property, call Ameren and sign up today!
