The rebates are intended to encourage customers to purchase high-efficiency equipment and offset the additional cost of doing so. The amount is based on an average of the higher cost of the different high-efficiency models.

In addition to the incentive amounts listed on the rebate charts, Ameren Missouri works with HVAC distributors to promote the installation of higher efficiency equipment. For select equipment, such as 18+ SEER CAC and ASHP, and ductless systems, incentives may vary by program and measure type.

For the continued success of the program, it is important for customers to be aware that Ameren Missouri provides the rebates. If the program rebate helped customers decide to upgrade or service their system, it is important they state that if receiving a follow-up survey or call.
