Pay-As-You-Save for Home Efficiency Upgrades
How It Helps Homeowners
The PAYS® (Pay-As-You-Save) program lets Missouri homeowners enjoy comfort upgrades and energy savings now, with no large upfront costs. Repayments are added to your utility bill and are typically less than the savings from your energy-efficient improvements.
Eligible Upgrades
- High-Efficiency HVAC Systems – heat pumps and central systems
- Smart Thermostats – precise, easy-to-use temperature control
- Attic/Ceiling Insulation – keep heat where it belongs
- Air Sealing & Duct Repairs – stop drafts and leaks for year-round comfort
How It Works
- Schedule a free home energy assessment through Energy Stars Heating & Cooling Co and Ameren.
- Review your personalized energy plan with recommended upgrades.
- Choose the upgrades you want — Ameren covers a portion of the upfront cost.
- Repay over time via your utility bill while enjoying immediate energy savings.
Take the first step toward a more efficient, comfortable home today!
