St. Louis HVAC Rebates

Rebates & Tax Credits for HVAC Upgrades in 2025 (St. Louis / Metro Area)

Upgrading your HVAC system is one of the best ways to save energy and cut your utility bills — and in 2025 there are several powerful incentives you should know about. At Thomas Hoffmann Air Conditioning & Heating, we help you navigate them so you get the most savings.

Spire Energy – High-Efficiency Heating Rebates
If your home is served by Spire in Missouri, you can qualify for rebates when you install equipment such as a high-efficiency natural-gas furnace, water heater, or thermostat. Examples: up to $300 for a qualified 96 %+ AFUE furnace. Contact us to check eligibility and claim the rebate application.

Ameren Missouri – FastTrack / PAYS® HVAC Program
For homes in Ameren’s service area, the traditional HVAC rebates have been replaced by the FastTrack HVAC / PAYS framework. You may still be eligible for upfront rebates on high-efficiency central air conditioners, heat pumps, geothermal systems, and smart thermostats — along with simplified financing via your utility bill. Reach out and we’ll review your home, system, and potential savings.

Federal Tax Credits
On top of utility rebates, federal tax incentives may apply to your system upgrade. For example, certain air-source heat pumps and ground-source (geothermal) systems qualify for credits up to 30% of the cost (or up to $2,000+). We handle the paperwork and ensure your equipment meets the specs.

Why work with us?
Unlike big national contractors, we’re locally owned, licensed, and based right here in the St. Louis area. We know these programs, we ensure your system qualifies, and we walk you through the paperwork — making the process easy and stress-free.
