Rebates & incentives in Pennsylvania
HEAR pendingAC-only installs see limited rebates in 2026; the big incentives go to heat pumps, which cool and heat. It's worth pricing a heat pump alongside your AC quote.
Not yet live; check your utility's efficiency rebates.
Status: Pennsylvania has approved IRA funding but had not launched HEAR as of mid-2026 — utility rebates apply now.
The federal 25C tax credit (up to $2,000 for heat pumps; $600 for high-efficiency AC or furnaces) and the 25D credit ended December 31, 2025 under the One Big Beautiful Bill Act — neither is available for 2026 installs. The remaining federal help is the IRA Home Electrification & Appliance Rebates (HEAR): up to $8,000 toward a heat pump for households under 150% of area median income, paid at point of sale where a state has launched its program.
