Rebates & incentives in California
WaitlistedMost 2026 rebates reward switching to a heat pump, not a like-for-like gas furnace. Replacing a gas furnace, your savings are mainly utility efficiency rebates (high-AFUE models) — but pricing out a heat pump often qualifies you for far larger rebates.

Historically $3,000–$5,000+ for gas-to-heat-pump conversions; currently waitlisted.
Status: TECH Clean California was fully reserved statewide on February 24, 2026 — new applicants join a waitlist. Check your local utility (PG&E, SCE, SoCalGas) for open rebates.
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.
