California energy rebate landscape
California is a Tier A state — robust state-level energy programs layered on top of federal IRA rebates. Homeowners here can typically access the deepest rebate stack in the country.
Federal foundation (available in California like every state)
- IRA 25C tax credit — up to $3,200/year on heat pumps, HVAC, envelope, audit
- IRA 25D tax credit — 30% uncapped on solar, geothermal, batteries through 2032
- DOE HOMES rebate — performance-based, up to $8,000/home, administered by California Energy Commission / CPUC
- DOE HEAR rebate — income-capped (≤150% AMI), up to $14,000/home, administered by California Energy Commission / CPUC
California state energy office / lead administrator
California Energy Commission / CPUC is the entity administering the federal HOMES and HEAR programs in California. Visit their website for current program rollout status, contractor lists, and application portals.
State program highlights
California's CPUC-mandated efficiency programs are the deepest in the country. TECH Clean California subsidizes heat pump installs through participating contractors. SOMAH covers low-income solar. The CSI-Thermal program (now winding down) covered solar water heating. Net Energy Metering (NEM 3.0) sets the rules for solar export compensation.

Each utility runs its own efficiency rebate programs. Common rebates: smart thermostat ($25-$100), heat pump ($300-$3,000), insulation ($0.10-$0.50/sqft), HPWH ($300-$700). Rebate amounts vary by utility and current funding levels — always confirm before installing.
Climate-specific upgrade priorities for California
Federal stack (25C, 25D, HOMES, HEAR) plus utility rebates form the rebate foundation. Climate-specific priorities depend on whether your home's primary load is heating, cooling, or balanced.
How to put together your California rebate stack
- Identify your utility from the list above and visit their efficiency-program page for current rebate offerings.
- Check California Energy Commission / CPUC's site for HOMES and HEAR rollout status (whether the program is live in your county and what contractors are approved).
- Confirm equipment eligibility — federal 25C requires CEE Tier 2 or ENERGY STAR Most Efficient depending on category; utility programs often require ENERGY STAR.
- Get pre-approval if your utility or HOMES requires it (many do — skipping pre-approval voids the rebate).
- Install via a licensed contractor; collect AHRI certificate, manufacturer's certification statement, and itemized invoice.
- Submit utility rebate within the post-install window (typically 30-90 days). File federal credits via IRS Form 5695 with your tax return for the year equipment was placed in service.
