California Heat Pump Partnership Maps Path to 6 Million Installs by 2030

A 30-year veteran of residential HVAC who's crawled through more attics than he can count.
The California Heat Pump Partnership published its first large-scale adoption blueprint in March 2025 with a blunt message: at the current installation pace, California will reach only about 4 million heat pumps by 2030 — roughly 2 million units short of its 6 million target. Permitting delays, a thin installer workforce, upfront cost, and incentive complexity are the four ceilings.
CAHPP is a public-private coalition. Its Market Advisory Board includes manufacturers representing more than 90% of the U.S. consumer heat pump market — Bosch, Carrier, Daikin, Fujitsu, Lennox, LG, Mitsubishi Electric, Rheem, A.O. Smith, and Trane — plus retailers and distributors (Home Depot, Ferguson) and major utilities including Pacific Gas and Electric, Southern California Edison, SMUD, and San Diego Gas & Electric. This is the first time the group has published a statewide plan with specific gap estimates and a coordinated strategy set.
What Has to Change
The 2 million unit gap isn't subtle. As of the end of 2024, about 1.9 million heat pumps were installed statewide, and the blueprint projects the current trajectory lands near 4 million by 2030 — well below the 6 million target. Closing that gap means roughly doubling the pace of adoption over the rest of the decade.
Permitting is the first bottleneck CAHPP calls out: heat pump installs run through hundreds of separate local jurisdictions, each with its own plan check, fees, and inspection sequence, and the blueprint lists modernizing local permitting among its core strategies. The model it points to is SB 379, the existing solar-permitting law (SolarAPP+), as the template for fast, automated approvals. SB 282, the Heat Pump Access Act (Sen. Wiener), would extend that approach to heat pumps: real-time/expedited permit issuance, a single permit per install, contractor self-certification of code compliance, capped permit fees ($50 for a heat pump water heater, $150 for a heat pump HVAC system), and CEC-issued standardized two-page permitting checklists due by July 1, 2026, with automated online permitting platforms required by July 1, 2027. The bill is moving through the Legislature with CAHPP and Building Decarbonization Coalition backing.
Workforce is the second ceiling. The blueprint flags a shortage of trained installers as a key barrier and calls for expanded training and workforce development, though it does not publish a specific headcount target. Several CAHPP members are funding apprenticeship and training programs directly.
Upfront cost and incentive complexity are tangled. With HEEHRA waitlisted and state rebate programs varying by utility, the installer's incentive pitch has gotten harder, not easier. CAHPP recommends a single unified state portal that calculates stackable rebates for a specific address and income level. The CEC has said it's evaluating the idea.
Manufacturer Positioning
If you sell in California, read the CAHPP blueprint before your next dealer meeting. Manufacturer programs that align with the state's 2030 plan will get preferred training, preferred inventory, and probably preferred co-op dollars. The ones that don't will get squeezed.
That's not a small thing for contractors. When Bosch, Carrier, Daikin, Fujitsu, Lennox, LG, Mitsubishi Electric, Rheem, A.O. Smith, and Trane all sit on the same coalition board, their California dealer programs are likely to converge on similar training requirements and similar rebate structures. Shops that are certified across multiple lines will have more flexibility than single-brand dealers.
One notable absence among the major HVAC names is Johnson Controls, which is not on CAHPP's Market Advisory Board. That doesn't mean the brand is losing California — it means it isn't at the table helping shape the policy that will define the market through 2030.
What happens next: CAHPP and its partners are pressing for SB 282's passage and implementation, and the partnership continues to coordinate on permitting, incentives, and workforce strategy. The blueprint is public at heatpumppartnership.org.
