California Heat Pump Market Characterization and Baseline Study
This study is intended to develop a market baseline of heat pump costs and a characterization of the California heat pump market, including air source heating and cooling heat pumps, heat pump water heaters, ground source heating and cooling heat pumps, heat pump clothes dryers, and heat pump pool heaters. The study also explored the opportunities and barriers of integrating heat pumps into affordable and market-rate new construction as well as gathered best practices for program design and implementation from other jurisdictions with mature heat pump programs.

TECH Baseline Market Assessment
In this report, Opinion Dynamics characterizes the residential retrofit, space- and water-heating market in California in 2021. They examine homeowner preferences and decision-making around equipment replacement, as well as their awareness of home upgrade financing and heat pump rebates. They also investigate the availability of a qualified workforce to sell and install heat pumps, including their experience and confidence with heat pumps, and their promotion of heat pump rebates and financing. Finally, they assess the size of the heat pump market in California, looking into shipments and sales.

Opinion Dynamics has distributed surveys to single-family homeowners in two groups: one group representing a sample of the general public, and one group who received a TECH-incented heat pump on a biweekly basis. The purpose of these surveys is to understand decision-making and gauge satisfaction among TECH customers with contractor and installation.

Interim Process Evaluation - Coming Soon
This report is an interim process evaluation of TECH Clean California, conducted approximately eight months after TECH officially launched its incentives on December 7, 2021. This interim process evaluation assesses program design and implementation with a focus on the contractor experience, the customer experience, program operations, and whether program activities have been implemented as intended. The objective of this interim process evaluation is to illuminate opportunities for program optimization and identify lessons learned to inform program scalability.
