Customer Surveys
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. Results are summarized in the report below.
