AI summary Contractors frequently mention the CGH Grant more often than Green Heat when discussing incentives for MSHPs. They ask customers about rebate awareness, goals, and income to determine eligibility. Contractors recommend Green Heat only when customers don't qualify for CGH Grant or face time constraints. Promotion methods vary, with some using marketing materials and others relying on direct communication.
MSHP contractor quotes: "Historically, it provided an opportunity for people to get a rebate for a single type of measure who didn't want a home energy assessment, and that made sense. Now that's not the same thing with other programs in t...
AI summary Contractors face challenges with rebate programs, including outdated incentives compared to federal and other provincial programs, difficulties in supporting participants with limited knowledge, communication issues with EOne, and eligibility restrictions for switching from oil heat to ETS. Contractors argue that eligibility criteria should be expanded to encourage switching from oil to ETS.
