    Was there any specifig brand/seer rating restriction with the GHGrant? I just applied and will be going this route, but I don’t want to be paying $15000 for a specific brand or something if I can get similiar equipment that might not be on a list.

      It’s more complicated than that. The major components of the system all have to be qualified for the rebate, down to the component model numbers. There’s a lookup tool to see which model numbers qualify. For a hybrid setup like mine, there are three parts:

      • Outside model number: this is the actual heat pump component that gets installed outside
      • Inside model number: this is the condenser coil that gets installed on top of the furnace
      • Furnace model number: this is the model number of the furnace itself

      A ductless system would only have two part numbers involved, the outside heat pump unit and the inside wall unit. No furnace for a ductless system of course.

      Every HVAC company I talked to was pretty knowledgeable about the GH program, so if you tell them you’re an applicant for the program then they should put together a quote that qualifies. Multiple HVAC reps advised me to make sure that all rebate-covered part numbers were listed clearly on the invoice. Apparently if that info is missing it can derail the rebate until the invoice is updated with full info.
