Q: If a homeowner claims a $1,500 credit for installing a qualified appliance, are they still eligible for the solar or geothermal credit?

A: Yes. The capped $1,500 tax credit for most HVAC equipment is separate from the uncapped geothermal, solar, and wind tax credit. For example, a homeowner could install a qualifying water heater and claim 30% of the installation costs up to $1,500 then install a geothermal heat pump and claim up to 30% of that total installation cost as well.
