Surge protection should installed on the incoming power supply of all new inverter HVAC equipment. For some reason, manufacturers don’t want to spend the money to protect sensitive electronics.
I installed a whole house surge protector in my main breaker panel after losing my furnace blower motor to a huge power surge.
