I didn't say air handlers are heat pumps, I said the product of the heat pump are passed off to the air handler. But again you seem confused about basic terminology about the subject you are talking about. > An air handler can be put in place of a furnace, but it certainly does not have to. An air handler just moves air around, it doesn't replace a furnace. Its an essential part of a central heating / cooling system regardless of whether its attached to a heat pump, gas furnace or anything else. I'm not sure why you keep doubling down on speaking authoritatively about something you don't understand. Why don't you read a basic intro and then you'll understand?
