What heats the home now?

We do not turn this into a system size. An installer measures your rooms to do that. We pass the number along with your request.

What will the heat pump do?
3 tons

Heat pumps are sized in tons. A ton is how much heating and cooling the system puts out, not what it weighs. Not sure of yours? Leave it at 3. The installer works out the real size for your home.
