How to heat new addition
Converting a Garage into living space. House will grow from 2000 to 3000 square feet. Already built a new garage so this space will never be converted back. Currently have forced air. Instead of replacing the furnace was told to put a second furnace to handle the new rooms. Current furnace is not in the center of the house so one side of the house is warmer then the other. If I go with another furnace, could I heat a few of the current rooms along with the new addition so each furnace would then heat about 1500 sq feet each? What would be the advantage and disadvantage of this approach?
