Recommendation - Heat Pump or AC?
I live in a 1920 built house in New Jersey which has a gas furnace single pipe steam heating system. For AC in summers we have been using window units.
We are going to have a underhead central air system for our first floor and a ductless system for three bedrooms on the second floor and ductless in a finished attic.
My question is for the first floor should we install a heat pump or ac? We were thinking heat pump as it can act as a backup to our steam heating system. From what I read a heat pump may not work when the outdoor temperate is 40 degrees or below.
Any suggestions or recommendations?
