Replacing 3 ton air handlers with 2-5 tons
Just bought a large 12,000 sq ft home that has 2-3 ton AC units servicing first floor. Units are relatively new but are grossly undersized based on my manual j heat loss calculations. I am replacing them with 2- 5 ton units with hydronic heat coils. I was wondering if there is anyway I can just get rid of the 3 ton air handlers and keep the 3 ton condensing unit a, line set and ac coil. I know this is unorthodox and not effecient but the current 3 ton condensers are relatively new and it kills me to throw them out. We rarely will use AC and use the units primarily for heating. I don't want to add extra units so they run in tandem as there is no room. Both existing units are on opposite ends of house.
