Found multiple pull air leaks on both systems and attic, the 3 ton is getting a 10 degree split temp (20 is what I'm looking for). Refrigerant pressures were indicating a restricted evaporator coil, high superheated and low subcool telling me not enough freon is making it back to the compressor from the evaporator coil. I also noticed the gas line does not have a sediment trap and there is no flat switch for the condensation.
