What is the understanding within this Forum regarding the transition from 10 SEER to 13 SEER? Can a homeowner replace the condenser with a 13 SEER and leave the 10 SEER evaporator in place?
I totally understand that the 13 SEER efficiency is lost if the indoor/outdoor SEER ratings are mis-matched. That is not my question. I am asking if the DOE has mandated that the indoor/outdoor components have the same SEER?
