Why would some recommend a higher SEER rating? I live in NE Ohio and we are looking at putting in a Goodman electric furnace with an add on heat pump at 13 SEER. (3.5) ton.
A number of people have suggested that we should go with the 16 or 18 SEER. I understand that the SEER deals with the cooling side. Is it worth the extra cost from 13-16 or 18 when we only have 2.5 months of time when we would really use AC?
