Our house is located in southern Oklahoma, summers 110 and winter days as cold as about 25f. Our house is about 2400sq feet, 4 bedrooms, one story brick. It seems to be fairly well insulated, and was built in 1974. Our current ac system is a Dymler Chrysler (no joke) the ac no longer works and the furnace part is too expensive to run.I would say it was installed in 1974. It us ducted in the floor (house on pier and beam). Any suggestions on most efficient and best on the market?? Also I am sure we are going to have to run new ductwork, should we put it in the attic this time??
Please help I have read and read and still not sure what exactly would be the best for us.
p.s. we are total electric
