What unit would be best for San Diego County where no heat is needed at night and only needed from about 5:45 a.m. to 9 a.m.? Average temperatures are 69/45 in winter rarely freezing. We have had solar for 20 years and make 1300 KW extra a year. Would like it to be energy efficient, though. How big are the units? We have a gas heater in a "closet type area" now. Cement slab. One story. 1,600 sq. ft. We have some backup batteries but they don't do heater and A/C. Is the heat pump also A/C? Just starting to look to switch to electric as gas rates doubled last year. Thanks.
For your application a heat pump and air handler would probably be best. An electric furnace would be cheaper to buy, but more expensive to run. You would need to call a local contractor to do’s load calculation on your house to determine sizing and price.
