SEER2 and Duct Integrity in El Dorado Hills
SEER2 is the current federal efficiency rating for AC units. A 17 SEER2 unit uses roughly 15 to 20 percent less energy than a 14.3 SEER2 unit. In El Dorado Hills, where an AC runs several months per year at high load, that gap adds up to real savings on your PG and E bill.
Duct leakage undercuts SEER2 gains. If 20 percent of your cool air leaks into the attic before it reaches a room, the unit has to run 20 percent longer to hit the set point. Fresh Air measures duct leakage at the estimate and quotes repairs separately. You choose whether to do them now or later.
