Two Stage Cooling
Staying Comfortable with Two Stages of Cooling
Mid SEER air conditioners feature an energy efficiency rating of up to 18.0 SEER. Air conditioners with this efficiency rating also feature two stages of cooling much like two-stage furnaces provide two stages of heating. A two-stage air conditioner will cool your home on a low cool stage most of the time. When weather conditions change rapidly and hot days roll in, the second stage of cooling kicks in to provide additional comfort and increased cooling capacity with less energy. A mid SEER air conditioner is an energy efficient choice that will save you energy dollars with a high level of comfort.
