Energy efficiency equates to cost savings. An Amana® Brand APCH3 R-32 Packaged Air Conditioners offer 13.4 SEER2 performance. “SEER2” stands for Seasonal Energy Efficiency Ratio, a measure used by the U.S. Department of Energy to rate the cooling efficiency of air conditioners and heat pumps. The higher the SEER, the greater the efficiency—and the lower the operating cost. Compared to lower SEER units, an Amana Brand packaged air conditioner can provide significant savings on your electric bill.
