Efficient Package Unit

Up to 14 SEER Efficiency Rating*

SEER (Seasonal Energy Efficiency Ratio) rates the energy efficiency of your cooling equipment. The higher the SEER rating, the more efficiently your unit operates, saving you money on utility bills.

Up to 8.0 HSPF Efficiency Rating*

HSPF (Heating Seasonal Performance Factor) rates the energy efficiency of your heat pump. The higher the HSPF rating, the more efficiently your unit operates, saving you money on utility bills.

Up to 6.7 HSPF2 Efficiency

HSPF2 stands for Heating Seasonal Performance Factor and is a measurement of a heat pump’s heating efficiency. As with SEER2, HSPF was updated to HSPF2 to help reflect your system’s performance after installation.

Quiet Shift™ Technology

Allows heat pumps to enter defrost mode without excessive noise. Since refrigerant pressure is allowed to equalize before the switch, the heat pump can dissipate performance-robbing frost and ice quietly.

MHT™ Technology

Armstrong Air’s proprietary heat transfer system. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. They combine for maximum heat transfer and efficiency.
