High Efficiency Ratings*

PRPHP16 units offer efficiency ratings of up to 16.00 SEER and 8.2 HSPF, so you can enjoy consistent savings through every season. You may even be eligible for local utility rebates and other energy incentives.*

Variable-Speed Operation

By changing the speed of its airflow during start-up, your package unit can create more even temperatures throughout your home, while enhancing efficiency and reducing operating noise.

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.
