High-Efficiency Package Unit

High Efficiency Ratings*

PRPDF16 units offer efficiency ratings of up to 16.00 SEER, 8.2 HSPF and 81% AFUE, so you can enjoy consistent savings through every season.

You may even be eligible for local utility rebates and other energy incentives.*

Dedicated Dual-Fuel System

The combination of a gas furnace and an electric heat pump helps control heating costs by seamlessly alternating between the two energy sources, depending outdoor conditions. On mild days, the heat pump cost-effectively keeps you warm. When the temperature becomes cold, the system will automatically switch to gas heating and alternate back to electric heat pump operation to maintain your set temperature. Energy-saving performance is maintained through all transitions, and no heat strips are needed.

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.

Tri-Diamond™ Technology

Our unique Tri-Diamond design increases the heat exchanger’s surface area, making heat transfer more efficient. This allows for a smaller heat exchanger that requires less energy to operate.

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.
