Heat Pump

Standard-Efficiency Heat Pump

13 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.
7.7 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.
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.

All-in-One Design

Our single unit design was developed to keep all heating and cooling operation outside of the home, keeping sound inside your home to a minimum.
Vibration Reduction

Each compressor was constructed with rubber pads to reduce vibration during operation. Less vibration lowers sound, so your outdoor entertaining is not interrupted.

Internal Monitoring

Your Armstrong Air packaged unit's electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention.
Integrated Compressor Protection

Integrated Compressor Protection: The combination of both high and low pressure switches give additional reliability to each Armstrong Air cooling unit. The high pressure switch prevents operation in the event that refrigerant pressures exceed safe levels, protecting the compressor. In the event that your unit does not have enough refrigerant, the low pressure switch prevents the unit from drawing in moisture and other contaminants while operating.
Warranty

Armstrong Air’s commitment to a better product is backed by a 10-Year Limited Warranty on parts.
