Armstrong Air A7CP21V Heat Pump

Up to 21 SEER2 Efficiency Rating*
The higher the SEER2 (Seasonal Energy Efficiency Ratio) and HSPF2 (Heating Seasonal Performance Factor) ratings, the more efficiently your unit operates, and this high-performing Pro Series™ model with variable-capacity operation can deliver up to 21 SEER2 and up to 10 HSPF2. That equates to more than 36% greater energy efficiency when compared to a traditional single-stage heat pump unit, which saves you money on utility bills month after month.
Up to 10 HSPF2 Efficiency Rating*
The highly energy-efficient heating mode of this all-climate heat pump delivers more than 36% greater energy efficiency than a conventional single-stage heat pump unit. The higher the HSPF rating, the more efficiently your unit operates, resulting in lower utility bills.

Omniguard® Total Corrosion Protection Technology
Our outdoor units feature Omniguard Total Corrosion Protection Technology, offering improved corrosion protection compared to traditional coils and preserving the life of your system for years to come.
True Variable-Capacity Cooling
Eliminate hot and cold swings while conserving energy with variable-capacity technology. Rather than running at only one or two fixed speeds, the inverter-driven compressor adjusts its output continuously in small, precise increments to match the needs of the space. That means temperatures are held exactly where you want them, and air consistently moves through the system to provide natural dehumidification and a more comfortable home environment.
Enhanced Dehumidification
Rather than running at just one speed, the inverter-driven scroll compressor is able to run at lower speeds and longer cycles, removing more humidity from the air for a more dry, consistently comfortable home environment.
Quiet Shift Technology
Rather than running at just one speed, the inverter-driven scroll compressor is able to run at lower speeds and longer cycles. That means approximately 50% lower noise levels compared to a 10 SEER single-stage unit for comfort you’ll never have to think about.
Integrated Compressor Protection
The combination of both high- and low-pressure switches give additional reliability to each of our cooling units. The high-pressure switch prevents operation if refrigerant pressures exceed safe levels, protecting the compressor. If your unit does not have enough refrigerant, the low-pressure switch prevents the unit from drawing in moisture and other contaminants while operating.
