High Efficiency Comfort Systems

The A7AC22V variable-capacity air conditioner delivers highly energy efficient cooling with up to 22 SEER2 efficiency. Its inverter-driven compressor changes speed in small' precise increments like a dimmer switch' holding temperatures exactly where you want them while using significantly less energy than a conventional single-stage unit. This model uses next-generation R-454B refrigerant with lower global warming potential.

Pair this model with a Pro Series™ variable speed furnace and a Comfort Sync® A3 thermostat for optimum performance. With the Pro Series' you're in control of every aspect of your home's climate' as well as your energy costs.

• Up to 22 SEER2 Efficiency The highly energy efficient cooling on this air conditioner can deliver more than 39% greater energy efficiency than a conventional 14 SEER single-stage air conditioner unit. ENERGY STAR® Most Efficient certified.
• True Variable-Capacity Cooling The inverter-driven compressor changes its speed in small' precise increments and adjusts cooling up and down like a dimmer switch. Temperatures are held exactly where you want them' even in extremely hot weather.
• Comfort Sync® A3 Thermostat Enabled Unlock total control over your home's ideal environment from anywhere using a smartphone' tablet' or laptop. The Comfort Sync system continuously monitors internal components for optimum performance and alerts you when maintenance is needed.
• Omniguard® Total Corrosion Protection Improved corrosion protection compared to traditional coils extends the life of the unit and maintains peak efficiency.
• 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.
• Quiet Operation Quiet Shift Technology delivers approximately 50% lower noise levels compared to a 10 SEER single-stage unit. Swept-wing fan blades and a heavy-duty compressor blanket further reduce sound levels.
• Integrated Compressor Protection The combination of both high and low pressure switches gives additional reliability to each Armstrong Air cooling unit' protecting the compressor from unsafe refrigerant pressures.
