Matched Indoor System

When properly matched with a variable speed furnace or air handler, your outdoor unit can, in many cases, provide an elevated SEER rating.

True Variable-Capacity Cooling

Rather than running at one or even two speeds, the 20LX Inverter-Driven Scroll Compressor changes its speed in small, precise increments and adjust cooling up and down like a dimmer switch. So temperatures are held exactly where you want them, even in extremely hot weather.

Anti-Microbial Protection

On Matched AirEase Indoor Coil. Drain pans are infused with an antibacterial agent that destabilizes the membrane of microorganism cells, disrupting the cellular function of odor-causing mold and bacteria so that they can no longer grow or reproduce.

Pro Series™ Systems

Pair this model with a Pro Series™ variable speed furnace and a Comfort Sync 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. Explore the AirEase Pro Series™.

Heavy-Duty Compressor Blanket

Greatly reduces operating sound so your outdoor entertaining is not interrupted.

Swept Wing Fan Blades

High-tech design allows for better sound control and is engineered for long-lasting durability. A heavy-duty insulation guard further reduces noise levels.

Integrated Compressor Protection

The combination of both high and low pressure switches protect the compressor, the heart of the system. High and low pressure switches guard against a variety of conditions to help keep your system running for years.

Internal Monitoring

Your AirEase air conditioner's electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention.

MHT™ Technology

AirEase'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.
