Reliability

Quality components provide worry-free reliability. You can count on Armstrong Air 418LT air conditioners and heat pumps for years of dependable comfort. The two-stage compressor raises the level of comfort, and lowers utility bills. Its revolutionary two-step design allows the compressor to operate at low speed most of the time for quieter, more consistent comfort and better humidity control.

Quiet Operation

A blanket of insulation lets you relax in quiet comfort. Units are designed to provide maximum comfort while keeping sound at a minimum. A heavy-duty insulation blanket surrounding the compressor and a wire fan guard significantly reduce operating sound. Heat pumps use a discharge muffler, along with QuietShift™ technology during the defrost cycle, to control sound.

Energy Efficiency

Conserves energy and protects the environment. Armstrong Air 418LT air conditioners and heat pumps exceed Energy Star® guidelines for energy efficiency and savings. With an efficiency rating of up to 18 SEER, these units can reduce your energy costs, compared to older, less efficient equipment. UltraTech™ Scroll compressor uses R410a refrigerant, which meets government standards for non-ozone-depleting appliances.

The 18 SEER unit features the high-tech swept-wing fan blade, which provides superior sound control through new aerodynamic design.
