Armstrong Air

DALLAS, TX (December 17, 2007) – Reducing a home’s impact on the environment is as simple as installing high-efficiency Armstrong Air air conditioners and heat pumps, which feature energy-efficiency ratings up to 18 SEER as well as the non-ozone-depleting R410A refrigerant.

Advanced engineering and high-quality components allow Armstrong Air 418LT air conditioners and heat pumps to exceed ENERGY STAR® guidelines for energy savings.

The two-stage compressor design provides just the right level of heating or cooling to keep homes comfortable while helping lower utility bills. In addition to the energy-saving benefits, the UltraTech™ Scroll compressor’s refrigerant doesn’t contain chlorine that can deplete the earth’s protective ozone layer.

Lower energy bills, quiet comfort, worry-free reliability

In addition to helping customers reduce their energy bills, the 418LT systems’ revolutionary two-step design helps create a quieter, more comfortable environment by allowing the compressor to operate at low speed most of the time. The result is more consistent comfort, reduced operating sound and better humidity control.

Advanced system diagnostics continually monitor the units’ operation, which makes servicing the units quicker and more accurate. Pairing the units with select thermostats allows the diagnostics to protect the entire system, detecting certain error codes and even shutting down the unit if necessary to prevent compressor damage.

With their innovative design, improved maintenance access and clean, contemporary appearance, Armstrong Air 418LT systems from Allied Air Enterprises Inc. are an excellent choice for energy efficiency, indoor comfort and overall customer satisfaction.
