The Luxaire Acclimate furnace line of gas-fired 80 percent AFUE downflow models now incorporate downflow and horizontal configurations. The furnace line includes variable-speed, two-stage and single-stage models. The Acclimate gas-fired 80 percent variable-speed furnaces are equipped with GeoTraK technology, which enables Acclimate installers to customize performance for each home. Unlike standard blower motors, the ECM offers nearly continuous, gradual fan speed operation, resulting in more energy-efficient operation, according to this company.
