Gas furnace efficiency is measured based on the Annual Fuel Utilization Efficiency ratings, (AFUE). The higher the percentage the more efficient the unit. This furnace delivers up to 92.1 AFUE (Annual Fuel Usage Efficiency). Older furnaces may deliver as low as 50-60% efficiency. Properly sized and installed, this furnace is 25-40% more efficient than older models. In fact, the Westinghouse Two-Stage Variable Speed Furnace is so efficient it qualifies for the EPA's Energy Star® rating for reducing energy consumption.

Features and Benefits:

• Westinghouse furnaces feature a SmartLite® Control Board to increase the life of the igniter beyond the standard 20-year life expectancy. SmartLite® learns and adapts its ignition process to the furnace.

• Westinghouse Two-Stage Furnaces operate at lower capacity during mild winter days and at full capacity during colder days. Because this furnace idles down to a reduced capacity, it provides better comfort and performs quieter then a single-stage furnace. Longer cycles improve air circulation, minimizing temperature swings, while reducing hot and cold spots.

• The cabinet is fully insulated to shield operation sound, making this furnace one of the quietest available today. Its Silicone-protective polyurethane coating resists scratching, and prevents rusting, keeping your furnace looking new for years to come.

• Westinghouse furnaces are service-friendly and accept add-on components with ease, and can reduce common allergens and irritants, such as, dust, mold, pet odor, and dry air. Contact your Westinghouse dealer for more details.

• The GE ECM™ Variable-Speed Blower technology automatically compensates for reduced duct volume, dirty air filters, zoning changes, obstructed registers, etc. and reduces electrical consumption close to 80% over conventional indoor furnaces, thereby reducing utility costs.

• Longer cycles and gradual increases in air circulation, virtually eliminate temperature swings, as well as, hot and cold spots providing balanced comfort in your home.

• The 92.1%* AFUE Two-Stage Variable Speed Gas Furnace meets the Energy Star® guidelines for efficiency and performance.
