Trane introduces its new S-Series family of high efficiency gas furnaces.
The seven models of the S9V2-VS furnace include features to help homeowners save money in both heating and cooling seasons. During the winter, this ENERGY STAR certified furnace is rated at 97% AFUE, meaning it uses less gas to heat your home when compared with less efficient models.
The Annual Fuel Utilization Efficiency (AFUE) is a measure of a gas furnace's efficiency in converting fuel to energy, by projecting the average thermal efficiency for a complete heating season. A higher AFUE rating means greater energy efficiency.
