Lennox G50 Furnace
Overview of G50
The Lennox G50 is a gas furnace that is part of the Lennox Elite Series. The G50 has an efficiency rating of 80% AFUE, which is a low efficiency when compared to other furnaces manufactured today. Lennox claims it can save between $1115 and $2197 for 3 years of use when compared to older furnaces with 55% to 65% AFUE rating.
The furnace has a low-speed blower fan that the company says provides slower air circulation and an insulated blower compartment which the company claims reduces sound. It can also be used with an electric heat pump. When used with the heat pump, it will alternate between electric and gas heat, reducing fuel usage.
