Overview
Punch winter chill right in the face with a Goodman GDS8 Series Energy-Efficient Multi-Speed Gas Furnace. Built around a heavy-duty aluminized-steel, dual-diameter tubular heat exchanger that is backed by a Lifetime Heat Exchanger Limited Warranty, the GDS8 Series delivers the power and control you need to combat the fiercest cold. For a dedicated downflow installation, this unit with its legendary Goodman craftsmanship is the only gas furnace you will ever need.
Time to replace your outdated furnace? The first step is deciding the best model for your home. The GDS80 gas furnace operates in downflow, so it can be installed in your attic and out of your way. It is 17.5” making it one of the smaller cabinet sizes from Goodman. It is powered with 80% AFUE, or annual fuel utilization efficiency. Keep in mind that the higher this number, the lower your monthly heating costs will be. This unit runs at 80% AFUE meaning it is mid-efficient and 80 cents out of every $1 you spend will go directly to heating your home with loss of about 20%. Because this furnace is mid-efficient, it costs less on the frontend and will keep your heating costs to a reasonable rate.
The 80k BTU 80% AFUE Multi Speed Goodman Gas Furnace - Downflow - 17.5" Cabinet is a great choice if you are looking for a reasonably priced unit that will function properly for years to come.
