The Goodman GMSS96 is the entry point into Goodman's high-efficiency 96% AFUE lineup. It's a single-stage furnace — meaning it operates at full capacity or off — with a permanent split capacitor (PSC) blower motor rather than the variable-speed ECM motor found in the GMVC96 and GMVC98. For budget-conscious Minnesota homeowners who want high efficiency without the premium price, the GMSS96 deserves a close look.

Who Is the GMSS96 Right For?
Great choice if: budget is the primary concern and you want 96% AFUE without the GMVC96 premium; you're replacing an old 80% furnace and want the biggest efficiency jump at lowest cost; the home is well-insulated and a single thermostat set point works well; or you're installing in a rental property or vacation home where premium comfort features aren't a priority.
Consider upgrading if: you experience temperature swings or hot/cold spots in your home; you're sensitive to furnace noise; or you run your furnace heavily and want the best long-term comfort investment.
96% AFUE Savings vs. 80% Furnace
Upgrading from an 80% AFUE furnace to the GMSS96 at 96% AFUE saves approximately 17% on your gas heating costs. For a Minnesota home spending $1,200/year on heat, that's roughly $200/year in savings — a payback of 3–5 years on the efficiency upgrade alone (compared to a new 80% unit). See our Minnesota furnace installation cost guide.
Warranty Highlights
Like all Goodman furnaces, the GMSS96 carries a lifetime heat exchanger warranty and 10-year parts warranty when registered within 60 days of installation. This warranty protection is exceptional for a budget-tier furnace. See our guide on furnace warranty registration.
