Goodman GM9S96 Gas Furnace

The Goodman GM9S96 is a single-stage, multi-speed gas furnace rated up to 96% AFUE, built for upflow and horizontal installation. It is a straightforward, well-priced high-efficiency replacement for an older mid-efficiency furnace.

Is the GM9S96 Right for Your Home?

Single-stage operation means the burner runs at one output level. It is the simpler, lower-cost option, and paired with the multi-speed ECM blower it still holds temperature well and runs far more efficiently than the mid-efficiency furnace it usually replaces. It suits homes where the budget matters most and the existing ductwork and layout are already working well.

Getting the Size Right

A furnace that is too large short-cycles, wears itself out and leaves uneven temperatures room to room. We size every replacement from a heat-loss calculation on your actual home — square footage, insulation, window area and orientation — instead of matching whatever was there before. Ask about current BC rebates before you decide; they can change which system makes financial sense.

Frequently Asked Questions

What does 96% AFUE actually mean?

AFUE is the share of fuel energy that becomes usable heat over a full heating season. At 96% AFUE, about 96 cents of every dollar of gas heats your home and roughly four cents goes up the vent. An older mid-efficiency furnace often runs closer to 60–80%.

Can the GM9S96 replace my existing furnace directly?

Often yes, but not always. As a condensing furnace it needs PVC venting and a condensate drain, which an older chimney-vented furnace does not have. We confirm venting and drainage during the estimate.

Single-stage or two-stage — which should I choose?

If you want the lowest installed cost, single-stage is the sensible pick. If even room temperatures and quieter running matter more, look at the two-stage GM9C96.

Big Valley Heating & Sheet Metal installs this furnace across Maple Ridge, Pitt Meadows, Coquitlam, Port Moody, Anmore and the wider Fraser Valley. Because it is a condensing furnace, it vents through PVC rather than a traditional chimney, which affects where it can go in your home — something we confirm during the site visit, not after.
