Is the GC9C96 Right for Your Home?
Two-stage operation means the burner runs on low fire most of the time and only steps up to full output on the coldest days. In the Fraser Valley’s long stretch of mild, damp winter weather that is most of the season, so you get steadier room temperatures, quieter operation and fewer of the temperature swings a single-stage furnace produces. Choose the GC9C96 specifically when your ducting requires a downflow or horizontal furnace — the upflow GM9C96 is the equivalent unit for a standard basement installation.
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 is a downflow furnace?
A downflow furnace pulls return air in at the top and pushes heated air out the bottom. It is used where the furnace sits above the space it heats, such as a main-floor closet or utility room over a crawlspace.
How do I know which orientation I need?
Follow the existing ductwork — the direction of supply and return connections tells you. We confirm it on site before ordering anything.
Does the downflow model give up any efficiency?
No. The GC9C96 carries the same up-to-96% AFUE rating and the same two-stage, multi-speed ECM design as the upflow version.
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.
