Carrier 59SC6A100M21-20 96% AFUE Gas Furnace, 100,000 BTU Single Stage | High-Efficiency Home Heating | Calgary Installation

The Carrier 59SC6A100M21-20 is a 100,000 BTU, 96% AFUE high-efficiency gas furnace designed for reliable home heating in Calgary’s cold winters. Its single-stage gas valve and multi-speed ECM blower deliver consistent warmth, quieter operation, and better airflow than older standard-motor furnaces, helping reduce gas bills while keeping your home comfortable.

This furnace supports upflow, downflow, and horizontal installations and can be vented with either single-pipe or two-pipe systems, making it a flexible choice for most Calgary homes. When paired with a compatible heat pump, it can be used in a HybridHeat setup for even greater energy savings. Durable aluminized and stainless-steel heat exchangers provide long-term reliability, and it is fully certified for installation in Canada. Professional furnace installation is available throughout Calgary and surrounding areas.
