What type of furnace is best for Ottawa winters?

For Ottawa's harsh winters, a high-efficiency gas furnace with 90%+ AFUE rating is your best choice. These furnaces are specifically designed to handle our extreme cold while keeping heating costs manageable during our long heating season.

High-efficiency condensing furnaces (96-98% AFUE) are ideal for Ottawa because they extract maximum heat from every dollar of natural gas. With our heating season running from October through April, and temperatures regularly dropping below -20°C, the extra efficiency pays for itself through lower monthly bills. These units also include two-stage or modulating burners that adjust heat output based on demand, providing more consistent temperatures and better comfort during milder winter days.

Cold climate considerations are crucial in Ottawa. Look for furnaces with robust heat exchangers and components rated for extreme temperatures. Variable-speed blower motors are particularly beneficial here - they circulate air more effectively during long heating cycles and reduce those uncomfortable hot/cold swings common in older single-stage systems. Many homeowners also pair their furnace with a whole-home humidifier, which is almost essential given how dry our winter air becomes.

TSSA requirements mandate that furnace installation must be performed by licensed G2 technicians, and a permit is required for any new installation or replacement. In Ottawa's market, expect to invest $4,500-$6,500 for a quality high-efficiency furnace installation, including proper venting and TSSA inspection.

Safety is paramount with any gas furnace - ensure your carbon monoxide detectors are working and schedule annual maintenance to keep your system running safely through our demanding winters. A well-maintained high-efficiency furnace should reliably heat your home even during those -30°C cold snaps we experience several times each winter.
