Calgary Home Winter Preparation: Humidity and Safety

Reviewed October 2026. Winter preparation should address water, heat, ventilation, humidity and safety alarms.

Adjust humidity by observation

Outdoor temperature tables are only starting points. Use a hygrometer and watch for condensation, frost, mould or water on windows and frames. Reduce humidity and improve ventilation when those warning signs appear.

Keep safety systems working

Test smoke and carbon-monoxide alarms and replace them according to the manufacturer's instructions. Keep furnace and water-heater vents clear of snow and ice.
