Toronto winters can be unpredictable. One week may bring mild temperatures, and the next may hit with freezing winds, snowstorms, or sudden drops well below zero. These weather swings can put real stress on your home’s HVAC system. Even with proper maintenance, your furnace or heat pump can experience freeze-related damage that affects comfort, efficiency, and reliability.
Understanding how snow, ice, and freezing conditions impact your heating system can help you spot problems early and take action before a minor issue becomes a major repair.
