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.
Your facility probably uses rooftop units as an important part of its cooling and heating around the year. These packaged heat pumps operate through the circulation of refrigerant, which is necessary in both heating and cooling mode. 
You took time during the fall to have new heaters installed for your commercial building or industrial facility. It could be new rooftop units, boilers, radiant heaters, or unit heaters. Whatever it was, you depended on the equipment working correctly during another rough Toronto Winter.
Boilers and cooling towers are expected for many commercial and industrial buildings. But they aren’t the only ways to provide proper environmental controls throughout the year. Commercial geothermal systems are types of powerful heat pumps that rely on the thermal energy drawn from the ground to deliver comfort to a facility or business. The heat pump either draws thermal energy from the ground to provide heat, or it changes direction to use the ground as a heat sink where it can deposit thermal energy removed from the building.
