Family hanging out on couch in front of snowy window - How does a heat pump work in cold weather? 

During winter, heat pumps work by reversing the flow of refrigerant to extract thermal energy from the outdoor air. Modern heat pumps use refrigerants with a lower boiling point to continue working in colder temperatures. In extreme cold (below -20°C), a supplemental heating system may be required to warm your home properly.

How to Keep Your Home Warm with a Heat Pump This Winter 

  1. Ensure proper installation: For optimal performance, it’s important to have your heat pump installed by a professional. Proper installation includes correct sizing, appropriate ductwork, and a suitable refrigerant. 
  2. Regular maintenance: Regular maintenance is essential to keep your heat pump running efficiently. This includes cleaning or replacing air filters, checking refrigerant levels, inspecting the outdoor unit, and scheduling annual tune-ups. 
  3. Keep the outdoor unit clear: It’s important to keep the outdoor unit clear of debris and snow during the winter months. This ensures proper airflow and therefore better efficiency.  
  4. Adjust thermostat settings: Set your thermostat to a lower temperature when you’re not home to maximize efficiency and adjust as needed for comfort.
