Complete winter care guide for heat pumps in Metro Vancouver.
Call 778-909-5731Modern cold-climate heat pumps are designed to provide efficient heating at temperatures well below freezing, with some models operating effectively down to -25 degrees Celsius. In Vancouver, where winter temperatures typically range from 1 to 8 degrees Celsius, even standard heat pumps should perform well. However, proper winter maintenance is essential for reliable operation.
During cold snaps, your heat pump works harder to extract heat from the colder outdoor air. The system may run longer cycles and enter defrost mode more frequently. This is normal and expected behavior.
Keep the area around your outdoor unit clear of snow, ice, and debris. Maintain at least 24 inches of clearance on all sides for proper airflow.
Check that the defrost cycle operates properly. Normal defrost cycles last 5-15 minutes and occur every 30-90 minutes depending on conditions.
Replace air filters monthly during winter. Clean filters are critical for efficient heat pump operation.
Ensure your backup electric heat strips are functioning properly. Test by raising the thermostat 5 degrees above room temperature.
If ice doesn't clear after defrost cycle, check for refrigerant leaks, faulty defrost control board, or blocked airflow around the unit.
More frequent defrosting in cold damp weather is normal. If cycles exceed 15 minutes, the system may need service.
If backup heat runs more than the heat pump, outdoor temperatures may be too low or refrigerant charge may be low.
Safety shutdowns during cold weather indicate overheating, high pressure, or electrical issues requiring professional diagnosis.
