A heat pump freezing up in winter can be a common issue, but it often requires prompt attention to prevent further damage or system inefficiency. Here’s what you can do if your heat pump freezes up:
Turn Off the Heat Pump
- Switch off the system to prevent further damage.
- Avoid using emergency heat unless necessary to prevent overworking the system.
Inspect for Ice Buildup
- Check the outdoor unit: Look for visible ice on the coils or the entire unit.
- If the ice is minimal, allow the defrost cycle to take care of it. If there’s heavy ice, proceed cautiously.
- Check for error codes or malfunction signals on the thermostat or system panel.
- If the defrost cycle isn’t activating, contact a professional technician.
Ensure Proper Airflow
- Clear Debris: Remove snow, leaves, or dirt around the unit to allow proper airflow.
- Check Air Filters: Dirty filters can restrict airflow, causing freezing. Replace them if needed.
Examine Refrigerant Levels
- Low refrigerant can lead to freezing issues. A professional HVAC technician should check and recharge the system if needed.
Check for Blockages in the Coils
- Dirty or blocked coils can cause freezing. If you suspect this, please call a professional.
When to Call a Professional Technician
- If you cannot resolve the issue, or the unit continues to freeze, seek help from a licensed HVAC professional. Persistent freezing may indicate a more significant issue, such as:
- A faulty defrost sensor
- Damaged or worn-out components.
