What Factors Would Lead To a Frozen Heat Pump?
As we have mentioned above, a frozen heat pump could be the result of many factors. Before you embark on dealing with your frozen heat pump, it is best to get to the underlying cause so as to prevent future occurrences. If you are experiencing a frozen heat pump, then you should check whether any of these factors is the reason for it.
- Low refrigerant levels: If the refrigerant levels of your HVAC system are low, then it means that the system will not be able to defrost normally, which will lead to a build-up of ice and could eventually lead to the system breaking down. A frozen heat pump as a result of low refrigerant levels is best handled by a professional. The technician will restore the levels back to normal and check for leaks so that you do not continue to experience the same.
- Bad defrost thermostat: If the defrost thermostat or sensor has malfunctioned, then you are likely to end up with a frozen heat pump. This is because the sensor must detect that frost is building up on the heat pump so that the defrost cycle kicks in.
- Lack of air flow: A clogged or damaged air filter will limit the air flow, and this may lead to a frozen heat pump. If you suspect that a lack of airflow is the reason for your heat pump, then you should check the unit to ensure it is clean and in great working condition. Regular HVAC maintenance should prevent any dirty and damaged air filters.
- Malfunctioning outdoor fan motors: The defrost cycle relies on the outdoor fans. Because of this, should the outdoor fan motors stop working, the defrost system will not work as well leading to a frozen heat pump. In this case, you will need a professional to look at the fans and ensure that they are working just fine.
