4 Reasons Heat Pumps Freeze Up in St. Cloud, FL

St. Cloud, FL residents depend on heat pumps throughout the scorching summers. However, thses systems occasionally malfunction and freeze, leaving you without cool air during the most inconvenient moments. We’ll explain four underlying causes of heat pumps that freeze-up.

1. Insufficient Airflow

Restricted air filters, closed vents or blocked exterior units can limit the airflow of the heat pump, resulting in a constant reduction in heat transfer. As a result, water freezes at the evaporator coils, causing the system to freeze.

2. Refrigerant Issues

A low refrigerant level or the presence of cracks in the refrigerant lines of your heat pump decreases heat transfer. Where there is a low refrigerant charge, the evaporator coil gets extremely cold, and any moisture that develops on it freezes, often resulting in a system freeze-up.

3. Thermostat Problems

Sometimes, people incorrectly set a thermostat, or it becomes faulty for another reason, causing the heat pump to work longer than necessary and potentially making the room colder. This is due to its extended operation time, which can contribute to freezing issues if the system is below the optimal temperature.

4. Outdoor Temperature Extremes

Areas like St. Cloud, FL experience hot summers, but the hot days are also common during the spring and early to mid-fall. During high temperatures, heat pumps can struggle to adapt, potentially leading to freezing up.

Understanding these possible causes of heat pump freeze-ups can help you prevent them and have an optimally functioning cooling system throughout the summer.
