A frozen heat pump leads to excessive strain and other potential problems. Modern heat pumps have defrost settings that can help make it easier and faster to restart after a freeze. Consider these five reasons a heat pump might freeze during any season in Venus, FL:
Improper Installation
Improper installation can significantly impact the airflow around the heat pump, leading to ice forming on the coils. The heat pump needs the correct amount of air to keep the coils at the right temperature.
Similar problems due to maintenance issues may leave homeowners with a heat pump sinking into the ground. This impacts airflow and introduces extra dirt and moisture that can freeze a heat pump.
Dripping Water
Your heat pump may develop ice if water from an outside source drips onto it. Homeowners sometimes find that a nearby gutter has leaked enough water onto their heat pump to freeze it.
Low Refrigerant
Low refrigerant levels change both the coil temperature and the pressure of any component containing refrigerant. This makes it easier for coils to collect extra moisture from the air and freeze.
Reversing Valve Issue
The reversing valve changes the direction of refrigerant flow so the heat pump can switch from heating to cooling. Reversing valves can become stuck or develop leaks that split or reduce the refrigerant flow.
Dirty Air Filter
A dirty air filter can be a major source of dust and grime inside the heat pump. The dirt will build up on the coils and eventually freeze them when it obstructs enough airflow.
