Why Is My Heat Pump in Rockledge, FL, Frozen?

A heat pump can provide your Rockledge, FL, home with efficient heating and cooling, but it can also freeze up in certain circumstances. The consequences can range from inefficient operation to total system failure. Learn the potential causes of why your heat pump might be frozen to prevent damage and maintain proper performance.

Lack of Airflow

Insufficient airflow can make a heat pump freeze because restricted airflow keeps the unit from effective heat absorption and transfer. Ice can then form on the coils because of blocked vents, dirty air filters or blower fan issues. Routine cleaning and air filter replacements every two to three months help prevent vent obstructions that lead to this issue.

Low Levels of Refrigerant

Refrigerant is crucial for a heat pump to transfer heat. Low refrigerant levels can throw off the system’s pressure and make the coils freeze. While refrigerant leaks are common culprits, only licensed service technicians should handle them.

Outdoor Unit Complications

Your HVAC maintenance needs to include the outdoor unit, especially when it’s colder outside. Ice, debris and dirt buildup on a heat pump’s outdoor equipment can prevent heat exchange. Have a service technician verify the defrost cycle is working right; this is specifically in place to help melt any accumulated ice.

Component Malfunctions

Sensors and the defrost thermostat can go faulty and cause your HVAC system to freeze up. These components regulate a heat pump’s capacity to prevent ice accumulation. Should they fail, the system might not start its defrost cycle when needed.

A frozen heat pump needs prompt attention to keep you comfortable in your home all year. Routine maintenance and inspections can prevent many of these circumstances so that your heat pump operates efficiently.
