In Flat Rock, NC, it’s generally mild during the fall. But it can occasionally soar above 80 degrees or drop into the 30s. Therefore, it’s a good idea to keep your heat pump in good working order to deal with fluctuating temperatures. Read on to find out some possible reasons your heat pump could freeze.
Clogged Air Filter
Adequate airflow through the indoor unit of your heat pump allows for proper heat exchange in the evaporator coil. Clogged filters are the primary cause of both bad airflow and the resulting ice formation within the system. You need to change your filter every one to three months. If you have pets in the home, check and change your filter more frequently.
Dirty Evaporator Coil
When dirt collects on the evaporator coil, it prohibits heat exchange in the heat pump. This keeps the refrigerant at very low temperatures, allowing ice to form on the coils.
Low Refrigerant Level
When there’s insufficient refrigerant running through the system, it reduces the surface contact, preventing heat exchange. Because it’s a closed-loop system, low refrigerant means you have a leak. Fixing a coolant leak is a job for a professional HVAC service technician. Never attempt this task on your own as refrigerant is hazardous to human health and the environment.
Insufficient Airflow
While a clogged filter is the leading cause of poor airflow, other problems can cause it as well. Blocked registers are one of these issues that can cause poor airflow through the system. If removing the obstructions doesn’t return adequate airflow, you could have a problem with the blower motor or fan blades that requires professional attention.
