Heat Pump Freezing Up in San Angelo, TX
Some frost on an outdoor heat pump in winter is normal, but a thick ice buildup that does not clear is a problem. It can stop the system from heating and damage the compressor.
Common Causes
Defrost Cycle Failure
If the defrost cycle fails, ice builds up and never clears.
Low Refrigerant
Low refrigerant can cause the outdoor coil to drop below freezing and ice over.
Dirty Coil or Filter
Restricted airflow over the coil can cause freezing.
Airflow Blockage
Blocked outdoor airflow from debris or snow can cause icing.
