Knowing how the air conditioning (AC) unit in your Spring Hill, Florida, home works and what can go wrong will help you to better understand the importance of maintenance and how to keep your system running more efficiently. One common problem that can occur with your AC system is the evaporator coil freezing.
Why Your Evaporator Coil May Freeze
Your AC unit cools your home by expanding refrigerant in your evaporator coil, causing it to cool down quickly. The cooled coil will then come in contact with the warm air in your home where the refrigerant will absorb the heat before it gets transferred outside. For the coil to operate properly, there needs to be the right amount of airflow and refrigerant levels. Some of the top reasons your coil may freeze include:
- dirty filters
- broken fans
- low refrigerant
- blocked condensate lines.
Signs That Your Evaporator Coil May Be Frozen
If you are having problems with your AC unit, some of the signs below may point to a frozen coil as the culprit:
- ice around the outdoor refrigerant line
- moisture or condensation around the air handler
- the drain pan is full or overflowing.
What to Do if Your Coil Is Frozen?
The first step if your evaporator coil freezes is to shut off your system. Failure to do this could result in compressor failure. You should then contact an HVAC technician. They will need to identify the underlying problem to ensure it is fixed and in order to make sure it is functioning again. While waiting for the technician to arrive, you will need to clean up any water damage while the ice is melting. Once we fix that issue with your system, you should set up a regular maintenance plan to avoid the problem from occurring again in the future. Preventative maintenance can address common issues that result in frozen coils.
