A common problem that many people experience with their air conditioning system is that their AC coil may freeze up. A frozen AC coil can cause a number of issues with your HVAC equipment, not to mention potential water damage. And of course, your system won’t be able to properly cool the home if the coil is frozen — as airflow through the system will be significantly restricted.
Curious about what to look for, why a frozen AC coil happens, and what to do next? Re4d on!
Frozen AC Coil: What To Look For
A few things you might notice if your AC coil is frozen might be:
- Little to no airflow coming from vents
- Water pooling around the unit
- Visible condensation and/or ice on the unit
Why Is My AC Coil Frozen?
One reason why there could be ice buildup on your AC coil could be as simple as a dirty air filter… in that case, it would be a quick fix with a filter replacement. Why does switching out the filter help with frozen coils? Dust, dirt, and debris can block the air from properly flowing through the system and your ducts. This, in turn, causes the system to cool down to freezing temperatures. A few other common reasons for a frozen AC coil could be a refrigerant leak, a plugged/dirty coil, or even a bad blower motor.
What To Do If Your AC Coil Is Frozen
If you are experiencing any of these issues, the very first thing you should do is turn off the system to allow time for the unit to thaw out.
The main reason for this is that it’s not possible to properly diagnose and repair an air conditioning system when the coil is frozen up. We recommend allowing 24 hours for the AC coil to thaw before a technician visit.
Also, some homeowners have found that when their AC coil is freezing up — turning the system off and allowing it to defrost, then turning the system back on — can resolve the problem in the short term. However, we don’t recommend that you do this, as it’s likely your AC coil will continue to freeze up each time the system is turned back on for cooling. While it may be a short term bandage, it does not heal the underlying issue in the system that is causing the coil to become frozen. It may also exacerbate any damage to the system and increase the chances of failure or water damage.
