Why Your AC Coils Keep Freezing Up
Have you noticed that there is ice building up on your air conditioner? You may not think it is anything serious. After all, an AC is supposed to produce cold, right? Unfortunately, ice on your air conditioner is indicative of a problem. It should not be making ice at any point because that is not how it cools your home. So if you are seeing ice buildup, it is a problem. If you have noticed ice on your air conditioner, there are three main causes:
Dirty Air Filter
This is really the best-case scenario. If you haven’t changed your air filter in a long time, it is definitely dirty. If it is causing ice to build up on the coils, then it is so dirty that it is severely restricting air flow. If you can remember changing your air filter in the last year, this is probably not the cause.
Similar to a dirty filter, if your ducts have been crushed, clogged, or otherwise restricted in one area, it is restricting air flow. This can manifest in ice building up on the coils because the air is not circulating properly. You will also likely notice cool air discrepancies in the home.
This is the most serious cause of ice buildup and a very serious problem with your unit overall. If the refrigerant levels are low due to a leak, it will make it difficult to draw heat out of the air. This means the coils get too cold and freeze. As refrigerant is circulated on a closed loop, it should never get low unless it is leaking. When this happens, you want to contact an HVAC technician right away as your system is not only compromised, but refrigerant isn’t exactly a healthy addition to your yard.
