How often do you change the air filter in your AC? If it’s less than every 3 months you may have a problem! Let's see why.
Every AC includes an air filter, which sits in the return duct for the system. All air that flows into the AC moves through this filter, which catches any dust that can damage the system. This means that the filter needs to be cleaned every few months in order to keep operating properly. If that doesn’t happen, the filter will become clogged and the problem will start.
If the air filter becomes clogged, the flow of air to the evaporator coil will stop. This will cause the temperature of the air around the coil to drop below freezing, resulting in ice forming . While the evaporator coil is frozen over, it will be unable to siphon thermal energy from the air in the ducts. This will result in the output of the air conditioner dropping significantly. The ice can also spread to other parts of the AC, causing further damages.
