Every air conditioner contains an air filter designed to protect the system from any dust and debris that might come its way. The air flows through the filter and into the air conditioner, while any contaminants it carried become snared in the fibers. This works quite well, with one exception: the air filter has no way to get rid of the contaminants that it collects. For this reason, it must be cleaned out every three months or so in order to keep functioning. If this does not happen, it will start to cause some serious problems for the air conditioner. Read on to find out more.

The Evaporator Coil

The evaporator coil is the part of the air conditioning system that actually siphons heat out of the air. The coil evaporates refrigerant in order to absorb heat, then sends the refrigerant gas to the condenser coil to be condensed back into liquid. The temperature around the evaporator coil is always dropping during operation, and condensation forms on it as the air is cooled past the dew point. Normally, the flow of warm air from the ducts maintains a temperature balance. If the air filter is not cleaned out often enough, though, it will become clogged and cut off the flow of air to the coil. That’s when problems start to occur.

Ice

If there is no warm air flowing to the air conditioner, the evaporator coil will become cold enough to freeze the condensate on it, forming ice. The ice will prevent the system from properly cooling your home, and will eventually spread to other parts of the air conditioner. This will cause the entire air conditioner to break down eventually. So make sure that you or a trusted professional clean out the air filter every three months.
