The main purpose of the air conditioning filters is to keep the system components clean. Air filters in your air conditioner provide you with clean and fresh air for breathing.  If the air filters is unchanged and unclean for a long time, it can:

•    Increase the consumption of the blower
•    Reduce cooling
•    Cause compressor failure
•    Reduce the life of the air conditioner

The most important maintenance task that air conditioners need is regularly cleaning of the air conditioning filters. Air conditioners whose filters are changed at regular intervals run more efficiently and do not consume much energy for operating.

If the air filters become dirty, they begin to restrict the air flow and even cause the evaporator coils to ice up. The operating efficiency of the air conditioner is reduced and the air conditioning unit does not maintain the desired room temperature.

You should clean the filters of the air conditioners whenever you feel that they are not working properly. There are many ways that you can maintain your air conditioner in a proper way so that it can perform at its peak level.

The frequency of cleaning your filters depends on your usage. It can range from 1 to 2 months for most homes and a couple of weeks in offices.  You should never wait for the entire filters to be matted with dust, so replace them as soon as possible.
