There are some very important things that you should do to extend the life of your air conditioner and keep it working at peak efficiency at all times. One of the most important things that you can do is change your air filter every three to six months.
Many factors determine how often air filters should be changed. Equipment efficiency declines if you wait too long and operating costs increase. Replacing your air conditioner filter too often can be a waste of your hard earned money, especially if you are using an expensive type of filter. A possible solution to this is to use electrostatic filters which you clean and reuse.
It is important to keep in mind that the more efficient your air conditioner filter is the more often it will have to be cleaned or replaced. For most people, pleated filters will do an adequate job. These filters are ten to sixty percent efficient and some manufacturers claim even higher efficiencies.
Pleated air conditioner filters should be changed every three to six months depending on how dusty it is where you live. If you live in an area with lots of dust then your filter may need to be changed every couple of months.
