The purpose of an Air Filter is to trap dirt, dust and debris. As your air conditioner is cycling, your unit sucks the air in, runs through the coil then returns the air through the ducts around your home to each room. However, if your air filter is not properly changed on time, then you run the risk of clogging or blocking your coil. Once that happens, you will need to hire a professional to clean out the coil with special chemicals.
So how do you know when it is time to change your air filter? The average answer is usually 1 to 3 months. However, your air filter should be dirty when you are changing it. You should be able to see a little build up or a thin layer of debris that is on the filter. If for some reason when the time is due to change it and it still looks new, then you may want to examine a few things to see why. Here are a few suggestions you may need to look over:
Inspect your filter to ensure that it fits properly. By having gaps or spaces around your filter will allow the air to circulate around the sides instead of being pulled through the filter.
Check the labels on the filter you have purchased to ensure that the type of filter you have is the proper one you need for your system. By having a cheap filter, it may not catch all the particles that are being pulled through. You may want to invest in a stronger or more durable filter that is able to handle the system you have.
Sometimes you may want to inspect how you have installed the air filter. Is it put in correctly? Is it upside down? There should be a guideline or arrows that will inform you on how you should install the filter.
The best way to fully understand how and when to change your air filter is to ask your Air Conditioning specialist. When you have your maintenance checks or even after a newly purchased system, your technician will be able to give you the proper information regarding your system on when to change your air filter.
