You should replace your air conditioner filters regularly, approximately every 30 days. Newer systems typically use pleated filters, also rectangular filters with a depth of approximately one inch. If you don't have allergies, you should replace them approximately every 90 days, but air conditioning professionals usually recommend them every 45 days for maximum efficiency. Generally, most air filter manufacturers and HVAC companies recommend changing the air filter every 90 days or 3 months.This may change depending on the location of your home (e.g.
dusty and dry climates), if you have pets, and the age of your system and equipment. If you have pets at home, you should consider changing the filter every 60 days or 2 months, and in the case of households with several pets or people with allergies or respiratory conditions, we recommend that you change the filter every 20 to 45 days. Usually, vacation homes or empty houses that aren't used much can wait to change filters every 9 to 12 months.The general consensus is that the more you use your home, the more often you'll need to change your air filter.

An HVAC filter will only last one to three months on average, so it's important to keep track of the date you installed them.If you wait too long to change the filter, indoor air quality will be affected.
Changing the air filter will help keep the air conditioner parts clean and prevent them from wearing out. In addition, if the air filter is not replaced accordingly, it can increase a homeowner's energy bill, as clogged filters make the system work harder by circulating air.During allergy season, air filters can work overtime to remove allergens, dust, and other debris that circulate through the heating and cooling system. The air conditioner air filter is responsible for removing most of these particles from the air, which can affect indoor air quality and the efficiency of the entire system. Air filters trap pet hair, dust, and other irritating particles so that the air conditioning system returns fresh, clean air to your home.By removing the air filter from the air controller and holding it close to a light source, you'll be able to see if it's dirty or clogged; if you can't see the light through the filter, it's definitely time to change it.
