Maintaining Air Conditioner Filters

While an air conditioner makes your home more comfortable, the unit itself does require some basic
ongoing maintenance to help it function efficiently and effectively throughout its lifespan.

The most important maintenance task is to routinely clean or replace filters. Clogged, dirty filters block
normal airflow and significantly reduce the system’s efficiency. Installing a clean filter will lower your air
conditioner’s energy consumption.

For central air conditioners, filters are generally located somewhere along the return duct. Common
locations to find them are in walls, ceilings, or in the ductwork near your furnace. Room air conditioners
have filters mounted in the grill that faces into the room.

Filters come in a variety of types and efficiencies, and some are reusable, while others must be
replaced. Filters need more frequent attention if the air conditioner is in constant use, is subjected to
dusty conditions, or if you have fur shedding pets in the house.

Clean or replace your air conditioning system’s filters every couple of months during the cooling season.
