- Procedure:
- Locate the Filter: The filter is usually located in the return air duct, either near the air handler or in a wall or ceiling vent.
- Remove the Filter: Carefully remove the old filter.
- Inspect the Filter: If it’s a disposable filter, discard it. If it’s a reusable filter, vacuum it or wash it according to the manufacturer’s instructions.
- Install the New/Cleaned Filter: Insert the new or cleaned filter, ensuring the airflow direction is correct (usually indicated by an arrow on the filter).
2. Coil Cleaning:
- Frequency: Coils should be cleaned at least once a year, preferably before the cooling season begins.
- Types of Coils:
- Evaporator Coil (Indoor Unit): This coil absorbs heat from the air inside your home.
- Condenser Coil (Outdoor Unit): This coil releases heat to the outside air.
- Procedure:
- Evaporator Coil:
- Turn off the AC unit and disconnect the power.
- Remove the access panel to the evaporator coil.
- Use a vacuum cleaner with a brush attachment to remove dust and debris.
- If the coil is heavily soiled, use a coil cleaner specifically designed for AC units. Follow the manufacturer’s instructions carefully.
