Essential DIY Air Conditioner Maintenance Tasks
1. Clean or Replace Air Filters- Frequency: Monthly during peak cooling season or as recommended by the manufacturer.
- Steps:
- Locate the air filter, typically found behind the return air grille, in the blower compartment, or within the air handler unit.
- Remove the filter and inspect it for dirt and debris.
- If reusable, clean the filter with a vacuum or rinse it with water and let it dry completely before reinserting.
- If disposable, replace it with a new filter of the same size and type.
- Benefits: Clean filters improve airflow, enhance efficiency, and maintain indoor air quality.
- Frequency: Annually or as needed.
- Steps:
- Turn off the power to the air conditioner.
- Remove any debris, leaves, or grass clippings from around the outdoor condenser unit.
- Use a coil cleaner or a mixture of mild detergent and water to spray the coils.
- Allow the cleaner to sit for a few minutes, then rinse thoroughly with a garden hose.
- Be gentle to avoid damaging the fins on the coils.
- Benefits: Clean coils improve heat exchange, enhancing the system’s cooling efficiency.
- Frequency: Annually.
- Steps:
- Turn off the power to the air conditioner.
- Access the evaporator coils, usually located inside the air handler or furnace.
- Use a soft brush or a coil cleaning spray to remove dust and debris from the coils.
