Air Conditioner condenser coils capture heat from the air inside your home, and tend to collect dirt and debris easily when in regular use. Regular, bi-monthly coil cleaning with Multi-Purpose ADVANAGE 20X Wonder Cleaner during warmer months will keep your AC unit in great working order for years to come. These steps can also be used to clean compressor coils in the outside cabinet of your AC.
DIRECTIONS:
- Turn off the AC at the thermostat and shut off power to the condensing unit.
- Remove outer case and caging. Remove the bolts that are attaching the lid to the rest of the condenser, avoiding the bolts that hold the fan to the lid. If your air conditioner's fan assembly is at the top of the unit, be careful not to stretch or damage any wires. If you can't proceed without doing this, contact a professional.
- Clear out debris and broken fins. Remove any broken aluminum fins (aluminum fins improve heat transfer) as well as leaves, dirt or dead insects that have gotten into the unit. This helps prevent corrosion and increases airflow.
- Spray out the unit. Use a hose to spray out your AC unit, without spraying the disconnect or the electrical components inside the access panel.
- Spray the coils down with Multi-Purpose ADVANAGE 20X Wonder Cleaner. Cover the condenser coils entirely with the cleaner. Let the ADVANAGE 20X Wonder Cleaner sit 10-15 minutes to penetrate heavier soils, and then hose it down again. After the coil cleaner has dripped off the coils, examine the coil surfaces for any areas that may need another application, and repeat this step as necessary.
- Rinse and dry your AC. Spray rinse water from the inside outward, clearing away any remaining residue. Dry off with a clean cloth or paper towel.
- Inspect coil fins for damage: Carefully straighten any bent coil fins.
- Reassemble the air conditioner: Reassemble your air conditioner now that your coils are clean, and reconnect power to the condensing unit.
