HOW TO CLEAN CONDENSER COILS


What You Need

  • Garden hose or some other clean water source
  • Small broom or hand brush
  • Fin comb (available at hardware stores)

Home air conditioners get a heavy workout during hot summer months. Condenser coils are one of those components that can make or break your electric bill. Dust and dirt buildup are the number one enemy of your air conditioning unit, impeding heat transfer and keeping your AC from working efficiently.


You can avoid higher energy costs and the potential need to replace your air conditioner entirely by replacing your air filter every four months, and giving your condenser coils a good cleaning with Simple Green Foaming Coil Cleaner.

DIRECTIONS:

Check your air conditioner warranty before cleaning.

  1. Turn off the A/C and shut off power to the condensing unit. Condenser coils should be cool before cleaning.
  2. 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.
  3. Clear out debris and broken fins. Use a small broom or hand brush to 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 increase airflow and cooling.
  4. Spray out the unit. Use a hose to spray your A/C unit from the inside outward, without soaking the disconnect or the electrical components inside the access panel.
  5. Dilute 1-part Foaming Coil Cleaner with 3-parts water. [Example: 1 quart cleaner to 3 quarts water]
  6. Apply cleaner to coils. To ensure foaming, use a pressurized, pump-up, or spray applicator. Avoid spraying onto electrical wires or connections.
  7. Product is self-rinsing on condensate-producing coils. Otherwise, damp wipe or clean with water.
  8. Inspect coil fins for damage. Carefully straighten any bent coil fins with a fin comb.
  9. Reassemble the air conditioner now that your coils are clean and reconnect power to the condensing unit.
