How to Clean AC Evaporator Coils Inside Your House

Maintaining your AC evaporator coils is crucial for keeping your HVAC system running efficiently. Dirty coils can reduce cooling efficiency, increase energy bills, and even lead to system malfunctions. Fortunately, cleaning your AC evaporator coils inside the house is a task you can tackle with the right tools and guidance.

Tools and Materials Needed:

  • Screwdriver
  • Soft brush or coil cleaning brush
  • Compressed air
  • Coil cleaner spray (non-corrosive)
  • Protective gloves and goggles
  • Clean cloths or rags

Step-by-Step Guide to Cleaning AC Evaporator Coils:

  1. Turn Off the Power
    • Before starting, turn off the AC unit from the main power supply to ensure safety.
  2. Locate the Evaporator Coils
    • Open the access panel of your HVAC system using a screwdriver. The evaporator coils are usually located inside the air handler or near the blower fan.
  3. Inspect the Coils
    • Check for visible dirt, dust, and debris. This will help you determine the level of cleaning required.
  4. Use a Soft Brush or Compressed Air
    • Gently remove loose debris and dust using a soft brush or compressed air. Avoid damaging the delicate fins.
  5. Apply Coil Cleaner
    • Spray a non-corrosive coil cleaner onto the coils. Ensure even coverage and let it sit for the recommended time (as indicated on the product label).
  6. Rinse or Wipe Down
    • If the coil cleaner requires rinsing, use a damp cloth or lightly spray water to remove the cleaner and dirt. For no-rinse cleaners, simply wipe the coils with a clean cloth.
  7. Reassemble the Unit
    • Once the coils are clean and dry, reattach the access panel and turn the power back on.
  8. Test the System
    • Turn on your AC and check for improved cooling performance.

Maintenance Tips for Cleaner Coils:

  • Change your air filter regularly (every 1-3 months).
  • Schedule annual HVAC maintenance with professionals.
  • Keep the surrounding area of the HVAC unit clean and free of dust.

Benefits of Clean Evaporator Coils:
