Steps to Clean AC Coils Inside the House

Follow these steps to clean the AC coils inside your house:

  1. Turn off the power: Before you start cleaning the coils, turn off the power to the air conditioning system to prevent any accidents or injuries.
  2. Locate the coils: Depending on the type of AC unit you have, the location of the coils may vary. Typically, the coils can be found in the air handler unit or inside the indoor unit of a ductless mini-split system.
  3. Remove the access panel: Use a screwdriver to remove the access panel that covers the AC coils. Be cautious and follow safety guidelines when handling electrical components.
  4. Inspect the coils: Carefully examine the coils for any visible dirt, dust, or debris. If the buildup is minimal, you may be able to clean the coils with a brush and vacuum. For heavier buildup, a coil cleaner may be necessary.
  5. Clean the coils: Use a brush with soft bristles to gently remove the dirt and debris from the coils. Be thorough but gentle to avoid damaging the delicate fins. For stubborn dirt, a coil cleaner can be sprayed onto the coils and allowed to sit for a few minutes before rinsing.
  6. Rinse the coils: Use a water hose to rinse the coils thoroughly. Start from the top and work your way down to ensure that all the dirt and cleaner residue are washed away.
  7. Straighten the fins: Over time, the aluminum fins on the coils can become bent or damaged, affecting the airflow. Use a fin comb to carefully straighten any bent fins and improve the efficiency of the coils.
  8. Optional vinegar rinse: For an extra cleaning boost, mix equal parts water and vinegar and gently apply the solution to the coils. Allow it to sit for a few minutes before rinsing with water.
  9. Reassemble and restore power: Once the coils are clean and dry, reassemble the access panel and restore power to the air conditioning system. Check for any leaks or issues before turning the system back on.

Maintenance Tips

To keep your AC coils clean and functioning optimally, consider the following maintenance tips:

  • Change your air filters regularly to prevent dust and debris from accumulating on the coils.
  • Schedule annual professional maintenance to ensure that the entire AC system is clean and in good working condition.
  • Keep the area around the indoor unit free from clutter and obstructions to promote proper airflow.
  • Monitor the performance of your air conditioning system and address any issues promptly to prevent dirt buildup on the coils.

By following these steps and maintenance tips, you can effectively clean the AC coils inside your house and promote the efficient operation of your air conditioning system. Remember to prioritize safety and consult a professional if you encounter any challenges during the cleaning process.
