Step 1:

Start by disconnecting your A/C unit from its power source. Remove the plastic filter holder or panel – it should snap off, but check first and ask your friend to help you get it down from the wall.

Step 2:

If your unit is window-mounted, you’ll also need to unscrew the mounting frame and case. Make sure you pay attention to which screws go where so it’s easier to put it back together after you’ve finished your A/C duct cleaning.

Safety Warning

You should only clean air conditioning appliances yourself if it’s safe and permitted in the owner’s manual. Read the manual carefully first before doing any cleaning or maintenance.

Step 3:

Use your fin comb to straighten out any bent fins. Wear thick gloves while you’re doing this – those fins are sharp!

Step 4:

Vacuum any dust, cobwebs and other debris away from both coils, and then spray them both with air conditioner coil cleaner. The foam will need a little while to act. Check the manufacturer’s instructions, and don’t leave it on for longer than recommended.

Step 5:

Use the rags and household cleaner to wash the fan blades. Double check to make sure the unit is unplugged before beginning this step and wear thick gloves for protection.

Step 6:

Check for oiling ports – they may have plastic or rubber caps – and use a few drops of electric motor oil to grease it up

Step 7:

Wash or replace the filter

Step 8:

Put everything back together and mount it again

There you have it: a complete guide to cleaning your air conditioner at home. Although air conditioner maintenance might seem daunting, it’s actually very easy once you know what you’re doing – and it could even help to prolong the life of your A/C.

Key Steps

  • Get help with the heavy lifting

  • Keep note of which screws belong where

  • Protect your hands whilst cleaning the fins

  • Vacuum away any solid matter

  • Use the right cleaner for the job
