What You'll Need
Screwdriver
Bleach
Cup Measure
Water Hose with Nozzle Attachment
Leak Sealant

Fix any air conditioner compressor leaks as part of the regular maintenance associated with your AC unit. Follow these steps at least annually, either prior to first use or when it has been put away for colder months.

Step 1: Take the Unit Out of Window

Remove the air conditioner unit from the window and place it on a hard, firm surface. If necessary, place the air conditioning unit on top of old boards or on a concrete slab.

Step 2: Remove the Outer Cover

Use the screwdriver to remove the outer housing of the air conditioning unit. Place the housing to the side where it will not become damaged while you work on the air conditioning unit.

Step 3: Remove Debris and Bacteria from Drain Tray

Pour a cup of household bleach into the drain tray and allow to sit for 5 to 10 minutes. This will work to remove bacteria and other debris that has collected inside the air conditioner and settled into the tray.

Step 4: Spray Inside of the Air Conditioner

Remove an filters insider the air conditioner unit and take a water hose with nozzle attachment to spray the inside.  Use a moderate stream in order to dislodge any other debris that is inside the air conditioner unit or has collected around the compressor or coils.

Step 5: Add an Additional Cup of Bleach

After spraying the inside of the air conditioner, add another cup of bleach to the drain tray and allow it to sit for another 5 to 10 minutes.  Spray the inside of the air conditioner and allow to dry in the sun for up to an hour. Once dry, place the cover back on the front and reinstall the air conditioner.

Step 6: Test the Air Conditioner

Run the unit and watch to see if any leaks have developed or if any observed leaks have disappeared.  If the air conditioner continues to leak, remove the cover and spray the inside with a leak sealant that can be purchased at an auto parts store. This product should be applied as instructed and should seal any leaks after the cleaning process has been completed.
