How to Repair an Air Conditioner Freon Leak

What You'll Need
Water Hose
Spray Nozzle
Leak Sealant or Compound

An air conditioner repair involving a Freon leak can be completed following these steps that can assist you in the repair. This type of repair should be part of the regular maintenance associated with an air conditioner unit and performed at least annually, either prior to first use or when it has been put away for colder months.

It should be noted that most newer air conditioner units no longer use Freon as a cooling refrigerant because of the harm that it does to the environment. An older air conditioning unit that you own that still uses Freon should eventually be replaced in favor of a more green and environmentally friendly model. Before this replacement a Freon link should be addressed immediately to prevent any further environmental damage.

Step 1: Remove Unit from Window

Remove the air conditioner unit from the window and place it on a hard, firm surface such as wood or concrete. Do not place the air conditioner on the ground or an earth surface with leaves or dirt.

Step 2: Remove the Outer Cover

Use the screwdriver to take off the outer housing of the air conditioner. Place the housing cover to the side where it will not become damaged with the screws that you removed.

Step 3: Remove Debris and Bacteria from Drain Tray

While you have the air conditioner open before addressing the Freon leak remove all debris and spray the air conditioner with water using the water hose and spray nozzle. All of the debris that collected in the drain tray near the vent coils should be removed.

Step 4: Locate the Freon Leak and Seal

Remove any air filters insider the air conditioner unit and locate the air compressor. Evidence of the area where the link took place should be easy to locate. Apply a stop leak compound that can be purchased from an auto supply store. The leak sealant or compound should be applied as instructed on the can.

Step 5: Replace the Cover and Test the Air Conditioner

Place the cover back on the front of the air conditioning unit and place it back into the window unit. Operate the unit and watch to see if any leaks that developed and observe for any further leaks. If the air conditioner continues to leak, remove the cover and spray the inside with a leak sealant again. If this does not rectify the situation, call a qualified repair technician to service the unit.
