A Central air conditioner or cooling system may sometimes leak water due to clogging of the drain pipe. All kinds of central AC’s produce condensate and AC's will have a drain pan to hold the condensate. A drain pipe is attached to the drain pan which empties the condensate outside. At times due to the clogging of the drain pipe, water may leak from the AC. To find if your AC is leaking you need to look for certain aspects.
Step 1: Checking the drain pan
Checking the drain pan regularly will help you identify if your AC is leaking. Open your AC’s cooling coil cabinet and see if the drain pan is flooded. If it is, then you can be sure that your drain pipe is clogged and it needs to be cleared.
Step 2: Clearing the drain pipe
You can clear the drain pipe by using bleach and water. Otherwise use a pump and water to push water through the drain pipe.
Step 3: Checking for water stains
Check for water stains on the floor around the AC equipment and below the ‘A’ frame cooling coil. This will help you know if your AC has been leaking.
