How to Fix a Water Leak From a Mini Split AC Indoor Unit In 8 Easy Steps

Fortunately, if there is a clog in your drainage pipe, there is an easy way you can fix it with minimal time and effort.

Materials

  • Phillips head screwdriver
  • Electrical tape
  • A bucket
  • A vacuum with a hose attachment

Directions

Step 1. Turn your air conditioner off

Before you can address the clog, make sure your air conditioner is turned off.

Next, open the front panel and remove the filters. If you notice the filter are dirty, now is a good time to vacuum them or wipe away excess dust.

Step 3. Remove the plastic cover
