To give some context…
Your air conditioner removes moisture from your home’s air at the same time it cools it.
This moisture removal process takes place in the air handler (the indoor part of your AC), and the process is outlined below:
Over time, drain pans can become rusted, which causes them to develop leaks and holes. If your drain pan is worn out, that could explain the pool of water you see around your indoor unit.
Solution: Contact a professional to replace your drain pan.
Some AC issues cause the evaporator coil (the part that cools your home’s air) to ice over. When the ice melts, water can overflow from the drain pan and spill into the area around your air conditioner.
The following 2 issues cause an evaporator coil to freeze:
Solution: Follow these steps:
1. Make sure your air filter is clean. A dirty air filter restricts air blowing across the evaporator coil, which can cause it to freeze over. So if your air filter is dirty, change it. If you change the filter and your AC continues to leak water, go to step 2.
If your filter is dirty like the one on the right, it could be causing your AC to freeze over
2. Contact an AC professional to check for a refrigerant leak or clean your evaporator coil.

If your condensate line is clogged or blocked with debris, all of the moisture that’s supposed to drain outside will back up into the drain pan.
Your drain pan can only hold so much water: If too much water enters your drain pan, it will overflow, which causes a puddle of water around the AC.
A clogged condensate line will cause water to overflow from the drain pan, which causes pools of water around your indoor AC unit.
Solution: Contact a professional to clear your condensate line.
If your air handler is located in the basement, you probably have a condensate pump to help push all of the moisture up and out of your home.
Unfortunately, like most mechanical equipment, condensate pumps can and do break down over time. If your pump breaks, then water could overflow from the drain pan into the surrounding area.
Solution: Have a professional repair or replace your condensate pump.
