You have a puddle on the floor. With a little detective work, you’ve traced the puddle to your air conditioner leaking water. What should you do – should you try to fix it yourself?

The answer to that question is, “it depends.” Sometimes, you can fix an air conditioner leaking water, while other times, the task is best left to the pros. Read on to learn what can cause air conditioner leaking and when you should call a technician.

Why Do Air Conditioners Leak Water?

Air conditioners leak water because condensation forms on the evaporator coil. The evaporator coil is part of the air conditioner that absorbs the heat from the air in your house.

Its role is to hold the chilled refrigerant the compressor has moved into the coil. As the air from the blower fan moves over the coil, the refrigerant removes heat from the air in your home.

During this process, moisture forms on the evaporator coil. That moisture drips down onto a drain pan, then it travels down the condensate line out of your home. Sometimes, conditions arise that lead to leaks. You may want to also check on your furnace for a leak too.

1. Your Air Filter Is Dirty

A common cause of air conditioners leaking water is dirty air filters.

When air filters get dirty, they block the air flow over the evaporator coil. The evaporator coil then freezes over. When it melts, there can be too much water, which can lead to leaks.

You can solve that problem by changing your air conditioner’s filters. Experts recommend that you change them every one to three months.

2. Dirty Coils

Dirty coils are another reason for an air conditioner leaking. The coils we’re referring to are the evaporator coils.

Over time, rust, dirt, mold, or debris can stick to your coils. As a result, water can’t stick to the coil very well, and it drips onto the ground. A dirty evaporator coil causes other problems too – it makes leaking water dirty and can clog drains.

3. Clogged Drains

A clogged drain is best left to a professional. A technician will know how to remove the clog carefully, without damaging any part of your home. If necessary, the technician will install an overflow shutoff device to prevent this problem.

4. Installation Problems

Improper installation can lead to an air conditioner leaking. Drain pipe fittings might not have been put in place correctly. Over time, they become looser, which allows condensation to drain onto the floor.

Additionally, the unit might not be completely level, or there might be too much pressure. These problems cause leakage, and should be fixed by a professional.
