Is Your Air Conditioner Leaking Water? Check These 3 Things

Air conditioner leaking water? Check these 3 things.

As the owner of Air Hawk Heating and Cooling, I understand it’s frustrating when you have an air conditioner leaking water in the middle of a hot summer. Most homeowners don’t know how easy it can be to fix this problem. That’s why I’ve put together this helpful troubleshooting guide to help you inspect your leaky AC. Then you’ll know if you can solve it easily on your own or if you need to call one of our repair specialists.

What Should You Do When You Have an Air Conditioner Leaking Water?

There are three things you need to check when ac starts to leak water:

Look at the overflow drain pan.

This drain pan should collect any condensation coming from your AC unit, so use a flashlight to look for cracks or holes in it. Don’t forget to check the corners, the outside edges and any wet spots. If you find a very small hole, then remove the pan and seal the hole with epoxy. However, that’s a temporary solution. You may be better off getting a new pan, especially if it’s a very big leak.

Is dirt clogging the air filter?

Your fix could be as simple as replacing the AC’s air filter. A lot of filters don’t last for more than a couple of months [1]. During the hot season when you have your AC unit blasting all day, make sure to check the filter once a month. Dirty filters are nothing to mess around with because they can cause bigger problems. Once a filter is very dirty, it starts to cause an icy buildup on your AC’s evaporator coils. That melting ice will lead to bigger AC leaks.

Check for anything plugging up the condensate line.

The condensate line is what you call the part connecting the overflow pan to the outside of your AC unit or to a drain pipe. The job of the condensate line is to stop the overflow pan from flooding with condensation from your AC unit. A clogged line forces water to spill over the overflow pan. Newer AC units have water-overflow cut-off switches built in, and they will automatically shut down your AC upon detecting a clogged condensate line. The purpose of this cut-off switch was to prevent water damage to your home. If your AC shuts off suddenly when everything else seems fine, then this clogged line is likely to be the problem.

How do you fix a clogged condensate line?

If you have a wet and dry vacuum handy, then you can use that to suck out the clog in the line. You can also use a hand pump that can either suck it out or blow it out. Even if you don’t have a blocked line now, it’s in your best interest to prevent it from happening by cleaning out the line regularly.

I also recommend that you prevent mold and mildew from growing in your AC by flushing the line with bleach once every six months. Do it after you’ve removed any blocks in the line.

Our high humidity levels in Florida encourage mold to grow anywhere and everywhere it can. Florida home inspectors commonly talk about how they always check AC units to make sure all of the air ducts are dry and clear. Mold can grow quickly inside a leaky AC unit with too much condensation. Then that mold becomes airborne, blowing and spreading mold through the air of your entire house. It can make people sick when they inhale microscopic mold spores in the air. Those who already have respiratory problems or weak immune systems are especially vulnerable.

For example, illnesses caused by or made worse by mold in an AC unit include mycotoxin-induced pneumonia and lung problems. That’s because you quickly inhale the microscopic mold particles from your AC without realizing it. Then the mold goes straight into your respiratory system.
