Water has started to pool around your central air conditioner’s inside unit and you have no idea why. First, you should turn off your air conditioner because this water could harm the electronic parts of your AC and cause water damage to your home. Then you should contact a professional AC repair person for help. If you want to understand the cause of this problem before calling a professional, read this article. Why water forms in a central air conditioner indoor unit Part of your air conditioner’s job is to pull humidity from the air. The inside unit’s blower pulls in hot, humid air through the return grille and over the inside unit’s cold evaporator coil (pictured above) to cool the air down. When that happens, condensation/droplets form on the evaporator coil. It’s just like when water droplets bead up on a glass of ice cold water on a hot summer day in Georgia. That water on the evaporator coil falls into a sloped drain pan and down a condensate drain line like a slip n’slide.

That drain line (usually a PVC pipe) either exits out the home (usually near the outside unit) or into your plumbing. OK, so now you have a general idea of how the water forms and the parts involved. If there’s an issue with any of these parts, that’s why the water is forming around the inside unit. Here are a few common problems that are causing the issue you’re having. Clogged condensate drain line or rusted condensate drain pan If the drain line gets clogged by dirt, insects, mold, or anything else, the water has nowhere to go but back into the home. (Some home’s have a secondary drain line but that may also be become clogged.) Use wet-dry vacuum to suck out the obstruction from the outdoor PVC condensate pipe. Also the root of the problem may be a dirty evaporator coil. The dirt will mix with the water and fall down into the pan, clogging the drain. Have a professional clean this coil annually as part of an annual AC maintenance visit. Also, the drain pan may be rusted through and is falling onto the floor and causing  damage to your home.

So you’ll need to replace that. Note: Your air conditioner may have a secondary drain pan to catch the water. This pan has a float switch that turns off your air conditioner to prevent water damage.Mazda 3 Tire Lock Key If you have a newer air conditioner, the problem may be installation related.

You’ll need a professional to examine the condensate trap to see if it has been designed properly and fix it if necessary. Open the blower door of your inside AC unit. Is the evaporator coil covered in ice? When that frozen evaporator coil melts there may be so much water that it flows over the drain pan and then onto the floor.

There are 2 common causes of a frozen evaporator coil: To defrost the evaporator coil, turn the air conditioner off. Then turn the blower from “auto” to “on.” The fan should melt the ice slowly enough for the drain pan to handle all the water. In the meantime, you should call a professional AC repairman to check your air conditioner to make sure it’s is working properly and ensure nothing was damaged. Just a few of many issues… There are other causes of water pooling around an inside air conditioning unit, but these are some of the most common.Contact us online or call us at (770) 443-1821.

Nearly 90 percent of all central-air service calls are related to leaks. Although these leaks tend to be relatively small, if left unchecked they can cause a tremendous amount of damage, especially if the air handler is installed above a ceiling and can drip downward. But most homeowners don't realize that a vast majority of leaks can be easily repaired without calling a service technician.There are main reasons a central A/C system leaks. First, there's a crack or hole in overflow drain pan. Second, the air filter is clogged with dirt. Third, the condensate line is plugged up.The first cause—the overflow pan—is easily detectable by simply using a flashlight. The pan is a piece of equipment that catches any condensation from the A/C unit; if you're noticing a leak, carefully inspect the overflow pan for damage. Check each corner, along the outside edges, and, of course, directly above the wettest spot. Small holes and cracks can be patched with epoxy glue, but it's usually best to replace a damaged overflow pan.

The second culprit—a clogged filter— can be avoided by changing the A/C unit's air filter on a regular basis. Most filters are designed to be used for one or two months, but you should inspect the filter every month during the cooling season. If the filter appears dirty, replace it immediately. A dirty filter will cause ice to form on the unit's evaporator coils, and when that ice melts, it drips water.The third reason—a stopped-up condensate line—is the most common cause of A/C leaks. The condensate line drains condensation from the overflow pan to the outside or directly into a drainpipe. When the line is clogged, water backs up and floods the overflow pan. Another reason to keep the condensate line clear is that most modern A/C units are equipped with a water-overflow cutoff switch, which automatically shuts down the A/C system if it detects a clogged condensate line. The switch helps prevent water damage, which is good, but most homeowners don't know why their air-conditioning system suddenly shuts down and they call a service technician.
