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.coleman hvac package unit Here are a few common problems that are causing the issue you’re having.car air conditioning repair rochester Clogged condensate drain line or rusted condensate drain pan99 jeep wrangler ac control unit 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. If you have a newer air conditioner, the problem may be installation related. An improperly designed condensate trap will stop the condensate from draining. So all that water builds up in the drain pan and overflows into your home, causing water damage. 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.

Here’s a common question we get during Florida summers, “Why is my AC leaking water inside my home? But first, turn your AC’s thermostat to “Off” to prevent further damage to your home.To understand why this is happening, you need to know how water forms on your AC in the first place. Your AC’s inside unit contains the evaporator coil (pictured on the right) that cools the warm air blown over it. This causes condensation (moisture) to form on the coil, just like how water droplets form on a cold glass of water on a hot day.The moisture on the coil drips into a drain pan and down a condensate drain line (a white PVC pipe) that leads out your home.So, with all that in mind, here are a few things that cause that water to leak into your home. A clogged condensate drain line is the most common cause of water leaking from your AC into your home.

If the drain line gets clogged with dust, dirt, sludge or mold, that water backs up into your home. In that case, you’ll need to unclog it. There are multiple unclogging methods, like using a wet/dry vac on the condensate line.But the surefire way is to have a professional use a special vacuum to suck the blockage material out. Got an old air conditioner (12-15 years)? The drain pan may be damaged or rusted through, so water just falls right through. You’ll need to replace the pan. Is your furnace and indoor AC unit installed in the basement? If so then there is a condensate pump that pumps the water outside. But if the pump breaks, the water isn’t being pumped outside anymore. You will need to repair or replace the pump. A dirty air filter blocks airflow over the evaporator coil. When that happens, the evaporator coil gets too cold and freezes over. When it melts, it drips an excess amount of water that the pan may not be able to handle.Check your air filter to see if it’s dirty and change it if needed.
