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. 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.how much power do window ac units use Just a few of many issues…home central air conditioner maintenance There are other causes of water pooling around an inside air conditioning unit, but these are some of the most common.how much does it cost to replace ac unit in homeContact us online or call us at (770) 443-1821.

The AC unit is a medium of technology and mechanical components to transfer heat. Written You may be able to rig up something whether the compressor-side air intake and exhaust are piped outside, but the efficiency will be low and you may risk burning out the compressor by working it too hard.If you want something you can install in a small opening, you might consider wheeled portable AC units which come with a flexible duct.If you're still determined to try it, note that window AC units have two sets of air intake & exhaust:the "inside" side that takes air from inside (usually through a large filter on the front), cools it, and blows it back insidethe "outside" side that takes air from outside, heats it (with the heat removed from the cool side) and blows it out the back.On a typical window AC unit the "outside" air comes in through vents on the side and top of the unit and is blown out the coils at the back. So you will need to make sure both of those parts are getting the airflow they need.

And they can't be the same duct, or else you will just get super hot air re-circulating through the unit.Written As you aware Window unit air conditioners are installed in an open window. The interior air is cooled as a fan blows it over the evaporator. On the exterior the heat drawn from the interior is dissipated into the environment as a second fan blows outside air over the condenser. A large house or building may have several such units, allowing each room to be cooled separately.Written I'm unsure of the nature of this question but yes you can.  You can for example cut a hole through your bedroom door and install it through the door.  The back would be facing the rest of the house and you would make your bedroom super cold.  While at the same time dumping the heat into the rest of the house instead of outside.Written it depends very much on the nature of the rooms. But 9 out of 10, the situation wont be a feasible one. If your inside room has one of its walls adjacent to some crawl room or some unused room which is itself well ventilated then yes you can.
