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.can you run an ac unit without a filter If you have a newer air conditioner, the problem may be installation related. does hvac unit workAn improperly designed condensate trap will stop the condensate from draining. mini ac unit no windowSo 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.

Let's dive in a little deeper and see how these things relate to each other.If you carefully look at your air conditioning unit, you'll probably see a label like this : The power rating printed on such a label is when the AC is under a stable load, the current is constant, the compressor is working, there's no back emf being produced int the induction coils., and above all the supply voltage is exactly equal to 230 volts at 50 Hz.In this stable state, the AC unit is consuming 1.5 units of electricity per hour. That said, not always is the compressor running. If you AC has a thermostat and a temperature setting, once the ambient room temperature reaches to the set limit, the compressor shuts off and only the circulating fans work.In this case the power consumption is almost equal to a ceiling fan, with my test bench, I got readings around 0.3 amps at 230 volts.

That is equal to 0.06 units per hour, almost equal to a 80 watt incandescent bulb.Another test I conducted : Under extreme load, at a room temperature of about 32 degree Celsius, the power consumption rose to almost 1.8 units per hour, or 1800 watts.   How do you calculate your power consumption : The commercial unit of electricity is kWh, also called as BTU (Board of trade Unit), which equals to one kilowatt load used for 1 hour.Units = Power in Watts * time in seconds / 3600000Units = Power in Watts * time in hours / 1000Units = Power in kilo Watts * time in hoursYou can guess the power consumption by these steps : For while the compressor is working :For while the circulating fan is working : Try this for the average time you use your air conditioner in a day, and add the two to get the daily units consumption. Multiply this with the cost of 1 unit of electricity (around Rs. 6) and you'll get the bill for a single day. Multiply by 30 to get the monthly expenditure.I use my AC unit for around 14 hours a day, at 24 degree Celsius.During the 14 hours cycle, my compressor works for about 4 hours, while for the rest 10  hours, only the fan works.
