The short answer: If condensation accumulates within the air vent, it can cause water to drip from the AC vents. This is often caused if you have a clogged condensate drain line on your hands. Another sign (and a potentially dangerous one) of a blocked condensate drain is rust on the furnace. Drain line problems & amp; your AC dripping water. Issues with the condensate drain line are the most common cause of an air conditioner leaking water inside the house. If it gets clogged with dirt and debris (which are carried into the line along with the condensate) the backup can cause leaks or a rupture of the line.
Also, depending on the air conditioning system; it is possible to build a simple air conditioner that uses water as a coolant but commercial air conditioners don’t. However, they cool the air and this lowers the dew point. Thus, water vapour condenses out of the air and this is why window air conditioning units drip water.
If the coolant of the air conditioner leaks into your house, it will quickly evaporate into a gas and will be harmful for the occupants. It may cause a number of health problems such as nausea, headache or even asphyxiation in extreme cases. While copper can be unhealthy in high doses, the condensate from air conditioners seems to be low in minerals and dissolved solids. … The water that drips from air conditioners is probably even safe for drinking. (It’s certainly more potable than the drinking water in many countries.)
Water from your air conditioner condensation can be used to water your plants, both indoor as well as outdoor. The condensate is pulled out from the air outside, and therefore does not contain chlorine or any other minerals that may be found in drinking water.
Excessive condensation from air conditioning is a sign you have an ac issue. In this case call Sledge Total Protection and we will be on our way!
The long answer: Listed as top reasons your A/C is dropping.
-Broken Condenser Pump
Try looking into is the condenser pump as it could be broke. To test if it is the condenser pump, you can pour water into the condenser pan, if it works the excess should be pumped out properly. If it’s not able to pump the excess out, check to make sure the pump is getting power. If it gets power, then it’s probably the motor or condenser. Call for an appointment to determine which it is for sure, and correct it.
Note: It is possible that the AC unit leaks more water because the unit was incorrectly installed, such as not being level or having too much pressure.
-AC Unit Installed Incorrectly
AC Units can leak when they have been installed incorrectly. If it is installed so it’s not level, for example. Too much pressure build up can also cause a leak. To determine either of these, start by checking if the unit is level. If it is level, then look for closed vents around your house as this can cause added pressure on the unit.
It is common for newer AC units to have an installation problem over something else. A condensate trap that was improperly designed can prevent drainage as well, causing water to build up and overflow.
-Blocked or Rusted Drain Line Hole
Your unit has a drain hole for the removed water, and it can get clogged up. You should examine the tube to make sure dirt or debris did not get in and block it, if there is simply remove it and water should begin exiting again.
If the drain line has been blocked, the water is not able to escape and has only one way to go, back into the home. Things such as dirt, mold, insects, or anything small can cause a blockage. In some situations there is a second drain line, but this can also become blocked.
-A dirty evaporator coil could be the main cause of the issue. This happens when the water moves dirt into the pan, and causes the drain to get clogged up. We advise having the coils cleaned annually as a part of your yearly A/C maintenance.
If the drain pan is becoming rushed it can fall into your floor, causing damage to the home, it is important to replace them.
Note: AC units can have a secondary drain pan for catching water, these have a float switch that will automatically turn your AC unit off to prevent water damages.
– Cold Weather Temperatures Outside
When the weather outside changes, it can affect the AC unit and when it starts to get to cold out, it can cause excess water too. More water means it will overflow and collect, as it is not as hot out it takes longer to dry up. Once the temperature outside goes up, it should dry up.
– The AC Seals are worn
If the AC unit has seals that are not properly fitted , i.e. loose, rotted, rusted,worn, and etc, it can allow to much hot air to enter. When the warm air hits the cold air in the unit, it condenses and creates the excess water to collect under the unit. By resealing the unit, this can be corrected.
– Air Leakage
In the situation of bad or loose seals, the extra warm air entering the unit and condensing with the cold air creates moisture and a pool of water under the unit. Resealing the outdoor unit can correct this and make things close properly; water leakage is not the only bad thing that can occur.
It is important to take care of the seals as it can reduce the efficiency of the unit, meaning you are not getting the temperature indoors that you want, and paying more than needed.
– Air Filters Get Dirty
If dirty, this causes the coil to become to cold and causes it to freeze up. When melting, the excess water falls and the drain pan may not be designed to hold that much water.
If the unit is freezing up, check your filter. If dirty, simply replace with a new filter.
Depending on the season, it’s recommended to change it out every 1-3 months.
