Leaking water from an air conditioner can be confusing. The dehumidifying process of the air conditioner often causes some condensation, but pooling or leaking water is different. There are a few things that can cause such a leak and most of them need to be addressed in order for your unit to run more efficiently.
The EPA site can help you determine what might be causing problems for your air conditioner. There are also great suggestions on how to make your home more energy efficient.
If you look at your unit and run a few tests, you might be able to find the source of the leak. Sometimes it is necessary to consult a professional to correct the problem, while other times you can fix it yourself.
1.Pump is Broken
First and foremost, your condenser pump may be broken. You can test this by pouring water in the condenser pan to see if it can properly pump out the excess. If it cannot, first check the power to the pump. If the power is good, then it is likely the motor or the condenser itself. You should consult a professional to determine what the specific source of the problem is.
When air conditioning units are improperly installed they can leak water. If the unit is not level or if there is too much pressure, water may begin to pool. Check to see if the unit is level first. If that is not the source of the problem, look for any closed vents in the house. The added pressure can sometimes cause the valves to leak.
3.Drain Hole is Blocked
There is a drain hole for the removed water on your unit. Sometimes this can get blocked with dirt or other debris. Check the tubing to see if this is the case. Clear the blockage if there is one, as it will allow the water to properly exit the condenser pan and you should see the pooling stop.
4.Outside Temperature is Too Cold
When the temperature starts to change you can actually end up with extra water build-up due to the outside temperature being too cold. It causes more water to build around the unit and then you get the pooling, as it doesn’t evaporate as it normally does. If it is just a small amount of water, you may not need to do anything. When it gets hot again the pooling will stop.
If your seals on the air conditioner are not tight, excess warm air can get inside the unit. This causes the moisture from the air to condense when it meets the cold air inside the air conditioner. The excess moisture then pools below the unit. In this case you need to reseal the outside of the unit and make sure everything is properly closed.
Pooling water is not the worst thing that can happen to an AC unit, but you do want to take care of it. If water is pooling, your air conditioner is not running as efficiently as it could. This means you are spending more money and your home is likely not the temperature you want it to be. If you don’t want to figure out why it is pooling, call a professional, it is often an easy fix.
