Why Is My Air Conditioner Spitting Water?

Water damage is one of the most potentially harmful and frustrating problems you can experience in your Texas home. But while we might expect to deal with a leak from a plumbing appliance or a bad storm, most homeowners don’t expect it from the air conditioner! Is your cooling system spitting, dripping, or spouting water?

Don’t worry! The AC repair team at Total Air & Heat is here, and we’ve seen this all before. Follow along to learn the common causes of a water leak from your central AC or heat pump.

Your Air Conditioner Is Actually Always Dealing with Water

While a cooling system doesn’t generate water exactly, it does siphon moisture from the air in your home as part of the refrigeration process. In order to cool your home an air conditioner has to first dehumidify the air, which it does by collecting moisture on the condenser coils.

Normally this water drips off safely into the condensate drain system and is harmlessly carried off out of the home where it is drained. But if something goes wrong with that system you can deal with a lot of excess water, and it can add up pretty fast, necessitating an AC repair service.

The Most Common Causes AC Units Leak Water

When an air conditioner is producing or leaking excessive water, one of the following is happening:

  • The condensate line is clogged. This is one of the most common causes, and generally one many homeowners can check for on their own. The condensate drain line is in most cases simply a hose that carries moisture that the AC creates out of the home. If this gets clogged by dust or debris, it will make the drain system fill up until, eventually, it will spill out.
  • The drain pan is damaged. If the line is clean and unobstructed, the next thing to check is the drain pan. This is where generated moisture drips from your evaporator system and collects before it is pumped into or flows into the drain line. If the pan is cracked or otherwise damaged, water will simply spill rather than collect.
  • The air filter needs to be changed. A clogged air filter will choke the airflow in your cooling system, which will create a drop in pressure. When the pressure falls too low in an air conditioner it will begin to literally frost over or freeze, and this will eventually trigger an overheat. When the unit shuts down, the frost will melt, creating the water you’re seeing.
  • You have a refrigerant leak. A worse problem to have, but the results are similar to the clogged air filter. If your AC experiences a refrigerant leak it most likely will continue to try to operate, but without effective refrigerant the cycle will not perform correctly, potentially resulting in frost and ice.

A Note on Window-Mounted Units

If you’re using a window-mounted air conditioner then water actually does just sort of spit out of the unit. But, this should only be happening from the back, or the part protruding out of your home. If it is spitting water in then the most common cause is that the window unit is tilting inward too much or that the sling fan has been damaged.
