Air Conditioner Leaking Water?

It is time for fun in the sun. Unfortunately, with warmer temperatures also comes leaking air conditioners. One of the most frequently asked questions during the summer is “Why is my air conditioner leaking water?” There are multiple reasons as to why this happens but before getting into the causes, turn your air conditioner off to prevent any further damage. Now, it’s important that you understand how water is able to form on your AC unit.

Evaporator Coils

Air conditioning units contain an evaporator coil that cools down the hot air. In turn, this makes condensation form on the coil. The moisture that forms then falls into a drain pan, which then goes down a condensate line.

The Drain Pan is Damaged or Rusted

Some homeowners have air conditioners that are old. If this is the case, your drain pan may not be working properly. If the drain pan is damaged or rusted, the water will run straight through it. You can repair this by simply replacing the drain pan.

The Condensate Pump is Broken

Is your HVAC unit installed in your basement? If so, then there’s a condensate pump that directs the water outside of the house. However, if this pump breaks, the water can't make its way outside. Instead, it’ll either leak or back up. If this is the case, you’ll need to replace or repair the pump.

The Condensation Line is Backed Up

Having a clogged condensate line is actually the most common cause of HVAC leaking water. Over time, the condensation line can become clogged from dust, mold, sludge and dirt. Once this happens, the water that goes through it can back up into your house. To avoid a potentially enormous repair bill, you’ll have to unclog the pipe. There are various methods you can use to unclog the condensation line, such as using a wet/dry vacuum.
However, the best way to unclog your condensate line is to get in touch with an HVAC professional.

Dirty Air Filters

The air filter inside your unit works hard. Over time, it can become clogged with dirt, dust and other contaminants. Once that happens, the airflow that goes over the evaporator coil can become blocked. In turn, the coil itself will end up becoming too cold and eventually freeze over. After melting, it will start dripping too much water and the drain pan will overflow. To prevent this, it's important to change your air filter on a regular basis. In fact, it’s recommended by many HVAC professionals that you change it at least every three months.
