Why Is There Condensation On My Unit?

AC leaks can be troublesome. They are messy and can potentially cause water damage to your home that leads to serious problems. When water is dripping around your AC unit and you have no idea why, contact a professional AC technician for help. Understanding your AC unit is crucial for you to know the root cause of the leakage and evaluate if the issue is minor or requires professional help.

 

If there’s water found below your air unit, this is most likely a result of your unit’s normal operation and this small puddle of water should dry up on a warm day. But if the water leak persists for more than 24 hours, you’ll need the help of a professional air conditioning contractor.

 

Although thermostat setting and outdoor temperature play a role on how much condensation you can expect to see dripping from your air conditioner. These issues can also cause water leaks in your AC system:

 

Dirty Air Filters

A dirty or partially blocked air filter hinders airflow from the evaporator coil. The air conditioner’s evaporator coil gets cold and freezes over. When it melts, the excess water causes overspill from the drain pan.

 

Clogged Condensate Drain Line

If the drain line gets clogged with dirt, insects or mold, the water has nowhere to go so it backs up and floods the overflow pan. You should examine the tube to make sure dirt or debris did not get in and block it.

 

Corroded Or Damaged Drain Pan

Got an air conditioner that is 10 years older? Depending on the age of your AC unit, the drain pan may already be damaged and rusted, causing excess water to fall right through off your air conditioner.

 

Poorly Installed

This is common with a newer air conditioner unit. An AC system that is installed incorrectly can lead to dripping. An improperly designed condensate trap will stop the condensate from draining, and all of the water will build up in the drain pan causing it to overflow.

 

Cold Temperature Outside

When the outdoor temperature is under 60 degrees, it can affect your AC unit. The coil starts to freeze up causing it to condensate, and it will take longer to dry up when the temperature is colder than normal.

 

Low Refrigerant Temperatures

When the evaporator coil is set to a low level, the evaporator coil will become much colder than normal and it will freeze up. When the coil melts, the drain pan will overflow resulting in leakage.
