How Does Water Form in an Air Conditioner?
The water in an air conditioner forms when warm air passes over the cold evaporator coils.
Common Causes of an Air Conditioner Leaking Water
1.
Dirty Air Filter
One of the easiest problems to fix is a dirty air filter.
The longer the air conditioner is operating, the higher the chance that the evaporator coils will freeze.
During this period, the warmer air thaws the ice, causing it to melt into water.
To fix this problem, simplychange the air filter on a regular basis.
This issue can be resolved by replacing the damaged air conditioner insulation.
Typically, you’re free to purchase insulation online or at a local home improvement store.
Frozen Evaporator Coils
The purpose of evaporator coils is to cool the incoming warm air.
Ideally, the condensation drips down into the drain pan and drains through the condensate drain line.
The longer the air conditioner works, the higher the chance that the evaporator coils will freeze.
When the air conditioner shuts off, the warm air thaws the ice.
The meltwater quickly overflows the drain pan, leading to a leak.
Leaking Drain Pan
When condensation forms, it drops down into the drain pan.
The only option to fix this leak is to replace the drain pan.
As the water continues to collect, it will overflow the drain pan.
The condensate drain line can usually be cleared with a mild solution of water and vinegar.
As a last resort, you might replace the condensate drain line.
Damaged Condenser Unit
The condenser unit is the part of the air conditioner that sits outside the home.
Despite what many people believe, the condenser does not pull air in from outdoors.
It’s recommended to contact an HVAC repair professional to assess the damage and suggest next steps.
