Why Is My AC’s Drain Pan Full of Water?

Like all complex devices, your air conditioning system is bound to malfunction from time to time. One of the most common HVAC issues homeowners experience is a drain pan that is full of water. Learn more about this issue and the potential causes here.

What Is a Drain Pan?

Your air conditioning system has a drain pan that is used to catch condensation that drips from the evaporator coils. Because of the temperature difference that occurs during the refrigeration cycle, drops of water will accumulate on the evaporator coils. As the condensation drips from the evaporator coils into the drain pan, it will naturally accumulate water. But while it’s not uncommon for the drain pan will have water in it, if the drain pan is full or overflowing, there is likely an underlying issue.

What Cause the Drain Pan to Fill With Water?

A Clogged Drain Line: If water collects in the drain pan but does not drain through the drain hose, then the hose may be clogged. An air conditioning unit should be periodically inspected because moisture can cause mildew to grow and also because the unit should be inspected for safe operation. The water in the drain pan can also attract insects such as roaches. The drain pan should be cleaned on a regular basis, which will help to control health hazards for your family and also help to prevent problems with pests.

A Faulty Drain Hose: A drain hose can become clogged with debris or can become cracked and cause the drain pan to fill with water. If a drain hose is cracked, then the hose should be replaced, which will ensure that the water will drain properly. A cracked hose can leak water along the route of the hose instead of carrying the water to a splash block. Some homeowners prefer to simply replace a drain hose because cleaning the hose can be a cumbersome process.
