Air Handler Leaking Water in West Palm Beach, FL?
If your air handler is leaking water, you may have a clogged condensate drain line, overflowing drain pan, float switch shutdown, frozen evaporator coil, dirty filter, or airflow problem. Water around the indoor AC unit should be handled quickly because it can damage flooring, drywall, ceilings, closets, garages, and nearby electrical components.
Koolray Heating and Air helps homeowners in West Palm Beach, Loxahatchee, Wellington, Royal Palm Beach, Westlake, and nearby Palm Beach County areas diagnose air handler water leaks and fix the cause instead of only drying up the mess.
Why is my air handler leaking water?
An air handler leaks water when condensation cannot drain properly or when more water enters the pan than the drain can handle. In Palm Beach County humidity, AC systems remove a lot of moisture from the air, so clogged drain lines, dirty coils, frozen coils, and drain pan problems can show up fast.
Clogged drain line
Algae, sludge, dirt, and debris can block the condensate drain and force water to back up into the pan.
Frozen coil thawing
Ice on the evaporator coil can melt and create more water than the drain pan or line can handle.
Drain pan or float switch
A full pan, damaged pan, bad float switch, or poor drain pitch can create leaks or system shutdowns.
What to do if your air handler is leaking water
These steps can help reduce damage while you wait for service or decide what to do next.
Turn the AC off
If water is actively leaking, turn cooling off to reduce additional condensation and limit water damage.
Check the drain pan
If the pan is full, the drain line may be clogged or the float switch may have shut the system down.
Look for ice
Ice on the coil or refrigerant line can melt and create water around the air handler.
Call if water returns
If water comes back after cleanup, the system needs proper drain and airflow diagnosis.

An air handler leak can appear as a small puddle, a full pan, a shutdown, or damage near the indoor unit.

What usually causes air handler water leaks?
The repair depends on whether the water is caused by drainage, freezing, pan damage, airflow, or system shutdown problems.
Clogged condensate drain
The most common cause is a clogged drain line. Water backs up into the pan and can overflow or trip a safety switch.
Frozen evaporator coil
Restricted airflow, dirty filters, dirty coils, or low refrigerant can cause ice. When ice melts, it can leak around the air handler.
Drain pan problem
Rust, cracks, poor pitch, or an overflowing pan can allow water to escape instead of draining properly.
Float switch shutdown
A float switch can stop the AC to help prevent water damage, but the cause of the water backup still needs to be fixed.
