What to Do If My Intertherm Air Conditioning Unit Is Leaking Water?

Water Leak

• Determine where in the air conditioner the water is leaking from. If the water is on the ground outside near the air conditioner unit, it may simply be condensation or water from recent weather or the watering of nearby grass or plants. If the water is pooling around the air conditioner in specific areas, however, the water leak should be further investigated.

Condensate Drain

• Find the condensate drain, which is a three-quarter-inch fitting that comes out of the side of the outdoor unit. Look for a drain trap connected to the drain that prevents water from entering the unit. Sometimes this drain trap gets clogged with debris or dirt and overflows, causing a water leak. Clean out the condensate drain trap and remove any visible obstructions or debris that may be causing the problem.

Condenser Coil

• If the condenser coil on the outdoor unit is iced over, the water may melt slightly and puddle underneath the coil, making the air conditioner look as if there is a water leak. Disconnect power to the air conditioner and allow the unit to defrost and the ice to melt. Once the frost on the condenser coil is melted, use a clean cloth to wipe the coil and clear away any grass, leaves or other material that may be clogging up the coil. Restore power and restart the air conditioner.

Drain Hose

• Find the drain hose on the air conditioner and inspect it for clogs. Straighten out the hose and remove any items that may be sitting on top of the hose, obstructing the flow of water and causing a backup in other areas in the air conditioner. This can also lead to a leak. If you can’t see a clog in the hose but suspect there is one, carefully blow into the hose with a can of compressed air and then set the hose down into a bucket or drain to allow the clog to come out. Shake the hose firmly to help dislodge any items that may be inside. You can also try attaching a wet/dry vacuum to the end of the drain hose and turning on the vacuum to pull the obstruction out.
