Air Handler In Attic Dripping Water

Sometimes when systems are installed in these areas problems with the condensate drain can cause water to overflow from the drip pan and into the air ducts or air vents.

When that happens the evaporator coil gets too cold and freezes over. The drain pipe is clogged. The secondary drain pan safety switch cuts off the air conditioner if the water level gets too high in the secondary drain pan so it does not cause water damage to your home. There are several components to the air conditioning system that may be contributing to the fact that your condensate line is clogged.

Water is forming in the indoor central ac unit one of the jobs an air conditioner does is pull the humidity out of the air. From this pan the water is sent outdoors through a pipe. Check your air filter to see if it s dirty and change it if needed. As air passes over the evaporator coils in your air conditioner it cools down and loses some of its humidity.

This humidity is left behind in the form of condensation on the coils. A dirty air filter blocks airflow over the evaporator coil. Also it is possible for dirt or debris to become lodged inside. When there is water buildup in your air handler drip pan the first place to look is to a clogged condensate line.

A clogged condensate drain line can occur for a few reasons but especially if your air conditioning system is installed in the attic or on an upper level in your home. When it melts it drips an excess amount of water that the pan may not be able to handle. If the drain pipe is blocked it could cause water to leak from your ac. The collected water then drips down the fins and into a lower collection pan.

As the air passes over the colder metal moisture in the air will condense on the cooling fins. If water is dripping from your ceiling and your furnace and or air handler is located in the attic the most likely cause is a clogged condensate drain line. It is code in many states to have a secondary drain pan and secondary drain pan safety switch installed on all attic air handlers and furnaces. Water is produced as a byproduct of the cooling system and typically drains away from the house through a hose or pipe.

Central air conditioners dispose of hot air and condensation outside the home. An air handler that is leaking water on the floor may be the result of a few issues. A clogged drain pipe is the most common cause of standing water in the drain pan. The blower inside the unit pulls the hot and humid air in the hot air travels through the return grill then over the cold evaporator coil to cool it down.

Over time algae can grow inside of this drain line causing backups or clogs. A malfunction anywhere in this system can cause an air handler to not dispose of water properly and result in water overflowing onto the floor. Blockage in the drain pipe the water in your air conditioner travels to the drain pan via a complex system of drain pipes.
