Air Handler In Attic Dripping Water

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.

Air handler in attic dripping water.

An air handler that is leaking water on the floor may be the result of a few issues. Also it is possible for dirt or debris to become lodged inside. The drain pipe is clogged. Water is produced as a byproduct of the cooling system and typically drains away from the house through a hose or pipe.

This humidity is left behind in the form of condensation on the coils. When it melts it drips an excess amount of water that the pan may not be able to handle. 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. 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.

The blower fan pulls air from the interior space and passes it across the cooling evaporative coil. 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. However the simplest answer may not always be the only answer. Blockage in the drain pipe the water in your air conditioner travels to the drain pan via a complex system of drain pipes.

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. 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. Central air conditioners dispose of hot air and condensation outside the home. Improper installation if your air conditioner is relatively new and leaks a lot of water it is most likely due to an installation issue.

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. As the air passes over the colder metal moisture in the air will condense on the cooling fins. Over time algae can grow inside of this drain line causing backups or clogs. Check your air filter to see if it s dirty and change it if needed.

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. As air passes over the evaporator coils in your air conditioner it cools down and loses some of its humidity. A dirty air filter blocks airflow over the evaporator coil. There are several components to the air conditioning system that may be contributing to the fact that your condensate line is clogged.

If the drain pipe is blocked it could cause water to leak from your ac. From this pan the water is sent outdoors through a pipe. A clogged drain pipe is the most common cause of standing water in the drain pan.
