The blower wheel is the component that pulls large amounts of air from the outdoors into your system.
Central ac unit leaking water outside.
The loud water leaking out is normal when you live in a high humidity area or if the humidity is abnormally high.
An air handler that is leaking water on the floor may be the result of a few issues.
Unclog the condensate line.
Central air conditioners dispose of hot air and condensation outside the home.
When the water forms around the evaporator coil in goes into a sloped drain and goes down the condensate drain line.
That drain line usually a pvc pipe either exits out the home usually near the outside unit or into your plumbing.
A dirty blower wheel.
From time to time you may notice your air conditioner leaking water outside.
And if your unit has a leaking refrigerant it may either still be fixed or you already need to get a new window or central air conditioner.
The central ac unit is doing it s job and removing the extra humidity in your home therefore you may hear or see more water coming from the condensation tube.
Because it s located outside your house near your condenser the line.
In this situation just like ice water on a hot day the evaporator coil creates condensation.
The most common gremlin behind a central air conditioner s leakages is a clogged condensate line.
Water is produced as a byproduct of the cooling system and typically drains away from the house through a hose or pipe.
Walking outdoors to find a puddle of water underneath your ac s condenser unit might be alarming but it s important to understand when an air conditioner leaking water is normal and when it may indicate an issue with your unit that requires air conditioner repair services.
Refrigerant is low if the refrigerant of your ac is running low this will also cause your unit s coils to freeze resulting in water overflowing the pan when it melts.
Ok so now you have a general idea of how the water forms and the parts involved.
