The answer to 'evaporator coil leaking water' is that a leaking evaporator coil is a common HVAC issue that can be caused by a few different factors. The most common causes are a clogged condensate drain line, a problem with the condensate pump, or simply a worn-out coil that needs replacement.
If the evaporator coil is leaking, you'll likely notice water dripping from the indoor unit and potentially puddles on the floor around the system. This can lead to water damage and mold growth if not addressed. In many cases, the issue can be resolved by clearing a blocked drain line or troubleshooting the condensate pump. However, if the coil itself is damaged or deteriorating, it will need to be professionally replaced.
