The answer to 'air handler leaking water' is that the most common causes are a clogged condensate drain line, a faulty condensate pump, or a problem with the air handler's drain pan. This can lead to water leaking from the air handler and potentially causing water damage in your home.
Some key symptoms to look for include water pooling around the air handler, water stains on the ceiling or walls, or a musty odor. To address the issue, you'll first want to check the condensate drain line for any clogs or blockages. If the drain line is clear, the problem may be with the condensate pump or a crack in the drain pan.
