The answer to 'air filter leaking water' is that a leaking air filter is typically caused by a clogged or dirty filter, a problem with the HVAC system's condensate drainage, or high humidity levels. This can lead to water accumulating around the filter and potentially causing water damage or mold growth.
Some common symptoms include visible water around the filter, a musty odor, or damp areas near the HVAC unit. Solutions may involve replacing the air filter, checking and clearing the condensate drain, or adjusting the HVAC system's settings to better manage humidity. In some cases, calling a professional HVAC technician may be necessary to diagnose and fix the underlying issue.
