Leaking humidifier, humidifier pad had not been replaced in quite some time. This caused humidifier hose to become clogged with debris and not work properly. Also humidifier was set to wrong setting of "summer" during winter season. Replaced filter, recommended a newer more efficient humidifier to save cost on electrical bills, and cleaned out humidifier line. Humidifier operating properly at this time. Informed customer on settings and how to replace future filters if they decide to stay with this model.
