Here's more about what causes a furnace to leak water and eight other common heating issues:

It is necessary to address water leaks immediately to prevent more damage to your furnace. Reaching out to a professional HVAC technician like the crew at All Solutions Heating & Cooling is recommended to diagnose and resolve the issue effectively.
