The answer to 'furnace leaking water' is that a leaking furnace is a common problem that can have several potential causes, including a clogged condensate drain line, a cracked heat exchanger, or issues with the furnace's humidifier. The symptoms may include water pooling around the furnace, water dripping from the unit, or visible signs of moisture.
In many cases, a leaking furnace can be fixed relatively easily by a homeowner, such as by clearing a blocked condensate drain. However, more serious issues like a cracked heat exchanger may require the expertise of a professional HVAC technician to properly diagnose and repair. It's important to address a leaking furnace promptly to prevent further water damage and ensure the safe operation of the unit.
