Water leaking from a furnace typically occurs due to condensation. The furnace's exhaust system contains a condensate line that collects moisture and runs it away from the unit, either outside or into a nearby drainpipe. If this line becomes blocked, water will build up in the exhaust system and eventually start leaking from the unit. Additionally, if the evaporator coil of your furnace is dirty, it can cause excessive condensation and lead to leaking water.
In order to determine why your furnace is leaking water, you'll need to inspect all of its components for any signs of blockage or dirt accumulation. Start by examining the condensate line for any clogs or breaks in the pipe. If there are none, then check the evaporator coil to see if it has any dirt or debris buildup. Cleaning the evaporator coil can often fix this issue and stop your furnace from leaking water. If not, then you may need to replace the condensate line or call a professional HVAC technician for assistance.
No matter why your furnace is leaking water, it's important to address the problem right away in order to prevent further damage to your home and its components. Taking care of any necessary repairs or replacements will help ensure that your unit continues running without incident for many years to come.
