What to Do When Your Furnace Is Leaking Water
A furnace leaking water is concerning, but not always an emergency. This guide helps you identify the source of the leak and determine when to call for service in Greater Vancouver.
Immediate Steps to Take
1. Turn off the furnace at the thermostat and at the circuit breaker to prevent electrical hazards. 2. Identify the water source — check for a leaking humidifier mounted on the furnace, a clogged condensate drain on high-efficiency furnaces, or a leaking pipe near the furnace. 3. If the leak is from the condensate drain, clear the blockage using a wet/dry vacuum or by manually removing the clog from the drain line. 4. If the leak is from the humidifier, check the water supply line and the float valve — a stuck float causes overflow.
Next Steps
5. Place towels or a bucket to contain the water and protect your floor from water damage. 6. Check the furnace filter — a water-damaged filter should be replaced immediately. 7. If the leak is from the furnace heat exchanger or internal components, call for professional service immediately — do not operate the furnace. 8. Document the leak with photos before calling — this helps the technician diagnose faster and provides evidence for insurance claims if needed.
