Safe first steps, before the call. Nothing here needs a tool.
If you smell gas, a carbon monoxide alarm sounds, or anyone feels dizzy or sick: don’t touch any switch or plug, leave and get everyone out, then call 911 or the gas company from outside.
If water is near an outlet or cord, don’t touch them. Switch the furnace off at the thermostat, then at its breaker. Don’t stand in water to reach the breaker panel; if the panel is wet or you’d have to stand in water, leave it and call.

Everything else about this problem
Is it an emergency?
Is a KitchenAid furnace leaking water an emergency?
Usually urgent, and it can be an emergency. Turn off the water to it and switch off its breaker, then soak up standing water. If water is reaching outlets or cords, switch off the breaker before touching anything; water coming through a ceiling is an emergency.
Symptoms & causes
Water pooling around your KitchenAid furnace, often accompanied by dripping sounds, is a clear indication of a leak. This can manifest as reduced heating performance or even a complete shutdown if safety sensors are triggered by excessive moisture. The root cause typically involves issues with the condensate system, humidifier, or internal components like the heat exchanger.
Tools & parts
You will likely need basic plumbing tools such as a wrench, screwdriver, and a shop vac for cleanup. Replacement parts might include a new condensate pump or sections of PVC pipe for the drain line. If the issue is with an attached humidifier, a new humidifier pan may be needed.
Safety first
Always begin by shutting off both the electrical power to the furnace at the breaker panel and the gas supply valve to prevent electrocution or gas leaks. Be aware that a leaking furnace can create a slip hazard and, if the leak is from the exhaust, could indicate a dangerous carbon monoxide leak. Ensure the area is well-ventilated and consider using a carbon monoxide detector before and during any inspection.
When to call a pro
A professional technician is required if you suspect a cracked heat exchanger, which can lead to dangerous carbon monoxide leaks and requires specialized testing. Similarly, if the leak is from a refrigerant line in a combined furnace/AC unit, handling refrigerants requires EPA certification and specific tools. Any complex electrical issues, such as a short circuit caused by water damage to control boards, should also be addressed by a certified HVAC expert.
Questions people ask
Why is my KitchenAid furnace leaking water only when the AC is on?
This usually indicates a problem with the condensate drain system for your air conditioner, which shares components with the furnace. The drain line might be clogged, or the condensate pump could be failing to remove water effectively.
Can a clogged filter cause my KitchenAid furnace to leak water?
While not a direct cause, an extremely dirty air filter can restrict airflow, causing the evaporator coil (if it's a combined unit) to freeze and then leak water as it thaws. Regularly replacing your filter prevents this secondary issue.
Is it safe to run my KitchenAid furnace if it's leaking water?
No, it is generally not safe to run a leaking furnace, especially if the leak's source is unknown. Water can damage electrical components, create a shock hazard, or indicate a serious issue like a cracked heat exchanger.
