While this sounds like a serious problem with your furnace, most of the time it’s an indication of a clogged drain.
Though usually not an expensive repair item, it still needs to be attended to.

- Shortening the lifespan of your HVAC system
Air conditioning units and condensation
Air conditioning units normally produce condensation as part of their operating process.
Most of the time, depending where your unit is located, a small drain pipe takes the water to a floor drain.
If the drain or a drain pipe becomes clogged then you will see water showing up where it shouldn’t be.
It’s surprising how often that happens to be under the furnace!
It could be the evaporator coil
Your heating and cooling system can’t function properly without an evaporator coil; a series of piping which sits atop your furnace.
Here’s how it works:
- The furnace blower motor circulates household air through the evaporator coil
- The coil take the air’s heat, cools it down, and sends it back through your home as cool air (done through your air ducts)
- The evaporator coil also dehumidifies the air (turning it into water)
- Water moisture drips into a pan above the furnace and blower motor
The excess water goes down a drain (mentioned earlier in this blog) leading to the floor.
When that drain gets plugged or clogged, water can overflow back to the burners, blower fan motor or evaporator coil.
Here are 6 quick steps you can take
If you notice water leaking from your furnace while the air conditioner is running, here are some fast steps you can take:
1. Turn off the system: Look for the turn-off switch. If you can’t find it, you can always shut it down from your fuse box.
2. Clean up the water: Do this ASAP. Standing water can damage whatever it comes into contact with.
3. Inspect the filter: Confirm your filter is still clean.
4. Use a water-safe vacuum: Suck up any gunk or clog-causing items.
5. Turn on the AC: After you’ve vacuumed, run the AC. If no leaks appear, you’re in good shape.
6. Pour water into the condensation pump: ONLY DO THIS IF THERE APPEARS TO BE NO LEAKS. If the pump doesn’t do anything, that’s a sign of mechanical failure. If it does pump water, the line leading from the pump to the drain is clear.
