Why is Water On the Floor Next to My Heating or Cooling Unit?

No matter the size of the leak, it's important to address the problem to prevent damage to the unit and your home. Here's how to figure out what that pool next to your heating or cooling unit really means and what to do if your furnace is leaking water.

Investigating Your System's Puddle Problem

Does your heating and cooling system seem a bit off? That puddle next to your AC or furnace may be a cry for help.

Potential Issues

  • thermostat is blank
  • water leaking from heating or cooling system

In the heating and cooling process, water droplets form at the evaporator coil and collect in a tube. The tube passes runoff water to the drain pan. The pan is equipped with a safety device called the pan float switch, which comes on when the pan is full. This will turn off your HVAC unit to prevent water from leaking on the floor. If the pan is full, there may be an issue with water coming from a frozen coil or a clog in the drain.

The condensate pump on your HVAC unit is used to pump out the condensate (water) that the unit produces during the heating/cooling process. In order to work properly, the condensate pump must be plugged in. If it is not, the unit won't function properly.
