There are a few different reasons why this may be happening. The good thing is the unit is not the normal cause of this failure. Let’s look at some of the reasons and solutions to this issue.

Summertime is when the unit makes condensation so if your unit is installed in the winter always ask the installing contractor to confirm that the drain has been checked and there are no issues.

The DuctlessAire unit has a 1 piece drain pan design. The drain pan is not manufactured to hold water and should drain immediately.

Here are a few items to check during installation and maintenance to help ensure the unit drains properly:

  1. Make sure the unit is installed level.
  2. Make sure that the drain hole was not cut to high because your drain line must run downhill.
  3. Make sure that the wires, inside the blower unit, have not been removed from the zip tie that holds them together. Removing them may cause the wires to block the path of water and the water will follow the wires not the drain.
  4. Make sure that the drain hose is not kinked, nor does it run uphill.
  5. During the install please be aware that if the drain line is moved to the other side of the unit that the drain plug was installed and that it is tight.
  6. Do not use spray foam to seal the unit nor the drain area as it may get inside and expand causing the water to run out the wrong area.
  7. Always have your unit properly serviced by a licensed HVAC contractor before every season starts. This helps maintain the unit and hopefully corrects any issues before they cause a problem.

Remember water follows the path of least resistance so if there is a blockage to it’s normal route the water is going to flow out in the wrong area.
