  • Emptying the condensate drain pan or pump according to the manufacturer’s instructions.
  • Scheduling professional maintenance checks every few years.

Here are the components of a whole home dehumidifier:

  • Drain pan: The collected condensate is drained away, typically to a floor drain or sump pump.
  • Reheat coil (optional): In some models, a reheat coil can be used to slightly warm the dry air before it’s distributed, preventing your home from feeling too cool.
  • Humidistat: The control panel adjusts the humidity level and switches the dehumidifier.
