Whole-house dehumidifier not working? It happens.

Here's when you may need an Atlanta dehumidifier repair service

Your whole-house dehumidifier might be acting up if you experience any of the following problems:

  • Not dehumidifying: The dehumidifier is running, but it isn't removing moisture from the air.
  • Increasing humidity, not decreasing it: This could indicate that your whole-house dehumidifier was not installed as well as it could have been.
  • Won't turn on: Humidity is increasing, but the dehumidifier is unresponsive.
  • Unit shuts off: Your dehumidifier was running, but it shut off all of a sudden. Now it won't start up again.
  • Water overflow or leaks: The water is overflowing from the unit itself or from your condensate pump.
  • Dehumidifier Noise: Your whole-house dehumidifier wasn't audible, but now you can clearly hear or feel it running through your floor (crawlspace installation) or ceiling (attic installation).


The following problems are common among whole-house dehumidifiers. Many can be addressed without replacing the unit:

  • Bad control board (PCB)
  • Clogged drain line that trips the unit's float switch
  • Improper refrigerant charge
  • Refrigerant leaking from the coil
  • Dirty air filter
  • Fan motor issues
  • Bad capacitor
  • Inaccurate humidistat
  • Inadequate installation or ductwork connections
  • Design or installation that creates excessive noise or vibration

Whole-house dehumidifier problems don't always require repair. Sometimes, they need to be reinstalled.

Most HVAC companies install whole-house dehumidifiers using the "return-to-return" method. The dehumidifier brings in air through your return ductwork, removes moisture, and sends the dry air back into the return. Sometimes, this works. But not always.

In many cases, this method forces more humidity into your home, not less.

That's because it's blowing air over your AC's wet evaporator coil. When your dehumidifier can't keep up, we may be able to reinstall the unit using this method.

That way, you can solve your dehumidifier issue without having to repair the unit.

Whole-house dehumidifier problems don't always require repair. Sometimes, they need to be reinstalled.

But when your whole-house dehumidifier won't run at all...

Then it probably will require repair.

Many dehumidifier problems can be resolved by replacing the control board, unclogging the unit's drain line, or recharging the refrigerant. Other issues, such as a refrigerant leak, may be more challenging to resolve.

When our team visits your home to analyze your dehumidifier, we run troubleshoot every conceivable issue to determine the exact source of the problem.
