Should in-line humidifier work in AC mode?

Question

Situation: Forced air central heating furnace, AC unit added later, using same fan and ducts.
There is a humidifier unit ("Airking", rotating foam drum) in the return-air duct, and it also operates when the system is in AC mode.
Is that correct? Shouldn't it be disableds in AC mode and only work in Heat mode?

I would find it contradicting if the AC takes humidity out of the air, and the humidifier puts it all back in...

Answer 1

You use the humidifier in the winter to ADD water to the house to compensate for excessive dryness.

You remove moisture in summer to make the humidity bearable.

Running the humidifier in the summer only adds water to the air and you want to remove it.

Some humidifiers may be configured to run only in winter without manual intervention but many require manual processing. Yours appears to need manual intervention.

Shut off the water feed to the humidifier and the power to it during the summer; turn it back on each winter. Note what you did so you can do it easily.

Best of luck

Answer 2

Assuming the humidifier is operated by a controler:

The set point for the humidifier should be set very low (10/20/30%) to avoid it trying to humidify conditioned air.

You might just turn it off by unpluging, disconnecting, turning off the water supply.

Assuming the humidifier is not operated by a controler:

Turn it off! You could possibly just turn the water supply to it off.

I live in Florida. There's not a humidifier within 500 miles!
