One of the best ways to dehumidify your home is to keep the AC running at all times. Yeah we know, it doesn’t sound cost effective. But when you’re not running it, it’s not doing its job of dehumidifying your home. Yes, duh. Thank you Captain Obvious! So let’s say it’s raining outside and your AC is set on Auto. It will shut off once the rain has cooled the house down, but if it’s muggy outside, it will eventually get that way inside too. And while the temperature inside might be fine, it’s still going to get muggy due to the excess moisture in the air. Keeping your AC running all day during muggy weather might not sound like the ideal solution when it comes to energy efficiency, but it helps.”

Most professionals would disagree.

If the fan is set to AUTO, that moisture collects and sits on the refrigerant coils. And once the fan shuts off in between cooling cycles, that moisture has time to slide off the coils and drain away outdoors.

But if the fan is set to ON, the moisture on the refrigerant coils does not get the chance to drain away. Because the fan blows constantly, most of the moistures evaporates and gets blown right back into your house!
