You might be inviting humidity into your property separate from even knowing it by setting your AC control equipment fan to On instead of Auto.
On plus Auto are the multiple settings for your fan! The difference between ON plus AUTO pretty much boils down to when the fan blows.
In the Auto position, the fan only blows during an AC equipment cooling cycle. In the On position, the fan blows regularly, even when the AC isn’t providing any cooling. This also means that it uses more energy plus costs more overall. To better understand how a fan affects indoor humidity, first you should know what the AC equipment fan does plus where it happens to be located. If you have split AC equipment, you absolutely have a couple of fans in your AC equipment. One fan for your outdoor unit plus 1 fan for your indoor unit. The indoor unit fan sits behind the cooling coils plus is basically responsible for pushing air through the ducts plus into your property. Basically, the On setting is not actually permitting your AC equipment to properly dehumidify your place. Your AC has multiple jobs. It cools your property plus dehumidifies it! When warm air from inside your property is pulled into your indoor equipment, it passes over especially freezing refrigerant coils. Those cooling coils absorb the warmth plus moisture from the air. Then, that freezing dry air is completely pushed back into your home. If the fan is set to Auto, that moisture builds up plus sits on the refrigerant coils. Once the fan shuts off in between cooling cycles, that moisture has the ability to slide off the coils plus drain away outdoors. But, if the fan is set to On, the moisture on the refrigerant coils does not have time to drain away. Because the fan blows without stopping, most of the moisture evaporates plus gets blown right back into your property.
