Attic Fan Humidity Control

Humidity settings are another issue that can make or break the performance of your heating and cooling systems and your attic ventilation.

Attic fan humidity control.

Regardless of the type of fan you choose make sure to run it on a fairly consistent basis. Below are some of the most common causes of high humidity in an attic. The moisture was rising with the warm air of the home as it escaped past the insulation and it was trapped in the attic because there was no roof ventilation. During the winter months the recommended relative humidity inside a house is anywhere between 30 50 percent.

During winter months humidity from this escaping air can condense on cold attic surfaces leading to mold. At higher levels relative humidity condensation can even occur inside of the house on windows cold walls or ceiling surfaces. If your attic is particularly large you may want to use more than one electric fan. If you re looking to de moisturize your attic on a budget a standard electric fan should adequately control the humidity of all but the most humid attics.

So the first step is to seal the air leaks.

The normal indoor humidity range in winter should be 15. You need to make sure there is adequate ventilation in your attic to allow warm moist air to escape.
