The answer is that running a gas furnace can lead to lower humidity inside a house. The furnace's burners don't dry out the air, however.

Will turning on heat lower humidity in house?

Contrary to popular belief, heating the air actually lowers the relative humidity. This is because, as the temperature of the air increases, the air can hold more molecules, and its relative humidity goes down. The warmer the air, the greater its capacity to hold water.

Does forced air heating reduce humidity?

And it doesn't help when you run your heater, right? Forced-air heating systems like furnaces, heat pumps, or even space heaters seem to suck out moisture even more. What's happening is that the colder the temperatures are, the harder it is to “hold on” to humidity.

What temperature removes humidity?

If the air temperature decreases below 70°F, the air cannot hold more moisture and the moisture starts to be removed from the air.

Does heat raise or lower humidity?

Warm air can possess more water vapor (moisture) than cold air, so with the same amount of absolute/specific humidity, air will have a HIGHER relative humidity if the air is cooler, and a LOWER relative humidity if the air is warmer.

Does running furnace fan reduce humidity in summer?
