How Heating Affects Humidity Levels

We live in a muggy part of the country, there’s no denying it, and here in Houston, TX, heating systems need to deal with the humidity as much as the temperature. Wet air can create a clammy, uncomfortable feeling in the home, as well as encouraging the growth of mold and bacteria. You can include a dehumidifier in your heating system to help reduce the level of humidity, but before making that investment, it’s important to understand how heating affects humidity levels, and by extension, how a dehumidifier can help.

By humidity, we talking about relative humidity, which is the ratio of absolute humidity (the amount of water in the air) to the highest possible humidity given the temperature at the time. 100% relative humidity basically means rain. Most human beings feel comfortable with relative humidity levels at about 35-45%, which is often much lower than Houston’s outdoor relative humidity levels.

How does heating enter into that? Hot air can hold more moisture than cool air, which means a warm house tends to be more humid than a cool one. Conversely, cool air holds less humidity, making it drier the lower the temperature. This is why your home may feel dry on a cold winter’s day. Ironically, heating tends to contribute to that dryness since blown air tends to wick up sweat and moisture from your skin.

In the winter time, you can increase humidity levels by attached a whole-house humidifier to your furnace, or by purchasing a small portable humidifier for individual use. In Houston, we usually have the opposite problem. A whole-house dehumidifier will help keep the air from getting too many, while contributing strongly to your family’s overall health and comfort. In either case, you can find sound advice from the Houston, TX heating system experts at Texas Central Air. We know how heating affects humidity levels, and can make recommendations that fit your household before performing an installation with courtesy and care.
