The hot, muggy days of summer cause structural damage, warping, mold growth and all kinds of problems. No one seems to mind “dry heat,” but everyone dislikes high humidity. In Illinois, the level of moisture in the air can be extreme. We also experience months of frigid days with low humidity. Here are a few ways that seasonal weather plays a role in your daily life.

Spring and Fall

Weather in the spring and fall is variable. Some days are damp while others are clear and dry. In general, the level of moisture is highest in the morning before convection starts to burn off some of the excess humidity. In the spring, the temperature begins to rise. In the fall, the temperature and humidity steadily decreases. Between the comfortable temperatures and occasional use of your HVAC, your indoor humidity should be ideal at this time of year.

Summer Humidity

The summer heat amplifies the effects of high humidity. When the level of moisture is very high, the temperature feels warmer than it really is. Inside your home, additional water vapor comes from cooking and cleaning. Your HVAC system removes most of this moisture when it cools the air. Make sure that water is draining out of the pan and outlet pipe. Excessive moisture can damage your home and contribute to mold growth.

Dry Winter Air

In the winter, the humidity drops along with the temperature. Cold air doesn’t hold much moisture. Low humidity causes dry skin, chapped lips and nosebleeds. In Northbrook, Illinois, we have many cold days. Although moisture is unpleasant in the summer, it’s beneficial in the winter because it makes the air feel a little bit warmer. By keeping indoor humidity at an ideal level, you can avoid dust mites and reduce the mobility of flu viruses.

Normally, a properly functioning HVAC system should control the moisture in your home. If you’re having problems, check out our range of indoor air quality products online, or call Roberts Heating & Air Conditioning at 847-272-5836.
