In basic terms, humidity is the level of moisture in the air. When it’s especially low or high, it can make it more difficult for you to breathe comfortably, and it can even lead to the circulation of contaminants like bacteria or mold. While you cannot control the humidity levels outdoors, you can take steps to improve the quality of air inside your home. Here’s what you should know about your home’s humidity and the HVAC upgrades that can improve your indoor air quality.

The Link Between Humidity, HVAC Systems & Indoor Air Quality

How Humidity Impacts Air Quality

hvacLow humidity is when there is hardly any moisture in the air. This normally occurs during winter. These conditions dry out your eyes, nose, mouth, throat, and skin. High humidity, which normally occurs in the summer, leads to heavier air that is more difficult to breathe in. It also can contribute to mold and bacteria growth around your home. Those microscopic organisms circulate through your HVAC system and irritate those with allergies, asthma, or other respiratory issues.

How to Control Your Home’s Humidity

Since there are issues that arise when levels are either too low or too high, your goal should be to maintain moderate humidity in your home throughout the year. In the winter, that normally means running a humidifier to add moisture to the air. In the summer, air conditioning removes moisture. Talk to your HVAC contractor about having these items added to your system, so they can run throughout the entire house.
