Humidity levels can have a huge impact on your comfort and your belongings. When your home's air is over humidified or under humidified, you can face a host of problems. The relative humidity inside the average home during winter is a bone-dry 15%. That's less than the average humidity in the Sahara Desert, which is 25%! Because more humidity makes you feel warmer, it's important to boost humidity levels in the home during winter and reduce humidity during summer. By having Air Group add a whole-house humidifier to your home comfort system, you not only resolve your dry air problems, but you can also save money! Adding humidity in winter means you can often turn down thermostats and still feel warm.
