Dial In the Right Humidity Level
Don’t over-humidify. The goal is balanced comfort—too much humidity can create condensation and mold risk. The EPA recommends keeping indoor humidity between 30% and 50%. In winter, many homes do best closer to the 30–40% range depending on outdoor temperatures and window/insulation quality.
We can set up a humidistat and show you how to monitor your home’s humidity so you stay comfortable without creating moisture problems.
