The Environmental Protection Agency warns against relative humidity above 60% in summer and below 30% in winter. Many health professionals recommend between 40% and 50% for health reasons and maximum comfort. It’s often not possible to achieve that range through cooling and heating alone. DNA Heating & Air recommends installing a whole-house dehumidifier and whole-house humidifier in Columbus, GA. These systems will let you set RH precisely and maintain it throughout the entire home.
