JJ Heating & Cooling Company encourages homeowners to consider a whole-house humidifier and whole-house dehumidifier in Gambrills and Annapolis, MD. The optimal relative humidity (RH) varies from household to household but is somewhere between 30% and 60%. In the Maryland climate, maintaining those levels can be difficult through heating and cooling alone. A dehumidifier helps you keep the RH at 60% or less in summer. A humidifier helps you keep it at 30% or higher in winter.
