We've addressed the issue of too little moisture in a home, but what if your problem is the opposite and you're fighting excess moisture at every turn. Here, a whole home dehumidifier is your answer. Installed as part of your home's heating and cooling system, a central dehumidifier works in conjunction with your air conditioner to pull air from every room in your home through the return ducts. It then removes the moisture and sends dry air back while balancing humidity levels in your home. On cooler days, when use of the air-conditioner is not needed, the system can also run independently.
