Home ventilation is extremely important to help improve air quality and circulation. This section provides informative articles about house ventilation, ENERGY STAR mechanical ventilation, attic ventilation, basement ventilation, bathroom ventilation, ENGERY STAR duct systems, and radon ventilation.

  • Ventilation

    Consider: House Ventilation, Energy Star Mechanical Ventilation, Attic Ventilation, Basement Ventilation, Bathroom Ventilation, Duct Work, Cleaning Duct Work Specifications, Energy Star Duct Systems, Dryer Ventilation, Radon Ventilation, and Natural Ventilation.

    For centuries if not millennia, natural ventilation used to be the most common ventilation method of allowing fresh outdoor air to replace indoor air in a home. Today it is just one of the many options, since homes that are properly air sealed for energy efficiency benefit from mechanical ventilation.
  • How to Create an Efficient Duct System

    To create a comfortable home, an efficient duct system is a must. Ducts—known collectively as the air distribution system—carry air from the central heater or air conditioner to each part of the home and back again. Up to 50 percent of the energy used to heat or cool air can be wasted if ducts are not sealed and insulated properly. That’s why the duct systems found in ENERGY STAR qualified homes are third-party tested for tightness and verified to be properly insulated.

  • How Home Ventilation Systems Work

    A variety of mechanical ventilation systems are available to select from, based on local climate and the home’s heating and cooling system. In addition to one of the primary ventilation systems described below, “spot” ventilation fans should also be provided for ventilating kitchens and baths to remove the concentrated moisture and odors that can occur in these rooms. Here is a description of the typical ventilation systems and recommended climates:

  • Benefits of Mechanical Ventilation

    Moisture, odors, and other pollutants can build up inside a home if it does not have mechanical ventilation to provide fresh air. Mechanical ventilation systems circulate fresh air using ducts and fans rather than relying on airflow through small holes or cracks in a home’s construction assemblies (e.g., walls, roofs, or windows). Homeowners can breathe easier knowing their home has good ventilation.

    The benefits of proper home ventilation include the following:
