You already know that inadequate ventilation in the home can lead to mold, mildew, and poor indoor airflow.This, in turn, can trap pollutants indoors, leading to allergies and other, more serious health risks. So what can you do to prevent this? Fortunately, you have several options, including energy efficient ones. Here are some of them. Install a Ceiling Fan Ceiling fans help circulate the air around your home. They reduce your cooling bill by drawing cool air upwards on warm days. In the winter, ceiling fans are also efficient, reducing your heating bill. For instance, if you use a fireplace, using a ceiling fan can make it more efficient by distributing the heated air. Install a Heat Recovery Ventilator (HRV) Heat recovery ventilators circulate fresh air into your home. They also recover heat from exhaust air as it exits the building, saving 60 to 80 percent of heat that is usually wasted. By recycling this heat, the burden on heating and cooling systems is largely reduced. HRVs can be retrofit into new or existing homes. Install Proper Attic Ventilation Having good air flow in the attic also reduces energy costs by preventing heat from being trapped in high areas. Possibilities for ventilating here include installing gable end vents, installing an attic fan, or including ridge venting in your new roof design. Keep Appliances Ventilated and Efficient Air should flow through the room, as well as to and from appliances. Maintaining appliance vents will help keep them running efficiently and prevent dust from blocking air flow. Remember to unclog and regularly upgrade your dryer vent, keep refrigerator vents unblocked, and generally keep your filters clean.
