If you are a home building contractor, you already know everything you need to about ventilating a home to keep it insulated and safe. Yet, many homeowners want to ensure their homes are adequately ventilated without paying hefty consulting and contracting fees each time they have a question or make a repair. That is why it helps to understand something about your home's ventilation system and learn how to handle some of the minor adjustments yourself.



Every home needs to be adequately heated to protect family members from getting sick or developing hypothermia. But too much heat can feel uncomfortable during the warm season or in tropical climates and promote the growth of mold or other bacterial invasions that require a warm, moist environment to grow and thrive. A home's thermostat that is linked to the heating and cooling system provides much of the temperature control a family needs to be comfortable year-round. But attic space permitting air flow can increase your home's comfort level by preventing moisture buildup and promoting air exchange during temperature extremes outdoors.

An attic ventilator usually provides this needed service. Since the attic is separate from the sealed part of the house that receives warm and cold air from the furnace and air conditioner, it is the ideal place to circulate indoor air outside, and outdoor air inside, to break up air pockets that can nurture mold, bacteria, and other unwanted germs. If your attic ventilator, which is usually perched on the highest point of the attic, proves inadequate, you may want to consider adding soffit vents beneath the eaves and used with a continuous ridge vent for maximum airflow.

If you are not sure how to tackle the problem of installing soffit vents, ask someone whose home maintenance work you trust for advice or help. Alternatively, you can pick up a handyman's manual or a ventilation guide to learn how to do this procedure yourself. Check out part prices at local hardware stores for an idea of how to budget your ventilation adjustment. Also be sure you have all the needed tools beforehand, along with a few spare parts, if needed.

Venting your home appropriately can reduce the level of toxic emissions or fumes. It also may keep everyone from getting sick as often or passing around the current flu bug, since air that is circulating can make it difficult for germs to grow. Check out your attic to make sure there is good cross ventilation and that your current ventilation system is working properly. Then decide whether this would be a good time to consider adding soffit vents for increased airflow. Try to get it done in good weather so you won't have to work outdoors or in a chilly attic when it's rainy or cold outside.
