</html><description>Ventilating Your Home by the Barrie Home Inspector. In energy efficient homes there can be a shortage of fresh air entering the home which can cause what was termed the "sick building syndrome". This is basically when there is more air leaving the home through various sources, such as; fireplaces, furnaces, exhaust fans, hot water tanks and wood stoves. Some of the common symptoms were; back drafting of combustion appliances, mold, mildew and condensation on walls, lack of fresh air with musty and stale odors and a noticeable rush of air into the house when opening a door or window.</description></oembed>
