Your most valuable asset is your home. Poor indoor air quality may be slowly destroying that asset.  Conditions that could be affecting the very structural integrity of your home include air that is too dry or too moist, and/or that contains dust or mold.  It goes beyond the aesthetics of darkening spots on wood floors or discoloration of walls; wood can actually warp and deteriorate to the point where it becomes hazardous, drywall can crumble away from the touch. Just replacing the affected material is a temporary fix; it doesn't correct the underlying condition that will again lead to the expense and hassle of replacement. To properly protect and preserve your home, to keep it looking it good and avoid unnecessary repairs and expenses, an effective indoor air quality solution helps ensure the longevity and quality of not only the building materials that you see everyday in your home, but what's going on beneath the surfaces.
