Tips for Weatherizing Your Home
A typical home can lose 20% of its conditioned air to leaky ducts. To improve performance, we suggest sealing ducts with mastic sealant. Remember, the traditional duct tape people have lying in their closet or toolbox should not be used because the heated air degrades it quickly. When sealing ductwork, keep the following in mind:
Your house has pipes and ducts that run through floors and ceilings, and most of these conduits have unintentional gaps around them. The gaps likely allow too much conditioned air to escape through the floor, attic and crawlspace, wasting both energy and money.
Remember, it’s possible to over-seal your home, resulting in inadequate air circulation between the indoor and outdoor environments. This can pose a health and safety risk. Goals2Green uses a blower door diagnostic test to quantify air circulation, which allows us to recommend the appropriate amount of ventilation for your home.
