Looking to cut energy costs and improve home comfort? Focus on your heating and cooling systems. While it is imperative to choose an Energy Star-certified unit properly sized for your home, a variety of factors influence the effectiveness of your system, according to the experts at Lennox. And some of those factors, it turns out, have very little to do with areas of the home that you actually live in.
Your attic is the primary buffer zone between the conditioned air of your home and the roof that shields your dwelling from the elements. If your attic is not properly insulated and ventilated, then your home may be losing heat in the winter and cool air in summer. As a result, your furnace and air conditioning units may be working harder than necessary to maintain a comfortable indoor temperature.
Proper attic insulation is key to ensuring that you pay no more than necessary to run your HVAC equipment. Requirements vary by region, but for most attics, the recommended R-value is up to R-38, or about ten to 14 inches, depending on insulation type.
