When you consider the "Home as a System", each system within needs to work together to provide comfort and protection to occupants. "Air Sealing" is most important for comfort and energy savings. If you have a highly insulated house that is leaky, you will lose heat and energy. Free testing is available from various companies to see exactly how leaky your home is. After sealing for leakage, insulation is the next best improvement. It will increase your comfort by increasing the time it takes "conditioned air" (heated or cooled) from escaping via conduction, and radiance, you did attic air sealing! Darker roofed houses can avoid solar heat gain by installing radiant barriers, full or partial! Second floor hard to heat/cool? I can help! Properly sealed ducts deliver heat where you want it. It doesn't cost much to improve your comfort! Saving lasts forever. The saving start's here! #330 225 2965
