The amount of money you can save on your energy bill by upgrading your attic insulation depends on several factors such as the type of insulation you install, the size of your attic, the climate in your region, and the condition of your home's HVAC system.
However, in general, upgrading your attic insulation can result in significant energy savings. According to the U.S. Department of Energy, homeowners can save up to 15% on their heating and cooling costs by properly insulating their attics. This translates to an average savings of $200-$400 per year on your energy bill.
Additionally, if you live in an area with extreme temperatures, upgrading your attic insulation can lead to even greater energy savings. For example, in some regions, homeowners can save up to 20% on their energy bills by upgrading their attic insulation.
Keep in mind that the actual amount of money you can save on your energy bill will depend on several factors, including the condition of your home's HVAC system, the efficiency of your appliances, and your personal energy usage habits. Nonetheless, upgrading your attic insulation is generally considered a cost-effective way to save on your energy bill and improve your home's energy efficiency.
