Your home presents numerous opportunities for enhancing energy efficiency and lowering your utility bills.

Insulation and Air Sealing

Proper insulation and air sealing are fundamental to energy-efficient homes. They prevent heat loss in the winter and heat gain in the summer, reducing the workload on your heating and cooling systems.

• Attic Insulation: The attic is a primary area for heat loss. Ensure adequate insulation with materials like fiberglass, cellulose, or spray foam.
• Wall Insulation: Older homes may lack sufficient wall insulation. Consider options like blown-in insulation or exterior insulation to improve efficiency.
• Basement and Crawl Space Insulation: Insulating these areas prevents heat loss to the ground and reduces moisture problems.
• Air Sealing: Identify and seal air leaks around windows, doors, electrical outlets, and plumbing penetrations to prevent drafts and energy loss.

Windows and Doors

Windows and doors are significant sources of heat transfer. Upgrading to energy-efficient options can make a noticeable difference.

• Energy-Efficient Windows: Look for windows with features like double or triple glazing, low-emissivity (Low-E) coatings, and gas fills between panes for optimal insulation.
