How Much Can You Save with Energy Efficient Windows?

California’s climate makes energy-efficient windows a must-have. The U.S. Department of Energy estimates that heat gain and loss through windows accounts for 25-30% of residential energy use. By replacing old single-pane windows with ENERGY STAR-rated models, California homeowners can expect:

• Annual energy savings of $125 to $465 per year

• Reduced cooling costs by 30% in warm climates like Southern California

• Lower heating costs by 20% in cooler Northern California regions

Over a 20-year lifespan, energy-efficient windows can save homeowners $2,500 to $9,000 in utility costs.
