Energy-Efficient Windows: What to Know Before Winter
Chicago winters bring snow, wind, and high heating bills. If your home feels drafty, outdated windows may be the cause. Energy-efficient windows keep your home warm, lower utility costs, and improve comfort.
Why Efficiency Matters in Chicago
Old windows let heat escape and cold air in. Efficient windows keep your HVAC from working overtime, saving you 15–25% on energy bills each year while boosting resale value.
