Your AC is working overtime, but the problem might not be outside. Five common indoor heat sources can add thousands of BTUs to your cooling load, driving up energy bills by 20 to 40%.
Windows are responsible for up to 30% of your home’s heating and cooling loss, making them one of the biggest comfort and energy drains in any season. Thermal curtains are a low-cost, renter-friendly fix that can slash that loss significantly and pay for themselves within months.
South and west-facing windows can turn a comfortable room into an oven by mid-afternoon, driving your AC to work overtime. A simple solar control window film costing as little as $15 blocks up to 79% of solar heat gain and can shave 8 degrees off your room temperature without blocking your view.
Most homeowners leave windows open at the wrong times, accidentally pulling hot air in and trapping heat inside. A simple shift in your window routine, timed around outdoor temperatures, can drop indoor temps by 5 degrees or more without touching your thermostat.
