It’s no secret — St. Louis summers can be scorching. With recent heat indexes topping 100°F and warnings from the National Weather Service, staying cool isn’t just about comfort — it’s about safety and cost-efficiency, too.

Whether you're preparing your home to sell or just want to lower your energy bill, making smart, heat-beating upgrades is a win-win. Here are some cost-saving home improvements that will help you keep cool and cut utility costs — while also adding value to your property.

🌬️ 1. Seal the Leaks and Insulate Like a Pro

Air leaks around doors, windows, and attic spaces can turn your cool air into dollar signs flying out the window.
Quick fix: Add weatherstripping and caulk around windows and doors.
Long-term upgrade: Insulate your attic and exterior walls. A properly insulated attic can reduce cooling costs by up to 30%.

🪟 2. Install Energy-Efficient Windows (or Add Solar Screens)

Old, single-pane windows are no match for the St. Louis sun.
Upgrade: Consider low-E or double-pane windows to reduce heat transfer.
On a budget? Solar screens or reflective film can block up to 70% of solar heat.

💨 3. Add or Upgrade Ceiling Fans

Ceiling fans use far less energy than air conditioning and help circulate cool air.
Pro tip: Make sure they rotate counterclockwise in the summer to push cool air down.

🌳 4. Strategic Landscaping for Shade

Planting shade trees near windows or installing pergolas and trellises can naturally cool your home and your yard.
Fast option: Add exterior shade sails or roll-down bamboo shades over patios and windows.

❄️ 5. Upgrade to a Smart Thermostat

Smart thermostats learn your schedule and adjust temperatures accordingly — keeping you cool when you need it and saving energy when you don’t.
Bonus: Many utility companies in Missouri offer rebates for smart thermostat installations.

🔄 6. Service or Replace Your HVAC System

An overworked or outdated system can drive up your cooling bill.
Maintain: Have it professionally serviced at the start of summer.
Upgrade: ENERGY STAR–rated units can cut your energy use by 15% or more.

💡 7. Switch to LED Bulbs and Energy-Efficient Appliances

Traditional bulbs and older appliances emit heat, making your A/C work harder.
Easy win: Swap bulbs for LEDs and unplug heat-generating electronics during the hottest hours of the day.
