Low-Cost Strategies to Keep Your Home Cool

1. Window Management

Windows are a major entry point for heat. Experts at the U.S. Department of Energy recommend closing blinds or curtains during peak sunny hours, especially on south and west-facing windows. Reflective window films or blackout shades can significantly reduce solar gain. At night, opening windows (where safe) lets cooler air in, creating a cross-breeze that naturally lowers indoor temperatures.

2. Insulation Upgrades

Insulating walls, roofs, and floors prevents outside heat from entering. While major upgrades can be costly, even inexpensive measures like weatherstripping doors and windows, or using door draft-stoppers, provide significant benefits. According to Mayo Clinic, maintaining a consistent indoor temperature is crucial for health and sleep quality.

3. Appliance Awareness

Appliances generate surprising amounts of heat, particularly ovens, stoves, computers, and even televisions. The Centers for Disease Control and Prevention (CDC) endorse minimizing appliance use during the hottest parts of the day. Consider meal-prepping in the early morning or evening, or making no-cook recipes to avoid unnecessarily warming your kitchen. Turn off devices and lights when not in use, and unplug chargers, which contribute to “phantom heat.”
