9 steps to keep your home cool when the temperature tops 100

As the temperatures continue to rise, summer’s heat can be a lot to handle. By taking a few proactive measures, you can create a cooler and more comfortable living environment in your home, while also conserving energy.

Here are nine ways to beat the heat and prepare your home this summer.

Insulate and seal

Start by insulating your home properly to minimize heat transfer. Add insulation to your attic, walls, and crawl spaces to prevent the sun's heat from penetrating your living spaces. Additionally, seal any air leaks around windows, doors, and electrical outlets to prevent warm air from entering and cool air from escaping.

Install reflective window film or shades

Windows are major contributors to heat gain in your home. To combat this, consider installing reflective window film or shades. These additions will help block the sun's rays, reduce heat transfer, and maintain a cooler indoor temperature.

Enhance ventilation

Promoting proper airflow within your home is crucial during extreme heat. Ensure that your ventilation systems, such as fans and air conditioning, are in good working condition. Clean or replace air filters regularly to maintain their efficiency. Additionally, use ceiling fans or portable fans strategically to circulate cool air throughout the rooms.

Create shade

Use exterior shading techniques to reduce direct sunlight exposure. Planting trees strategically around your property can provide shade, block sunlight, and decrease heat absorption. Consider installing retractable awnings, pergolas, or outdoor shades to shield your windows and outdoor living spaces from intense sunlight.

Optimize air conditioning

Make sure your air conditioning system is ready for the heat. Clean or replace air filters, check refrigerant levels, and ensure that the unit is functioning optimally. Consider installing a programmable thermostat to regulate the temperature and energy usage efficiently. Set the thermostat a few degrees higher during times when you're not at home to conserve energy.

Create a cool roof

Your home’s roof absorbs a significant amount of heat, which then radiates into your living spaces. Opt for a cool roof or apply reflective coating to your existing roof to minimize heat absorption. This is especially important for tin or metal roofs. Light-colored or reflective roofing materials can reflect sunlight and reduce the amount of heat transmitted into your home.

Create cool zones in your home

Create cool zones in your home, such as a basement or a designated room with blinds and dark curtains, where you can retreat from the heat and relax. Every home has a “coolish spot” that may be more insulated than others, make this space your own and prioritize staying hydrated and rested.

Fan direction matters

Home ceiling fans are designed to function in both hot and cold extremes. Make sure your ceiling fans are working for you and not against you.

Energy conservation

Extreme heat often leads to a surge in energy consumption. To conserve energy take small steps such as turning off unnecessary lights and appliances, and using energy-efficient LED bulbs, and appliances. Do your best to use appliances during off-peak hours when the energy demand is lower (early in the morning or later in the evening).

Preparing your home for extreme heat can start with a few simple steps. Remember, planning ahead and taking action early in the day will help you beat the heat. Stay safe, stay cool.
