Understanding Heat and How It Affects Your Home

To effectively keep your house cool, it’s essential to understand how heat enters and moves through your home. Heat enters your house in three main ways: conduction, convection, and radiation.

Conduction: This is the process where heat is transferred through solid materials. For example, the walls, roof, and windows of your home can conduct heat from the outside into your living spaces.

Convection: This refers to the transfer of heat through the air. Warm air from outside can enter your home through gaps, cracks, and ventilation systems, raising the indoor temperature.

Radiation: Heat can also enter your home through radiation, primarily from the sun. Sunlight passes through windows and heats up surfaces inside your house.

Understanding these processes helps you target specific areas of your home for cooling improvements.

Quick Fixes and Simple Strategies

Close Blinds and Curtains: One of the simplest ways to keep your house cool is by blocking out sunlight. Use blackout curtains or blinds to prevent heat from entering through windows. Reflective shades or window films can also reduce heat gain.

Use Fans Effectively: Ceiling fans, box fans, and oscillating fans can help circulate air and create a cooling breeze. In the evening, place a fan near an open window to draw in cooler air from outside.

Optimize Your Thermostat: Set your thermostat to a higher temperature when youโ€™re not home to save energy, and lower it when you return. Programmable thermostats can help automate this process.

Cook Outdoors: Using your oven or stove can significantly increase the temperature inside your home. Opt for grilling outside, using a microwave, or preparing cold meals to keep indoor heat to a minimum.

Seal Gaps and Cracks: Prevent warm air from entering your home by sealing gaps and cracks around windows, doors, and vents with weatherstripping or caulk.

Use Light-Colored Textiles: Light-colored sheets, curtains, and furniture covers can reflect rather than absorb heat, helping to keep rooms cooler.

Hydrate and Dress Appropriately: Keep yourself cool by staying hydrated and wearing lightweight, breathable clothing. Personal comfort can reduce the temptation to crank up the air conditioning.
