August tends to bring the hottest stretch of the year in most regions — and often the highest energy bills, as air conditioners run nearly nonstop. A few adjustments can keep your home comfortable without letting costs climb as fast as the temperature.
Give your AC a mid-season check. A dirty filter makes a system work harder for the same result. Replacing it every 1–3 months during peak season is one of the simplest, cheapest ways to keep cooling costs in check. The Department of Energy notes that a clogged filter can increase energy use by 5–15%.
Use fans to extend your AC’s reach. Ceiling or portable fans let you raise the thermostat a few degrees while feeling just as cool, since moving air makes a room feel cooler than the same still air. Just remember to turn fans off when you leave a room — they cool people, not spaces.
Block heat before it gets in. Closing blinds or curtains on sun-facing windows during peak afternoon hours can meaningfully reduce indoor heat gain, especially on west-facing rooms that catch the harshest late-day sun.
Time your heat-generating tasks. Ovens, dryers, and dishwashers all add heat and humidity indoors. Running them in the early morning or evening instead of midday keeps your AC from fighting an uphill battle.
Consider a programmable or smart thermostat. Letting the temperature rise slightly while you’re away and cool back down before you’re home can meaningfully cut energy use without sacrificing comfort when it matters.
Check for drafts and gaps. Weatherstripping around doors and windows keeps cool air in just as effectively in summer as it keeps warm air in during winter — an often-overlooked detail worth a quick check.
If you’re weighing bigger energy-efficiency upgrades — new windows, added insulation, or a system replacement — before your next move, a Realty Executives professional can offer perspective on which upgrades tend to matter most to buyers in your market.
