Summer in Iowa can be brutal, and if you’ve ever opened an electric bill in July and done a double take, you’re not alone. Running your air conditioner around the clock keeps your family comfortable, but it doesn’t have to break the bank. The good news is that most homeowners have more control over their cooling costs than they realize. With a few smart habits and simple adjustments, you can stay cool all summer long without dreading your next utility bill. Here’s what makes a difference.
Thermostat habits (biggest impact):
- Set it as high as is comfortable – around 78°F when you’re home. Every degree lower can add roughly 3–5% to cooling costs.
- Use a programmable or smart thermostat to let the house warm up while you’re away or asleep, then cool down before you return. Don’t shut the AC off entirely on hot days, though. Recooling a baked-out house can cost more than maintaining it.
- Run the fan on “auto,” not “on,” so it isn’t circulating air when the system isn’t actively cooling.
Block the heat before it gets in
- Close blinds, curtains, or shades during the day, especially on south- and west-facing windows. Blackout or reflective shades help most.
- Seal air leaks around windows and doors with weatherstripping and caulk so you’re not cooling air that escapes.
- Improve attic insulation if it’s thin. Attics are a major source of heat gain.
Use fans wisely
- Ceiling and box fans let you feel comfortable a few degrees warmer, so you can raise the thermostat. Just remember fans cool people, not rooms. Turn them off when you leave.
- Run bathroom and kitchen exhaust fans briefly to pull out heat and humidity after showers and cooking.
Reduce indoor heat sources
- Run the dishwasher, dryer, and oven in the evening when it’s cooler. Better yet, grill outside, use the microwave, or cook no-heat meals on the hottest days.
- Switch to LED bulbs, which give off far less heat than incandescent.
Keep the system running efficiently
- Replace or clean the air filter every 1–3 months. A clogged filter forces the system to work much harder.
- Keep the outdoor condenser unit clear of grass, leaves, and debris, and give it a couple feet of breathing room. Shading it (without blocking airflow) helps too.
- Get an annual professional tune-up to check refrigerant, clean coils, and catch small problems before they become expensive ones.
- Have leaky ductwork sealed leaks can waste a big chunk of your cooled air before it reaches the rooms.
