You walk through your front door and feel it: the air is warm, not just outside but inside too. Minnesota summer has arrived, and with it, a surge in cooling costs. As temperatures push into the high 70s and 80s °F and humidity ticks upward, your home’s energy use can spike—especially if cooling systems aren’t optimized. But with the right approach, you can stay comfortable and keep bills in check.

7 Practical Energy-Saving Tips for Minnesota’s Summer

1. Keep Thermostat at a Smart Temperature

The U.S. Department of Energy and Minnesota Commerce Department recommend setting your thermostat to 78 °F when you’re home and raising it 5–10°F higher when away—typically to 85°F—to avoid overcooling while managing humidity.

2. Use Ceiling Fans Wisely

Set ceiling fans to rotate counter-clockwise to create a cooling breeze. That breeze lets you raise your AC temperature by about 4°F, saving up to 10–12% monthly.

3. Maintain AC Efficiency

Annual servicing, filter changes every 1–3 months, and clearing debris from outdoor units keep AC systems running at peak efficiency, and prevent energy waste.

4. Block Heat from Windows

Up to 30% of indoor heat enters through windows—shades, blinds, or heat-reflective film on east, west, and south-facing windows can significantly reduce this load.

5. Schedule Smart Usage

Cook outside, delay laundry and dishwasher use until evening or early morning when it's cooler—heat-generating appliances force the AC to work harder.

6. Use Night Ventilation

Open windows and run fans to draw in cool overnight air. In the morning, close them before the heat hits to lock in comfort.

7. Seal & Insulate

Weather-strip doors and windows, close blinds during peak sun, and keep unused rooms closed off. These steps reduce cooling loss and focus energy use where it counts 

Beyond Day-to-Day: Long-Term Upgrades

• Smart Thermostats & Rebates: Installing a programmable or smart thermostat can optimize cooling schedules. Minnesota utilities like Xcel offer rebates/storage incentives through programs like Home Energy Squad or Partners in Energy 

• Energy-Efficient Systems: ENERGY STAR–rated AC units and heat pumps offer long-term savings. Upgrading can qualify you for utility credits and rebates.

• Insulation & Shade Structures: Attic insulation and strategically planted trees or awnings reduce heat gain. Proper attic ventilation also disperses heat buildup.

Minnesota summer means warmth—but it doesn’t have to mean high energy bills. By combining smart thermostat use, fan strategies, window shading, and efficient AC maintenance, you can stay cool—comfortably and cost-effectively.

For immediate savings, adjust fans and cooling schedules. For sustained benefits, consider system upgrades and insulation with rebate support. Tailor these tips to match your home’s layout and energy habits—and enjoy a cooler, more efficient summer.
