15 Energy Saving Tips for Homeowners in Summer

Summer Energy Use & Minnesota’s Unique Climate

According to the U.S. Energy Information Administration, air conditioning accounts for about 12% of a home’s total summer energy use nationwide. In Minnesota, where hot, humid days can quickly turn into cool, breezy evenings, homeowners often find themselves running HVAC systems harder than necessary. The question becomes: How do you stay comfortable without sending your utility bills soaring?*

There’s no single “best” way to save energy — instead, the key is a combination of quick wins, smart upgrades, and long-term investments tailored to your home. Below, you’ll find practical energy saving tips for summer designed for Minnesota’s unique climate.

Quick, No-Cost Changes

You don’t need to spend a dime to start saving energy today. These small adjustments can cut cooling costs by 5–20%:

• Adjust Your Thermostat

Set to 78°F when home and 85°F when away. Each degree warmer can reduce cooling costs by 3–5%.

• In Minnesota, this means less strain on your AC during mild evenings.

• Use Ceiling & Portable Fans

Fans don’t lower air temperature — they make you feel 4–6°F cooler.

• Run counterclockwise in summer to push cool air down.

• Close Blinds & Curtains During Peak Sun Hours

Especially important for south- and west-facing windows.

• Can reduce indoor heat gain by up to 77%.

• Cook Outdoors or Use Small Appliances

Ovens can raise indoor temps by 5–10°F, making your AC work harder.

• Opt for grills, microwaves, or slow cookers.

• Unblock Air Vents & Returns

Furniture, rugs, or boxes over vents reduce airflow and efficiency.

• Ensure returns are clear for balanced air pressure.

• Run Heat-Producing Appliances at Night

Dishwashers, dryers, and washers add heat and humidity.

• Evening use avoids peak load and cooling demand.

Low-Cost Upgrades

Investing $20–$300 in strategic changes can yield noticeable drops in your energy bill:

• Install a Programmable or Smart Thermostat

Saves $50–$180 annually by aligning cooling with your schedule.

• Many models integrate with smartphone apps for easy adjustments.

• Seal Air Leaks Around Windows & Doors

Use weatherstripping for movable joints and caulk for stationary seams.

• Stops warm air infiltration and keeps cool air inside.

• Upgrade to LED Lighting

LEDs emit very little heat and use 80% less energy than incandescents.

• Swap high-use bulbs first for fastest ROI.

• Add Reflective Window Film

Blocks UV rays and reduces solar heat gain.

• Particularly effective on sunny exposures.

• Replace or Clean AC Filters

Dirty filters can increase cooling costs by up to 15%.

• In summer, replace monthly or as recommended by your system’s manual.

Bigger Investments for Long-Term Savings

For maximum home energy efficiency upgrades, focus on projects with lasting returns.

• Add or Upgrade Attic Insulation

Insulation keeps heat out in summer and in during winter.

• The U.S. DOE recommends R-49 to R-60 for Minnesota attics.

• Replace Old Windows with Energy-Efficient Models

ENERGY STAR® windows can cut energy bills by 12% nationwide.

• Low-E coatings reduce solar gain without blocking light.

• Upgrade Your HVAC System

New units can be up to 50% more efficient than 20-year-old models.

• Look for SEER2 ratings of 15 or higher for Minnesota’s climate.

• Take Advantage of Minnesota Energy Rebates

The Home Energy Rebates Program can offset costs for insulation, windows, and high-efficiency HVAC.

• Combine rebates with manufacturer incentives for even greater savings.

Common Mistakes That Drive Up Summer Bills

• Cooling unoccupied rooms without closing vents or adjusting zoning
• Blocking return air vents with furniture
• Skipping seasonal HVAC maintenance
• Setting thermostat extremely low after coming home (cools no faster, costs more)
