How to Stay Cool with Your HVAC in a Minnesota Summer: Local Tips for Comfort & Efficiency

Summer in Minnesota can be beautiful—but also brutally hot and humid. Whether you're in the Twin Cities, Duluth, or out in Greater Minnesota, your HVAC system works overtime to keep your home comfortable. But cooling your home efficiently isn’t just about cranking the AC. It’s about working with the system you have, maintaining it smartly, and using a few community-tested tricks to keep your space cool without burning a hole in your wallet.

Here’s how to stay cool and stress-free this summer—with HVAC strategies that work in Minnesota’s unique climate.

1. Schedule a Seasonal HVAC Tune-Up 
Your HVAC system might’ve hibernated through a long winter, but Minnesota summers demand just as much attention. Schedule an HVAC check-up in late spring to:

• Ensure your system is running efficiently before peak heat
• Catch worn-out parts before they fail
• Prevent mid-summer breakdowns 

Local tip: In Minnesota, humidity can be just as punishing as heat. Ask your technician to check your system’s dehumidifying performance, too.

​
2. Optimize Your Thermostat for Minnesota’s Temperature Swings
Summer days can hit 90°F while evenings cool off. A programmable or smart thermostat helps manage these fluctuations automatically.

Try setting:

• 78°F when you’re home
• 85°F when you’re away
• 72–74°F for sleeping comfort 

Many Minnesota utilities offer rebates for installing smart thermostats—check with Xcel Energy or Minnesota Power.


3. Change Your Filters—Especially if You’ve Got Allergies or Pets
In a state where spring pollen meets summer dust and dander, air filters clog quickly. Change them every 1–2 months in summer to keep air flowing freely and reduce allergens.

If you live in a rural or lake area with more open windows and dust, check filters even more frequently.


4. Seal Air Leaks for Maximum Efficiency
Minnesota homes, especially older ones, are notorious for air leaks around windows, doors, and basements. Don’t let that cool air escape! Weather-stripping, caulking, and even thermal curtains can reduce the strain on your AC.

Community tip: Ask your city or utility provider about home energy audits—many Minnesota communities offer them free or at a discount.


5. Keep Outdoor Units Clear from Debris 
By June, your outdoor condenser may be covered in cottonwood fluff, maple seeds, or overgrown shrubs. A quick cleanup can improve performance and prevent overheating.

• Trim vegetation within 2 feet
• Rinse coils with a hose (gently!)
• Clear off pollen buildup from nearby trees
  
  
  

6. Run Ceiling Fans the Right Way
Ceiling fans can make your home feel 4–6 degrees cooler—but only if they’re spinning counterclockwise in summer. This creates a breeze that complements your AC.
​

7. Plan Your Chores Around the Heat
Ovens, dryers, and dishwashers give off heat that competes with your AC. During Minnesota's warmest months (July and August), run major appliances in the early morning or late evening.


8. Upgrade If Your HVAC System Is Over 12 Years Old
Minnesota’s extreme seasonal shifts take a toll on HVAC systems. If yours is over 12–15 years old, it may be time to upgrade to a more energy-efficient model.
