It’s no secret that July and August in Southeast Michigan bring hot, humid days and warm, muggy nights. Whether you live in Howell, Brighton, Ann Arbor, or surrounding communities, your air conditioner is probably working overtime—and your energy bills may be creeping up right along with the temperatures.
At AAA Service Network, we understand how important it is to stay comfortable without draining your bank account. With just a few adjustments and smart energy habits, you can lower your utility bills, keep your home cool, and reduce wear and tear on your AC system.
Here’s how to beat the heat—and high costs—during Southeast Michigan’s peak summer season.
1. Be Strategic with Your Cooling Schedule
During the hottest part of the day—typically between 2 p.m. and 7 p.m.—energy demand skyrockets as your AC works harder than ever. That’s also when your electricity is most expensive, especially if you’re on time-of-use pricing.
Here’s how to work around that:
- Pre-cool your home in the morning when outdoor temperatures are lower.
- Set your thermostat to 72–74°F in the early hours, then bump it up to 78–80°F during peak hours. Keep comfort and health in mind when choosing the temperature settings.
- Use fans to maintain comfort even at higher thermostat settings.
Pro tip: Ceiling fans make you feel up to 4°F cooler and cost just pennies a day to run.
2. Reduce Heat Inside the Home
While your AC battles the summer heat, don’t make its job harder from the inside.
Try these energy-smart habits:
- Avoid using the oven during the day. Grill outdoors, use a slow cooker, or prep cold meals instead.
- Run dishwashers, laundry machines, and dryers in the early morning or late evening.
- Switch to LED bulbs—they emit far less heat than incandescent lights.
- Unplug electronics and chargers when not in use to avoid extra heat and phantom energy draw.
These small steps not only cut energy use, but they keep your living space cooler throughout the day.
3. Block the Sun, Seal the Cool
Direct sunlight streaming through your windows can dramatically raise indoor temperatures—and cause your AC to work harder to keep up.
Keep the sun out and the cool in by:
- Closing blinds or curtains on east-facing windows in the morning and west-facing windows in the afternoon.
- Installing blackout curtains or thermal shades in rooms that get a lot of sun.
- Sealing gaps around windows and doors with weatherstripping or caulk to prevent cool air from leaking out.
- Adding insulation to your attic or crawlspace if your home feels hard to cool. A properly insulated attic can block heat transfer and help your AC run less.
You’ll notice a difference not just in comfort—but in your utility bill.
4. Keep Your AC System Running Efficiently
A well-maintained air conditioner runs more efficiently, cools more effectively, and breaks down less often. If you haven’t scheduled AC maintenance this year, mid-summer is still a great time to do it.
Here’s how to help your system perform at its best:
- Replace your air filter every 30 days (depending on the type of filter) during peak summer months. A dirty filter restricts airflow, causing your system to overwork.
- Clear debris from around your outdoor AC unit, including leaves, weeds, or fencing that blocks airflow.
- Schedule a professional tune-up with a licensed HVAC technician. They’ll check refrigerant levels, inspect electrical connections, clean coils, and make sure everything’s running safely and efficiently.
Routine maintenance can improve your system’s efficiency by up to 15% and extend its lifespan.
5. Use a Smart Thermostat to Your Advantage
If your home doesn’t have a smart thermostat yet, this could be a great time to upgrade. These devices are easy to use, conserve energy automatically, and often qualify for rebates through local utility providers.
Benefits of smart thermostats include:
- Automatic temperature adjustments based on your habits and preferences.
- Remote control through your smartphone—perfect if you forget to adjust the AC before heading out.
- Energy usage reports to help you spot opportunities to save even more.
- Geofencing features that cool your home when you’re on the way and conserve energy while you’re away.
Many models are ENERGY STAR® certified and compatible with utility rebate programs in Southeast Michigan.
6. Take Advantage of Cooler Evenings
While Michigan summer days can be scorching, the nights often bring a much-needed break in temperature—especially in late July and early August. Make the most of it by letting your home breathe.
Once the sun goes down:
- Open windows on opposite sides of your home to create a natural cross-breeze.
- Use box or window fans to pull cooler air in. Make sure to check the air quality first.
- Turn off your AC entirely at night if the outdoor temperatures allow.
Natural ventilation helps flush out trapped heat, giving your AC a well-deserved rest to prevent overworking.
7. Explore Long-Term Efficiency Upgrades
If your air conditioner is more than 12–15 years old or consistently struggles to cool your home, it might be time to consider a replacement. Today’s high-efficiency systems use less energy and offer much better performance—even in extreme heat.
Other upgrades that can improve long-term energy savings:
- Energy-efficient windows to reduce solar heat gain.
- Better attic ventilation, such as solar attic fans.
- Upgraded insulation in walls, crawlspaces, or rim joists.
- Seal and repair ducts to prevent leaks.
