How to Set Your Thermostat and Save Money in Summer

May 23, 2023

Everyone’s always looking to save money on their utility bills, but you should know there’s a way to keep costs down, even when you're out of the house.

The secret is your thermostat. By using automatic schedules, you can help the thermostat plan for your preferred temperatures. This means establishing various temperature settings for when you’re at home, away or even when you’re asleep.

With a few simple adjustments, you have more time to enjoy pleasant temperatures while also keeping more of your money. Check out our guide on how your thermostat can save you money in the summer:

While at Home

Pretty much whenever you're home, you want to enjoy a comfortable temperature. For the most part, you probably have your thermostat lower in the summer while you are in the house to make the most of the cool air.

But the most energy-efficient temperatures for when you're in your home during the summer is in fact anywhere between 78 and 80 degrees Fahrenheit. With this adjustment, you'll avoid the worst of summer while still lowering your monthly energy bill.

While Out of the House

When it comes to setting the temperature for whenever you're gone, it's extremely common to move the thermostat higher for while they're gone.

If your home is in a shady spot in a cooler climate, you can set the temperature as high as 88 degrees while no one is home before lowering it back to the sweet spot of 78-80 degrees after you return. This way, your air conditioning unit won’t be working overtime to provide cooling for a bunch of empty rooms.

While Asleep

To enjoy a good night's sleep during the summer, you want your thermostat set at a comfortable temperature. A great place to start is between 68-72 degrees Fahrenheit. This will keep you from getting too hot or too cold at some point overnight.

Other Strategies for Lowering Energy Use:

  • Install a smart thermostat: Using a smart thermostat in the summer helps save money on energy costs by automatically adjusting to your lifestyle and idea of what comfortable is. A smart thermostat manages the temperature if you are home or sleeping, before allowing it to warm up when the house is empty. With reliable brands like the Lennox iComfort, you have the ability to remotely access and change the temperature through your smartphone, tablet or laptop. Planning smart thermostat installation in your Des Moines home is an effortless way to set the correct temperature whether you're at home or across the country.
  • Update your existing HVAC system: A high-efficiency HVAC system can save money in the long run. If a system boasts high energy efficiency, you can also count on lower utility bills since more efficient equipment requires less energy to achieve comfortable temperatures. Air conditioning installation in Des Moines is a breeze for experienced professionals.
  • Keep up with AC maintenance: Investing in or ignoring regular air conditioning maintenance in Des Moines can have a significant impact on your utility bills. By regularly cleaning the coils, checking for damage and keeping vents clear of dust and debris, this can help your HVAC system run more efficiently. More efficient operation reduces strain on important or delicate components and lowers operational costs, leading to lower energy usage, which translates into lower energy bills.
  • Clean or replace the air filter on a regular basis: Cleaning or replacing the air filter regularly saves money by improving airflow. When filters are clogged with dirt and debris, an AC unit has to work harder, and the added strain may impact the system’s life span and cause breakdowns.
  • Check your attic insulation: Insulation is a vital part of maintaining an energy-efficient home, keeping the hot air outside and the cool air inside during the summer. The North American Insulation Manufacturers Association (NAIMA) recommends that homes in the southern United States should install at least 13-14 inches of insulation, while states further north need 16-18 inches.
  • Review your ventilation: Damage to the ventilation is capable of increasing your energy bills much more than 20 percent, plus it can also lead to problems with your water heater, clothes dryer and other appliances throughout your home. Checking your ductwork for leaks and sealing them can address both concerns.
  • Seal all other leaky spots in your home: Sealing up other leaks in your home with caulk, foam sealant or weather-stripping helps keep things cooler during those hot summer days. You should also check for any gaps around windows, doors and even outdoor fixtures. Taking the time to seal up any leaks now can help you save a lot in the long run.
