Learn the best temperatures for air conditioning to save money this summer.

We’re in the middle of a massive summer heatwave — Monday, July 22 was the hottest day in recorded history, and Tuesday almost beat that record. All that summer heat leads to more air conditioning — and higher electricity bills.

If you’re trying to save money on your utility bills this summer, it’s essential to optimize your air conditioning. Tweaking your thermostat can end up knocking a big chunk of change off your monthly electrical bill, especially if you set it to the optimized temperatures for hot summer weather.

Below, we’ll outline the best temperature to set your thermostat to save energy during summer and winter. We’ll explain why it works to manage your home’s climate more efficiently and share a few bonus thermostat tricks and heating habits to reduce your overall usage.

What’s the optimal temperature to set your thermostat for summer?

According to the US Department of Energy, the best technique for staying cool yet minimizing utility costs in summer is to keep your home warmer than usual when no one is home and then set the temperature as high as comfortably possible when home. Energy Star, a program of the US Environmental Protection Agency and the US Department of Energy, suggested that homes be kept at 78 degrees Fahrenheit when home during the day. 

It also suggests that the thermostat be set to 82 degrees Fahrenheit when sleeping and 85 degrees Fahrenheit when out of the house for maximum savings; recommendations that were met with scorn and disbelief on social media. 

If setting your thermostat to somewhere in the 80s sounds too warm, then a good rule of thumb to follow is to turn your thermostat up 7 to 10 degrees from your normal setting for eight hours a day, so you can save up to 10% a year.

What’s the best temperature to set your thermostat for winter?

According to the US Department of Energy, it’s best to keep your thermostat at 68 degrees Fahrenheit for most of the day during the winter season. For maximum efficiency, you should also designate eight hours per day during which you turn the temperature down by between 7 and 10 degrees. By following this routine, you may again be able to reduce your yearly energy costs by up to 10%.

Depending on your schedule and comfort preferences, you can decide whether you’d prefer to keep your home cooler during the day or at night. Some people prefer turning the heat down at night when they can cozy up under blankets and won’t notice the colder conditions. Plus, sleeping in chillier temperatures may be linked with getting more restful sleep.

For others, it might make more sense to turn the thermostat down during the daytime when they’re at work. Once you’re home, you can crank up the temperature to a more comfortable level.

Why does your thermostat setting matter?

In summer

A common misconception is that setting your air conditioner to a lower-than-normal temperature will cool your home faster. An air conditioner will only really cool your home to 15 to 20 degrees cooler than the outdoors; any other setting will not cool your home more and will result in unnecessarily high expenses. 

Plus, a higher interior temperature setting in the summer will slow the flow of heat into your home, which results in both energy and money savings. 

In winter

What makes 68 degrees Fahrenheit the best temperature for winter? It’s on the lower end of comfortable indoor temperatures for some people, but there’s a good reason to keep your home cooler during winter. When your home is set to a lower temperature, it will lose heat more slowly than if the temperature were higher. In other words, keeping your home at a cooler indoor temperature will help it retain heat longer and reduce the amount of energy required to keep the house comfortable. As a result, you’ll save energy and money.

How can you position your thermostat for maximum efficiency?

In addition to following these temperature recommendations, you can maximize your energy efficiency by installing your thermostat in the right place. It’s best to position your thermostat away from drafty areas (near vents, doors or windows) and away from places that receive direct sunlight, as these factors could activate your thermostat unnecessarily. Instead, place it on an interior wall in a well-used area of your home.

Have a heat pump? Keep this in mind

Fiddling with your thermostat multiple times per day isn’t ideal, so it’s best to have a smart thermostat or programmable thermostat that lets you set a schedule and automate temperature changes.

Some smart and programmable thermostats don’t work well with heat pumps (a furnace and AC alternative). If you have a heat pump system, ask your HVAC specialist about buying a special type of thermostat that’s designed for use with your system.

What are some other ways to reduce energy costs?

If you’re frustrated with high utility bills, you might be interested in switching to green energy such as solar power. With solar panels, you can generate power yourself, reducing energy costs and your reliance on the public grid. They’re an eco-friendly alternative to traditional energy sources, providing clean power all year long (including in winter) for your home, business or vehicle.

The bottom line

Being smart about your thermostat settings can make a real difference to your energy consumption year-round. By reducing your home’s temperature to 68 degrees Fahrenheit and under during winter and about 78 degrees Fahrenheit during summer, you can conserve energy and cut down your energy bills for good.
