You shouldn’t need to sacrifice comfort or empty your wallet to keep your residence at a refreshing temp during the summer.

But what is the ideal setting, exactly? We go over advice from energy experts so you can select the best setting for your residence.

Here’s what we advise for the most energy-efficient setting for air conditioning in The Bay Area.

Recommended Thermostat Settings for Summer

Most people find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your interior and outside temps, your AC expenses will be bigger.

These are our recommendations based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that appears warm, there are approaches you can keep your home refreshing without having the air conditioning running frequently.

Keeping windows and window treatments down during the day keeps chilled air where it should be—within your home. Some window treatments, like honeycomb shades or plantation shutters, are made to offer extra insulation and enhanced energy efficiency.

If you have ceiling fans in your residence, the DOE says you can move thermostat settings about 4 degrees hotter without sacrificing comfort. That’s because they freshen through a windchill effect. As they cool people, not rooms, turn them off when you exit a room.

If 78 degrees still seems too hot at first glance, try conducting a test for approximately a week. Start by raising your setting to 78 degrees while you’re home. Then, steadily decrease it while adhering to the suggestions above. You might be amazed at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioner going all day while your house is unoccupied. Turning the setting 7–10 degrees warmer can save you as much as 5–15% on your electricity bills, according to the DOE.

When you come home, don’t be tempted to put your thermostat colder than 78 to cool your house more rapidly. This isn’t effective and typically results in a higher cooling expense.

A programmable thermostat is a good way to keep your temp in check, but it requires setting programs. If you don’t use programs, you run the risk of forgetting to move the set temperature when you leave.

If you’re looking for a hassle-free remedy, think about installing a smart thermostat. This thermostat links with your phone, so it knows when you’re at your residence and when you’re out. Then it automatically modifies temperature settings for maximum savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

Another benefit of installing a smart thermostat? You can use your phone to watch and adjust temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that might be unpleasant for most families. The majority of people sleep better when their bedroom is chilled, so that’s why the National Sleep Foundation advises 60–67 degrees. But that could be too chilly, based on your PJ and blanket preference.

We advise trying an equivalent test over a week, setting your temp higher and progressively turning it down to pinpoint the ideal temperature for your residence. On pleasant nights, you could learn keeping windows open at night and using a ceiling fan is a preferable idea than running the AC.

More Ways to Use Less Energy During Hot Weather

There are other ways you can spend less money on air conditioning bills throughout the summer.

  1. Install an energy-efficient cooling system. Central air conditioners only last about 12–15 years and get less efficient as they become older. An updated air conditioner can keep your residence more comfortable while keeping cooling costs small.
  2. Book yearly air conditioner maintenance. Annual air conditioner maintenance keeps your equipment running smoothly and may help it run at greater efficiency. It may also help extend its life cycle, since it helps techs to pinpoint little problems before they create a major meltdown.
  3. Put in new air filters regularly. Follow manufacturer instructions for switching your air filter. A dirty filter can cause your system to short cycle, or run too frequently, and increase your electricity.
  4. Check attic insulation levels. Nearly 90% of residences in the USA don’t have enough insulation, according to the Insulation Institute. Many southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  5. Have your ductwork checked. Ductwork that has loosened over time can leak cold air into your attic, walls or crawl space. This can lead to huge comfort troubles in your home, including hot and cold spots.
  6. Seal holes, doors and windows. Keep hot air in its place by plugging cracks. You can also caulk or weather strip doors to seal more cool air within your home.
