You shouldn’t be forced to give up comfort or empty your wallet to keep your house at a refreshing temp during muggy weather.

But what is the right setting, exactly? We discuss recommendations from energy professionals so you can select the best temperature for your family.

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a big difference between your interior and outdoor temps, your electrical expenses will be larger.

This is our advice based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that sounds too high, there are approaches you can keep your house refreshing without having the air conditioner on constantly.

Keeping windows and blinds closed during the day keeps cold air where it should be—indoors. Some window coverings, including honeycomb shades or plantation shutters, are made to give added insulation and improved energy conservation.

If you have ceiling fans in your home, the DOE says you can raise thermostat settings about 4 degrees higher without giving up comfort. That’s since they refresh by a windchill effect. Because they cool people, not spaces, turn them off when you leave a room.

If 78 degrees still seems too hot at first glance, try conducting an experiment for approximately a week. Start by increasing your temperature to 78 degrees while you’re home. Then, steadily lower it while following the ideas above. You may be amazed at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioner working all day while your residence is unoccupied. Switching the setting 7–10 degrees hotter can save you anywhere from 5–15% on your air conditioning bills, according to the DOE.

When you get home, don’t be tempted to put your thermostat colder than 78 to cool your home more rapidly. This isn’t useful and usually produces a bigger cooling bill.

A programmable thermostat is a useful approach to keep your settings in check, but you have to set programs. If you don’t use programs, you might forget to raise the set temperature when you go.

If you need a hassle-free solution, consider buying a smart thermostat. This thermostat connects with your phone, so it realizes when you’re at home and when you’re out. Then it automatically modifies temperature settings for the biggest savings. How much exactly? Usually $180 each year on heating and cooling, according to ENERGY STAR.

Another benefit of getting a smart thermostat? You can use your phone to monitor and change temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that may be unbearable for most families. The majority of people sleep better when their sleeping space is chilled, so that’s why the National Sleep Foundation advises 60–67 degrees. But that could be too cool, due to your PJ and blanket preference.

We recommend running a comparable test over a week, moving your temp higher and slowly lowering it to pick the right temp for your house. On pleasant nights, you could learn keeping windows open at night and running a ceiling fan is a preferable idea than operating the air conditioning.

More Methods to Use Less Energy This Summer

There are extra methods you can conserve money on utility bills throughout hot weather.

  1. Get an energy-efficient AC system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they get older. An upgraded air conditioner can keep your house more comfortable while keeping cooling expenses low.
  2. Set yearly air conditioner service. Routine air conditioner maintenance keeps your equipment operating like it should and may help it operate more efficiently. It may also help extend its life cycle, since it enables technicians to discover little problems before they create a major meltdown.
  3. Put in new air filters regularly. Use manufacturer instructions for replacing your air filter. A clogged filter can result in your system short cycling, or run too frequently, and increase your electricity.
  4. Measure attic insulation levels. Nearly 90% of houses in the United States don’t have adequate insulation, according to the Insulation Institute. Many southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  5. Have your ductwork checked. Ductwork that has separated over time can let cool air into your attic, walls or crawl space. This can create huge comfort troubles in your house, like hot and cold spots.
  6. Seal holes, doors and windows. Keep warm air in its place by sealing openings. You can also caulk or weather strip doors to keep more conditioned air indoors.
