Whats the Most Energy-Efficient AC Setting?

You shouldn’t need to compromise on comfort or empty your wallet to keep your house at the right setting during muggy weather.

But what is the right setting, exactly? We review advice from energy professionals so you can select the best setting for your house.

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

Recommended Thermostat Settings for Summer

Most people find using the thermostat at 72-73 degrees is ideal. However, if there’s a sizeable difference between your inside and outdoor temperatures, your cooling costs will be greater.

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

While at home: 78 degrees. While that seems hot, there are methods you can keep your house refreshing without having the AC going frequently.

Keeping windows and window treatments down during the day keeps chilled air where it needs to be—inside. Some window treatments, like honeycomb shades or plantation shutters, are designed to give extra insulation and improved energy savings.

If you have ceiling fans in your residence, the DOE says you can increase thermostat settings about 4 degrees hotter without giving up comfort. That’s because they freshen with a windchill effect. Since they cool people, not rooms, switch them off when you leave a room.

If 78 degrees still seems too warm initially, try running a trial for approximately a week. Get started by upping your temperature to 78 degrees while you’re at your house. Then, gradually turn it down while using the suggestions above. You might be shocked at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner running all day while your home is vacant. Moving the setting 7¬¬–10 degrees higher can save you anywhere from 5–15% on your electricity bills, according to the DOE.

When you get home, don’t be tempted to put your thermostat below 78 to cool your house more quickly. This isn’t useful and typically results in a more expensive AC expense.

A programmable thermostat is a helpful method to keep your temperature in check, but you have to set programs. If you don’t set programs, you run the risk of forgetting to move the set temperature when you take off.

If you need a hassle-free solution, think over installing a smart thermostat. This thermostat connects with your phone, so it is aware when you’re at your residence and when you’re gone. Then it instinctively changes temperature settings for maximum savings. How much exactly? Usually $180 each year on heating and cooling, according to ENERGY STAR.

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

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that may be unpleasant for many families. Many people sleep better when their sleeping area is chilly, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that might be too chilly, due to your clothing and blanket preference.

We advise trying an equivalent test over a week, setting your thermostat higher and steadily lowering it to locate the right temp for your residence. On pleasant nights, you could learn keeping windows open at night and running a ceiling fan is a preferable idea than using the air conditioner.

More Methods to Use Less Energy During Hot Weather

There are added ways you can save money on air conditioning bills throughout the summer.

  1. Get an energy-efficient cooling system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they age. An updated air conditioner can keep your house cooler while keeping AC
  2. bills small.
  3. Book regular air conditioner maintenance. Annual air conditioner maintenance keeps your unit running like it should and could help it operate at better efficiency. It can also help prolong its life span, since it allows technicians to pinpoint little problems before they lead to a big meltdown.
  4. Replace air filters regularly. Read manufacturer instructions for switching your air filter. A dirty filter can cause your system to short cycle, or turn on and off too frequently, and drive up your electrical
  5. bills.
  6. Inspect attic insulation levels. Just about 90% of homes in the USA don’t have adequate insulation, according to the Insulation Institute. The majority of southern climates need 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork checked. Ductwork that has come apart as it’s aged can leak cold air into your attic, walls or crawl space. This can create huge comfort troubles in your residence, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep hot air where it should be by closing openings. You can also caulk or weather strip doors to keep more cold air indoors.
