Whats the Most Energy-Efficient AC Setting?

You shouldn’t have to give up comfort or spend a lot to keep your house at a pleasant setting during warm days.

But what is the right temperature, exactly? We review ideas from energy professionals so you can determine the best temp for your house.

Here’s what we suggest for the most energy-efficient setting for air conditioning in Grand Prairie.

Recommended Thermostat Settings for Summer

Most households find setting the thermostat at 72-73 degrees is ideal. However, if there’s a huge difference between your inside and outdoor temperatures, your electrical expenses will be higher.

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

While at home: 78 degrees. While that seems too high, there are methods you can keep your residence refreshing without having the AC going constantly.

Keeping windows and window treatments shut during the day keeps cool air where it should be—within your home. Some window treatments, such as honeycomb shades or plantation shutters, are made to provide more insulation and improved energy efficiency.

If you have ceiling fans in your residence, the DOE says you can move thermostat settings about 4 degrees higher without sacrificing comfort. That’s because they refresh by a windchill effect. Since they cool people, not spaces, switch them off when you leave a room.

If 78 degrees still feels too warm at first glance, try conducting a trial for a week or so. Start by increasing your temperature to 78 degrees while you’re home. Then, progressively decrease it while using the advice above. You could be shocked at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no reason to keep the AC running all day while your house is vacant. Switching the setting 7¬¬–10 degrees higher can save you anywhere from 5–15% on your AC expenses, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat below 78 to cool your home faster. This isn’t useful and often leads to a more expensive air conditioner expense.

A programmable thermostat is a good approach to keep your temperature under control, but it requires setting programs. If you don’t use programs, you risk forgetting to change the set temperature when you leave.

If you need a convenient resolution, consider installing a smart thermostat. This thermostat works with with your phone, so it is aware when you’re at your residence and when you’re out. Then it intuitively adjusts temperature settings for maximum savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

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

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that might be unpleasant for most families. Most people sleep better when their sleeping space is chilly, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that could be too chilly, depending on your pajama and blanket preference.

We advise using an equivalent test over a week, putting your temp higher and steadily turning it down to pinpoint the right temperature for your residence. On cool nights, you might learn keeping windows open at night and using a ceiling fan is a preferable idea than running the AC.

More Approaches to Save Energy During Hot Weather

There are added approaches you can spend less money on cooling bills throughout hot weather.

  1. Upgrade to an energy-efficient cooling system. Central air conditioners only are effective for about 12–15 years and get less efficient as they age. An upgraded air conditioner can keep your home more comfortable while keeping AC
  2. costs small.
  3. Schedule yearly air conditioner service. Routine air conditioner maintenance keeps your system operating like it should and might help it run at greater efficiency. It could also help lengthen its life cycle, since it helps techs to discover little troubles before they create an expensive meltdown.
  4. Put in new air filters regularly. Read manufacturer instructions for switching your air filter. A clogged filter can result in your system short cycling, or switch on and off too frequently, and drive up your electricity
  5. bills.
  6. Measure attic insulation levels. Almost 90% of residences in the United States don’t have enough 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 examined. Ductwork that has separated over time can let cool air into your attic, walls or crawl space. This can lead to huge comfort troubles in your residence, including hot and cold spots.
  8. Seal cracks, doors and windows. Keep humid air in its place by sealing holes. You can also caulk or weather strip doors to keep more conditioned air inside.
