Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to sacrifice comfort or spend a lot to keep your home at a pleasant temp during hot days.

But what is the ideal temp, exactly? We go over ideas from energy experts so you can find the best setting for your house.

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

Recommended Thermostat Settings for Summer

Most families find placing the thermostat at 72-73 degrees is ideal. However, if there’s a major difference between your inside and exterior temperatures, your cooling bills will be higher.

These are our suggestions 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 cool without having the AC running all the time.

Keeping windows and curtains shut during the day keeps cool air where it needs to be—indoors. Some window solutions, such as honeycomb shades or plantation shutters, are made to give more insulation and better energy savings.

If you have ceiling fans in your residence, the DOE says you can raise thermostat temps about 4 degrees warmer without compromising comfort. That’s because they refresh through a windchill effect. Since they cool people, not rooms, switch them off when you exit a room.

If 78 degrees still appears too warm initially, try doing a trial for about a week. Begin by raising your temperature to 78 degrees while you’re at your residence. Then, progressively decrease it while using the suggestions above. You could be astonished at how comfortable you feel at a hotter temperature setting.

While away: 88 degrees. There’s no rationale for keeping the air conditioning on all day while your house is vacant. Moving the setting 7¬¬–10 degrees higher can save you as much as 5–15% on your electrical expenses, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat colder than 78 to cool your residence more rapidly. This isn’t useful and usually results in a bigger electrical bills.

A programmable thermostat is a useful way to keep your settings in check, but you need to set programs. If you don’t use programs, you run the risk of forgetting to raise the set temperature when you leave.

If you’re looking for a convenient fix, consider buying a smart thermostat. This thermostat connects with your phone, so it knows when you’re at your residence and when you’re gone. Then it instinctively adjusts temperature settings for the best savings. How much exactly? Typically $180 annually on heating and cooling, according to ENERGY STAR.

Another benefit of getting a smart thermostat? You can use your phone to keep an eye on and change temperature settings from just about anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that could be too uncomfortable for most families. Many people sleep better when their sleeping space is chilled, so that’s why the National Sleep Foundation advises 60–67 degrees. But that may be too cold, based on your pajama and blanket preference.

We recommend using a comparable test over a week, setting your thermostat higher and steadily decreasing it to choose the ideal temperature for your house. On cool nights, you could find keeping windows open at night and relying on a ceiling fan is a preferable option than using the AC.

More Methods to Save Energy During Hot Weather

There are extra ways you can spend less money on AC bills throughout hot weather.

  1. Buy an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and lose efficiency as they become older. An updated air conditioner can keep your home more comfortable while keeping cooling
  2. expenses small.
  3. Schedule yearly air conditioning tune-ups. Routine air conditioner maintenance keeps your system operating properly and could help it run more efficiently. It might also help lengthen its life span, since it enables techs to pinpoint small troubles before they create an expensive meltdown.
  4. Switch air filters frequently. Follow manufacturer instructions for replacing your air filter. A dusty filter can cause your system to short cycle, or run too frequently, and drive up your electricity
  5. bills.
  6. Measure attic insulation levels. Almost 90% of houses in the United States don’t have adequate insulation, according to the Insulation Institute. Many southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork checked. Ductwork that has come apart over time can seep cold air into your attic, walls or crawl space. This can lead to major comfort problems in your home, including hot and cold spots.
  8. Seal holes, doors and windows. Keep muggy air in its place by sealing cracks. You can also caulk or weather strip doors to seal more cold air inside.
