Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to give up comfort or empty your wallet to keep your house at a pleasant temperature during the summer.

But what is the right temp, exactly? We discuss ideas from energy specialists so you can select the best temperature for your residence.

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees is ideal. However, if there’s a big difference between your indoor and outside temps, your cooling costs will be higher.

These are our recommendations 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 home cool without having the air conditioning running frequently.

Keeping windows and blinds shut during the day keeps chilled air where it belongs—indoors. Some window coverings, such as honeycomb shades or plantation shutters, are designed to give more insulation and enhanced energy efficiency.

If you have ceiling fans in your residence, the DOE says you can raise thermostat temps about 4 degrees higher without giving up comfort. That’s since they refresh through a windchill effect. As they cool people, not rooms, shut them off when you move from a room.

If 78 degrees still appears too warm on the surface, try doing a test for a week or so. Begin by raising your temperature to 78 degrees while you’re at your residence. Then, steadily lower it while adhering to the tips above. You might be amazed at how cool you feel at a higher temperature setting.

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

When you get home, don’t be tempted to put your thermostat under 78 to cool your home more quickly. This isn’t useful and typically leads to a more expensive electrical expense.

A programmable thermostat is a good method to keep your temperature in check, but you need to set programs. If you don’t set programs, you risk forgetting to change the set temperature when you take off.

If you need a hassle-free resolution, think about buying a smart thermostat. This thermostat works with with your phone, so it is aware when you’re at home and when you’re out. Then it instinctively adjusts temperature settings for maximum savings. How much exactly? Usually $180 yearly on heating and cooling, according to ENERGY STAR.

Another perk of installing a smart thermostat? You can use your phone to keep an eye on and regulate temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that could be unpleasant for many families. Most people sleep better when their sleeping area is cold, so that’s why the National Sleep Foundation advises 60–67 degrees. But that may be too chilly, based on your PJ and blanket preference.

We recommend using an equivalent test over a week, moving your temperature higher and progressively decreasing it to choose the ideal temperature for your residence. On cool nights, you may discover keeping windows open at night and relying on a ceiling fan is a superior solution than running the air conditioning.

More Ways to Save Energy During Hot Weather

There are added methods you can spend less money on air conditioning bills throughout warm weather.

  1. Install an energy-efficient air conditioning system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they become older. A new air conditioner can keep your home more comfortable while keeping electrical
  2. bills down.
  3. Book regular air conditioning maintenance. Annual air conditioner maintenance keeps your unit working properly and may help it run at better efficiency. It can also help extend its life cycle, since it allows pros to uncover seemingly insignificant troubles before they cause a big meltdown.
  4. Replace air filters frequently. Follow manufacturer instructions for changing your air filter. A dusty filter can result in your system short cycling, or turn on and off too frequently, and drive up your utility
  5. expenses.
  6. Inspect attic insulation levels. Nearly 90% of homes in the U.S. don’t have proper insulation, according to the Insulation Institute. Many southern climates require 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork inspected. Ductwork that has loosened over time can leak cool air into your attic, walls or crawl space. This can create huge comfort troubles in your house, such as hot and cold spots.
  8. Seal holes, doors and windows. Keep hot air in its place by sealing holes. You can also caulk or weather strip doors to seal more conditioned air inside.
