Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to give up comfort or empty your wallet to keep your house at the right setting during warm days.

But what is the best setting, exactly? We review advice from energy experts so you can choose the best setting for your family.

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

Recommended Thermostat Settings for Summer

Most households find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a major difference between your indoor and exterior warmth, your AC bills 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 appears hot, there are methods you can keep your residence pleasant without having the AC running frequently.

Keeping windows and blinds shut during the day keeps chilled air where it should be—inside. Some window treatments, like honeycomb shades or plantation shutters, are designed to offer extra insulation and improved energy efficiency.

If you have ceiling fans in your house, the DOE says you can increase thermostat temperatures about 4 degrees hotter without giving up comfort. That’s due to the fact they refresh through a windchill effect. Since they cool people, not areas, shut them off when you exit a room.

If 78 degrees still feels too hot at first glance, try doing a trial for approximately a week. Start by raising your temperature to 78 degrees while you’re at your house. Then, gradually turn it down while using the suggestions above. You might be astonished at how comfortable you feel at a hotter temperature setting.

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

When you get home, don’t be tempted to switch your thermostat below 78 to cool your home more quickly. This isn’t productive and often leads to a bigger cooling cost.

A programmable thermostat is a good approach to keep your temp controlled, but it requires setting programs. If you don’t set programs, you might forget to change the set temperature when you take off.

If you need a hassle-free fix, consider buying a smart thermostat. This thermostat links with your phone, so it knows when you’re at your house and when you’re out. Then it intuitively changes temperature settings for the biggest savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

Another advantage of using 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 advises 82 degrees, that might be unbearable for many families. Most people sleep better when their sleeping area is chilled, so that’s why the National Sleep Foundation advises 60–67 degrees. But that could be too chilly, due to your pajama and blanket preference.

We recommend using a comparable test over a week, putting your temp higher and progressively turning it down to locate the best setting for your house. On pleasant nights, you might find keeping windows open at night and relying on a ceiling fan is a preferable solution than using the air conditioning.

More Methods to Save Energy This Summer

There are other ways you can save money on AC bills throughout hot weather.

  1. Get an energy-efficient cooling system. Central air conditioners only last about 12–15 years and become less efficient as they get older. An updated air conditioner can keep your residence comfier while keeping utility

  3. Set regular air conditioner maintenance. Regular air conditioner maintenance keeps your equipment running properly and might help it run at greater efficiency. It might also help lengthen its life cycle, since it enables pros to uncover small problems before they create a big meltdown.
  4. Put in new air filters frequently. Follow manufacturer instructions for switching your air filter. A dusty filter can lead to your system short cycling, or turn on and off too much, and increase your electrical
  5. expenses.
  6. Inspect attic insulation levels. Almost 90% of homes in the USA don’t have proper insulation, according to the Insulation Institute. Many southern climates require 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork checked. Ductwork that has loosened as it’s aged can let cold air into your attic, walls or crawl space. This can result in big comfort troubles in your house, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep warm air where it belongs by sealing openings. You can also caulk or weather strip doors to seal more cool air indoors.
