Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to compromise on comfort or drain your wallet to keep your residence at a pleasant temp during muggy weather.

But what is the ideal setting, exactly? We review ideas from energy pros so you can determine the best temp for your house.

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

Recommended Thermostat Settings for Summer

Most people find placing the thermostat at 72-73 degrees is ideal. However, if there’s a sizeable difference between your inside and outside temperatures, your AC bills will be bigger.

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 ways you can keep your home pleasant without having the air conditioner running all the time.

Keeping windows and blinds closed during the day keeps cool air where it should be—indoors. Some window treatments, including honeycomb shades or plantation shutters, are designed to deliver extra insulation and better energy savings.

If you have ceiling fans in your house, the DOE says you can increase thermostat temps about 4 degrees hotter without giving up comfort. That’s since they cool by a windchill effect. Since they cool people, not spaces, turn them off when you leave a room.

If 78 degrees still appears too uncomfortable at first glance, try doing an experiment for approximately a week. Start by upping your thermostat to 78 degrees while you’re at your house. Then, gradually turn it down while using the advice above. You might be shocked at how comfortable you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner running all day while your residence is vacant. Moving the temperature 7¬¬–10 degrees hotter can save you an estimated 5–15% on your air conditioning bills, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat below 78 to cool your residence more rapidly. This isn’t effective and typically results in a bigger cooling cost.

A programmable thermostat is a useful method to keep your temp controlled, but you have to set programs. If you don’t utilize programs, you might forget to increase the set temperature when you go.

If you want a convenient remedy, think over installing a smart thermostat. This thermostat works with with your phone, so it knows when you’re at your house and when you’re gone. Then it intuitively adjusts temperature settings for the biggest savings. How much exactly? About $180 each year on heating and cooling, according to ENERGY STAR.

Another advantage of having a smart thermostat? You can use your phone to keep an eye on and change temperature settings from nearly anywhere.

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

We suggest running a similar test over a week, moving your thermostat higher and gradually decreasing it to choose the best setting for your residence. On cool nights, you might discover keeping windows open at night and running a ceiling fan is a superior idea than operating the AC.

More Ways to Use Less Energy During Warm Weather

There are other ways you can conserve money on cooling bills throughout the summer.

  1. Install an energy-efficient air conditioning system. Central air conditioners only last about 12–15 years and get less efficient as they become older. An updated air conditioner can keep your house cooler while keeping cooling
  2. bills small.
  3. Set regular AC tune-ups. Annual air conditioner maintenance keeps your unit running like it should and may help it work at better efficiency. It might also help lengthen its life cycle, since it enables techs to discover small problems before they create a big meltdown.
  4. Replace air filters often. Read manufacturer instructions for switching your air filter. A dirty filter can cause your system to short cycle, or switch on and off too much, and drive up your utility
  5. costs.
  6. Measure attic insulation levels. Almost 90% of residences in the USA don’t have enough insulation, according to the Insulation Institute. Most southern climates require 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork checked. Ductwork that has come apart over time can let cold air into your attic, walls or crawl space. This can create major comfort issues in your home, such as hot and cold spots.
  8. Seal holes, doors and windows. Keep humid air where it should be by sealing openings. You can also caulk or weather strip doors to seal more cool air inside.
