Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to give up comfort or drain your wallet to keep your home at the right temperature during summer weather.

But what is the ideal temperature, exactly? We go over advice from energy pros so you can choose the best setting for your loved ones.

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

Recommended Thermostat Settings for Summer

Most households find setting the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your interior and exterior warmth, your AC expenses will be greater.

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

While at home: 78 degrees. While that appears warm, there are methods you can keep your house pleasant without having the air conditioning on frequently.

Keeping windows and curtains shut during the day keeps cool air where it belongs—indoors. Some window solutions, like honeycomb shades or plantation shutters, are designed to give extra insulation and better energy savings.

If you have ceiling fans in your residence, the DOE says you can increase thermostat temps about 4 degrees hotter without sacrificing comfort. That’s since they freshen by a windchill effect. As they cool people, not areas, switch them off when you exit a room.

If 78 degrees still appears too uncomfortable on the surface, try doing a trial for a week or so. Start by increasing your thermostat to 78 degrees while you’re at your residence. Then, gradually turn it down while using the tips above. You may be astonished at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no rationale for keeping the AC going all day while your residence is unoccupied. Turning the temperature 7¬¬–10 degrees warmer can save you an estimated 5–15% on your cooling costs, according to the DOE.

When you arrive home, don’t be tempted to set your thermostat below 78 to cool your residence faster. This isn’t effective and usually results in a more expensive AC expense.

A programmable thermostat is a helpful way to keep your temp under control, but you need to set programs. If you don’t utilize programs, you risk forgetting to change the set temperature when you go.

If you need a hassle-free solution, consider getting a smart thermostat. This thermostat works with with your phone, so it realizes when you’re at your residence and when you’re away. Then it automatically adjusts temperature settings for the best savings. How much exactly? About $180 each year 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 adjust temperature settings from nearly anywhere.

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

We recommend following a similar test over a week, moving your temp higher and steadily decreasing it to locate the best setting for your family. On mild nights, you may learn keeping windows open at night and relying on a ceiling fan is a superior option than operating the air conditioning.

More Methods to Conserve Energy During Warm Weather

There are other approaches you can spend less money on cooling 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. A new air conditioner can keep your house cooler while keeping energy
  2. expenses small.
  3. Set yearly air conditioner maintenance. Routine air conditioner maintenance keeps your unit running smoothly and may help it run at greater efficiency. It may also help lengthen its life span, since it allows technicians to spot seemingly insignificant problems before they lead to an expensive meltdown.
  4. Replace air filters frequently. Follow manufacturer instructions for switching your air filter. A dirty filter can lead to your system short cycling, or switch on and off too much, and raise your cooling
  5. expenses.
  6. Inspect attic insulation levels. Nearly 90% of residences in the USA 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 separated over the years can let cold air into your attic, walls or crawl space. This can result in big comfort troubles in your residence, including hot and cold spots.
  8. Seal holes, doors and windows. Keep hot air in its place by sealing openings. You can also caulk or weather strip doors to trap more cool air inside.
