Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or spend a lot to keep your residence at a refreshing temperature during warm days.

But what is the right setting, exactly? We review suggestions from energy professionals so you can determine the best setting for your loved ones.

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

Recommended Thermostat Settings for Summer

Most families find using the thermostat at 72-73 degrees is ideal. However, if there’s a sizeable difference between your inside and outdoor temperatures, your AC costs will be bigger.

These are our recommendations based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that sounds too high, there are ways you can keep your house refreshing without having the air conditioner running all the time.

Keeping windows and window treatments closed during the day keeps cool air where it needs to be—indoors. Some window coverings, such as honeycomb shades or plantation shutters, are created to provide more insulation and better energy efficiency.

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

If 78 degrees still appears too hot on the surface, try conducting a test for a week or so. Get started by increasing your setting to 78 degrees while you’re at your residence. Then, steadily decrease it while using the advice above. You might be surprised at how cool you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the AC running all day while your home is vacant. Moving the temperature 7¬¬–10 degrees higher can save you as much as 5–15% on your air conditioning expenses, according to the DOE.

When you get home, don’t be tempted to set your thermostat under 78 to cool your house faster. This isn’t productive and often results in a higher AC bills.

A programmable thermostat is a good way to keep your temperature under control, but you have to set programs. If you don’t use programs, you might forget to move the set temperature when you go.

If you want a convenient resolution, consider getting a smart thermostat. This thermostat links with your phone, so it realizes when you’re at your residence and when you’re away. Then it instinctively modifies temperature settings for the best savings. How much exactly? An estimated $180 yearly on heating and cooling, according to ENERGY STAR.

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

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that might be unpleasant for most families. Many people sleep better when their bedroom is chilled, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that might be too cold, depending on your PJ and blanket preference.

We suggest trying a comparable test over a week, setting your temperature higher and progressively lowering it to find the best setting for your house. On pleasant nights, you might learn keeping windows open at night and relying on a ceiling fan is a superior solution than operating the air conditioning.

More Ways to Save Energy During Warm Weather

There are other methods you can conserve money on cooling bills throughout hot weather.

  1. Buy an energy-efficient air conditioning system. Central air conditioners only last about 12–15 years and lose efficiency as they age. An upgraded air conditioner can keep your residence comfier while keeping electrical
  2. bills low.
  3. Set annual AC service. Annual air conditioner maintenance keeps your unit operating properly and might help it operate more efficiently. It can also help extend its life cycle, since it allows pros to find little problems before they lead to an expensive meltdown.
  4. Switch air filters frequently. Read manufacturer instructions for changing your air filter. A dusty filter can result in your system short cycling, or run too frequently, and raise your electricity
  5. costs.
  6. Inspect attic insulation levels. Just about 90% of residences in the USA don’t have adequate insulation, according to the Insulation Institute. The majority of southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork examined. Ductwork that has separated over the years can seep cold air into your attic, walls or crawl space. This can result in big comfort problems in your house, including hot and cold spots.
  8. Seal cracks, doors and windows. Keep hot air where it should be by sealing holes. You can also caulk or weather strip doors to seal more conditioned air inside.
