Whats the Most Energy-Efficient AC Setting?

You shouldn’t be forced to give up comfort or spend a lot to keep your house at a refreshing temp during hot days.

But what is the right temperature, exactly? We review recommendations from energy experts so you can find the best temperature for your house.

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

Recommended Thermostat Settings for Summer

Most households find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a huge difference between your inside and exterior temperatures, your electrical costs will be bigger.

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

While at home: 78 degrees. While that sounds hot, there are ways you can keep your home cool without having the AC running frequently.

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

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

If 78 degrees still appears too uncomfortable on the surface, try running a test for about a week. Begin by increasing your thermostat to 78 degrees while you’re at your house. Then, steadily turn it down while adhering to the suggestions above. You might be astonished at how cool you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner going all day while your house is unoccupied. Switching the temperature 7¬¬–10 degrees hotter can save you as much as 5–15% on your electrical bills, according to the DOE.

When you come home, don’t be tempted to switch your thermostat colder than 78 to cool your house more quickly. This isn’t productive and usually results in a bigger AC bills.

A programmable thermostat is a helpful approach to keep your temp in check, but you have to set programs. If you don’t use programs, you might forget to move the set temperature when you leave.

If you want a handy solution, consider installing a smart thermostat. This thermostat works with with your phone, so it knows when you’re at your house and when you’re away. Then it intuitively modifies temperature settings for maximum savings. How much exactly? About $180 each year on heating and cooling, according to ENERGY STAR.

Another perk of getting 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 recommends 82 degrees, that might be unbearable for the majority of families. The majority of people sleep better when their sleeping space is chilled, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that may be too cold, based on your clothing and blanket preference.

We suggest trying a similar test over a week, setting your temp higher and progressively decreasing it to determine the best setting for your house. On cool nights, you could find keeping windows open at night and relying on a ceiling fan is a preferable option than operating the air conditioner.

More Methods to Use Less Energy During Hot Weather

There are additional ways you can save money on cooling bills throughout the summer.

  1. Install an energy-efficient AC 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 residence comfier while keeping AC
  2. bills small.
  3. Schedule annual AC service. Annual air conditioner maintenance keeps your unit running properly and could help it run at greater efficiency. It might also help extend its life span, since it allows professionals to find little troubles before they create an expensive meltdown.
  4. Put in new air filters often. Follow manufacturer instructions for switching your air filter. A dirty filter can lead to your system short cycling, or switch on and off too frequently, and raise your utility
  5. bills.
  6. Inspect attic insulation levels. Almost 90% of houses in the USA don’t have adequate insulation, according to the Insulation Institute. Most southern climates require 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork checked. Ductwork that has come apart as it’s aged can seep cold air into your attic, walls or crawl space. This can lead to big comfort problems in your home, including hot and cold spots.
  8. Seal holes, doors and windows. Keep humid air in its place by closing holes. You can also caulk or weather strip doors to seal more cool air indoors.
