Whats the Most Energy-Efficient AC Setting?

You shouldn’t be forced to compromise on comfort or drain your wallet to keep your home at the right temperature during hot days.

But what is the best temp, exactly? We discuss suggestions from energy experts so you can choose the best temperature for your home.

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

Recommended Thermostat Settings for Summer

Most people find placing the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your inside and exterior temps, your cooling bills will be higher.

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

While at home: 78 degrees. While that seems hot, there are approaches you can keep your house cool without having the AC running all the time.

Keeping windows and window treatments shut during the day keeps cold air where it should be—within your home. Some window treatments, like honeycomb shades or plantation shutters, are designed to deliver added insulation and enhanced energy conservation.

If you have ceiling fans in your home, the DOE says you can raise thermostat temperatures about 4 degrees higher without giving up comfort. That’s since they cool by a windchill effect. As they cool people, not rooms, switch them off when you leave a room.

If 78 degrees still feels too hot initially, try running a trial for about a week. Start by raising your setting to 78 degrees while you’re at your residence. Then, steadily lower it while adhering to the ideas above. You could be shocked at how cool you feel at a warmer temperature setting.

While away: 88 degrees. There’s no rationale for keeping the air conditioning going all day while your house is vacant. Switching the temperature 7¬¬–10 degrees higher can save you as much as 5–15% on your electricity bills, according to the DOE.

When you get home, don’t be tempted to switch your thermostat colder than 78 to cool your home faster. This isn’t useful and often leads to a bigger electrical cost.

A programmable thermostat is a useful approach to keep your settings under control, but you have to set programs. If you don’t utilize programs, you run the risk of forgetting to raise the set temperature when you leave.

If you’re looking for a handy remedy, think over installing a smart thermostat. This thermostat works with with your phone, so it realizes when you’re at home and when you’re out. Then it intuitively adjusts temperature settings for maximum savings. How much exactly? Usually $180 each year on heating and cooling, according to ENERGY STAR.

Another benefit of having a smart thermostat? You can use your phone to watch and adjust temperature settings from almost anywhere.

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

We recommend trying a similar test over a week, moving your temperature higher and gradually decreasing it to pick the right temp for your family. On cool nights, you could learn keeping windows open at night and relying on a ceiling fan is a preferable idea than using the air conditioner.

More Approaches to Conserve Energy During Warm Weather

There are additional approaches you can spend less money on AC bills throughout hot weather.

  1. Buy an energy-efficient AC system. Central air conditioners only work for about 12–15 years and become less efficient as they become older. An updated air conditioner can keep your house cooler while keeping cooling
  2. bills down.
  3. Book regular air conditioning maintenance. Annual air conditioner maintenance keeps your unit operating properly and could help it run more efficiently. It might also help extend its life span, since it allows pros to discover little troubles before they create an expensive meltdown.
  4. Change air filters often. Read manufacturer instructions for replacing your air filter. A clogged filter can lead to your system short cycling, or run too much, and raise your energy
  5. costs.
  6. Measure attic insulation levels. Just about 90% of houses in the USA don’t have adequate insulation, according to the Insulation Institute. Many southern climates should have 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork checked. Ductwork that has loosened over the years can seep cool air into your attic, walls or crawl space. This can create major comfort problems in your house, such as hot and cold spots.
  8. Seal openings, doors and windows. Keep muggy air in its place by sealing holes. You can also caulk or weather strip doors to trap more cool air indoors.
