Whats the Most Energy-Efficient AC Setting?

June 04, 2020

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

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

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

Recommended Thermostat Settings for Summer

Most households find setting the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a sizeable difference between your indoor and exterior warmth, your utility costs will be greater.

These are our recommendations 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 residence cool without having the air conditioner going constantly.

Keeping windows and window treatments closed during the day keeps chilled air where it should be—inside. Some window solutions, like honeycomb shades or plantation shutters, are created to give added insulation and enhanced energy efficiency.

If you have ceiling fans in your residence, the DOE says you can raise thermostat settings about 4 degrees warmer without compromising comfort. That’s because they cool through a windchill effect. Because they cool people, not areas, turn them off when you leave a room.

If 78 degrees still feels too hot at first glance, try conducting a trial for about a week. Begin by upping your temperature to 78 degrees while you’re at your house. Then, steadily lower it while adhering to the suggestions above. You might be surprised 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 vacant. Turning the temp 7¬¬–10 degrees warmer can save you an estimated 5–15% on your cooling expenses, 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 productive and often leads to a bigger air conditioner bills.

A programmable thermostat is a helpful method to keep your temperature controlled, but it requires setting programs. If you don’t utilize programs, you run the risk of forgetting to raise the set temperature when you go.

If you need a handy solution, consider getting a smart thermostat. This thermostat links with your phone, so it knows when you’re at your residence and when you’re gone. Then it automatically modifies temperature settings for the best savings. How much exactly? Usually $180 annually on heating and cooling, according to ENERGY STAR.

Another plus 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 suggests 82 degrees, that could be too uncomfortable for the majority of families. The majority of people sleep better when their sleeping space is cold, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that could be too cold, based on your pajama and blanket preference.

We recommend using a comparable test over a week, moving your temperature higher and gradually lowering it to locate the ideal temperature for your residence. On pleasant nights, you might find keeping windows open at night and relying on a ceiling fan is a better idea than running the air conditioning.

More Ways to Use Less Energy This Summer

There are extra ways you can spend less money on energy bills throughout warm weather.

  1. Get an energy-efficient cooling system. Central air conditioners only last about 12–15 years and lose efficiency as they get older. An upgraded air conditioner can keep your home comfier while keeping electricity
  2. bills low.
  3. Book annual AC tune-ups. Routine air conditioner maintenance keeps your unit running properly and might help it work more efficiently. It might also help lengthen its life expectancy, since it allows professionals to find seemingly insignificant issues before they lead to an expensive meltdown.
  4. Put in new air filters regularly. Follow manufacturer instructions for switching your air filter. A dusty filter can lead to your system short cycling, or run too frequently, and drive up your energy
  5. bills.
  6. Inspect attic insulation levels. Nearly 90% of residences in the USA don’t have enough insulation, according to the Insulation Institute. Many southern climates require 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork examined. Ductwork that has come apart over the years can let cold air into your attic, walls or crawl space. This can result in huge comfort issues in your residence, like hot and cold spots.
  8. Seal holes, doors and windows. Keep warm air where it belongs by sealing holes. You can also caulk or weather strip doors to trap more cool air indoors.
