Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to give up comfort or empty your wallet to keep your house at a refreshing temperature during the summer.

But what is the best temperature, exactly? We discuss recommendations from energy professionals so you can choose the best setting for your loved ones.

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees is ideal. However, if there’s a huge difference between your interior and outdoor warmth, your cooling expenses 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 warm, there are approaches you can keep your house cool without having the air conditioner on constantly.

Keeping windows and window treatments shut during the day keeps cool air where it belongs—inside. Some window solutions, including honeycomb shades or plantation shutters, are designed to offer added insulation and better energy conservation.

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

If 78 degrees still seems too hot at first glance, try running a test for a week or so. Get started by upping your setting to 78 degrees while you’re home. Then, gradually decrease it while following the tips above. You could be amazed at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the AC working all day while your residence is unoccupied. Switching the setting 7¬¬–10 degrees higher can save you as much as 5–15% on your air conditioning bills, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat below 78 to cool your home faster. This isn’t useful and usually produces a more expensive electricity cost.

A programmable thermostat is a helpful approach to keep your settings controlled, but you have to set programs. If you don’t use programs, you risk forgetting to raise the set temperature when you go.

If you’re looking for a hassle-free remedy, think over installing a smart thermostat. This thermostat connects with your phone, so it is aware 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 annually on heating and cooling, according to ENERGY STAR.

Another advantage of using a smart thermostat? You can use your phone to keep an eye on and change temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that could be unbearable for the majority of families. Many people sleep better when their bedroom is chilled, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that may be too cool, due to your pajama and blanket preference.

We advise following a similar test over a week, moving your temperature higher and slowly lowering it to determine the right temp for your residence. On cool nights, you might learn keeping windows open at night and relying on a ceiling fan is a superior option than operating the AC.

More Methods to Save Energy During Hot Weather

There are other methods you can save money on air conditioning bills throughout warm weather.

  1. Buy an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and get less efficient as they get older. An upgraded air conditioner can keep your residence more comfortable while keeping utility
  2. bills low.
  3. Set yearly air conditioner tune-ups. Annual air conditioner maintenance keeps your system working properly and may help it work at better efficiency. It might also help extend its life expectancy, since it enables techs to uncover small problems before they create a big meltdown.
  4. Change air filters frequently. Follow manufacturer instructions for replacing your air filter. A clogged filter can result in your system short cycling, or switch on and off too often, and raise your cooling
  5. expenses.
  6. Measure attic insulation levels. Just about 90% of houses in the USA don’t have enough insulation, according to the Insulation Institute. Most southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork examined. Ductwork that has loosened over time can seep conditioned 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 cracks, doors and windows. Keep warm air where it should be by sealing cracks. You can also caulk or weather strip doors to keep more conditioned air indoors.
