Whats the Most Energy-Efficient AC Setting?

June 04, 2020

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

But what is the ideal temperature, exactly? We go over ideas from energy professionals so you can choose the best setting for your house.

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

Recommended Thermostat Settings for Summer

Most people find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your indoor and exterior warmth, your electrical bills will be greater.

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 home pleasant without having the air conditioner running all the time.

Keeping windows and window treatments shut during the day keeps chilled air where it needs to be—indoors. Some window solutions, like honeycomb shades or plantation shutters, are created to deliver more insulation and improved energy conservation.

If you have ceiling fans in your residence, the DOE says you can raise thermostat temps about 4 degrees hotter without sacrificing comfort. That’s because they cool by a windchill effect. Since they cool people, not areas, turn them off when you leave a room.

If 78 degrees still feels too uncomfortable at first glance, try doing a test for approximately a week. Begin by increasing your thermostat to 78 degrees while you’re home. Then, steadily turn it down while adhering to the ideas above. You could be surprised at how cool you feel at a warmer temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner working all day while your house is unoccupied. Moving the setting 7¬¬–10 degrees higher can save you an estimated 5–15% on your electricity costs, according to the DOE.

When you get home, don’t be tempted to switch your thermostat below 78 to cool your residence faster. This isn’t effective and often leads to a more expensive electrical bills.

A programmable thermostat is a useful way to keep your temp in check, but you have to set programs. If you don’t use programs, you run the risk of forgetting to change the set temperature when you take off.

If you need a handy solution, consider buying a smart thermostat. This thermostat links with your phone, so it knows when you’re at your house and when you’re gone. Then it automatically modifies temperature settings for the biggest savings. How much exactly? An estimated $180 each year on heating and cooling, according to ENERGY STAR.

Another advantage of installing a smart thermostat? You can use your phone to keep an eye on and regulate temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that could be unbearable for the majority of families. The majority of people sleep better when their sleeping space is chilly, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that may be too cold, depending on your PJ and blanket preference.

We recommend using a comparable test over a week, moving your temp higher and progressively decreasing it to pinpoint the ideal setting for your family. On cool nights, you may find keeping windows open at night and running a ceiling fan is a preferable option than using the AC.

More Approaches to Save Energy During Hot Weather

There are added ways you can conserve money on air conditioning bills throughout warm weather.

  1. Buy an energy-efficient AC system. Central air conditioners only last about 12–15 years and get less efficient as they age. A new air conditioner can keep your home cooler while keeping utility
  2. bills down.
  3. Schedule regular AC service. Regular air conditioner maintenance keeps your system operating smoothly and could help it work more efficiently. It may also help lengthen its life expectancy, since it enables technicians to find small issues before they lead to an expensive meltdown.
  4. Change air filters often. Use manufacturer instructions for switching your air filter. A clogged filter can result in your system short cycling, or run too much, and raise your electricity
  5. expenses.
  6. Measure attic insulation levels. Almost 90% of homes in the U.S. don’t have proper insulation, according to the Insulation Institute. Most southern climates need 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork inspected. Ductwork that has loosened as it’s aged can leak conditioned air into your attic, walls or crawl space. This can lead to big comfort problems in your house, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep hot air in its place by plugging holes. You can also caulk or weather strip doors to trap more cool air inside.
