Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to compromise on comfort or drain your wallet to keep your home at a refreshing temperature during hot days.

But what is the best setting, exactly? We review recommendations from energy pros so you can choose the best temperature for your residence.

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

Recommended Thermostat Settings for Summer

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

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

While at home: 78 degrees. While that seems too high, there are ways you can keep your home pleasant without having the AC running constantly.

Keeping windows and blinds closed during the day keeps cold air where it belongs—inside. Some window coverings, including honeycomb shades or plantation shutters, are made to offer more insulation and better energy efficiency.

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

If 78 degrees still feels too uncomfortable on the surface, try conducting a test for approximately a week. Get started by upping your temperature to 78 degrees while you’re at your house. Then, progressively turn it down while using the tips above. You could be amazed at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no need to keep the AC working all day while your home is unoccupied. Moving the setting 7¬¬–10 degrees warmer can save you as much as 5–15% on your cooling costs, according to the DOE.

When you get home, don’t be tempted to switch your thermostat colder than 78 to cool your house more quickly. This isn’t effective and usually leads to a more expensive electricity bills.

A programmable thermostat is a good method to keep your settings in check, but you need to set programs. If you don’t use programs, you run the risk of forgetting to move the set temperature when you leave.

If you need a hassle-free remedy, consider installing a smart thermostat. This thermostat connects with your phone, so it knows when you’re at home and when you’re out. Then it intuitively modifies temperature settings for maximum savings. How much exactly? An estimated $180 each year on heating and cooling, according to ENERGY STAR.

Another perk of using a smart thermostat? You can use your phone to monitor and adjust temperature settings from almost anywhere.

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

We suggest following a comparable test over a week, putting your thermostat higher and steadily lowering it to find the right temp for your house. On pleasant nights, you might learn keeping windows open at night and running a ceiling fan is a better solution than using the AC.

More Methods to Save Energy During Warm Weather

There are extra methods you can save money on utility bills throughout hot weather.

  1. Upgrade to an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and lose efficiency as they become older. An updated air conditioner can keep your house cooler while keeping electricity

  3. Book regular air conditioner tune-ups. Regular air conditioner maintenance keeps your system operating smoothly and might help it run at greater efficiency. It might also help extend its life cycle, since it enables technicians to find little problems before they cause a big meltdown.
  4. Switch air filters often. Follow manufacturer instructions for replacing your air filter. A clogged filter can result in your system short cycling, or turn on and off too much, and increase your energy
  5. costs.
  6. Measure attic insulation levels. Almost 90% of residences in the U.S. don’t have adequate insulation, according to the Insulation Institute. Most southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork checked. Ductwork that has come apart over time can leak cold air into your attic, walls or crawl space. This can lead to big comfort troubles in your home, including hot and cold spots.
  8. Seal holes, doors and windows. Keep humid air where it should be by plugging openings. You can also caulk or weather strip doors to keep more cool air within your home.
