Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to sacrifice comfort or empty your wallet to keep your home at a refreshing temperature during muggy weather.

But what is the best temperature, exactly? We go over ideas 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 Columbia.

Recommended Thermostat Settings for Summer

Most families find using the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a major difference between your indoor and outside temperatures, your electricity costs will be larger.

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

While at home: 78 degrees. While that seems too high, there are approaches you can keep your residence cool without having the air conditioner going frequently.

Keeping windows and blinds down during the day keeps cold air where it belongs—indoors. Some window coverings, like honeycomb shades or plantation shutters, are made to give extra insulation and enhanced energy efficiency.

If you have ceiling fans in your home, the DOE says you can move thermostat temps about 4 degrees hotter without compromising comfort. That’s due to the fact they freshen with a windchill effect. Because they cool people, not areas, turn them off when you leave a room.

If 78 degrees still appears too uncomfortable initially, try conducting a trial for approximately a week. Start by raising your thermostat to 78 degrees while you’re at your residence. Then, progressively turn it down while following the tips above. You could be shocked at how cool you feel at a hotter temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioning running all day while your home is empty. Switching the temperature 7¬¬–10 degrees hotter can save you an estimated 5–15% on your AC costs, according to the DOE.

When you come home, don’t be tempted to switch your thermostat under 78 to cool your house faster. This isn’t effective and usually results in a more expensive electricity cost.

A programmable thermostat is a helpful way to keep your temp controlled, but you have to set programs. If you don’t utilize programs, you might forget to increase the set temperature when you take off.

If you want a handy remedy, consider buying a smart thermostat. This thermostat connects with your phone, so it is aware when you’re at home and when you’re gone. Then it automatically adjusts temperature settings for maximum savings. How much exactly? Typically $180 each year on heating and cooling, according to ENERGY STAR.

Another plus of getting a smart thermostat? You can use your phone to monitor and change temperature settings from almost anywhere.

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

We advise trying a similar test over a week, putting your temp higher and slowly decreasing it to select the ideal setting for your house. On pleasant nights, you may find keeping windows open at night and using a ceiling fan is a preferable option than running the AC.

More Ways to Conserve Energy During Hot Weather

There are added methods you can spend less money on air conditioning bills throughout the summer.

  1. Upgrade to an energy-efficient AC system. Central air conditioners only last about 12–15 years and become less efficient as they get older. A new air conditioner can keep your residence more comfortable while keeping energy
  2. bills down.
  3. Book annual air conditioner service. Routine air conditioner maintenance keeps your unit running properly and might help it run at better efficiency. It could also help extend its life expectancy, since it helps professionals to pinpoint seemingly insignificant troubles before they create a major meltdown.
  4. Change air filters frequently. Read manufacturer instructions for replacing your air filter. A dirty filter can cause your system to short cycle, or switch on and off too frequently, and raise your electrical
  5. bills.
  6. Inspect attic insulation levels. Almost 90% of homes in the USA 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 separated over time can seep conditioned air into your attic, walls or crawl space. This can result in big comfort issues in your home, including hot and cold spots.
  8. Seal openings, doors and windows. Keep warm air in its place by sealing cracks. You can also caulk or weather strip doors to trap more conditioned air indoors.
