Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to give up comfort or drain your wallet to keep your residence at a pleasant temperature during summer weather.

But what is the right setting, exactly? We discuss recommendations from energy specialists so you can select the best temperature for your home.

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

Recommended Thermostat Settings for Summer

Most families find setting the thermostat at 72-73 degrees is ideal. However, if there’s a major difference between your interior and exterior warmth, your AC costs will be greater.

This is our advice based on the U.S. Department of Energy (DOE) and ENERGY STAR®.

While at home: 78 degrees. While that seems hot, there are approaches you can keep your home pleasant without having the AC going all the time.

Keeping windows and window treatments down during the day keeps cool air where it should be—indoors. Some window solutions, including honeycomb shades or plantation shutters, are made to offer more insulation and improved energy efficiency.

If you have ceiling fans in your house, the DOE says you can increase thermostat temperatures about 4 degrees hotter without sacrificing comfort. That’s since they freshen through a windchill effect. Since they cool people, not spaces, shut them off when you leave a room.

If 78 degrees still feels too warm on the surface, try running an experiment for a week or so. Begin by raising your thermostat to 78 degrees while you’re home. Then, gradually turn it down while following the advice above. You may be astonished at how refreshed you feel at a hotter temperature setting.

While away: 88 degrees. There’s no need to keep the AC running all day while your house is empty. Moving the setting 7¬¬–10 degrees hotter can save you as much as 5–15% on your air conditioning bills, according to the DOE.

When you get home, don’t be tempted to put your thermostat below 78 to cool your residence more rapidly. This isn’t productive and typically leads to a bigger AC cost.

A programmable thermostat is a helpful approach to keep your settings in check, but you have to set programs. If you don’t use programs, you might forget to move the set temperature when you go.

If you want a handy solution, think over buying 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 changes temperature settings for maximum savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

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

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that could be unpleasant for most families. Many people sleep better when their sleeping area is chilly, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that may be too chilly, depending on your pajama and blanket preference.

We recommend using a similar test over a week, putting your thermostat higher and gradually turning it down to determine the best temperature for your residence. On cool nights, you might learn keeping windows open at night and relying on a ceiling fan is a superior solution than using the air conditioning.

More Methods to Conserve Energy This Summer

There are extra methods you can conserve money on air conditioning bills throughout warm weather.

  1. Get an energy-efficient cooling system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they become older. A new air conditioner can keep your house cooler while keeping electrical
  2. expenses down.
  3. Book regular AC service. Annual air conditioner maintenance keeps your system running properly and might help it work more efficiently. It could also help prolong its life cycle, since it enables technicians to pinpoint little troubles before they cause a major meltdown.
  4. Replace air filters regularly. Use manufacturer instructions for changing your air filter. A clogged filter can cause your system to short cycle, or turn on and off too much, and drive up your electricity
  5. costs.
  6. Check attic insulation levels. Almost 90% of residences in the U.S. don’t have enough insulation, according to the Insulation Institute. Many southern climates require 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork inspected. Ductwork that has separated as it’s aged can seep cold air into your attic, walls or crawl space. This can create big comfort troubles in your home, such as hot and cold spots.
  8. Seal holes, doors and windows. Keep muggy air in its place by closing holes. You can also caulk or weather strip doors to keep more conditioned air within your home.
