Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to sacrifice comfort or drain your wallet to keep your house at a pleasant setting during hot days.

But what is the best setting, exactly? We review recommendations from energy professionals so you can choose the best temp for your home.

Here’s what we recommend for the most energy-efficient setting for air conditioning in Kutztown and Breinigsville.

Recommended Thermostat Settings for Summer

Most people find using the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a major difference between your indoor and outside temps, your cooling 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 warm, there are methods you can keep your residence cool without having the AC on all the time.

Keeping windows and curtains shut during the day keeps cold air where it needs to be—indoors. Some window coverings, like honeycomb shades or plantation shutters, are created to provide added insulation and better energy conservation.

If you have ceiling fans in your home, the DOE says you can increase thermostat temps about 4 degrees higher without compromising comfort. That’s due to the fact they refresh with a windchill effect. Because they cool people, not spaces, shut them off when you exit a room.

If 78 degrees still feels too warm at first glance, try running a trial for a week or so. Get started by raising your thermostat to 78 degrees while you’re home. Then, gradually decrease it while adhering to the advice above. You may be shocked at how cool you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioning on all day while your house is vacant. Moving the temp 7¬¬–10 degrees warmer can save you anywhere from 5–15% on your electrical bills, according to the DOE.

When you get home, don’t be tempted to switch your thermostat below 78 to cool your home more rapidly. This isn’t useful and typically produces a more expensive AC expense.

A programmable thermostat is a useful method to keep your temp in check, but it requires setting programs. If you don’t set programs, you might forget to increase the set temperature when you take off.

If you need a handy solution, consider getting a smart thermostat. This thermostat links with your phone, so it knows when you’re at your residence and when you’re gone. Then it intuitively changes temperature settings for the biggest savings. How much exactly? Usually $180 yearly on heating and cooling, according to ENERGY STAR.

Another benefit of having 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 recommends 82 degrees, that might be unbearable for most families. The majority of people sleep better when their sleeping area is chilled, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that could be too chilly, based on your clothing and blanket preference.

We recommend using an equivalent test over a week, putting your thermostat higher and progressively turning it down to select the right setting 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 operating the air conditioning.

More Approaches to Conserve Energy During Hot Weather

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

  1. Get an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and become less efficient as they get older. An upgraded air conditioner can keep your home cooler while keeping utility
  2. bills small.
  3. Book annual air conditioning tune-ups. Routine air conditioner maintenance keeps your unit running like it should and could help it work at greater efficiency. It may also help prolong its life expectancy, since it helps pros to discover little problems before they cause a big meltdown.
  4. Change air filters often. Use manufacturer instructions for changing your air filter. A clogged filter can cause your system to short cycle, or switch on and off too much, and drive up your electrical
  5. costs.
  6. Check attic insulation levels. Just about 90% of residences in the USA don’t have proper insulation, according to the Insulation Institute. Most southern climates should have 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork examined. Ductwork that has separated over time can leak cold air into your attic, walls or crawl space. This can create major comfort problems in your home, including hot and cold spots.
  8. Seal holes, doors and windows. Keep warm air in its place by plugging holes. You can also caulk or weather strip doors to keep more cool air inside.
