Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or drain your wallet to keep your house at a pleasant temp during summer weather.

But what is the ideal setting, exactly? We go over advice from energy experts so you can select the best temp for your house.

Here’s what we suggest for the most energy-efficient setting for air conditioning in Paso Robles.

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a sizeable difference between your interior and exterior temperatures, your AC bills will be higher.

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

While at home: 78 degrees. While that sounds hot, there are approaches you can keep your home cool without having the AC going constantly.

Keeping windows and window treatments closed during the day keeps cool air where it belongs—indoors. Some window coverings, including honeycomb shades or plantation shutters, are designed to provide added insulation and better energy efficiency.

If you have ceiling fans in your house, the DOE says you can increase thermostat settings about 4 degrees hotter without compromising comfort. That’s due to the fact they cool through a windchill effect. As they cool people, not areas, turn them off when you leave a room.

If 78 degrees still seems too hot on the surface, try running a test for approximately a week. Start by increasing your thermostat to 78 degrees while you’re home. Then, gradually turn it down while following the suggestions above. You might be amazed at how refreshed you feel at a hotter temperature setting.

While away: 88 degrees. There’s no reason to keep the air conditioner working all day while your residence is empty. Moving the temperature 7¬¬–10 degrees warmer can save you as much as 5–15% on your AC expenses, according to the DOE.

When you come home, don’t be tempted to put your thermostat under 78 to cool your home faster. This isn’t useful and usually results in a more expensive air conditioner bills.

A programmable thermostat is a good approach to keep your settings in check, but it requires setting programs. If you don’t use programs, you might forget to increase the set temperature when you leave.

If you want a hassle-free resolution, consider getting a smart thermostat. This thermostat works with with your phone, so it realizes when you’re at home and when you’re out. Then it automatically adjusts temperature settings for maximum savings. How much exactly? Typically $180 annually on heating and cooling, according to ENERGY STAR.

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

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that might be too uncomfortable for the majority of families. Many people sleep better when their sleeping area is chilly, so that’s why the National Sleep Foundation advises 60–67 degrees. But that might be too chilly, due to your clothing and blanket preference.

We recommend running a comparable test over a week, moving your temp higher and gradually decreasing it to determine the right temp for your family. On pleasant nights, you might find keeping windows open at night and relying on a ceiling fan is a preferable option than using the air conditioner.

More Ways to Save Energy This Summer

There are extra ways you can save money on energy bills throughout warm weather.

  1. Install an energy-efficient air conditioning system. Central air conditioners only work for about 12–15 years and become less efficient as they age. An updated air conditioner can keep your residence cooler while keeping AC
  2. bills low.
  3. Schedule regular air conditioning service. Routine air conditioner maintenance keeps your unit running smoothly and may help it run at greater efficiency. It might also help prolong its life span, since it helps technicians to find little troubles before they cause a major meltdown.
  4. Replace air filters frequently. Read manufacturer instructions for replacing your air filter. A clogged filter can lead to your system short cycling, or switch on and off too much, and increase your cooling
  5. bills.
  6. Measure attic insulation levels. Almost 90% of homes in the United States don’t have enough 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 checked. Ductwork that has come apart as it’s aged can let cold air into your attic, walls or crawl space. This can lead to huge comfort troubles in your house, like hot and cold spots.
  8. Seal holes, doors and windows. Keep muggy air where it belongs by plugging holes. You can also caulk or weather strip doors to trap more cool air inside.
