Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to give up comfort or drain your wallet to keep your home at a pleasant temp during hot days.

But what is the ideal setting, exactly? We discuss ideas from energy professionals so you can select the best temperature for your family.

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

Recommended Thermostat Settings for Summer

Most families find setting the thermostat at 72-73 degrees is most comfortable. However, if there’s a major difference between your inside and outside warmth, your electricity bills 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 sounds hot, there are methods you can keep your home pleasant without having the air conditioning running frequently.

Keeping windows and blinds shut during the day keeps cold air where it should be—within your home. Some window coverings, including honeycomb shades or plantation shutters, are made to provide more insulation and better energy efficiency.

If you have ceiling fans in your residence, the DOE says you can move thermostat temps about 4 degrees hotter without sacrificing comfort. That’s due to the fact they refresh through a windchill effect. As they cool people, not rooms, turn them off when you move from a room.

If 78 degrees still feels too warm at first glance, try doing a test for a week or so. Begin by upping your setting to 78 degrees while you’re at your residence. Then, progressively decrease it while using the tips above. You may be shocked at how cool you feel at a warmer temperature setting.

While away: 88 degrees. There’s no rationale for keeping the AC working all day while your residence is unoccupied. Moving the temp 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 set your thermostat under 78 to cool your residence more quickly. This isn’t productive and typically produces a higher electrical bills.

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

If you’re looking for a handy remedy, consider installing 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 instinctively modifies temperature settings for the best savings. How much exactly? About $180 annually on heating and cooling, according to ENERGY STAR.

Another advantage of using a smart thermostat? You can use your phone to keep an eye on and regulate temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR advises 82 degrees, that might be unbearable for the majority of families. Many people sleep better when their sleeping space is chilled, so that’s why the National Sleep Foundation advises 60–67 degrees. But that may be too chilly, depending on your pajama and blanket preference.

We recommend trying a similar test over a week, putting your temperature higher and gradually turning it down to determine the ideal temperature for your residence. On cool nights, you could discover keeping windows open at night and running a ceiling fan is a better option than running the AC.

More Ways to Conserve Energy During Hot Weather

There are additional approaches you can save money on utility bills throughout the summer.

  1. Get an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and get less efficient as they become older. An upgraded air conditioner can keep your home more comfortable while keeping energy
  2. bills low.
  3. Set yearly air conditioner maintenance. Routine air conditioner maintenance keeps your equipment operating like it should and might help it run at greater efficiency. It may also help lengthen its life expectancy, since it helps professionals to pinpoint little troubles before they create a big meltdown.
  4. Switch air filters often. Follow manufacturer instructions for replacing your air filter. A dusty filter can cause your system to short cycle, or run too often, and raise your electrical
  5. bills.
  6. Inspect attic insulation levels. Almost 90% of houses in the U.S. don’t have enough insulation, according to the Insulation Institute. Most southern climates should have 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork checked. Ductwork that has loosened over the years can let cool air into your attic, walls or crawl space. This can result in big comfort problems in your home, like hot and cold spots.
  8. Seal cracks, doors and windows. Keep muggy air where it should be by plugging cracks. You can also caulk or weather strip doors to trap more cold air within your home.
