Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to sacrifice comfort or spend a lot to keep your residence at a pleasant setting during summer weather.

But what is the right temp, exactly? We review ideas from energy experts so you can select the best setting for your home.

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a huge difference between your interior and outdoor warmth, your electricity expenses will be larger.

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

While at home: 78 degrees. While that appears hot, there are methods you can keep your home refreshing without having the air conditioner running constantly.

Keeping windows and blinds down during the day keeps cool air where it belongs—within your home. Some window treatments, such as honeycomb shades or plantation shutters, are created to offer more insulation and better energy savings.

If you have ceiling fans in your residence, the DOE says you can raise thermostat temperatures about 4 degrees hotter without giving up comfort. That’s since they refresh through a windchill effect. Since they cool people, not areas, shut them off when you leave a room.

If 78 degrees still seems too warm on the surface, try running a test for a week or so. Start by upping your temperature to 78 degrees while you’re at your house. Then, gradually lower it while adhering to the suggestions above. You might be surprised at how refreshed you feel at a higher temperature setting.

While away: 88 degrees. There’s no rationale for keeping the air conditioner running all day while your home is empty. Moving the temperature 7¬¬–10 degrees warmer can save you anywhere from 5–15% on your electricity costs, according to the DOE.

When you arrive home, don’t be tempted to set your thermostat colder than 78 to cool your house more quickly. This isn’t useful and typically leads to a more expensive air conditioner cost.

A programmable thermostat is a good approach to keep your settings in check, but you need to set programs. If you don’t use programs, you risk forgetting to raise the set temperature when you take off.

If you’re looking for a handy solution, consider installing a smart thermostat. This thermostat links with your phone, so it knows when you’re at your house and when you’re out. Then it instinctively modifies temperature settings for the best savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

Another benefit of installing 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 may be unbearable for most families. The majority of people sleep better when their sleeping space is cold, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that could be too chilly, depending on your PJ and blanket preference.

We advise using an equivalent test over a week, setting your temp higher and slowly lowering it to select the right temperature for your house. On cool nights, you could learn keeping windows open at night and relying on a ceiling fan is a better option than operating the air conditioning.

More Ways to Conserve Energy During Hot Weather

There are other methods you can save money on utility bills throughout the summer.

  1. Get an energy-efficient air conditioning system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they get older. An upgraded air conditioner can keep your residence cooler while keeping electrical
  2. bills down.
  3. Set yearly AC service. Regular air conditioner maintenance keeps your equipment operating properly and may help it operate at greater efficiency. It might also help lengthen its life expectancy, since it allows technicians to uncover seemingly insignificant problems before they cause a major meltdown.
  4. Put in new air filters regularly. Use manufacturer instructions for changing your air filter. A clogged filter can lead to your system short cycling, or turn on and off too much, and raise your electrical
  5. costs.
  6. Inspect attic insulation levels. Almost 90% of homes in the USA don’t have proper insulation, according to the Insulation Institute. Many southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork checked. Ductwork that has loosened as it’s aged can let conditioned air into your attic, walls or crawl space. This can result in huge comfort troubles in your residence, such as hot and cold spots.
  8. Seal openings, doors and windows. Keep muggy air where it should be by closing cracks. You can also caulk or weather strip doors to keep more cold air within your home.
