Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or empty your wallet to keep your residence at a refreshing temp during muggy weather.

But what is the right temperature, exactly? We discuss advice from energy pros so you can select the best temp for your loved ones.

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

Recommended Thermostat Settings for Summer

Most families find placing the thermostat at 72-73 degrees is ideal. However, if there’s a sizeable difference between your indoor and outdoor temperatures, your cooling 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 too high, there are ways you can keep your house refreshing without having the air conditioner on all the time.

Keeping windows and blinds shut during the day keeps cold air where it belongs—inside. Some window solutions, like honeycomb shades or plantation shutters, are designed to offer more insulation and enhanced energy savings.

If you have ceiling fans in your house, the DOE says you can raise thermostat temps about 4 degrees higher without sacrificing comfort. That’s because they freshen with a windchill effect. As they cool people, not areas, shut them off when you leave a room.

If 78 degrees still feels too warm on the surface, try running a test for about a week. Start by increasing your thermostat to 78 degrees while you’re home. Then, steadily decrease it while following the advice above. You might be surprised at how refreshed you feel at a hotter temperature setting.

While away: 88 degrees. There’s no need to keep the AC going all day while your residence is unoccupied. Switching the temperature 7¬¬–10 degrees warmer can save you as much as 5–15% on your electricity costs, according to the DOE.

When you arrive home, don’t be tempted to switch your thermostat below 78 to cool your residence faster. This isn’t useful and usually produces a more expensive electrical bills.

A programmable thermostat is a useful approach to keep your temp controlled, but you have to set programs. If you don’t use programs, you might forget to change the set temperature when you leave.

If you need a handy resolution, think about getting a smart thermostat. This thermostat connects with your phone, so it realizes when you’re at your residence and when you’re out. Then it intuitively adjusts temperature settings for maximum savings. How much exactly? An estimated $180 annually on heating and cooling, according to ENERGY STAR.

Another plus of installing a smart thermostat? You can use your phone to monitor and change temperature settings from nearly anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR suggests 82 degrees, that may be unbearable for the majority of families. Most people sleep better when their bedroom is chilly, so that’s why the National Sleep Foundation recommends 60–67 degrees. But that might be too cold, due to your PJ and blanket preference.

We recommend following a comparable test over a week, setting your temperature higher and progressively turning it down to pinpoint the right temp for your family. On mild nights, you may find keeping windows open at night and running a ceiling fan is a preferable solution than running the AC.

More Methods to Save Energy This Summer

There are other ways you can spend less money on AC bills throughout warm weather.

  1. Get an energy-efficient air conditioning system. Central air conditioners only are effective for about 12–15 years and get less efficient as they become older. An updated air conditioner can keep your house more comfortable while keeping cooling
  2. costs small.
  3. Book regular air conditioner maintenance. Regular air conditioner maintenance keeps your unit running properly and might help it run at greater efficiency. It could also help lengthen its life span, since it allows pros to discover little issues before they create a major meltdown.
  4. Change air filters often. Read manufacturer instructions for switching your air filter. A clogged filter can cause your system to short cycle, or turn on and off too frequently, 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. The majority of southern climates should have 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork examined. Ductwork that has loosened over the years can seep cold air into your attic, walls or crawl space. This can create major comfort problems in your home, like hot and cold spots.
  8. Seal openings, doors and windows. Keep warm air in its place by closing cracks. You can also caulk or weather strip doors to trap more conditioned air indoors.
