Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t have to give up comfort or spend a lot to keep your home at the right setting during the summer.

But what is the right temperature, exactly? We discuss recommendations from energy specialists so you can determine the best setting for your family.

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

Recommended Thermostat Settings for Summer

Most families find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your inside and outdoor temperatures, your electricity bills will be greater.

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

While at home: 78 degrees. While that appears too high, there are ways you can keep your house refreshing without having the air conditioning on all the time.

Keeping windows and blinds shut during the day keeps cool air where it should be—inside. Some window solutions, such as honeycomb shades or plantation shutters, are created to provide added insulation and enhanced energy savings.

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

If 78 degrees still seems too warm on the surface, try running an experiment for a week or so. Get started by increasing your temperature to 78 degrees while you’re at your house. Then, gradually lower it while adhering to the tips above. You could be astonished at how comfortable you feel at a warmer temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioner on all day while your house is empty. Moving the temp 7¬¬–10 degrees higher can save you as much as 5–15% on your AC costs, according to the DOE.

When you get home, don’t be tempted to set your thermostat under 78 to cool your house faster. This isn’t productive and often leads to a higher cooling bills.

A programmable thermostat is a useful method to keep your settings under control, but you have to set programs. If you don’t set programs, you might forget to raise the set temperature when you take off.

If you need a handy resolution, think over installing a smart thermostat. This thermostat connects with your phone, so it is aware when you’re at your residence and when you’re out. Then it intuitively modifies temperature settings for the biggest savings. How much exactly? Typically $180 annually on heating and cooling, according to ENERGY STAR.

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

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

We suggest running a similar test over a week, setting your temperature higher and gradually lowering it to determine the ideal temp for your house. On cool nights, you may find keeping windows open at night and using a ceiling fan is a better option than running the air conditioning.

More Approaches to Use Less Energy During Hot Weather

There are other approaches you can conserve money on utility bills throughout the summer.

  1. Get an energy-efficient air conditioning system. Central air conditioners only last about 12–15 years and get less efficient as they get older. A new air conditioner can keep your house comfier while keeping energy
  2. bills low.
  3. Book yearly air conditioning maintenance. Regular air conditioner maintenance keeps your equipment running like it should and might help it work at greater efficiency. It might also help extend its life expectancy, since it enables professionals to discover small troubles before they lead to an expensive meltdown.
  4. Put in new air filters regularly. Read manufacturer instructions for changing your air filter. A dirty filter can cause your system to short cycle, or turn on and off too much, and increase your utility
  5. expenses.
  6. Check attic insulation levels. Just about 90% of homes in the U.S. don’t have enough insulation, according to the Insulation Institute. Many southern climates need 13–14” of attic insulation, while northern climates should have 16–18”.
  7. Have your ductwork inspected. Ductwork that has come apart over the years can seep cool air into your attic, walls or crawl space. This can result in big comfort problems in your house, including hot and cold spots.
  8. Seal cracks, doors and windows. Keep hot air in its place by closing cracks. You can also caulk or weather strip doors to trap more cold air indoors.
