Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t be forced to sacrifice comfort or spend a lot to keep your house at a refreshing temp during hot days.

But what is the best temperature, exactly? We review advice from energy professionals so you can find the best temperature for your house.

Here’s what we recommend for the most energy-efficient setting for air conditioning in Port St. Lucie.

Recommended Thermostat Settings for Summer

Most people find setting the thermostat at 72-73 degrees is most comfortable. However, if there’s a major difference between your interior and exterior temps, your electrical costs 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 seems too high, there are approaches you can keep your residence pleasant without having the air conditioning running all the time.

Keeping windows and blinds closed during the day keeps cool air where it needs to be—within your home. Some window coverings, such as honeycomb shades or plantation shutters, are created to provide more insulation and improved energy savings.

If you have ceiling fans in your house, the DOE says you can move thermostat temps about 4 degrees higher without giving up comfort. That’s due to the fact they cool through a windchill effect. Because they cool people, not areas, turn them off when you move from a room.

If 78 degrees still appears too warm initially, try conducting a trial for a week or so. Start by increasing your temperature to 78 degrees while you’re at your house. Then, gradually decrease it while using the advice above. You could be amazed at how cool you feel at a higher temperature setting.

While away: 88 degrees. There’s no rationale for keeping the AC working all day while your house is unoccupied. Turning the temp 7¬¬–10 degrees higher can save you anywhere from 5–15% on your electrical expenses, according to the DOE.

When you come home, don’t be tempted to set your thermostat below 78 to cool your house more rapidly. This isn’t effective and typically produces a more expensive air conditioner expense.

A programmable thermostat is a useful approach to keep your settings controlled, but it requires setting programs. If you don’t utilize programs, you risk forgetting to increase the set temperature when you take off.

If you need a convenient fix, think about getting a smart thermostat. This thermostat connects with your phone, so it realizes when you’re at your house and when you’re out. Then it automatically changes temperature settings for the best savings. How much exactly? Typically $180 yearly on heating and cooling, according to ENERGY STAR.

Another advantage of getting a smart thermostat? You can use your phone to monitor and regulate temperature settings from almost anywhere.

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

We advise running an equivalent test over a week, moving your temp higher and steadily decreasing it to pick the best temp for your family. On mild nights, you may discover keeping windows open at night and running a ceiling fan is a superior solution than running the air conditioning.

More Ways to Use Less Energy During Hot Weather

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

  1. Get an energy-efficient cooling system. Central air conditioners only last about 12–15 years and lose efficiency as they age. A new air conditioner can keep your residence more comfortable while keeping cooling
  2. bills small.
  3. Set yearly air conditioner maintenance. Routine air conditioner maintenance keeps your system running properly and might help it operate at better efficiency. It may also help prolong its life cycle, since it allows technicians to uncover seemingly insignificant issues before they lead to a big meltdown.
  4. Change air filters regularly. Use manufacturer instructions for replacing your air filter. A dusty filter can cause your system to short cycle, or switch on and off too often, and drive up your cooling
  5. bills.
  6. Measure attic insulation levels. Nearly 90% of residences in the USA don’t have enough insulation, according to the Insulation Institute. Many southern climates should have 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork inspected. Ductwork that has come apart over time can let conditioned air into your attic, walls or crawl space. This can lead to major comfort issues in your residence, like hot and cold spots.
  8. Seal cracks, doors and windows. Keep warm air where it belongs by closing openings. You can also caulk or weather strip doors to trap more conditioned air inside.
