Whats the Most Energy-Efficient AC Setting?

June 04, 2020

You shouldn’t need to sacrifice comfort or spend a lot to keep your home at a pleasant temp during warm days.

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

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

Recommended Thermostat Settings for Summer

Most households find using the thermostat at 72-73 degrees is most comfortable. However, if there’s a huge difference between your inside and outside 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 too high, there are ways you can keep your home cool without having the air conditioning running frequently.

Keeping windows and curtains shut during the day keeps cool air where it belongs—inside. Some window coverings, including honeycomb shades or plantation shutters, are created to offer extra insulation and enhanced energy efficiency.

If you have ceiling fans in your house, the DOE says you can move thermostat settings about 4 degrees higher without giving up comfort. That’s since they freshen through a windchill effect. Because they cool people, not rooms, shut them off when you leave a room.

If 78 degrees still feels too uncomfortable at first glance, try doing a trial for about a week. Get started by upping your temperature to 78 degrees while you’re home. Then, gradually turn it down while using the advice above. You could be amazed at how refreshed you feel at a warmer temperature setting.

While away: 88 degrees. There’s no need to keep the air conditioner working all day while your home is unoccupied. Turning the setting 7¬¬–10 degrees warmer can save you anywhere from 5–15% on your AC costs, according to the DOE.

When you arrive home, don’t be tempted to put your thermostat under 78 to cool your residence faster. This isn’t productive and typically leads to a higher electricity cost.

A programmable thermostat is a helpful way to keep your settings controlled, but you need to set programs. If you don’t set programs, you risk forgetting to change the set temperature when you go.

If you want a convenient fix, think about installing a smart thermostat. This thermostat works with with your phone, so it knows when you’re at home and when you’re gone. Then it intuitively changes temperature settings for the best savings. How much exactly? About $180 annually on heating and cooling, according to ENERGY STAR.

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

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

We recommend trying a comparable test over a week, putting your temperature higher and gradually decreasing it to find the ideal setting for your residence. On pleasant nights, you may find keeping windows open at night and using a ceiling fan is a superior option than operating the air conditioning.

More Approaches to Use Less Energy During Hot Weather

There are other approaches you can conserve money on air conditioning bills throughout warm weather.

  1. Get an energy-efficient AC system. Central air conditioners only are effective for about 12–15 years and lose efficiency as they age. An upgraded air conditioner can keep your home cooler while keeping utility
  2. expenses small.
  3. Set regular air conditioning tune-ups. Routine air conditioner maintenance keeps your equipment operating like it should and might help it run more efficiently. It may also help extend its life span, since it helps pros to find seemingly insignificant problems before they cause an expensive meltdown.
  4. Put in new air filters regularly. Read manufacturer instructions for switching your air filter. A dusty filter can cause your system to short cycle, or switch on and off too much, and increase your cooling
  5. bills.
  6. Measure attic insulation levels. Just about 90% of homes in the USA don’t have adequate insulation, according to the Insulation Institute. The majority of southern climates require 13–14” of attic insulation, while northern climates need 16–18”.
  7. Have your ductwork inspected. Ductwork that has separated over the years can let conditioned air into your attic, walls or crawl space. This can lead to major comfort issues in your home, like hot and cold spots.
  8. Seal holes, doors and windows. Keep warm air in its place by plugging openings. You can also caulk or weather strip doors to trap more conditioned air inside.
