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 home at a refreshing temperature during the summer.

But what is the ideal temperature, exactly? We go over suggestions from energy pros so you can select the best setting for your home.

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

Recommended Thermostat Settings for Summer

Most people find placing the thermostat at 72-73 degrees provides ideal comfort. However, if there’s a big difference between your indoor and outside temperatures, your AC expenses will be larger.

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

While at home: 78 degrees. While that seems warm, there are ways you can keep your house refreshing without having the air conditioning going frequently.

Keeping windows and blinds down during the day keeps cool air where it belongs—within your home. Some window solutions, like honeycomb shades or plantation shutters, are created to deliver added insulation and better energy savings.

If you have ceiling fans in your home, the DOE says you can raise thermostat temperatures about 4 degrees warmer without giving up comfort. That’s due to the fact they refresh with a windchill effect. Because they cool people, not areas, switch them off when you leave a room.

If 78 degrees still appears too hot at first glance, try doing a trial for about a week. Start by increasing your thermostat to 78 degrees while you’re home. Then, gradually turn it down while using the tips above. You may be shocked at how cool you feel at a hotter temperature setting.

While away: 88 degrees. There’s no rationale for keeping the air conditioning on all day while your house is empty. Turning the temp 7¬¬–10 degrees higher can save you an estimated 5–15% on your electricity bills, according to the DOE.

When you come home, don’t be tempted to set your thermostat under 78 to cool your residence faster. This isn’t useful and typically produces a higher cooling expense.

A programmable thermostat is a useful approach to keep your temperature controlled, but it requires setting programs. If you don’t use programs, you might forget to change the set temperature when you take off.

If you want a hassle-free solution, consider buying a smart thermostat. This thermostat connects with your phone, so it knows when you’re at home and when you’re out. Then it automatically changes temperature settings for maximum savings. How much exactly? An estimated $180 yearly on heating and cooling, according to ENERGY STAR.

Another benefit of having a smart thermostat? You can use your phone to watch and change temperature settings from almost anywhere.

While sleeping: Around 70 degrees. While ENERGY STAR recommends 82 degrees, that might be unbearable for many families. Many people sleep better when their sleeping area is cold, so that’s why the National Sleep Foundation suggests 60–67 degrees. But that might be too chilly, depending on your clothing and blanket preference.

We recommend running a similar test over a week, putting your temperature higher and steadily decreasing it to find the best setting for your house. On pleasant nights, you could learn keeping windows open at night and relying on a ceiling fan is a better idea than operating the air conditioning.

More Approaches to Use Less Energy During Hot Weather

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

  1. Get an energy-efficient cooling system. Central air conditioners only work for about 12–15 years and lose efficiency as they age. An updated air conditioner can keep your residence comfier while keeping electrical
  2. bills low.
  3. Book regular AC tune-ups. Routine air conditioner maintenance keeps your system operating smoothly and may help it run at better efficiency. It may also help lengthen its life expectancy, since it helps professionals to discover seemingly insignificant issues before they create a major meltdown.
  4. Put in new air filters often. Read manufacturer instructions for switching your air filter. A dirty filter can cause your system to short cycle, or run too much, and raise your utility
  5. costs.
  6. Measure attic insulation levels. Just about 90% of homes in the United States don’t have proper insulation, according to the Insulation Institute. The majority of southern climates need 13–14” of attic insulation, while northern climates require 16–18”.
  7. Have your ductwork inspected. Ductwork that has separated over the years can leak cool air into your attic, walls or crawl space. This can lead to big comfort problems in your residence, such as hot and cold spots.
  8. Seal cracks, doors and windows. Keep warm air in its place by sealing openings. You can also caulk or weather strip doors to keep more cold air inside.
