ASHRAE, unlike the EPA, specifies an ideal number to set a building's thermostat to. It's a range, actually: around 23°-26°C, or 73.4°-78.8°F, in the summer.
It is generally safe to leave your wall air conditioner on and set to a specific temperature, such as 72 degrees, for extended periods of time. Modern air conditioning units are designed to handle continuous operation and maintain a consistent temperature. However, there are a few factors to consider:
When temperatures exceed 100 degrees Fahrenheit outside, setting your air conditioning (AC) to around 75-78 degrees Fahrenheit is generally considered efficient. Here are some reasons for this recommendation:
Your thermostat can go up to 90°F, but you shouldn't push it that far for monetary reasons. Not only will it drain power and cause a huge jump in your bills, but it will force your heater to work harder and wear down much faster.
The World Health Organization recommends a thermostat setting no lower than 68 degrees while you're home. If you have children or seniors in your house, that number increases to at least 70 degrees. If your house is too cold, it can cause problems with blood pressure and circulation, as well as affect your heart rate.
Just because the outdoor temperature is above 100, the Ideal temperature to set your AC unit to doesn't change — it's 78 degrees. Higher temperatures in the home are to be expected when the weather is hotter than usual, but your thermostat can still be set the same as if it were a lower temperature outside.
Cooling a house from 90 degrees to 72 degrees typically takes about 2 to 4 hours, depending on various factors.
For the most efficient performance, set the thermostat 20 degrees lower than the temperature outside. On a 100℉ day, set it to 78℉ to 80℉ to manage utility costs. If there's a lack of airflow, the filter may need to be changed or AC vents cleaned. But it may also mean your air conditioner needs professional repair.
Setting your thermostat just a single digit higher can help you save 6 percent on your cooling costs, according to the EPA.
The average air conditioning temperature depends on a variety of factors, including geographic location, comfort levels, season, and cost of energy. Anywhere between 72° to 78°F is typically standard. A study in Texas revealed that the model temperature during summer months was between 70° and 75°F.
For most people, 75 degrees is too hot to sleep, per the National Sleep Foundation. But the new study found that in people 65 and up, sleep efficiency only started to decrease when temperatures were above 77 degrees.
Setting your air conditioning to 72°F is generally considered a comfortable indoor temperature for many people. It strikes a good balance between comfort and energy efficiency, making it a popular choice for residential settings.
Sleep experts believe the best temperature for great sleep is between 68-72 degrees Fahrenheit. But in addition to making you uncomfortable and interfering with healthy sleep patterns, being too hot at any time of day or night can cause health risks like dehydration and heat stroke.
What temperature should you keep your house at? Or better yet, “What is the most energy saving temperature to set my thermostat at?” According to ENERGYSTAR.gov, the ideal home temperature should be between 70 to 78 degrees Fahrenheit.
Some of the basics include: turn your thermostat up a couple degrees and deal with 76 to 78 degree temperatures indoors for a few days. close off unused rooms. close doors and vents.
If you're cold even though your thermostat indicates you shouldn't be, your furnace likely isn't the problem. In most cases, it's working just fine. It's your home that needs attention. Lack of insulation, severe air leakage, and/or unbalanced ductwork are frequently to blame.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Best AC Temperature Settings While You Are Home
As you consider the most comfortable room temperature for your lifestyle and family, keep in mind that for each degree that you set your thermostat above 72 degrees, you can save up to 3% on your energy bill.
For instance, if it's 100 degrees outside, aim to set your thermostat to at least 80 degrees. Adhering to the 20-degree rule maintains energy efficiency, prevents strain on your cooling system, extends its lifespan, and promotes lower energy bills and consistent indoor comfort.
Sleeping in a room with the air conditioner set to an appropriate temperature is important for quality sleep. The ideal AC temperature for sleeping is around 65°F (18.3°C). However, this may differ between individuals, who might find their ideal AC temperature lies between 60 and 67°F (15.6 and 19.4°C).
However, 72 degrees is the average recommendation. Setting the thermostat higher than the low 70s inevitably increases heat loss to the outdoors, raising heating bills substantially.
It's important to avoid excessively high settings, as not only does it lead to unnecessary energy consumption but can also strain the heating system and potentially create discomfort.
There is no “Right Answer” but generally speaking an average adult will sleep comfortably somewhere between 68 and 75 degrees. Comfort is personalized. Some people like to sleep hot, some cold, some want a lot of weighted blankets to feel comfortable, and some are ok with a sheet only.
