Some will say 21-23 degrees is the best setting for ultimate comfort but at the end of the day it comes down to personal preference. It is important to keep in mind that some people tend to feel cold more than others.
The Ideal Air Conditioner Temperature Setting Is 22-26°C
Not too hot, not too cold, but just right. Studies have shown that for each degree you raise your thermostat, you can save 3-5% on cooling costs.
For example, the ideal temperature of a living room should be around 20 to 22 degrees. This is a room for relaxing in, and where you sit for long periods of time, meaning it should be on the warmer side. Meanwhile, the best temperature for a bathroom or child's bedroom should be warmer too at 22 to 24 degrees.
The ideal temperature to set your air conditioner cooling cycle to in summer is between 24 and 25 degrees (23 is fine if you want it that bit cooler). In winter we recommend setting the aircon heating cycle at 20 or 21 degrees. Some homeowners choose to set their systems at 24 degrees all year round.
HVAC manufacturers typically advise users not to run their units for extended periods if the temperature is below 65 degrees Fahrenheit. If you need to test your unit, you should do so after the weather has been risen to 60 degrees Fahrenheit for at least three days.
The Normal human body temperature is 36-37 degree celsius. Hence, to take a temperature closer to 24 degrees is considered to be healthier for individuals in tropical regions like India.
Most air conditioning systems can only handle a 20-degree difference between the outside and inside air temperatures.
If you're setting your air conditioner in cooling mode, doing so at lower than 21C will normally be regarded as too cold to have much impact and is generally wasteful of electricity.
On average, the best air conditioner temperature setting for summer in Australia is around 23℃ – 24℃ for comfort or 25℃ – 27℃ for maximum energy savings. In winter, reverse cycle heating should be set to around 18℃ – 20℃.
The ideal indoor temperature for keeping utility bills low is typically between 21 and 23 degrees Celsius during the day and between 20 and 22 degrees Celsius at night. By setting your thermostat to these temperatures, you can save on your energy bills without sacrificing too much comfort.
There may be drafts and pockets of colder air near the floor; The walls are colder and don't emit the usual amount of infrared radiation, so you lose heat due to your body emitting more IR than it receives; You may spend more time indoors and hence have less physical activity, so your body generates less heat.
The most comfortable room temperature will vary based on your personal preferences, the season, and which areas of the home you are living in. Most people can agree that a healthy range will go from 20 – 24 degrees Celsius (68 – 76 degrees Fahrenheit).
Temperature settings lower or higher than the recommended 18-22 degrees can lead to disrupted, restless sleep, leaving you exhausted the next morning. Whether it's your room temperature or body temperature, most of us have experienced the feeling of being too hot while sleeping.
The ability to resist certain temperature can vary from person to person. However, in general 22 degree Celsius is not considered very hot and does not require a ceiling fan unless there is a cross ventilation in the room. and 0 degrees C is equivalent to 32 degrees Fahrenheit.
What temperature is too cold for air conditioning? Air conditioning units are set to go no lower than 17°C for a reason. At colder temperatures, condensation can start to develop on your property's walls which can potentially cause damp and also reduce the performance of the air handler due to icing up issues.
Speaking with indianexpress.com, Dr Rajat Agarwal, Additional Director, Critical Care Medicine, Fortis Escorts Heart Institute said, “It is advisable to maintain the AC temperature at 24-25 degrees Celsius as it is considered most optimum for healthy bodily functions.”
However, no matter how diverse climates can be, many Australians prefer an air conditioner setting of 22 degrees in the summer months and 19 degrees in winter.
In the summer, experts believe the thermostat for your air conditioner should be set to at least 78°F during the day when people are at home. That setting is designed to help people avoid high energy bills in the summer. The lower your thermostat setting, the higher your bill.
According to the Department of Energy1, 78° Fahrenheit is the sweet spot for air conditioners to balance energy savings and comfort when people are at home and need cooling. But in reality, this is a question that doesn't have a “one size fits all” answer.
Average Air Conditioning Temperature
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. The same was true for the winter months. However, this could differ based on energy costs in the region.
“What temperature should air conditioning be set at in summer” Direct energy recommends keeping your home's temperature set to 78 degrees f (25c) to get the most out of your electricity bills in the summer.
“We've noticed how people set their ACs at 18-19°C. But they also wrap themselves in something warm all the same. It's best to keep it in the range of 25-30 degrees Celsius,” Sakshi Dasgupta, deputy program manager, sustainable buildings, CSE, said.
Remember that when you see a weather forecast on TV, in a newspaper or on the radio, that anything from 20 degrees upwards is going to be warm, above 25 degrees is hot, above 30 degrees is very hot.
If the AC system is operating correctly, then the air coming out of your vent should be about twenty degrees cooler than the regular temperature inside. So, if you're cooling it and the house is 80 degrees, then you would ideally want the air to be about 60 degrees. Have more air conditioner questions?
This creates a negative impact on the environment. Instead of keeping the air conditioner (AC) temperature at 18 degrees and then taking a blanket, it's better to keep the AC temperature at 24 degrees and reduce electricity consumption,” Modi said.
