Generally, air conditioning specialists recommend between 21-22 degrees in winter, and 24-25 degrees in summer to ensure maximum energy efficiency for your unit.
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.
Everyone is different but from our experience 22°C for either cooling or heating modes is the consensus norm. There is no one correct answer, instead, it's best to consider everyone and find a balance between those who like it cooler and those who want some extra warmth.
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.
Most air conditioning systems can only handle a 20-degree difference between the outside and inside air temperatures.
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.
“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.
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.
The first problem with setting your thermostat too low is that it forces your AC to work harder. The system has to run longer to get your home to that lower temperature, which not only wastes energy but wears the system out more quickly, leading to frequent repairs and ultimately shortening the unit's life span.
The Best AC Temperature for Sleep
The National Sleep Foundation recommends an optimal range to promote sleep, which is between 60 degrees and 67 degrees. Be mindful that this recommendation is for adults. For infants, for instance, the general recommendation is between 67 degrees and 69 degrees.
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℃.
“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.
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 practice, you should be heating your home based on the age and health of your household. The WHO suggests 20 degrees as the ideal temperature for the old, young or unwell. For healthy adults, you should heat your home to a room temperature that feels comfortable.
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.
In most cases, the ideal temperature indoors is one that is set somewhere between 20 and 23 degrees Celsius.
Thus, temperature setting below 68 degrees is generally not recommended for optimal performance. The ideal temperature lies between 75 to 78 degrees.
HVAC experts will tell you all the same thing: turning your thermostat to a lower setting DOES NOT cool your home faster. Setting your thermostat to 65 degrees will not get your home cooler faster than setting it at 73.
In most cases, especially in residential applications, you should not run your air conditioner when outdoor temperatures are below 60 degrees. The air conditioner does function, but you are going to burn out the compressor fairly quickly.
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. This is especially true for the young and old and can also be due to other factors such as health.
According to most professionals, the ideal temp for ac is between 22 and 26 degrees Celsius. Most people find this is the ideal air conditioner temperature range.
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.
People often think that setting the AC at 16 degrees will provide better cooling, but that's not really the case. As per the Bureau of Energy Efficiency (BEE), the ideal temperature for the human body is 24 and any AC will take less load to achieve that target. So, it is better to set the AC temperature around 24.
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.
A long-sleeved T-shirt or light knit will come in handy.” A long-sleeved long T or a thin knit one can be comfortable in the daytime when the maximum temperature is 21 degrees Celsius. We recommend enjoying an adult's relaxing coordinate with high quality clothing made of carefully selected materials.
