Most people know that turning up the thermostat on their air conditioner to a higher temperature will result in cooler air blowing from the vents. However, there is a point at which increasing the temperature any further does not make the air cooler – it just uses more energy and costs more money.
But setting the thermostat really low doesn't increase your air conditioner's cooling capacity. “People think, 'If I make the thermostat set point 60, I'll get more cooling than a set point at 70,' but that's not correct,” Liu said. “You get the same amount of the cooling.”
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.
The Air Conditioner is a machine for making the room cold. Turning the machine up means increasing its function, resulting in more cold; and turning it down means decreasing the function, causing less cold and more warmth.

Set a reasonable temperature: HVAC professionals strongly recommend never setting the thermostat lower than 68 degrees in the summer. To balance comfort and energy efficiency, the Environmental Protection Agency recommends setting your thermostat to 78 degrees when you're at home and awake.
For many of us, 70 degrees is the ideal indoor temperature, but when it is close to 100 degrees outside, your AC unit will be working quite hard to meet these expectations. Consider setting your thermostat at 75 degrees to 80 degrees in your home if the outside temperature is approaching triple digits.
What is the Best Thermostat Setting for Summer Air Conditioner Use? Energy Star recommends the following thermostat temperatures for your air conditioner in the summer: 78°F during the day if people are home. 82°F at night if people are home.
Most people work better and are more productive when with a temperature setting in the 72–74-degree range. This setting is low enough to keep the house cool and dry and keep you and the kids awake during the afternoon hours.
As mandated by the Ministry of Power, Government of India, all AC manufacturers must fix the default temperature setting at 24°C. So, it is better to set the right temperature at about 24-25 degrees Celsius. This will help in cooling the room faster.
Cool mode
This is the most common and usually the default setting when you first turn on the AC. This mode sends cool air throughout your room and is great for cooling down an area after a long, hot day.
HVAC experts will tell you all the same thing: turning your thermostat to a lower setting DOES NOT cool your home faster.
As it turns out, the most efficient way to keep your home cool and the bills low is to leave the AC running—ideally, with the temperature turned up toward the upper 70s.
Quick answer: The ideal house temperature is room temperature, which ranges from 68 to 78 degrees F, though this may vary from season to season. In winter, the average room temperature is generally 62 to 68 degrees, whereas in the summer, the average temperature is 72 to 78 degrees.
This is more of a personal question, as different people feel comfortable at different temperatures. Since 72 degrees is generally agreed upon to be an ideal indoor temperature, most people would probably still feel comfortable setting their AC units slightly higher than this, perhaps at around 75.
There are benefits to having your air conditioner set to “auto” and “on.” The benefits of the “auto” setting include higher efficiency, lower energy bills, better humidity control, less wear and tear on some components, and quieter running.
Here's the thing: It's normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we're talkin' high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.
Cooling a house from 80 to 72 degrees is a common goal for many, especially during the peak of summer. On average, this process takes roughly two and a half to three and a half hours.
The California Energy Commission recommends that homeowners set their thermostat to 78 degrees when they're home and 85 degrees when they're away from home during the summer.
What's The Ideal AC Temperature? Generally, when you are at home, your A/C's ideal temperature is between 76- and 78-degrees Fahrenheit. If you spend most of the day away from the house, set the thermostat a few degrees higher instead of cooling your home for no reason.
The best way to save money is by combining both. The “run” feature lets you preset the temperature when you're not home to prevent wasting money on cooling or heating an empty home. Meanwhile, the “hold” button lets you change the room's temperature without changing your energy-saving, preset schedule.
Cool mode: Ideal for hot days, this mode reduces the room temperature to your desired setting. Dry mode: Perfect for humid conditions, this mode removes excess moisture from the air without significantly reducing the temperature.
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.
