This temperature strikes a perfect balance between staying comfortable and saving energy. A temperature of 68 degrees Fahrenheit is often considered the best temperature to set thermostat in winter to save money.
A good temperature to set your thermostat in the winter is typically between 68°F and 72°F (20°C to 22°C) when you're at home and awake. When you're sleeping or away, you can lower it by a few degrees (around 60°F to 65°F or 15°C to 18°C) to save energy.
A temperature of 72°F (22°C) is generally considered a comfortable setting for air conditioning. It strikes a balance between comfort and energy efficiency. Here are some points to consider:
The standard air conditioner's temperature should be set around 18 to 22 degrees under Heat Mode for heating in winter. This is to ensure maximum energy efficiency from your unit. The Fan speed of the AC should be kept between Low to Medium.
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.
When possible, set your thermostat to at least 78º F in the summer to reduce the difference between outdoor and indoor temperatures as much as possible. You can save six to eight percent on your electric bill for every degree your thermostat is raised above 78º F in the summer, according to Smart Energy.
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.
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). A cool room helps people get quality sleep, in part due to its effect on circadian rhythms, which control bodily processes, such as core body temperature and the sleep-wake cycle.
Heating Mode: Your Winter Companion
The heating mode works by reversing the standard cycle of an air conditioner, creating warm air instead of cold air, which is necessary for a comfortable temperature indoors during winter.
The turbo mode is the most powerful. It's for absolute quick cooling. It allows users to cool a room quickly and effectively by operating at a span of 30 minutes before switching back to the previous settings.
68 to 72 degrees is a temperature range that is not too warm or cool, and is sufficient enough to warm up the home just enough so that everyone is comfortable regardless of the type of clothing they have on.
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.
A common rule of thumb is that most models can function properly only above 68 degrees Fahrenheit. Any lower temperature will result in the system freezing up. In addition to a frosty refrigerant, the piping and coils could also become covered with ice.
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.
Set an Appropriate Temperature: For winter heating, a setting between 18°C to 22°C is often recommended. This range is comfortable for most people and energy-efficient. Take Advantage of Timers: Use your system's timer function to heat your home before you wake up or return home, rather than leaving it running all day.
If someone is at home in the daytime, 72° F (22° C) is a good start, but aim for 68° F (20° C). If everyone is away from home in the daytime or you're asleep at night, we feel 66° F (19° C) to 62° F (17° C) is best.
Did you know that air conditioners (AC) have an ideal temperature that you should use on different seasons? Yes, there is! During summer, the ideal temperature to set your AC is 22 – 24 degrees. While during winter, it's more ideal to set it on 20 – 22 degrees.
The Department of Energy recommends a winter heat setting of 68 °F (20 °C), which matches up very well with the temperatures most of us are comfortable with.
Running the “auto” function of your air conditioner all day and night isn't the best idea for any home. There are a few reasons you don't want to run your AC system all the time: System stress: Your air conditioner unit needs time to take a break.
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.
The best room temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius). This may vary by a few degrees from person to person, but most doctors recommend keeping the thermostat set between 65 to 68 degrees Fahrenheit (15.6 to 20 degrees Celsius) for the most comfortable sleep.
On work days, you can set the temperature a few degrees higher when you usually leave the house, and then have it start cooling down to your ideal temperature 30 minutes before you return. If you don't have an ideal temperature, the DOE recommends using a baseline of 78 degrees when at home for the most savings.
If the temperature is set to 74°F but the thermometer shows 78°F, you will have to recalibrate the thermostat to account for this 4-degree deviation. Even with older AC units or furnaces, you might have to recalibrate your thermostat from time to time.
Your AC might not cool properly due to thermostat issues, an undersized unit, or extremely high outdoor temps—so check those first. Keep an eye on airflow—replace clogged filters every 3 months, and make sure vents and ducts aren't blocked for efficient cooling.
