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.
To achieve optimal comfort, it is recommended for homeowners to set their thermostats between 68 to 72 degrees while there are people inside of the home.
The World Health Organization (WHO) recommends setting your thermostat no lower than 64 degrees (F) in the Winter months while people are in the home. If there are infants or elderly individuals, they recommend keeping the temperature at 70 degrees at a minimum.
Different sources disagree on a maximum indoor temperature setting in winter. 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.
While the standard room temperature of 72 degrees Fahrenheit is commonly favored by many, others argue for higher settings, particularly when it's hotter outside.
The EPA says that for every degree warmer you set your AC, you can save 6 percent on your cooling costs, although you get diminishing returns as you go higher and higher. Put simply, if your cooling bill is usually $170, setting your thermostat a single digit higher will save you over $10 a month.
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.
Why does 70 inside feel different in the winter compared to summer? There are multiple factors but the main reason is the dry air. Dry air causes evaporation of the moisture from our skin which in the process makes us feel cooler. Meanwhile humid air hinders evaporation doing the opposite.
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.
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.
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.
Everyone is different, and that's definitely true when it comes to ideal room temperature. That being said, the average room temperature in most homes falls somewhere between 68 and 76°F.

Cooling a house from 90 degrees to 72 degrees typically takes about 2 to 4 hours, depending on various factors.
The Ideal AC Temperature
Between 74-77 degrees F (23-25 degrees C). This will limit the strain on your cooling system, keep energy bills reasonable, and help prevent the coils from freezing.
How warm does it have to be before you start wearing SHORTS? A new survey on YouGov.com asked people to name the lowest temperature that they believe is warm enough to wear SHORTS outside. The most common answer was between 61 and 70, which got 25% of the vote. Between 71 and 80 came in second, with 23% of the vote.
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.
When deciding what temperature to set your thermostat to, avoid going below 63 degrees. Temperatures below 63 degrees Fahrenheit can cause mold and mildew growth or increase allergens.
Cold air inflames lungs and inhibits circulation, increasing the risk of respiratory conditions, such as asthma attacks or symptoms, worsening of chronic obstructive pulmonary disease (COPD), and infection.

The average room temperature is between 68 and 72 degrees Fahrenheit. The normal house temperature in Celsius is 20 and 22 degrees. Ideal room temperature reflects the degree of comfort people feel indoors. An 'optimal temperature' means occupants aren't sweating or shivering wearing normal daily attire.
Setting your thermostat just a single digit higher can help you save 6 percent on your cooling costs, according to the EPA.
Make sure your home is warm enough. Set your thermostat to at least 68 to 70 degrees Fahrenheit (F). Even mildly cool homes with temperatures from 60 to 65 degrees F can lead to hypothermia in older adults. To stay warm at home, wear long underwear under your clothes, along with socks and slippers.
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.
During heat waves, experts, including utility companies, recommend keeping your thermostat no more than 20 degrees cooler than the outdoor temperature. For instance, if it's 100 degrees outside, aim to set your thermostat to at least 80 degrees.
