Considerations for Setting Your Thermostat This Summer By setting your thermostat between 80 and 85 degrees F, you ensure that your AC runs occasionally to keep humidity in check. Energy efficiency: While it might seem counterintuitive, allowing your AC to run occasionally can be more energy-efficient.
Normal. 115-80=35 degrees cooler than outside temps. Pretty good for a standard residential AC. Lots of factors go into this though. Size of unit per square feet, age of unit, clean filters, recent maintenance on unit, insulation of house, etc.
In general, 80 degrees is too hot for a house if people are inside. However, if people aren't home during the day or for vacation during the summer, an indoor temperature of 80 degrees can save energy until you return and lower the temperature.
The average temperature that can help you save money is anywhere from 70 to 80 degrees Fahrenheit, giving your house just enough cooling to keep the hottest temperatures outside at bay.
If your thermostat is set at 80+ degrees, then the humidity inside of your home can easily get up above 70%. That's much higher than the recommended ideal indoor humidity of 30-50%. Having indoor humidity above 50% can cause serious issues for your health and your home.
While ENERGY STAR suggests 82 degrees, that may be too uncomfortable for most families. Most people sleep better when their sleeping area is chilly, so that's why the National Sleep Foundation advises 60–67 degrees.
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.
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.
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.
Most experts agree that a temperature as high as 85 degrees Fahrenheit is safe for your home while you are at work or away on vacation.
Most sleep specialists recommend people sleep in a “cool, dark and quiet environment,” typically ranging from about 65 to 75 degrees, said Ronald Chervin, the division chief of the sleep disorders centers and professor of sleep medicine at the University of Michigan, who was not involved in the study.
A dirty air filter
Your air filter is designed to trap contaminants in the air before it gets pulled into the AC system. But over time that means that your filter gets dirty and clogged. And if a dirty filter isn't replaced, it can seriously limit your AC's cooling power.
The recommended rule of thumb for summertime is to set the temperature to 78 degrees Fahrenheit when you're home and higher when you're away. In general, set it to 82 degrees Fahrenheit when you're asleep and 85 degrees Fahrenheit when you're away.
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.
If it's 80 degrees outside, and your thermostat is set to 78 degrees, it shouldn't run as long as it would if it were set to 72 degrees. In either scenario, however, the unit should reach your desired temperature – typically within 15 or 20 minutes – and should cycle off for at least seven to 10 minutes.
It's advisable to keep your home below 80 degrees throughout the summer. A house that's too warm can be dangerous to people, pets, and the soft surfaces in your home. Set the winter temperature to 68 degrees when you're awake and 62 degrees when you're sleeping.
Recommended AC Temperature for Sleeping
The Sleep Foundation says 65° is the best temperature for sleeping. However, if you prefer a slightly warmer or cooler room, that's okay, too. The recommended range is 60–68°, so there is some wiggle room.
AC definitely consumes more power than a Fan or a cooler, and how many hours will run AC depends on that your electricity bill will shoot up.
A more moderate setting like 24°C (75.2°F) can achieve comfort with reduced electricity usage.
The National Sleep Foundation says 60-67 is a good temperature for sleep, but that might be too cold for you and increase your cooling bill. As a compromise, 70-plus degrees is a good setting.
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 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.
Heat Index: 80-89 degrees F Heat Effect: Fatigue is possible with prolonged exposure and/or physical activity Recommendations: Limit your time outdoors; Stay well-hydrated.
Cats' heat tolerances vary depending on their breed, age, and overall health. Your feline's risk of heatstroke and other heat-related health complications gravely increases when the temperature is 80°F or above.
