AC Temperature: Best Temperature For Sleeping

Air conditioning can make the scorching summer months bearable, giving you a cool, dry oasis away from the sweltering heat and humidity. Many people have different views on where the thermostat should be set, which can cause turmoil in households, particularly during the summer months.

However, various studies indicate the best temperature to set your air conditioner at throughout the year. This article delves into AC temperatures and which settings are the best in different scenarios, so continue reading to learn more.

Average House Temperature

The average house temperature is highly dependent on the area, time of year, and the occupants. Warm climates tend to have higher home temperatures. For example, a house in Hawaii may not be as cool throughout the year as the air conditioner would have to work overtime to keep up with demand.

Or, in a cold temperature, like in northern Alaska, homes may remain cooler, as constantly running the furnace would cause electricity costs to rise substantially. The time of year can also play a role in the average house temperature.

Additionally, some people prefer to set their thermostats much lower than others. Many families may have drastically different views on the thermostat’s setpoint, which can be problematic.

Recommended Thermostat Settings

Although all people are different, many individuals can agree on a general thermostat setting range. The best thermostat setting for your home is dependent on several factors, such as your preferences, where you live, and so on.

What Is The Best Temperature To Set Your Air Conditioner On

What’s a suitable temperature for AC? Although everyone has their preferences, the Department of Energy states that 78 degrees Fahrenheit is the perfect balanced temperature for the summer months. This typical AC temperature is supposedly the ideal balance between energy savings and comfort for warm months when people are at home.

What Temperature Should I Set My Air Conditioner In Summer

What is a good temperature to set your thermostat in the summer? In warm weather, most experts recommend that you put your air conditioning system to 78 degrees when you’re home. If you plan on stepping out for four or more hours, you may want to raise the setting so you don’t waste energy on cooling your home when you won’t be home to reap the benefits.

However, many people agree that when you’re home, 78 degrees is the best AC temperature for summer.

What Temperature Should I Set My Thermostat In Winter

If you’re wondering what temperature to set your air conditioner in the winter, you’re not alone. It’s a common question, though most areas use their heater in the winter. In the winter months, you can save energy and regulate your electricity costs by setting your thermostat at 68 degrees during the day. 

If you live in an area that experiences sub-zero temperatures, you need to be cautious of turning your thermostat off when you’re away or at night, as you could cause pipes in your home’s exterior walls to freeze. So, the best temperature for your heater in the winter at night is dependent on where you live.

Best Sleeping Temperature

According to various studies, the best AC temperature for sleeping in the summer is between 60 and 67 degrees Fahrenheit. Most people tend to sleep better in cooler rooms, and scientists believe a cooler environment may promote REM sleep stability, which is an important stage of our sleep cycle.

Although the comfort levels of each individual are different, studies say the optimal sleeping temperature is about 65 degrees Fahrenheit.

Best Temperature For AC To Save Money

Studies state you can save the most on your cooling costs by setting your air conditioning unit to 78 degrees Fahrenheit in the summer months. It’s a moderate level that isn’t overly high or low, which can help your home stay cooler than outside while also avoiding unusually high electricity bills.

You can save up to 10% on annual cooling costs simply by turning up your thermostat between seven and ten degrees for eight hours per day. So, for the ideal AC temperature to save electricity, set your thermostat seven to ten degrees lower than the outdoor temperature.


1. Thermostat Not Reaching Set Temperature AC

If your thermostat isn’t reaching the set temperature, several things could be happening. You may need to calibrate the thermostat, redo the wiring, or clean it. If you’re unsure how to complete these tasks, call in an HVAC technician, as they have the tools and skillset necessary to complete the repair.

2. What Temperature To Set Air Conditioner When Away

When you’re away, you should set your thermostat to no higher than 84 degrees if it is in the summer months and the outdoor temperature is regularly in the high 90s.

The best temperature in the spring and fall months is tricky to specify, as the system needs to run a few hours per day to cool and dehumidify your home. For these seasons, set your thermostat a few degrees lower than the daily high temperature as a general rule of thumb.

3. Is 72 A Good Temperature For Air Conditioning

The answer to this question falls to personal preference, as most people feel comfortable at varying temperatures. However, at 72 degrees Fahrenheit, many people agree they feel comfortable. Some people may choose to set their AC units slightly higher, perhaps at 75 degrees.

4. How Long Should AC Run After Reaching Temperature

In an ideal situation, your air conditioning unit should run in cycles. It should run 15-20 minutes at a time in mild temperatures, cycling a few times per hour to keep your home at the specified temperature.

However, the run time will increase when the temperature inside or outside is much higher than the thermostat setting.

5. How Low Can You Set Your AC

Generally, a good air conditioner can drop the temperature by about a maximum of 20 degrees Fahrenheit, which is about the coldest it can go. You can set it as low as 60 degrees Fahrenheit for most air conditioners.

6. What Is The Coldest Temperature For An Air Conditioner

Generally, the coldest setting you can set your AC unit is 60 degrees. This is because most manufacturers automatically assume you won’t be using the thermostat when outdoor temperatures are 60 degrees Fahrenheit.

7. Does Outside Temperature Affect Air Conditioner

Absolutely, the outside temperature can affect your air conditioner. If your house is poorly insulated, sits in direct sunlight, has numerous doors and windows, or the like, your air conditioner may have to work harder to cool your home.

If temperatures outside are soaring, your AC unit will have to work hard to bring the indoor temperature down.
