Find Out the Best Temperature Setting for Your Thermostat
You’ve been asking yourself this question for a while now—what is the ideal temperature setting for my thermostat? We get it, you want to know the best temperature for your house during the hottest and coldest months, in order to feel optimal comfortable in your space while keeping energy efficiency in mind. Well, read on to find out the best thermostat setting for winter and summer, along with energy savings.

What Is a Thermostat?
Before talking about the ideal temperature setting for the thermostat, let’s talk about what a thermostat is and how important it is. A thermostat is a device used to regulate and maintain a desired temperature within a specific environment, typically in buildings and HVAC systems. It’s an important device because it helps control the heating and cooling systems to maintain a comfortable and consistent temperature level.
Its primary function is to monitor the current temperature and compare it to the desired set point temperature. Based on this comparison, the thermostat can either activate or deactivate the heating or cooling system.
When the temperature exceeds the set point, the thermostat signals the system to cool or activate the air conditioning. Conversely, if the temperature falls below the set point, the thermostat signals the system to heat or activate the heating system. With this, it is obvious thermostats play a crucial role in maintaining energy efficiency and comfort.
Types of Thermostats
● Manual Thermostats
These are basic thermostats that require manual adjustment to set the desired temperature.
● Programmable Thermostats
These thermostats allow users to program temperature setting for different times of the day or week.
● Smart Thermostats
These are advanced thermostats that connect to Wi-Fi and can be controlled remotely through a smartphone app. They often have additional features like learning capabilities and energy usage reports.
What Is the Best Temperature Setting for the Thermostat?
According to ENERGY STAR, the ideal temperature setting for a thermostat when you are home is 68 degrees Fahrenheit or 20 degrees Celsius. It’s a good number for a nice balance between comfort and energy efficiency. However, keep in mind that various factors may change this temperature setting, such as the time of year and the climate you live in.
Cold Season
In the winter or heating season, the recommended temperature setting is 68 degrees Fahrenheit or 20 degree Celsius when you’re at home. The same as the ideal temperature setting for the thermostat mentioned above. This provides a comfortable indoor environment while still being energy-efficient.
Hot Season
What temperature should you set the air conditioner to in the summer? Well, the ideal temperature setting during summer or cooling season is around 78 degrees Fahrenheit or 25.5 degrees Celsius when you’re at home. This likewise makes your space comfortable while staying energy-efficient. But if you feel too warm, you can lower it slightly, keeping in mind that each degree cooler can increase your energy usage by about 3-5%.
When Away or Sleeping
When you’re away from home or sleeping, you can adjust the temperature to save energy. During the cool season, you can set the thermostat a few degrees higher around 85 degrees Fahrenheit or 29 degrees Celsius when you’re away. In the heating season, you can set it a bit lower at around 60 to 65 degrees Fahrenheit or 15 to 18 degrees Celsius.
Remember, these are general recommendations. You should adjust the temperature in your home to your personal comfort level. Also, consider using programmable or smart thermostats that allow you to schedule temperature adjustments based on your daily routine. This way, you can have a comfortable environment when you’re home while optimizing energy usage when you’re away.

How to Set AC Temperature for Cooling?
Now that you know the ideal temperature setting for the thermostat, your next question is, “How to set the AC temperature for cooling?” Well, let’s get on it and learn how to set up your thermostat for cooling and ensure your home is as comfortable as it can be.
1. Determine Your Comfort Level
Everyone has their own preferred temperature for comfort. Consider the temperature at which you typically feel most comfortable during the summer months. A range of 75-78 degrees Fahrenheit (24-26 degrees Celsius) is commonly recommended. However, individual preferences may vary, so choose a temperature that suits you best.
2. Start With a Higher Temperature
To promote energy efficiency and save on cooling costs, it’s generally advised to set the thermostat a few degrees higher than your desired comfort level. By setting the temperature a bit higher, such as at 78 degrees Fahrenheit (26 degrees Celsius), you can help reduce energy consumption and lower cooling expenses.
3. Adjust Based on Personal Preferences
After setting the initial temperature, monitor how it feels over the next few hours. If you find the temperature to be too warm or too cool, make gradual adjustments to fine-tune it. For instance, lower the temperature by a degree or two if you prefer a cooler environment, or raise it if you prefer it to be slightly warmer. Continue making small adjustments until you find the temperature that provides the right balance of comfort and energy efficiency for you.

4. Consider External Factors
Take into account external factors that may influence the cooling needs of your space. For example, if it’s a particularly humid day, you may want to set the temperature slightly lower to help dehumidify the indoor air. Higher humidity levels can make the air feel warmer, so adjusting the temperature accordingly can help maintain comfort. Also, if the outdoor temperature is exceptionally hot, you might need to set the AC temperature a bit lower to compensate and ensure a comfortable indoor environment.
5. Utilize Programmable Features
Many modern AC systems come with programmable features that allow you to set different temperature levels for various times of the day. Take advantage of this functionality by programming the AC to adjust based on your daily routine. If you’re away from home during specific hours, you can raise the temperature during that time to save energy. Program the AC to lower the temperature shortly before you return so that the space is cool and comfortable when you arrive. Using programmable features helps you maintain comfort while maximizing energy efficiency.
Keep in mind that setting the AC temperature too low can result in unnecessary energy consumption and higher energy bills. This makes it crucial to find the balance between comfort and energy efficiency. Regularly evaluate and adjust the temperature settings based on factors such as personal comfort, energy costs, and external conditions to ensure an optimal cooling experience.

What are the benefits of using a programmable thermostat?
Programmable thermostats offer several benefits, such as energy savings by adjusting the temperature based on your schedule and reducing energy consumption when you’re away. It also provides increased comfort by setting the temperature to your liking in advance, as well as convenience, by automating temperature adjustments.
Can I install a thermostat myself?
The ease of installation depends on the type of thermostat and your existing wiring. Some thermostats, especially basic models, can be installed by homeowners with basic DIY skills. But more complex systems or smart thermostats may require professional installation to ensure compatibility and proper functioning.
Are there any maintenance tasks for thermostats?
Thermostats generally require minimal maintenance. But it’s a good idea to occasionally check and clean the thermostat’s components, such as removing dust from the sensors or changing the batteries if applicable.
Can a thermostat save energy and reduce utility bills?
Yes. Thermostats, particularly programmable and smart thermostats, can help save energy and reduce utility bills. By optimizing temperature settings based on your schedule and providing energy usage insights, these thermostats can help you manage and reduce energy consumption.
How do I know if my thermostat is not functioning properly?
Common signs of a malfunctioning thermostat include temperature inaccuracies, unresponsive controls, failure to turn on or off the heating or cooling system, or irregular cycling of the system. If you suspect your thermostat is not working properly, it may be helpful to consult the user manual or contact a professional for assistance.
