When it comes to setting the temperature of your air conditioner, it's essential to find the perfect balance between comfort and energy efficiency. Most people would likely feel comfortable with a slightly higher temperature than 72 degrees, such as 75 degrees. ENERGY STAR recommends 82 degrees while you sleep, but this may be too warm for many individuals. The National Sleep Foundation suggests that 60 to 67 degrees is a good temperature for sleeping, but this may be too cold for some and could increase your cooling bill. As an intermediate solution, more than 70 degrees is a good temperature to start with.
When you're trying to find the most reasonable configuration for your air conditioner, you have to begin somewhere and 78 degrees Fahrenheit is a great place to start. To maximize energy efficiency and comfort, it's important to adjust the temperature of your air conditioner according to the season. During the summer months, you can set your air conditioner to 78 degrees during the day and lower it to 72 degrees at night. During the winter months, you can set your air conditioner to 68 degrees during the day and lower it to 62 degrees at night. It's also important to remember that different rooms in your home may require different temperatures. For example, if you have a room that gets a lot of sun during the day, you may want to set the temperature higher than other rooms in your home.
Additionally, if you have a room that is rarely used, you may want to set the temperature lower than other rooms in your home. Finding the ideal temperature for your air conditioner can be a challenge, but with a little trial and error, you can find the perfect balance between comfort and energy efficiency.
