HVAC Maintenance FAQ: What Should I Set My Thermostat to When I’m Away From Home?
Ask a question about thermostat settings or type it into Google and you’ll find that everyone seems to have a differing opinion about what temperature to set your thermostat to when you’re away from home. The correct answer may be different for every household as it depends on your preference, your goals, and your budget. But today, we want to help our customers and answer one of the most common HVAC maintenance questions: What should I set my thermostat to when I’m away from home?
Follow These Guidelines
The U.S. Department of Energy has published the following basic guideline to help homeowners breach this debate: As a general rule, set your thermostat as low as comfortably possible in the winter and as high as possible in the summer.
Here’s why that works: the narrower the gap between the temperature in your home and outside, the lower your energy bill will be. For example, if it’s a hot summer day and it’s 89 degrees outside, it requires much less energy for your HVAC system to cool your home to 80 degrees than to 66 degrees. However, because you want to prioritize your and your family’s comfort level, you should ask yourself: what’s the closest temperature I can set my thermostat to to match the outside temperature that won’t leave me too uncomfortable?
Save Yourself Money
The Department of Energy estimates that you can save as much as 10% on your heating and cooling bill each year simply by adjusting your thermostat 7-10 degrees for at least 8 hours a day. The smaller the differentiation between the temperature your thermostat’s set to and the outside air temperature, the less energy you’ll use and the more money you’ll save.
If you typically keep your thermostat at a comfortable 68 degrees during the summer, try gradually increasing the temperature to more closely match the temperature outside your home. As your environment changes, your comfort level will adjust.
Similarly, if you generally like to keep your home at 78 degrees during the winter, take it down a notch to 68-71 degrees to not only save money but also require less work of your HVAC system and will equate to less need for additional HVAC maintenance.
How Should I Set My Thermostat When I’m Away From Home?
Away from home for less than 4 hours
If you’ll only be away from your home for a couple of hours, there won’t be much of a benefit derived from adjusting your thermostat settings. The savings you see from doing so will be offset by the energy it takes to readjust the temperature back to normal when you return home.
Away for more than 4 hours
If you will be away from home for more than 4 hours, we recommend adjusting the thermostat 5 degrees higher in the summer or 5 degrees lower in the winter. This is a good idea for weekdays when the family is out at work and school.
The savings earned by adjusting your thermostat by more than 5 degrees again will be offset by returning the settings to normal when you come home.
Away for an extended period of time
If you are going away on vacation, we recommend adjusting your thermostat by about 7-10 degrees to conserve energy while you’re gone. There’s no use spending money on heating and cooling when nobody is home.
