What to Set Your Thermostat to When Away

October 18, 2022

From a tropical vacation or a long trip for work, leaving home means making preparations for your heating and cooling system. You won’t be using it as long as you’re away, so you can make adjustments as necessary to conserve your energy use. At the same time, you shouldn't just turn it off for the entire duration of your trip.

For the most part, it’s better to leave your HVAC system going and just make adjustments depending on whether it's winter or summer. That way you can lower energy costs without having to worry about coming back to an uncomfortable home. We’ll explain why you should avoid turning your HVAC system off as well as the most energy-efficient thermostat settings for different times of year.

Here’s Why You Shouldn’t Leave Your Thermostat on Hold

While you may be inclined to turn your HVAC system off before a trip, this can end up stirring up big problems by the time you return. This is particularly true when the weather will be severely hot or cold while you’re away from home.

As an example, shutting the HVAC system down during the summer could produce very high humidity. Not only will your home feel gross when you have returned, but it may have also invited mold/mildew growth or pest infestations.

And during the winter, leaving the furnace off can lead to pipes freezing or even bursting. It’s an awful feeling to come home from a nice trip only to discover substantial water damage near a broken pipe.

Best Thermostat Settings While at Work

You can optimize the temperature even when you're just going to work. Considering you’re out of the house for 8 hours or more, it doesn’t seem sensible to keep an empty home heated or cooled as if you were there. As a general rule, it’s recommended to raise the thermostat by 5 degrees or so. Meaning that if you prefer a comfortable 72 degrees, try increasing it to 76-77 while you’re at work.

But you can save even more if you're open to further adjusting the temperature. As reported by the Department of Energy, you might save nearly 10% on your HVAC expenses by making an adjustment of 7-10 degrees.

Energy-Efficient Thermostat Settings While Away from Home in Summer

If you're on an extended trip in the middle of summer, you can make bigger adjustments. This prevents wasting energy while still defending your home from the hassles that come with leaving it without air conditioning. About 5 degrees is suitable for shorter trips while around 10 degrees is worthwhile if you’ll be away from home for 2 weeks or longer. If you prefer keeping the house at 72 in the summer, 78-82 will offer great results.

Best Thermostat Settings While On a Trip in Winter

To try and find the most energy-efficient thermostat setting for a winter getaway, just lower the temperature by the same amount you would increase it in summer. 68 is a common winter thermostat setting, so adjusting to 63-58 will keep your plumbing safe while restricting how often your furnace runs.
