How Smart Thermostats Handle Vacation and Away Modes

September 28, 2026

Making the Most of Vacation Mode Features

When you're heading out of town, your smart thermostat's vacation or away mode feature can help reduce unnecessary energy use while you're gone. Old Glory Air Conditioning and Heating explains how these features typically work and how to use them effectively.

What Vacation Mode Generally Does

Vacation mode typically adjusts your thermostat to a more energy-efficient temperature setting for the duration of your trip, reducing cooling or heating demand in an unoccupied home without needing you to manually remember to adjust settings before leaving.

Setting Appropriate Away Temperatures

Most systems allow you to customize your vacation temperature settings, and choosing a moderate setting, rather than an extreme one, helps balance energy savings with avoiding excessive strain when your system needs to return to a comfortable temperature upon your return.

Scheduling Your Return Temperature in Advance

Many smart thermostats allow you to schedule your home to return to a comfortable temperature before you actually arrive back, so you're not walking into an uncomfortably warm or cold house after your trip.

Considering Humidity and Pet Needs While Away

If you have pets staying home during your trip, or if humidity control remains important even during vacation mode, adjusting your settings to account for these factors rather than using the most extreme energy-saving setting available is worth considering.

Using Geofencing as an Alternative to Manual Activation

Some smart thermostats use geofencing to automatically detect when you've left the general vicinity of your home, activating away settings without requiring you to remember to manually enable vacation mode before departing.

Monitoring Your Home Remotely While Away

Many smart thermostats allow remote monitoring, so you can check in on your home's temperature and humidity levels during an extended trip, providing peace of mind and the ability to make adjustments if needed.

Considering Extended Absences vs. Short Trips

For very short trips, the energy savings from activating vacation mode may be modest, while extended absences, such as weeks-long trips, often provide more meaningful savings from consistent away-mode settings throughout the trip.

What Happens If Your Home Loses Power While Away

It's worth understanding how your specific smart thermostat behaves following a power interruption during your absence, since settings may reset depending on the device and backup power configuration.

Getting the Most from This Feature Long-Term

Regularly using vacation mode for trips, rather than forgetting to activate it, helps ensure you're consistently capturing the potential energy savings this feature is designed to provide over time.
