Should I Turn Off the A/C While I’m Gone?

How to Save Money Without Overworking Your HVAC System

As summer heats up, many homeowners ask the same question: Should I turn off the air conditioner while I'm away from home?

While it may seem like a good way to cut energy costs, turning your A/C completely off can actually backfire. Experts recommend setting your thermostat to a higher—but not off—temperature, typically around 78–85°F when you're away. Why? Because shutting the system down entirely can cause your HVAC to work overtime when you return, using more energy to cool the space back down. This is known as rebound cooling, and it puts unnecessary strain on your system—potentially leading to higher energy bills and more wear and tear.

Instead, use a programmable or smart thermostat to adjust the temperature automatically when you're not home. Even better, install a StatGuardPlus thermostat guard to prevent guests, tenants, or employees from overriding your energy-saving settings. It’s a simple way to maintain control, reduce costs, and avoid thermostat wars—all with no tiny keys to lose.

Quick Tips:

  • Set your thermostat to 78°F while home, 85°F while away

  • Avoid turning the A/C completely off

  • Use StatGuardPlus to keep temperature settings secure and consistent

  • Extend the life of your HVAC system and save money this summer!
