The short answer is that it depends. By leaving the AC running at a constant temperature, you could risk straining your system and you’ll increase your utility bill. However, doing this keeps your home at the temperature you’ve chosen so that you don’t come home to a boiling or freezing home. It also helps protect your homes interior by keeping the levels of dryness or humidity to a minimum. During the less extreme seasons of fall and spring, you can leave the system off while no one is home, saving money with little consequence to your interior. If you’re gone and you choose to leave the A/C running, we recommend leaving it at 78-80 degrees.

One the best and most modern options is to install a programmable thermostat that would allow you to set times for the AC to run. You could even set up the programs and adjust them remotely via your smart technology! If this is just a bit outside your budget, then here are few tips that are cost-effective and easy.

  • Keep your ceiling fans on 7 days a week, 24 hours a day, 365 days a year. This helps regulate air flow while also easing up the efforts made by your HVAC system, especially in the extreme seasons! Doing this, will also help your home’s interior, whether you’re there or not.
  • Keep up with routine maintenance on your HVAC system all year long. This may seem obvious, but it can be everything from changing your air filter and finding the temperature that suits everyone in the house, to calling your local HVAC professionals to come take a look at your system. Routine maintenance is essential to keeping your HVAC system operational and your home comfortable!
