How Often Should You Change Your Thermostat Batteries?

September 25, 2018 | Blog

When was the last time you checked your programmable thermostat? If it’s been a while, right now’s a good time to perform some well-needed thermostat maintenance. Part of that maintenance includes checking the batteries and changing them as needed.

Batteries help your programmable thermostat retain its settings in the event a power outage occurs. If your batteries run out of juice, you could lose those settings along with the ability to properly control your HVAC system. For these reasons, it’s important to know when it’s time to change your thermostat batteries.

During Every HVAC Check-Up

Annual HVAC system checkups offer a perfect opportunity to proactively conduct thermostat maintenance. If you want to be on the safe side, simply change your thermostat batteries every time you perform your annual checkup.

When the Low Battery Indicator Appears

When the batteries are nearly depleted, a low battery indicator will appear on your thermostat’s display. Some thermostats feature a light in lieu of an on-display indicator. At this point, your batteries may have another month or two of life remaining, making it a good time to change your batteries.

When the Display Goes Blank

If the display goes completely blank, that means your batteries are completely dead. A dead set of batteries will leave your programmable thermostat unusable, leaving you unable to control your HVAC system. You’ll also lose your thermostat’s pre-programmed settings. If you get this far, you’ll have no choice but to change the batteries.

Great company. Contacted my current AC company to check on my warranty before charging me anything. Saved me a bunch of money and headache if dealing with anything. Would definitely recommend them and use them again.
