Programmable thermostats are a helpful tool for maintaining a comfortable temperature in your home. If the battery is running low, however, your HVAC system won’t run well. Changing it is a regular part of maintenance, and doing so on a set schedule will help your air conditioner or furnace run at optimal capacity. Here’s some basic advice on how, when, and why to change your thermostat’s battery.

The Importance of Batteries

Your batteries do more for your thermostat than help it run; they also keep the settings under control during power outages. If it’s the middle of the winter and your furnace goes out, they will come to the rescue, keeping an even temperature until the power’s restored.

When the power is on, your batteries should be fully charged. This keeps your heating and cooling systems running smoothly and helps them maintain an optimum temperature level for a longer period of time. The less they’re overworked, the less energy they waste, and the more money you save on your monthly bills. Improved in-home comfort and a reduced carbon footprint can all be obtained by keeping the batteries at a full charge.

How to Change the Batteries

Programmable thermostats start displaying the low battery symbol about a month before they run out. If you notice this symbol, flashing, or beeping coming from your thermostat, it’s time for a change. Once they die, they’ll no longer control your HVAC system, leading to uncomfortable, uneven temperatures. 

To change the batteries, you’ll either need to remove the compartment or slide the thermostat out from its wall slot, depending on which model you have. Do this every six months to a year, depending on how often you use your heating and cooling systems.

If you notice the “low battery” symbol flashing before this, make sure you change them anyway. The quicker you change the batteries, the more likely it is the settings you chose will remain. If you wait too long, they could be lost, and you’ll find yourself reprogramming the system all over again.  With routine changes, your thermostat will always function well. 

If you want your HVAC system to work its best, always keep your thermostat batteries charged.
