One question we often hear is why do thermostats have batteries? Baggett Heating and Cooling is here to tell you why digital and hardwired thermostats still need to run on batteries and what to do when they are low.
Most digital thermostats are both hardwired to your house and have backup batteries. The reason for having backup batteries is to save any programmed information.
Knowing what to expect when batteries are low or changing them annually can help you take care of your HVAC system. Knowing whether or not your thermostat has batteries or not could also save you time and money instead of noticing that your thermostat is dead and having to call us to come to take a look instead of replacing the batteries on your own first.
How do I know when to change the batteries?
- Some thermostats will flash a low battery message on the screen.
- If your thermostat screen is blank or unresponsive.
Changing batteries
- It’s recommended that you change out your batteries at least once a year.
- Check the user’s manual for instructions on how to change the batteries, or look for a button or area on your thermostat case to access the compartment where the batteries are.
- If you’re unable to locate a battery compartment, this could mean your type of thermostat does not have backup batteries.
- Call Baggett to replace your thermostat with one that has backup batteries.
If you replace your batteries and you notice your HVAC system isn’t working correctly, this may mean you have more significant problems than just a dead battery. Baggett recommends having regular maintenance performed on your HVAC system. Learn more about routine maintenance and join Baggett’s Preferred Customer Maintenance Club.
