Thermostat Health: When to Change the Batteries

Thermostat Health: When to Change the BatteriesIt’s a hot day in Peachtree City, and you’re dying to crank up the A/C. But something’s wrong. The thermostat’s not working. There’s no display, and it won’t respond to any of your commands! Is it broken? Do you need to have it replaced? No. You just forgot to change the battery. Here are some thermostat maintenance tips to keep it from happening again.

When to Replace Your Thermostat Battery

As a general rule of thumb, you should change the battery in your thermostat every year, whether it needs it or not. Batteries are cheap, and it’s better to remove a good one than keep a bad one around until it causes problems. Set a reminder on your calendar, and try to choose a day for it that’s easy for you to remember.

Of course, it’s still possible for your battery to wear out before your scheduled replacement date. Signs your thermostat’s battery are dying include a faded or blank display screen, and problems with your HVAC system heating or cooling as it should. Your thermostat may also have a low battery indicator light, which will tell you that the battery is dying and in need of replacement.

How to Replace Your Thermostat Battery

Replacing the battery is an essential part of thermostat maintenance. First, turn the unit off and remove it from the wall. It generally either pulls off or slides off. There may be a simple compartment for the batteries, or it may require a screwdriver. Also note whether your thermostat takes AA, AAA, or another kind of batteries, and how many. Be sure to have enough of the correct ones ready.

When you’ve replaced the batteries, put the cover back on and place the thermostat back on the wall. If you have trouble with it, you can always ask your HVAC technician when they come to give your system its annual tuneup (which is another necessity you should remember to mark on the calendar every year).
