I couldn’t tell you what I had for dinner last week, never mind when I last changed the thermostat batteries. And if we’re honest, most of us wouldn’t think to change them unless the thermostat suddenly fails.
If your A/C unit won’t turn on, your first instinct may be to call your favorite AC contractor, Ferrara’s Air. And while we would be more than happy to come out and troubleshoot your system, you may be able to save some money and time by first checking the batteries in your thermostat.
While not all thermostats use batteries, if you have a programmable thermostat, it likely runs on AA, AAA or 3V lithium batteries. When these batteries die, the thermostat loses any programmed settings and can cause the AC to fail. To prevent this, make a plan to change the batteries regularly before they die or worse begin to corrode.
To avoid any interruption in your AC’s operation, we recommend being proactive and changing the batteries in your thermostat at least once a year. This could be when you change your clocks for Daylight Savings time, or one a memorable anniversary date, or event during a scheduled maintenance. Ferrara’s Air, would be happy to change them for you during one of our bi-annual visits. Just remind the technician that you have new batteries you would like us to change for you.
Another helpful tip, when you change the batteries in your thermostat, it’s a good idea to replace them in your smoke detectors as well. No one likes that annoying siren going off in the middle of the night.
How to Replace Thermostat Batteries:
- Locate thermostat and remove the front plate. This may be snapped off or slid up and pulled off of the terminal screw blocks. This should expose the inner workings and the battery compartment.
- Check for and clear away any dust, cobwebs or debris.
- Using a fingernail or plastic lever, remove the batteries.
- Insert new batteries into the same location and in the same position as the old ones.
- Replace the cover of the thermostat and make any adjustments to the settings as needed.
Do not place any batteries that are leaking into the thermostat. These can damage the thermostat, or any other equipment they’re used in.
