You’re right — it’s important to change your smoke detectors regularly to keep your home safe. Here’s a quick guide:
When to Change Your Smoke Detectors
- Replace the whole unit every 10 years (check the manufacture date on the back).
- Change the batteries once a year, unless you have a unit with a 10-year sealed battery.
- Test them monthly to ensure they’re working properly.
Signs It’s Time for a Replacement
- Chirping sounds even after battery replacement.
- Yellowing of the plastic casing (a sign of age).
- It doesn’t respond when tested.
