Frequently Asked Questions

How often should I test my smoke detectors?

Most experts recommend testing smoke and CO detectors once a month to ensure they’re functioning properly.

How often should batteries be replaced?

For traditional smoke alarms, replace batteries at least once a year. Some units use long-life batteries (10-year sealed), but even those benefit from regular testing.

Do you install new smoke or CO detectors?

While this service focuses on testing and battery replacement, we can advise on placement and compatibility. We can also install new detectors if requested — just let us know.

Can you help with carbon monoxide detectors too?

Yes — we test and maintain both smoke and carbon monoxide alarms.

What if my detector keeps chirping?

A chirping detector usually means a low battery or end-of-life sensor. We’ll replace the battery and check the overall unit. If the unit itself is expired or malfunctioning, we can recommend a replacement.

Do you handle hard-wired detectors?

For hard-wired alarms with backup batteries, we can assist with battery replacement and basic testing. Electrical upgrades or rewiring should be done by a licensed electrician.
