When was the last time you tested your smoke and carbon monoxide (CO) detectors? If you had to think about it, you’re not alone. However, this small act of neglect could put your home and family at serious risk. Smoke and CO detectors are your first line of defense against fires and carbon monoxide leaks, and can only work if properly maintained. Here’s how to check them, and what could happen if you don’t.

“Many homeowners assume that if the little light is blinking, the detector is doing its job,” says Dan Lender, owner of Golden Rule Home Watch & Concierge. “But like any safety device, these units need regular attention to ensure they’ll actually perform when you need them.”

How Often Should You Test your Smoke and CO Detectors?

Most manufacturers and safety organizations recommend testing your smoke and CO detectors at least once a month. This ensures the batteries and internal components are functioning correctly. It’s as simple as pressing the “test” button and listening for the alarm sound. Loud and clear is what you want to hear.

In addition to monthly testing, you should replace the batteries every six months, or more frequently if your alarms begin to chirp. For added safety, schedule full detector replacements every 10 years for smoke detectors and every 5-7 years for CO detectors, even if they still appear to be working.

“A quick monthly test is one of the easiest habits you can build into your home maintenance routine,” Lender adds. “It takes less than a minute but could literally save your life.”

The Hidden Dangers of Skipping Maintenance

Neglecting to test your detectors can have dangerous—and sometimes deadly—consequences. A smoke detector with a dead battery or failed sensor won’t alert you to a fire until it’s too late. Similarly, a malfunctioning CO detector could allow invisible, odorless carbon monoxide to build up in your home, leading to serious health issues or even death.

According to the National Fire Protection Association, 3 out of 5 home fire deaths occur in homes without working smoke alarms. In many of these cases, the alarms were present, but had disconnected or dead batteries.

“People underestimate how quickly a fire or CO leak can escalate,” Lender says. “A non-functioning detector can make the difference between a close call and a catastrophe.”

Simple Steps to Keep your Detectors Reliable

Maintaining your detectors doesn’t require special tools or expertise—just consistency.

• Test monthly. Press the test button and confirm you hear the alarm
• Replace batteries twice a year. An easy reminder is to do it when you change your clocks for Daylight Saving Time
• Clean the sensors. Dust and debris can block sensors, so gently vacuum each unit’s exterior every few months
• Replace old detectors. Mark on each detector when it was installed, and follow manufacturer timelines for replacement.

“Your detectors are tiny guardians. They need a bit of care now and then, but in return, they protect what matters most,” Lender says.
