Do Carbon Monoxide Detectors Expire?

Carbon monoxide (CO) detectors are essential safety devices that can save lives by alerting you to the presence of this deadly gas. But do CO detectors expire? The answer is yes, and it’s important to know when to replace them to ensure your continued safety.

How Long Do CO Detectors Last?

Most CO detectors have a lifespan of 5 to 7 years. This is due to the fact that the sensor inside the detector, which detects the presence of CO, can degrade over time. As a result, the detector may become less sensitive to CO and may not be able to alert you to the presence of dangerous levels of the gas. For best protection, replace your CO detectors every 5 years.

Factors That Can Affect the Lifespan of a CO Detector

• Environmental conditions: CO detectors can be affected by extreme temperatures, humidity, and dust. These conditions can cause the sensor to degrade more quickly, shortening the lifespan of the detector.
• Usage: If a CO detector is used frequently, it may need to be replaced more often. This is because the sensor can become worn out from repeated use.
• Power source: CO detectors can be powered by batteries or by a hardwired connection to your home’s electrical system. Battery-powered CO detectors will need to be replaced more often than hardwired detectors, as the batteries will eventually die.

Signs That Your CO Detector Is Expiring

There are a few signs that may indicate that your CO detector is expiring:

• The detector is beeping erratically. This could be a sign that the sensor is failing and the detector is no longer able to detect CO.
• The detector is not responding to test. When you test your CO detector, it should beep. If it does not beep, it may be a sign that the detector is not working properly and needs to be replaced.
• The display on the detector is dim or difficult to read. This could be a sign that the detector is losing power and needs to be replaced.

How to Replace a CO Detector

Replacing a CO detector is a simple process that can be done in a few minutes. Here are the steps:

1. Turn off the power to the detector. If the detector is hardwired, you will need to turn off the power at the circuit breaker panel.
2. Remove the old detector. Use a screwdriver to remove the screws that are holding the detector in place.
3. Disconnect the wires from the old detector. If the detector is hardwired, you will need to disconnect the wires from the terminals on the back of the detector.
4. Connect the wires to the new detector. If the detector is hardwired, you will need to connect the wires to the terminals on the back of the new detector.
5. Screw the new detector into place. Use a screwdriver to screw the new detector into place.
6. Turn on the power to the detector. If the detector is hardwired, you will need to turn on the power at the circuit breaker panel.
7. Test the new detector. Press the test button on the detector. The detector should beep.

Tips and Tricks

• Test your CO detector every month. This will help ensure that the detector is working properly.
• Replace the batteries in your CO detector every year. Even if the detector is hardwired, it is still important to replace the batteries every year.
• Never ignore a CO alarm. If your CO detector goes off, evacuate your home immediately and call 911.

Common Mistakes to Avoid

• Do not install CO detectors in the kitchen. CO detectors should be installed in bedrooms, hallways, and other living areas where people are likely to be exposed to CO.
• Do not install CO detectors too close to windows or doors. CO detectors should be installed at least 10 feet away from windows and doors.
• Do not paint over CO detectors. Paint can block the sensor and prevent the detector from working properly.
