How to Maintain Carbon Monoxide (CO) Detectors

Carbon monoxide detectors are essential for the safety of your home and family. They can save lives by detecting carbon monoxide gas before it becomes a problem. However, they must be properly maintained to function correctly. This blog post will discuss properly maintaining your carbon monoxide detectors so that you and your loved ones can stay safe!

What is Carbon Monoxide (CO)?

Carbon monoxide is a gas that is produced when certain materials burn. It is colourless, odourless, and tasteless, so it can be very difficult to detect without a carbon monoxide detector. When too much carbon monoxide builds up in an enclosed space, it can be harmful or even fatal to people and animals who breathe it in.

Why is it Important to Maintain Carbon Monoxide Detectors?

Since carbon monoxide is so difficult to detect, it is important to have a way to monitor the levels of gas in your home. Carbon monoxide detectors are designed to do just that. They will alarm if the level of carbon monoxide in the air reaches a certain level. This will give you time to get fresh air and seek medical help, if necessary.

Do CO Alarms Operate Differently Than Smoke Alarms?

CO and smoke alarms are designed to protect homeowners from fire and carbon monoxide poisoning. However, there are some important differences between the two types of alarms. Smoke alarms detect smoke particles in the air, while CO alarms use sensors to detect carbon monoxide gas. Because smoke is more likely present during a fire, smoke alarms are typically more sensitive than CO. As a result, smoke alarms will usually sound an alarm before a CO alarm. However, both alarms should be tested regularly to ensure they work properly.

Maintaining your carbon monoxide detectors is important for the safety of your home and family. Here are some tips on how to properly maintain your carbon monoxide detectors:

1. Replace Batteries Regularly

Any detector that is either battery-powered or plugged into an outlet should be checked regularly, preferably monthly. This is especially important in winter when the risk of fires and carbon monoxide poisoning increases. By keeping track of when you changed the batteries in your detectors, you can be sure they will have an adequate power supply throughout the season.

It may be too late if you wait for the detectors to chirp. In addition, carbon monoxide detectors should be replaced every five years to ensure they are functioning properly. By taking these simple steps, you can help keep your family safe from harm.

2. Test Your Carbon Monoxide Detectors

It’s important to have a carbon monoxide detector in your home and to test it regularly to ensure it’s working correctly. The easiest way to test a carbon monoxide detector is to use an aerosol can of compressed air. Hold the test button on the detector and spray a short burst of air into the unit. If the detector is working properly, it will sound an alarm.

3. Keep Carbon Monoxide Detectors Clean

Unfortunately, carbon monoxide poisoning is a leading cause of accidental death in the United States. That’s why it’s so important to have working carbon monoxide detectors in your home. But detectors are only effective if they’re properly maintained.

To ensure that your detectors are working properly, keep them clean and free of dust and cobwebs. This will help them work more efficiently and last longer. If you don’t already have carbon monoxide detectors in your home, now is the time to get them. And be sure to follow the manufacturer’s instructions for proper maintenance.

4. Replace Old Units

The average carbon monoxide detector will start to degrade after around five years, and it may not be as effective at detecting the gas. That’s why replacing your detector every five years is important to ensure you’re always protected. So if you’ve got a detector that’s five years old or more, now is the time to buy a new one. Choose a model from a reputable brand and ensure it meets all the latest safety standards.

5. Make Sure Your Detectors Are In The Right Location

According to the CDC, exposure to carbon monoxide can cause headaches, dizziness, nausea, and even death. That’s why it’s so important to have working carbon monoxide detectors in your home. But where should you place them? The answer depends on the layout of your home and the type of detectors you have.

If you have battery-operated detectors, they should be placed near the ceiling in every room. For hardwired detectors, the best location is near the home’s sleeping areas. And for homes with multiple floors, carbon monoxide detectors should be placed on each level. These simple steps can help protect yourself and your family from the dangers of carbon monoxide poisoning.

    6. Do Not Paint Over Carbon Monoxide Detectors

    Many homeowners take pride in maintaining a tidy and well-decorated home. When it comes to home improvement projects, painting is often one of the first tasks that come to mind. However, exercising caution when painting around carbon monoxide detectors is important. Carbon monoxide is a colourless and odourless gas that can be deadly if inhaled in large quantities.

    Although detectors are designed to sound an alarm if high levels of carbon monoxide are detected, painting over them can impede their ability to function properly. If you must paint near a carbon monoxide detector, remove the detector from its mount and cover the sensor with tape. Once the paint has dried, re-attach the detector and test it to ensure it is functioning properly.

    7. Add More Units

    You should have at least one carbon monoxide detector on each home floor and inside any bedrooms with gas appliances for maximum protection. You should also have a detector immediately outside each bedroom so that you can be alerted even if you are asleep.

    8. Do Not Disable Carbon Monoxide Detectors

    Do not disable carbon monoxide detectors, even when going off frequently. If your carbon monoxide detector is going off frequently, it indicates that there may be a problem, and you should have it checked out by a professional.


    While carbon monoxide detectors are important in keeping your family safe, they must be properly maintained to work effectively. Keep your detectors clean, replace them every five years, and never paint over them. You should also have at least one detector on each floor of your home and inside any bedrooms with gas appliances. By following these simple tips, you can help keep your family safe from the dangers of carbon monoxide poisoning.
