Carbon monoxide (CO) alarms are essential for protecting your household from a deadly, invisible gas. Regular maintenance ensures they function properly, reducing risks from malfunctions or false alarms. Here’s what you need to know:
- Monthly tasks: Test alarms, inspect their condition, and clean vents. Ensure they’re mounted correctly and unobstructed.
- Six-month/annual tasks: Replace batteries (or the entire unit if it has a sealed 10-year battery), clean sensors with compressed air, and check for corrosion in battery compartments.
- Replacement guidelines: CO alarms typically last 5–7 years, or up to 10 years for sealed models. Look for end-of-life signals like error codes or specific beeping patterns.
- Documentation: Maintain a log of all maintenance activities, including test results, battery changes, and replacements.
For Pittsburgh residents, compliance with Pennsylvania’s Carbon Monoxide Alarm Standards Act is critical. Landlords must ensure alarms are installed and operational at the start of every lease term. Professional services like Sherlock’s Locksmith can assist with proper installation and maintenance.
Stay vigilant – routine checks and timely replacements can save lives.
How To Do Carbon Monoxide Detector Maintenance
Monthly Maintenance Tasks
Staying on top of these monthly tasks ensures your carbon monoxide alarms are functioning correctly. A consistent routine – like checking alarms on the first Saturday of each month – can help you stay organized and maintain a safe home. These steps also set the stage for more thorough maintenance down the line.
Test the Alarm
Start by testing each carbon monoxide alarm to confirm it emits a loud, clear beeping sound that can be heard throughout your home. Press and hold the test button on each unit for about 3–5 seconds until the full alarm sequence activates. Be sure to notify everyone in the house before testing to avoid unnecessary panic.
If the alarm sounds weak or doesn’t go off at all, it could be a sign of a low battery or an internal problem. First, check the battery connections. If the issue persists, it may be time to replace the alarm altogether. Testing each alarm individually ensures every unit is working as intended.
Check Alarm Location and Condition
A quick visual inspection every month can reveal potential issues before they become serious. As R.S. Andrews advises:
"Perform a visual inspection of your CO detector at least once a month. Check the display panel for any error messages or indicators the battery needs replacing. Ensure that the detector’s vents are free from obstruction and that there are no signs of damage or tampering."
Verify that each alarm is securely mounted on the ceiling or high on the wall, positioned at least 15 feet – ideally 20 feet – away from fuel-burning appliances like stoves, furnaces, and water heaters. Avoid placing alarms behind curtains, furniture, or other barriers that could muffle the sound.
Inspect the display panel for error messages or low-battery warnings. Clean the exterior with a dry cloth to remove dust, and check the vents for any buildup of dirt or debris that might interfere with the alarm’s operation. Look for physical damage, such as cracks or corrosion, and watch for soot marks or stains on nearby walls, which could indicate a possible leak from an appliance. Address any visible issues immediately to ensure the alarm stays in working order.
Record Maintenance Activities
After completing your checks, document everything to keep track of your alarm’s performance over time. A detailed maintenance log is invaluable for monitoring the condition of your alarms and ensuring they meet safety standards. Include key details such as the date of each test, battery replacement dates, and the manufacture date of each device.
Maintaining these records serves multiple purposes. It helps you identify patterns, like recurring issues or alarms nearing the end of their lifespan, and provides proof of regular maintenance – useful during safety audits or insurance claims. Be sure to note any problems, such as weak sounds, error messages, or physical damage, along with the location of the affected alarm and any corrective actions taken.
Store your records in an easily accessible place, whether it’s a notebook, a smartphone app, or a computer file. This way, you’ll have all the information you need to address potential issues quickly and effectively.
6-Month and Annual Maintenance
Monthly checks are great for keeping your carbon monoxide alarm working, but deeper maintenance every six months to a year is key to ensuring it stays reliable over time. These periodic tasks go beyond the basics, helping to maintain the alarm’s long-term performance.
Replace Batteries
Swap out the batteries in your carbon monoxide alarm every six months, or as soon as the unit signals a low battery warning. Here’s how to do it:
- Find the model number on your alarm.
- Remove the alarm from its mounting plate by twisting it counterclockwise.
- Take out the old battery and replace it with a new one of the same type.
If your alarm has a sealed 10-year battery, you’ll need to replace the entire unit when the battery dies or the alarm reaches its end of life.
Clean Alarm Vents
Over time, dust and debris can build up on your alarm’s sensor, potentially affecting its accuracy or causing false alarms. To clean it properly:
- Turn off the power to the alarm.
- Follow the manufacturer’s instructions to remove the cover or faceplate and access the sensor area.
- Use compressed air to gently blow away dust. Hold the can upright and use short bursts to avoid damage .
- Wipe the exterior with a dry, soft microfiber cloth. For tougher spots, a slightly damp cloth can be used, but never moisten the sensor.
Avoid using liquid cleaners or anything abrasive, as these can permanently damage the unit. Once cleaned, reassemble the alarm, turn the power back on, and test it by pressing the test button.
Check for Corrosion
The battery compartment is another area that needs attention. Look for signs of corrosion or loose connections. ADT advises:
"Open the battery compartment and check for corrosion or loose contact".
Corrosion might appear as white, green, or blue residue on the terminals, while sticky or crusty deposits could indicate battery leakage. Lowitt Alarms highlights the importance of this step, asking:
"Is the wiring adequately connected, and is the battery free of corrosion and leakage?".
If you notice any leakage or corrosion, replace the affected equipment immediately. Even minor corrosion can interfere with your alarm’s performance.
Update Emergency Plans
Even the best-maintained alarm works better when paired with an updated emergency plan. Take time each year to review evacuation routes and ensure everyone in your household knows what to do in case of an emergency. Update emergency contacts as needed and keep a copy of the plan in an easy-to-find spot. Share it with anyone who might be in your home during an emergency.
When to Replace Your Alarm
Carbon monoxide alarms don’t last forever. Knowing when to replace yours could be the difference between effective protection and a false sense of security. Here’s how to tell when it’s time for a new alarm.
Warning Signs to Watch For
Carbon monoxide alarms are designed to let you know when something’s wrong, often through specific beeping patterns or error codes. Here’s what to look out for:
- Quick beeps every 30 seconds or five beeps per minute: These signals mean the alarm has reached the end of its life, even if it seems to be working fine .
- Digital error codes like "ERR" or "END": These appear on alarms with displays and mean it’s time for a replacement. Don’t ignore these warnings – they’re there to alert you before the alarm stops functioning entirely.
- Three beeps every few minutes: This could indicate a malfunction or internal error. Try resetting the unit by holding the test button for 10–15 seconds. If the beeping continues, replace the alarm.
- Failure during testing: If the alarm doesn’t sound when you press the test button – even after putting in fresh batteries and cleaning it – it’s time to replace it.
Here’s a quick reference guide:
| Beeping Pattern | What It Means | Action to Take |
|---|---|---|
| Quick beep every 30 seconds | End-of-life warning | Replace the entire unit |
| 5 beeps every minute | End-of-life warning | Replace the entire unit |
| 3 beeps every few minutes | Malfunction or error | Reset; replace if it continues |
| Continuous beeping after battery change | End-of-life warning | Replace the entire unit |
If you notice any of these signs, check the alarm’s age and follow the manufacturer’s replacement guidelines.
Age and Manufacturer Guidelines
Carbon monoxide alarms come with expiration dates, and they’re not just suggestions – they’re critical for safety. Most alarms need replacing every 5 to 7 years. Kidde, a leading manufacturer, recommends replacing carbon monoxide alarms every 7–10 years, depending on the model .
According to Kidde:
"Kidde recommends replacing smoke and heat alarms every 10 years, and replacing carbon monoxide and combination alarms every 7-10 (depending on your model) to benefit from the latest technology upgrades."
For alarms with 10-year sealed batteries, the replacement schedule is simpler. Massachusetts state guidelines explain:
"Newer CO alarms have a 10-year sealed battery that does not need changing. At 10 years, the entire device is replaced."
Even if the alarm seems fine, its sensors lose accuracy over time, which is why these timelines are so important. To check your alarm’s age, look for the manufacturing or expiration date on the back of the unit . If the date isn’t visible or has faded, it’s safer to replace the alarm.
Getting Professional Help
Sometimes, troubleshooting isn’t enough, and professional help becomes necessary. Studies show that 40% of residential carbon monoxide detectors fail under hazardous conditions, and 17% trigger false alarms.
Certified technicians can test your alarm’s performance using advanced tools and real carbon monoxide gas – something the test button alone can’t do. They’ll identify whether the issue is due to environmental factors, installation problems, or a failing unit.
For those in Pittsburgh, professional services can ensure your alarms are installed correctly, meet local safety standards, and are functioning as they should. Technicians can also recommend the best placement for new alarms and explain how to maintain your specific model.
Don’t wait until your alarm stops working completely. If it’s nearing the end of its lifespan or showing warning signs, a professional evaluation can give you peace of mind and keep your household safe.

Local Safety Code Requirements
Pittsburgh residents must comply with Pennsylvania’s Carbon Monoxide Alarm Standards Act (Act 121 of 2013). This law outlines specific requirements for residential buildings, multi-family dwellings, and rental properties. For example, multi-family homes must have approved carbon monoxide alarms installed near bedrooms and fuel-burning appliances, as stated in the Act.
An "approved carbon monoxide alarm" is defined by the Act as one that meets ANSI/UL2034 or ANSI/UL2075 standards. If you’re using a combined smoke and carbon monoxide alarm, it must comply with additional UL standards – ANSI/UL217 for smoke and ANSI/UL2034 for carbon monoxide, or ANSI/UL268 for smoke and ANSI/UL2075 for carbon monoxide. The term "installed" refers to alarms that are hardwired into the electrical system, directly plugged into an outlet (without an intervening switch, except for a circuit breaker), or properly mounted if battery-powered, following NFPA 720 guidelines.
Landlords also have specific responsibilities under Act 121 of 2013. They must ensure alarms are installed and fully operational at the start of every lease term, offering tenants an added layer of protection. While Pittsburgh doesn’t have additional municipal codes for carbon monoxide alarms, it’s generally recommended to install a detector on every level of your home – including the basement – and near each sleeping area.
To stay compliant, make alarm maintenance part of your regular routine. Keeping a detailed log of maintenance activities can be helpful during inspections or insurance reviews. By combining consistent upkeep with adherence to local codes, you can create a safer living environment for you and your family.
Conclusion
Keeping your carbon monoxide alarm in good working condition is a must for safeguarding against this invisible danger. As Mesa Alarm Systems explains:
