How we repair your Carbon Monoxide Detector
A carbon monoxide detector is a battery or hardwired alarm with an electrochemical sensor that sounds when it detects dangerous levels of carbon monoxide gas. A carbon monoxide detector uses sensors, a power source of batteries or low-voltage wiring, a control panel or app, and often a wireless connection. A technician checks power, wiring and transformers, sensors and network connections.

Alarm is sounding
- Likely causes
- Actual carbon monoxide from a fuel-burning appliance, a blocked flue, a car running in an attached garage, or a sensor near its end of life.
- What our technician checks
- The technician measures CO levels with a calibrated meter and inspects furnaces, water heaters, ranges and flues.
Chirping every minute
- Likely causes
- A low battery, or an end-of-life warning signaling that the sensor needs replacement.
- What our technician checks
- The battery is replaced and the manufacture date and end-of-life signal are checked.
Quick checks you can do safely
- If the alarm sounds, get everyone outside to fresh air and call emergency services.
- Press the test button monthly to confirm the horn works.
- Replace the battery if the unit chirps.
- Check the manufacture date on the back of the unit.
- Make sure an alarm is placed on every floor and near sleeping areas.
Safety first: Carbon monoxide is odorless and deadly, so never ignore or silence an alarm without first leaving the home and calling for help.
