In general, a carbon monoxide detector should be installed at room temperature. This will ensure it does not get impacted by a sudden drop in temperature.

However, in some parts of the home, the temperature can drop during the night. This leads to a situation where the carbon monoxide detector goes off in the middle of the night.

If a carbon monoxide detector goes off at night, you will want to make sure it’s not alerting you about a potential leak.

If this is a constant issue then you can begin to troubleshoot the problem to figure out what is causing the false alarm.

For the most part, the issue is going to have to do with the battery.

3. Low Temperature

This is one of those situations that can happen when the carbon monoxide detector is set up in a room that is not kept warm.

During the day, the temperature is going to remain high, which means it is unlikely to trigger the carbon monoxide detector.

However, when the sun goes down, this is when the temperature drops rapidly.

If it is located in a colder part of the house, the sudden drop in temperature might cause the detector to start beeping.
