Possible reasons for carbon monoxide alarm

  1. Defective Carbon monoxide detectors: it is one of the most common factors that can trigger an alarm. Often it happens that a device gets defective and the CO alarm goes off.
  2. Limited resources or lack of fresh air: if your house is tightly closed for cooling or heating it happens that unhealthy gases accumulate inside. If there are no sufficient sources of fresh air CO alarm will trigger.
  3. Gas appliances near windows or fresh air vents: another possible reason is gas appliances near doors, and windows that prevent fresh air from getting inside the house.
  4. Air leaks or ductwork damage: If ductwork gets damaged an air leak occurs which results in alarm triggers.
