When should routine inspections of the carbon monoxide levels in flue gas be conducted?

Routine inspections of carbon monoxide levels in flue gas should be conducted annually to ensure both safety and efficiency of the gas furnace. This frequency allows for timely detection of potential issues that could lead to unsafe conditions or decreased performance of the heating system.

Annual inspections align with standard safety practices in HVAC maintenance, where regular monitoring is vital in preventing carbon monoxide buildup, which can be hazardous to health. These inspections help in identifying any malfunctions or inefficiencies in the furnace that could contribute to improper combustion, leading to elevated carbon monoxide levels.

While more frequent inspections might seem beneficial, rigorous annual checks strike a balance between ensuring safety and being practical in terms of management for homeowners and technicians. This approach is often recommended by industry standards and local regulations, emphasizing the importance of maintaining safe operating conditions in residential heating systems.
