When should a chimney be cleaned if it is used for gas appliances?

Chimneys serving gas appliances should generally be cleaned once a year to ensure safety and proper functioning. Even though gas appliances produce far less soot compared to wood-burning stoves, there can still be the accumulation of debris and potential issues like corrosion, creosote buildup, or blockages that may not be visible without inspection. Regular annual cleaning and inspection help maintain airflow efficiency and reduce the risk of carbon monoxide buildup, contributing to the safety of the appliance and home. It's also crucial to address any other maintenance or issues that may arise during use, which can be best monitored during these annual cleanings.
