When you schedule a professional heating system service, a technician will thoroughly inspect your furnace or boiler, clean crucial parts like burners and heat exchangers, and test safety controls. They check for gas leaks, measure airflow, and verify carbon monoxide levels. Expect them to replace filters, lubricate moving components, and assess overall efficiency - usually taking one to three hours, depending on system complexity and maintenance history.
