Dispatched for a no-heat concern. Upon arrival, the system was operating and providing heat as designed. A full system inspection was performed to identify any recent faults or conditions that could have caused the issue. During the inspection, the furnace control board was checked for stored fault codes. The most recent error code indicated a high-limit fault. This fault typically occurs when the furnace senses excessive heat, commonly due to restricted airflow, elevated supply air temperatures, or insufficient heat removal from the heat exchanger. At the time of today’s inspection, the blower motor was operating properly and airflow was within acceptable parameters. Supply air temperatures were measured and confirmed to be within the manufacturer’s recommended temperature rise range, indicating the system is currently operating safely and efficiently. No active faults were present during today’s visit. The system was left operating normally, and continued performance should be mon
