I arrived at the client's home and performed a thorough gas furnace maintenance checklist. I checked the gas pressure, inspected the burners, cleaned the filters, and tested the thermostat. I also checked the electrical connections and ensured that the unit was operating safely and efficiently. After completing the checklist, I provided the client with a detailed report and recommendations for any necessary repairs or maintenance. The client was very satisfied with the service and thanked me for my professionalism and attention to detail.
