I conducted a comprehensive diagnostic on a Lennox gas propane system, ensuring optimal performance and efficiency. The process began with a thorough visual inspection of the unit, checking for any visible signs of wear, damage, or leaks. I then proceeded to test the ignition system, verifying that the pilot light and burners ignited properly. Next, I measured the gas flow and pressure to ensure they were within the manufacturer's specifications. Additionally, I assessed the thermostat functionality and checked the air intake and exhaust systems for blockages or obstructions. Finally, I performed a safety check on the carbon monoxide detector and verified that all safety mechanisms were functioning correctly. The system was cleaned and lubricated as needed, and I provided the customer with a detailed report of the findings and recommendations for maintenance.
