I recently completed a summer maintenance job on an 8-year-old Lennox gas package unit. The job involved replacing the air filter, cleaning the condenser coil, and lubricating the fan motor. I also checked the electrical connections and tested the thermostat to ensure it was working properly. After completing the maintenance, I performed a thorough inspection of the unit to ensure it was operating at peak efficiency. I also provided the customer with a detailed report of the maintenance performed and any recommendations for future maintenance.
