Dispatched to perform a routine annual furnace maintenance on a one-year-old system. Upon arrival, a full system inspection and performance evaluation was completed. The furnace was inspected for proper operation, safe ignition, and correct airflow. All electrical connections were checked and found to be secure, and the system cycled normally in heating mode. The UV-C germicidal system was inspected and confirmed to be operating properly to help reduce airborne contaminants and improve indoor air quality. The whole-home dehumidifier was also inspected, with controls and operation verified for proper functionality. Airflow and duct performance were evaluated. The home’s ductwork has been professionally sealed using AeroSeal, and no visible air leakage concerns were noted at this time. This sealing continues to support efficient airflow, improved comfort, and reduced energy loss. Temperature rise and system performance were within manufacturer specifications. No immediate repairs were
