Responded to no cooling call on 10-year-old rooftop unit accessed via third-floor fire escape hatch. Upon inspection, found unit would not power on due to failed control board and defective hard start capacitor. Evaluated electrical components including control module, run capacitor, and potential relay system. Documented existing conditions showing compromised wiring connections and aging capacitor assembly requiring replacement to restore system operation.

Completed comprehensive cooling system tune-up on residential AC unit located on side of home. Performed standard maintenance protocol including system inspection, electrical testing with clamp meter showing 20.00 amp draw, and identified heavily soiled return air filter requiring attention due to significant dust and debris accumulation across louvers. All measurements within normal operating parameters; recommended filter cleaning or replacement to maintain optimal airflow and system efficiency.

Upgraded zoning system by replacing single-stage zone control board with multistage board and installing new 12x20 zone damper with motor orientation on 12" side due to parts availability. Added freeze-stat and discharge air sensor to new zone board, configured staging based on percentage of zones calling, and wired W2 and ds/bk terminals (clipped R-DS jumper) to enable reduced blower speed during single-zone air conditioning calls for improved comfort and efficiency.

Completed comprehensive cooling system tune-up on outdoor condenser unit located on side of home. Performed standard maintenance protocol including inspection of compressor operation, refrigerant level verification, electrical connection testing, condenser coil cleaning, fan motor lubrication, and airflow assessment.
