Replaced failed blower motor assembly (CFM) on outdoor condensing unit. Removed old blower wheel and motor showing significant dust accumulation, installed new assembly, and verified proper operation. Old components disposed of per protocol.

Responded to water leak complaint from indoor air handler unit. Upon arrival, found condensate drain line clogged, causing water to back up and overflow into collection bucket when system operates. Cleared obstruction from drain line, verified proper drainage flow, tested system operation, and confirmed no further leakage occurring.

Responded to service call for intermittent unit shutdown due to moisture sensor alerts in drain pan on recently installed system. Accessed crawlspace air handler with ladder and inspected condensate drain system and safety float switch. Verified control board connections and sensor wiring at air handler control panel. Brought replacement backup sensor as requested and completed system diagnostic to resolve false moisture detection causing premature shutdowns.

Responded to no cooling complaint on older outdoor AC unit servicing unit #832, located at side of building #830. Upon arrival, found unit off with only fan operating. Connected refrigerant manifold gauges to diagnose system, revealing abnormal pressure and temperature readings indicating potential refrigerant issue or system malfunction. Observed heavily soiled condenser coil with significant dirt and debris accumulation between fins, restricting airflow and reducing heat transfer efficiency, which would contribute to reduced cooling capacity and system performance issues.

Responded to no cooling call on unit over 10 years old located on side of home. Upon arrival, inspected outdoor electrical disconnect and found compromised wiring connections at junction box with deteriorated stucco around mounting area creating potential safety concern. Documented electrical components and exterior wall condition with photos for customer records and recommended follow-up repairs to ensure safe system operation.
