# HVAC Service Call - No Cooling Condition Responded to a no cooling complaint on a residential property with two AC units. The non-operational unit was over ten years old and readily accessible at ground level, requiring no ladder work for service access. Upon arrival, performed complete system diagnostics using manifold gauges and digital testing equipment to assess refrigerant pressures, temperatures, and overall system performance. Initial inspection revealed the affected unit was not providing adequate cooling to the designated zone. Conducted thorough examination of the outdoor condensing unit, checking electrical connections, contactor operation, and compressor function. Verified proper voltage supply and amperage draw on all major components. Inspected the condenser coil for airflow restrictions, debris buildup, or damage that could impair heat rejection capacity. Evaluated the evaporator coil assembly, which showed typical wear patterns consistent with a unit of this age.
