Responded to service call for 11-year-old Carrier system with inadequate cooling in upstairs zone, where temperatures remained at 80-82°F despite operation. Accessed attic-mounted air handler and outdoor condensing unit for diagnostic evaluation. Connected manifold gauges to service ports and performed refrigerant pressure analysis on outdoor unit. Assessed system airflow, verified blower operation, and checked for potential refrigerant loss or restriction issues. Completed full system diagnostics to determine root cause of reduced cooling capacity and elevated indoor temperatures.

Responded to callback for 1-year-old Bryant system not cooling properly with house temperature at 81°F and Ecobee reporting system stuck at 45% cooling capacity for 4 hours. Customer reported whistling sound during operation with thermostat set to 73°F. Upon arrival, performed diagnostic evaluation of cooling system and verified operational parameters. Measured supply air temperature at 70.2°F and confirmed thermostat communication. System was successfully restored to proper cooling operation with temperature dropping as expected. Verified elimination of whistling noise and proper system cycling. Ecobee alerts resolved and system now maintaining setpoint correctly.

Completed HVAC system installation including air handler unit with 5KW heat kit, drain pan, and wet switch safety device.
