Responded to callback for frozen evaporator coil on HVAC system that was previously repaired. Upon arrival, confirmed unit had been shut off by customer to allow ice buildup to thaw. Inspected air handler unit in attic space, examined refrigerant lines, ductwork connections, and system components for underlying cause of freeze condition. Documented equipment condition with photos showing existing installation, copper line set, flexible ductwork, and cabinet assembly to verify proper thaw-out and assess system for airflow restrictions or refrigerant issues requiring further attention.

Responded to basement drainage issue where standing water was holding in a 2-foot drainage well accompanied by sewer gas odor. Upon inspection, found circular floor drain with heavily corroded metal rim and standing water in the basin. Assessed drainage system including adjacent rectangular grate drain. Documented existing conditions showing extensive rust on drain components, deteriorated concrete flooring with multiple cracks, and evidence of prolonged moisture exposure. Identified drainage well not actively backing up but failing to properly evacuate water, allowing sewer gases to escape into the basement area.

Completed preventive maintenance tune-up on residential air conditioning system located in side yard. Performed standard inspection of outdoor condensing unit, checked refrigerant levels, cleaned condenser coils, verified electrical connections, and tested system operation. Indoor furnace unit inspected for proper airflow and drainage, with all components found to be operating within normal parameters.

Responded to no cooling complaint on one of two systems at the property. Replaced failed thermostatic expansion valve (TXV) and installed hockey puck style wet switch for secondary drain line protection. System tested and verified operational upon completion, with proper refrigerant pressures confirmed using digital manifold gauges. Defective parts removed and disposed of per protocol.

Responded to service call for continuous fluttering noise coming from attic-mounted cooling system on unit less than 10 years old. Accessed attic space to inspect equipment and diagnose source of noise issue. Documented attic access point and return air vent configuration for service records.

Responded to no cooling call on 5-year-old Lennox system affecting upstairs zone. Unit had ceased operation following recent service visit. Upon inspection, discovered condensate drain line obstruction in attic space causing secondary float switch activation and system lockout. Cleared blockage from PVC drain assembly, verified proper drainage flow, and tested float switch operation. System restored to normal cooling operation with all safety devices functioning correctly.

Responded to service call for dual-zone cooling system not maintaining set temperature. Upon arrival, performed diagnostic evaluation of both attic-mounted units using refrigerant manifold gauges to measure system pressures and temperatures. Readings indicated potential refrigerant charge issues or system performance deficiencies requiring further assessment and repair recommendations.

Responded to no cooling complaint on Carrier system. Upon arrival, performed diagnostic evaluation of indoor furnace unit and outdoor condensing unit. Inspected system components, verified refrigerant levels, and assessed overall equipment operation to identify cause of inadequate cooling performance.
