Performed thorough inspection of condenser unit electrical components including capacitor, contactor, and associated wiring connections; verified proper operation and secured all electrical connections. Inspected thermostat controls and confirmed proper communication between control system and equipment for accurate temperature regulation and system cycling.

Provided estimate for replacement of two existing Carrier outdoor condensing units serving residential property. One unit approximately 12 years old and second unit 25-30 years old both requiring replacement. Existing 9-year-old Carrier furnace with connected evaporator coil to remain in service. Both outdoor units have standard accessibility for replacement. Measured existing equipment dimensions and documented current system configuration in basement mechanical room including furnace, ductwork, and connected components.

Returned to property to complete installation of Honeywell gas control valve on water heater. Successfully installed replacement valve, restored gas supply, and lit pilot following proper safety procedures. Verified unit achieved proper combustion with stable blue flame pattern visible through viewing port and confirmed water heater returned to normal operation with temperature controls functioning correctly.

Completed HVAC maintenance agreement inspection on outdoor condensing unit, model 4710E01260, 208-230V system. Performed temperature diagnostics using digital thermometer at supply grille, recording 188.8°F reading.
