Responded to cooling complaint with 12-degree temperature differential between setpoint and actual indoor temperature. Performed diagnostic evaluation on 25+ year old split system with outdoor condensing unit and indoor furnace/air handler located in kitchen closet. Upon inspection, documented equipment age, configuration, and current operating conditions. Provided diagnostic findings and presented repair options to address inadequate cooling performance.

Responded to no-cooling call on 5-8 year old residential air conditioning system. Upon arrival, found unit running continuously in Stage 2 with compressor not engaging, resulting in room-temperature air discharge. Diagnosed failed dual-run capacitor preventing compressor operation. Replaced defective Genteq capacitor (7.5µF, 370V) with new OEM-equivalent component, restoring proper compressor function and cooling capacity. System tested successfully with normal amperage draw and temperature differential achieved.

Performed comprehensive assessment of 18-year-old 5-ton commercial HVAC system experiencing complete failure. Unit found to be non-operational with severely deteriorated condenser coil fins showing extensive corrosion throughout. Documented electrical panel configuration and existing furnace installation with associated ductwork and venting systems. Provided estimate for complete system replacement due to age of equipment and extent of component degradation making repair economically unfeasible.
