# HVAC Service Report: Window A/C Unit - No Cooling Responded to service call for window air conditioning unit over 10 years old blowing warm air instead of cooling. Upon inspection, accessed internal electrical components and wiring connections. Performed insulation resistance testing using megohmmeter to diagnose compressor and electrical system integrity. Testing revealed compromised compressor windings reading in the caution/bad range, indicating internal electrical failure typical of aged units. Explained findings and recommended unit replacement due to age and failed compressor component.

Responded to water leak in basement mechanical room caused by flue pipe installation that was routed above existing copper water line. Identified leaking T-junction with brass compression fittings on copper piping system where improper clearance during recent furnace installation created contact issue. Repositioned flue ductwork to maintain proper clearance from plumbing, repaired damaged compression fitting on water line, and verified all connections were secure with no active leaks upon completion.

Completed return ductwork installation for add-on air conditioning system in basement mechanical room.
