Assessed overall system condition, noting typical operational wear on filter media and rooftop mounting surfaces. All HVAC components inspected and photographed for service records. System operational and ready for continued service.

Responded to service call for 3-year-old rooftop A/C unit experiencing loud knocking noise during operation while still providing adequate cooling. Accessed rooftop unit and performed diagnostic inspection to identify source of mechanical noise. System found to be operating under warranty coverage for both parts and labor.

Completed routine Air Care Maintenance on residential outdoor condensing unit. Performed comprehensive system inspection, verified operational status of compressor and condenser fan motor, checked refrigerant levels, and cleaned condenser coils. Unit found in good working condition with no immediate repairs needed.

Completed annual cooling maintenance on residential split system air conditioning unit. Performed comprehensive inspection of outdoor condensing unit, checking all electrical connections, capacitors, and refrigerant lines. Cleaned debris from unit base and surrounding area. Verified proper operation of condenser fan motor and compressor. Inspected copper line sets for signs of wear or damage, noting normal oxidation on exposed piping. Checked electrical wiring integrity and capacitor functionality. System operating within normal parameters upon completion of maintenance service.

Responded to service call for reported holes in HVAC system affecting a 12-year-old furnace located in basement. Upon inspection, identified compromised return ductwork with visible openings that were allowing unconditioned air infiltration and reducing system efficiency. Documented existing conditions showing exposed ductwork, insulation gaps, and areas requiring sealing to restore proper system operation and prevent energy loss.

Completed full HVAC system installation including 70,000 BTU furnace and 2.5-ton air conditioning unit in basement mechanical room with left-side configuration.
