# Large HVAC Installation - Attic Ductwork Assessment and Correction Plan Conducted comprehensive evaluation of newly installed HVAC ductwork system in residential attic space. Inspection revealed multiple deficiencies requiring immediate attention to ensure proper system performance and efficiency. ## Primary Issues Identified **Airflow Restrictions:** Discovered flexible ductwork installed with excessive kinking and compression throughout attic space. Multiple duct runs improperly routed, creating sharp bends and restrictions that significantly impede airflow and reduce system capacity. Documented improper installation techniques affecting overall HVAC performance. **Return Air Leakage:** Identified unsealed return air collars at multiple connection points. Gaps at collar interfaces allowing hot attic air infiltration into return air stream, compromising system efficiency and indoor air quality. This condition forces system to condition unconditioned attic air, increasing energy

Cycled system on to verify unit came back online and resumed normal cooling operation. Left work area clean and advised proper system function restored.

Installed four 10-inch flexible ducts and one 12-inch flexible duct in attic space, connecting to existing HVAC air handler unit. Addressed critical deficiency by fabricating and installing sheet metal piece to seal gap exceeding 1 inch wide where evaporator coil connects to plenum, preventing hot air infiltration that was compromising system cooling efficiency. Secured sheet metal with screws and properly sealed all connections to eliminate air leakage. Removed plastic material obstructing furnace vent pipe and trimmed combustible materials to establish required 1-inch minimum clearance from gas furnace flue pipe per code requirements. Verified refrigerant charge and system pressures, confirming proper levels. Tested complete HVAC system operation to ensure adequate cooling performance and proper functionality following repairs.

Replaced both control boards at the outdoor condensing unit to restore proper system operation. Verified all electrical connections, tested system functionality, and confirmed unit is operating within manufacturer specifications.

Technician responded to complete annual cooling maintenance on residential AC system as follow-up to previous service visit. Due to inclement weather conditions, maintenance procedure was partially completed. Full system inspection was performed as requested, and outdoor condensing unit was assessed. Technician will schedule return visit to complete refrigerant charge verification and finalize maintenance protocol.

Responded to callback for AC unit freezing up after previous blower motor service. Upon arrival, unit was off per customer request. Performed thorough inspection of the system including blower assembly, metering device, and refrigerant lines. Previous technician had identified and corrected a gap in the blower assembly that was pulling hot air, but unit continued to freeze. Evaluated airflow, checked for restrictions, and inspected the metering device for potential malfunction as previously suspected. Documented current system condition with photos of crawlspace installation and equipment location for reference.
