Unable to determine if HVAC system airflow problem is due to undersized return or duct static pressure, causing diagnostic confusion.

Workarounds Described

• takes photos of static pressure readings to manually analyze
• uses probe in return and high side probe in high limit to measure static pressure

Implied Software Gaps

• Mobile app that guides static pressure measurement and automatically interprets results to differentiate undersized return vs. duct resistance
• Visual diagnostic tool that overlays pressure readings on system diagram to identify restriction location

StaticPressure Pro

A mobile app that takes static pressure measurements (return and supply) and instantly analyzes whether the issue is undersized ductwork, low airflow, or a restriction. It provides step-by-step diagnostic guidance and generates labeled diagrams for reports.
