HVAC technician struggles to diagnose a capillary tube metering device issue causing high humidity, as refrigerant pressures behave abnormally and standard troubleshooting is inconclusive.

No purpose-built diagnostic tool that accurately identifies capillary tube clogs or restrictions without invasive disassembly, especially in R22 systems with non-standard pressures.

Workarounds Described

manual addition of refrigerant to observe pressure response
checking temperature drop across lines
visual inspection of coil and filter

Implied Software Gaps

Software that models capillary tube behavior and recommends diagnostics without adding refrigerant

App Concept

CapTube Diagnoser Pro

A handheld diagnostic device that attaches to the service ports and analyzes pressure, temperature, and flow dynamics to determine if a capillary tube is clogged or if other issues exist. It provides clear pass/fail results and recommended actions, replacing guesswork and manual calculations.

Key Features

Automated capillary tube restriction detection
Real-time pressure/temperature graphing
Built-in refrigerant database (R22, R410A, etc.)
Step-by-step troubleshooting guide

Target Users: HVAC technicians and service companies of all sizes

Revenue Model: $199 one-time device purchase plus $9.99/mo subscription for cloud diagnostics and database updates
