HVACDiagnostics & Troubleshooting3MediumTechnician$ implied

Difficulty diagnosing intermittent cooling failure caused by a faulty TXV, leading to uncertainty in repair decisions.

No software tool exists to dynamically interpret fluctuating superheat/subcool data and equalization time to confirm TXV failure; technician relies on manual observation and experience.

Workarounds Described

manually heating sensing bulb to test TXV operation
observing pressure equalization time manually
relying on auditory cues (hissing) to assess TXV condition

Implied Software Gaps

Automated TXV response test using temperature simulation
Pressure equalization timer with automatic recording
Sound level analysis module for detecting abnormal valve noises

App Concept

ValveCheck Pro

A mobile app that guides HVAC technicians through TXV diagnostics by analyzing real-time pressure, temperature, and equalization data. It overlays expected ranges and suggests failure modes, reducing diagnostic time and uncertainty.

Key Features

Real-time pressure/temperature data import from gauges
Automated superheat/subcool trend analysis
Equalization time calculator with baseline comparison
Step-by-step diagnostic workflow for TXV issues

Target Users: HVAC technicians and service companies in residential and light commercial markets (1-20 trucks)

Revenue Model: $19.99/mo per technician subscription, or $199/yr
