HVACDiagnostics & Troubleshooting4HighHVAC Technician$ implied

A newly installed R-454b HVAC system is overfeeding refrigerant due to a loose TXV, causing compressor noise and oil migration, and the technician is unsure whether to replace the TXV or try to migrate the oil back with hard cycles.

Existing diagnostic procedures for oil migration are unclear for new R-454b systems; no specific tool or guidance to differentiate between oil-induced false sensor readings and TXV malfunction.

App Concept

OilSnap Diagnostic & Recovery Guide

OilSnap is a mobile app that helps HVAC technicians quickly diagnose oil migration in new R-454b systems. It guides through step-by-step diagnostics, provides decision trees for TXV vs. oil issues, and suggests recovery procedures. It also logs data for future reference, reducing guesswork and callbacks.

Key Features

Interactive decision tree for oil migration vs TXV fault
Guided step-by-step recovery procedures (e.g., hard cycle timing)
Data logging of pressures, temperatures, and oil presence
Knowledge base for R-454b specific behaviors

Target Users: HVAC technicians and service companies installing and servicing R-454b systems, especially those new to the refrigerant.

Revenue Model: $14.99/mo per tech or $149/yr subscription
