HVAC Detective: Root Cause Finder

A mobile app that takes in refrigerant pressures, temperatures, superheat/subcooling, and duct static pressure to diagnose complex intermittent faults, restrictions, and airflow issues. It correlats data points in real time and provides actionable next steps, reducing guesswork for field technicians.

Key Features
  • Guided data entry for pressures, temps, and duct static
  • Automated diagnosis of restrictions, overcharge, and duct undersizing
  • Intermittent fault pattern analysis using time-stamped logs
  • Step-by-step repair recommendations with diagrams
Target Users: HVAC field technicians diagnosing intermittent faults, restrictions, and airflow issues in residential and light commercial systems
Revenue Model: SaaS subscription ($9.99/month or $99/year) with a free tier for basic diagnostics

Problem Reports (9)

HydroGuard Condensation Controller
Variable-speed air handlers are sweating profusely, causing mold and filling drain pans despite no clogs, cracks, or missing shields, likely due to fan speed dropping too low in dehumidification mode.
HVAC4HighField Technician
HVAC Diagnostic Pro
HVAC technician struggles with diagnosing and repairing a poorly installed ducted AC system where ductwork limitations prevent proper airflow and refrigerant charge issues cause compressor icing.
HVAC4HighField Technician
GeoTech Diagnostic Pro
Geothermal heat pump trips on high pressure alarm within seconds of startup despite proper airflow and waterflow, preventing diagnosis or operation.
HVAC4HighHVAC Technician
CapTube Diagnoser Pro
HVAC technician struggles to diagnose a capillary tube metering device issue causing high humidity, as refrigerant pressures behave abnormally and standard troubleshooting is inconclusive.
HVAC3MediumTechnician
HVAC Diagnostic Assistant
Residential HVAC system (Trane) cannot maintain temperature with inadequate performance despite replacing evaporator coil, TXV, filter dryer, and refrigerant.
HVAC4HighHVAC Technician
HeatPump Diagnostics AI
HVAC technician struggling to diagnose an intermittent fault in their own multi-zone Daikin heat pump system, with inconsistent superheat/subcooling, low cooling capacity, and icing only under certain operating conditions, despite standard troubleshooting steps.
HVAC4HighHVAC Technician
CoolCheck Pro
HVAC technician diagnosing a residential AC unit with erratic high side pressure and subcooling fluctuations, unable to determine root cause after standard checks.
HVAC3MediumField Technician
FCU Doctor
Aquastats on fan coil units in a university dorm are failing repeatedly, even after replacements, with no identified cause.
HVAC4HighMaintenance Technician
ValveSnap Diagnostic
A technician is unable to diagnose why the high side pressure doesn't rise despite valves being open, suspecting a restriction possibly from an over-tightened valve.
