Diagnosing intermittent low pressure lockout on a 5-year-old Rheem heat pump where the error code is misleading because suction pressure reads 111 psi despite low pressure switch being open.

Existing diagnostic tools do not provide a clear, real-time correlation between pressure readings and switch status, forcing technicians to rely on repeated cycling and guesswork.

App Concept

SmartDiagnose HVAC

SmartDiagnose HVAC is a mobile app that integrates with a Bluetooth-enabled manifold gauge and system controller to overlay real-time pressure, temperature, and switch status on a single timeline. It automatically captures fault codes and suggests likely root causes, eliminating the need to cycle the system multiple times.

Key Features

Real-time visualization of pressure, temperature, and switch status on a unified timeline
Automated capture and correlation of error codes with system parameters
Guided troubleshooting flow based on manufacturer-specific logic
Session recording for playback and remote sharing with senior techs

Target Users: HVAC service technicians at small to mid-sized residential and light commercial companies (1-50 techs) who diagnose intermittent system faults.

Revenue Model: $19.99/mo per technician subscription, or $199 annual subscription with a free tier limited to basic diagnostics
