View allHVAC Detective: Root Cause Finder
An app that integrates refrigerant circuit data and duct pressure readings to pinpoint the root cause of intermittent faults and installation errors, with step-by-step troubleshooting guidance.
“Technician lacks documentation on the two-wire green plug for LG Multi V system and cannot get the service tool to connect to AHU kits with ACM75139001 comm modules, making it difficult to trace and name indoor units.”
“Apprentice refrigeration technician struggles to diagnose a multi-split system fault where wiring and refrigerant piping may be mismatched, causing inconsistent operation and high-pressure protection.”
PipeSleuth - Noise & Leak Finder
An app that helps homeowners and plumbers diagnose intermittent plumbing noises and leaks by capturing and analyzing sound & moisture patterns over time. It identifies root causes like faulty PRVs, condensation leaks, and flange issues.
“A newer plumber struggles to diagnose the source of ceiling stains when no active leak is found, leading to cutting open ceilings unnecessarily and uncertainty about the correct explanation for customers.”
“Unable to identify and fix a recurring banging noise in condo walls caused by plumbing, disrupting sleep for months.”
ArcSnap Tracer
Electricians struggle with intermittent arc faults that don't trigger during testing, and circuit tracing in messy panels when ohming out is not feasible. This app provides a portable diagnostic tool that captures arc fault signals over time and enables circuit tracing without ohming out.
“An electrician needs to trace and document complex, code-violating multi-wire branch circuits with shared neutrals across multiple conduits and junction boxes in a health facility.”
“Electricians hate the new style of meter socket that requires removing the meter to check voltage, making routine electrical testing difficult and dangerous.”
ABS ProGuide
Mechanics struggle to diagnose and fix ABS sensor and circuit issues due to lack of specialized, step-by-step guidance and integrated diagnostic tools. An app that provides vehicle-specific ABS diagnostic procedures, wiring diagrams, and repair instructions would fill this gap.
“Touchless self-service car washes fail to clean effectively, requiring manual hand washing.”
“Needs a home-use scan tool that can diagnose ABS systems, run advanced diagnostics, and perform brake service on newer Chevrolet vehicles without breaking the bank.”
CompHealth Diagnostic Assistant
Field technicians lack tools to combine electrical and refrigeration data for accurate fault isolation. An app that guides step-by-step measurement interpretation can reduce guesswork.
“Unable to determine if HVAC system airflow problem is due to undersized return or duct static pressure, causing diagnostic confusion.”
“HVAC technician struggles to diagnose and fix intermittent LG VRF CH150 alarm caused by a leaking indoor unit EEV, with negative subcooling indicating refrigerant bypass.”
PumpTroubleShoot Pro
Homeowners and technicians struggle to diagnose well pump cycling and recirculation pump air locks due to lack of step-by-step guidance. This app provides interactive troubleshooting for pump systems.
“Intermittent water heater relief valve discharge at night causing water damage to neighbor's unit, with suspected building pressure spikes that cannot be diagnosed due to restricted access to common mechanical areas.”
“Plumbers recommending expensive excavation or hydro-jetting without first performing a simple snake to check for a main sewer line blockage.”
Individual Problems
