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.”
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.
“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.”
“Unable to determine if HVAC system airflow problem is due to undersized return or duct static pressure, causing diagnostic confusion.”
SpikeSnap HVAC Diagnostics
An app that captures and correlates transient sensor data to pinpoint intermittent failures in HVAC systems, solving the gap in diagnosing random, short-duration spikes that standard tools miss.
“Universal condenser fan motor gets stuck in programming mode, with no clear cause despite replacing surge protector and motor, causing repeat service visits and customer downtime.”
“SystemVu software shows 'cooling prevented' with no clear alarms, and VFD communication faults persist despite bypassing VFD hardware, leaving technician unable to diagnose root cause.”
HVAC AI Diagnoser
Leverage sensor data and AI to pinpoint root causes of performance problems, reducing diagnostic time and misdiagnosis.
“Diagnosing whether an electronic expansion valve (EEV) is gummed up by leak lock sealant, with no reliable diagnostic data or normal operating specs to compare against.”
“HVAC zone damper systems have unreliable air pressure sensors that require complex manual recalibration, and technicians lack diagnostic tools to verify sensor health.”
HVAC Detective
Combines odor detection with debris verification tools for HVAC technicians. Streamlines diagnostics of non-standard issues like chemical smells or compressor shrapnel contamination.
“Encountering an unusual dual filter-dryer configuration in a condensing unit that caused a restriction, requiring a custom field repair.”
“HVAC technician installed a new Midea/Moovair side discharge AC unit that is not cooling to the set temperature despite normal operating pressures, unlike the old unit.”
HVAC Diagnose Pro
A mobile app that pairs with Bluetooth manifold gauges to provide real-time diagnosis of refrigerant and system issues, overcoming connectivity problems and guiding technicians through complex troubleshooting.
“Difficulty diagnosing TXV problems in A2L refrigerant systems when charge is low”
“Unable to locate a very slow nitrogen leak in a small R134a system because conventional bubble testing fails to detect it.”
Individual Problems
PureRefrig Diagnostic
A commercial refrigeration site with reheat circuits is repeatedly losing compressors, suspected due to non-condensables, with no reliable field method to confirm their presence.
DiagAssist HVAC
Junior HVAC technician struggles with diagnostic uncertainty, lacks confidence in troubleshooting refrigeration circuits due to inconsistent measurements and inadequate field training.
SignalSnap HVAC Logger
Lack of a simple device to record on/off timestamps of a 24V signal over days for HVAC diagnostics.
VRF Diagnostics Pro
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.
VibeCheck Compressor Analyzer
A two-stage compressor intermittently fails or unloads when panel vibration occurs, causing inconsistent cooling and diagnostic confusion.
ErrorCode Navigator Pro
HVAC technician cannot diagnose or find support for Hitachi 53 error code (inverter board fault) on a specific unit.
NameplateDecode Pro
An HVAC professional is confused by the discrepancy between breaker and fuse ratings on a Mitsubishi nameplate, needing to understand why a 40A HACR breaker is listed alongside a 67A dual-element fuse recommendation.
CompressorCheck Pro
HVAC technician struggles to definitively diagnose inefficient scroll compressor due to ambiguous symptoms and lack of specialized diagnostic tools.
StaticPressure Pro
Unable to determine if HVAC system airflow problem is due to undersized return or duct static pressure, causing diagnostic confusion.
SmartCharge HVAC Analyzer
HVAC technician struggles with diagnosing a complex split system fault due to overcharging and a defective reversing valve, compounded by inaccurate refrigerant charge from prior contractors.
SubCool Pro
Service calls require multiple return visits because refrigerant charge is not set using proper subcooling targets, leading to persistent system performance issues.
HVAC DiagPro
Diagnosing oscillating subcool in a 3-year-old AC system with TXV and ECM air handler, where subcool predictably rises and falls without clear cause.
HVAC Diagnostic Pro
HVAC technician cannot diagnose why a new split system's second circuit has 0° superheat and 3° subcooling, with standard troubleshooting not affecting the readings, indicating a likely stuck TXV or other issue.
HVAC DiagPro
Diagnosing a persistent low supply air temperature / evaporator freezing alarm on a new RTU with suspected restriction but unable to locate TXV.
HVAC Diagnostic Companion
A heat pump system repeatedly freezes up every 3-5 days around midday despite normal charge and static pressure, and the technician cannot identify the root cause.
SpikeSnap HVAC Diagnostic Logger
Intermittent high head pressure spikes in an RTU with microchannel condenser, despite verified charge, new components, and clean coils—only occurs randomly and briefly, making diagnosis impossible with current tools.
ChillTrace Intermittent Analyzer
Intermittent, unpredictable high head pressure spikes in an HVAC RTU that trip the safety switch, making diagnosis extremely difficult.
GaugeFix Pro
SMAN manifold gauge displays blank SH or SC readings randomly on both plug-in and Bluetooth clamps, and no one at work can explain why.
HVAC Diagnostic AI
SystemVu software shows 'cooling prevented' with no clear alarms, and VFD communication faults persist despite bypassing VFD hardware, leaving technician unable to diagnose root cause.
FaultFlow Simulator
Senior HVAC technician struggles to diagnose a rare electrical phenomenon where a fan motor reverses direction when the compressor starts, with no board and a correct wiring configuration.
