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.
“HVAC technician struggles to measure CFM in flex duct using a hot wire anemometer because available resources only cover hard pipe duct, and flex is ubiquitous in his area.”
“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.”
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.”
“HVAC technician cannot diagnose or find support for Hitachi 53 error code (inverter board fault) on a specific unit.”
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.
“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.”
“Service calls require multiple return visits because refrigerant charge is not set using proper subcooling targets, leading to persistent system performance issues.”
HVAC AI Diagnoser
Leverage sensor data and AI to pinpoint root causes of performance problems, reducing diagnostic time and misdiagnosis.
“HVAC technicians struggle to take readings on micro channel coils due to sharp panels that require disassembly.”
“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 Detective
Combines odor detection with debris verification tools for HVAC technicians. Streamlines diagnostics of non-standard issues like chemical smells or compressor shrapnel contamination.
“Technicians need to manually compute or recall the specific measurements (return air wet bulb, return air dry bulb, supply air dry bulb) needed for HVAC diagnostics, which is an inefficient and error-prone process.”
“A homeowner detects a sweet syrupy smell in specific rooms but the HVAC technician cannot identify the source, and lacks a diagnostic tool for non-HVAC odor issues.”
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
FlexFlow CFM Toolkit
HVAC technician struggles to measure CFM in flex duct using a hot wire anemometer because available resources only cover hard pipe duct, and flex is ubiquitous in his area.
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.
FieldCheck Diagnostic Guide
HVAC technician forgets critical diagnostic steps in the field and has no reliable way to verify their diagnosis before leaving the job.
FCU Doctor
Aquastats on fan coil units in a university dorm are failing repeatedly, even after replacements, with no identified cause.
HVAC Diagnostic Assistant
Residential HVAC system (Trane) cannot maintain temperature with inadequate performance despite replacing evaporator coil, TXV, filter dryer, and refrigerant.
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.
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.
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.
InrushGuard Pro
HVAC technician needs a durable clamp meter that reliably measures inrush current for motor diagnostics, after his Fieldpiece SC440 became unreliable.
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.
GeoTech Diagnostic Pro
Geothermal heat pump trips on high pressure alarm within seconds of startup despite proper airflow and waterflow, preventing diagnosis or operation.
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.
GeoLoop Air Purge Pro
A geothermal heat pump repeatedly trips on high head pressure due to suspected air in the loop or insufficient water volume, causing return calls and diagnostic challenges.
CoolComp Helper
HVAC technician cannot diagnose why an old system with R407c refrigerant is running high head pressure despite standard troubleshooting steps, suspecting compressor-oil incompatibility.
HVAC FreezeWatch
A heat pump system randomly freezes every 4-5 days despite normal refrigerant charge and recent component replacements, and the technician cannot diagnose the root cause.
TechManual Access Pro
Cannot access service manual for Trane AC unit, which is locked behind a web portal, hindering diagnosis of intermittent failure.
CorroSense Pro
HVAC technician struggles to diagnose the root cause of recurring microchannel coil corrosion on Rheem units, lacking a tool to identify environmental or material factors leading to premature failure.
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.
