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
FaultSnap Remote Diagnostics
A lone field technician must troubleshoot and repair complex 3-phase chiller systems under intense observation without remote diagnostic tools or support, and intermittent faults don't show up during onsite visits.
MotorInsight Pro
A technician cannot reliably determine whether a motor has a ground fault or internal defect using only a standard multimeter, lacking a megger tester to confirm.
CombiPro Diagnostics
After replacing a burnt PCB board on a Navien combi boiler, the baseboard heating is not functioning properly and struggles to maintain heat, with no clear diagnosis available.
HVAC Detective Pro
A commercial HVAC technician is troubleshooting a noisy shutoff on a 1988 Trane air handler and needs to diagnose whether it's a worn bearing or bushing, but lacks experience with such old equipment and fears part scarcity.
A2L Wiring Assistant
Refrigeration technician struggles with confusing wiring and integration of new A2L-compliant evaporator controls, needing manual rewiring to get the system to work.
TXV Check Pro
A newly installed HVAC system has abnormally high superheat and subcool readings, and despite replacing the liquid line and drier, the suspected faulty TXV from the factory is causing performance issues.
CompuCool Diagnostics
An HVAC technician is unable to diagnose a persistent heat pump overcurrent/breaker trip issue despite following manufacturer service manuals, replacing breaker and inverter PCB based on tech support advice, and replacing the compressor, with all workarounds failing.
A2L Diagnostic Toolbox
HVAC technicians lack a standardized diagnostic tool for A2L sensor and mitigation board issues, leading to trial-and-error troubleshooting and delays.
DuctFlow Analyzer
Uncertainty about the science and practical outcomes of using oversized ducts with a smaller HVAC unit.
CoilAlert
HVAC technicians lack a clear indication when the coil door is open and struggle to diagnose low suction pressure during tune-ups.
LoadBoost Diagnostic
Hard to diagnose low charge or TXV issues during HVAC tune-ups on mild temperature days due to zero load.
ChillCalc Pro
Wireless HVAC pressure/temperature probes have unreliable connectivity and lack basic refrigerant calculations like superheat and subcool.
RefrigDiag Pro
Unable to diagnose whether a failing pilot assembly or main valve body is causing the Sporlan SORIT-15 EPR to not regulate or defrost properly on an old rack system.
EvacVue Gauge Sync
Different micron readings on liquid and suction sides during vacuum decay, causing uncertainty about proper system evacuation.
LeakSnap Pro
Leak detection on A/C systems is unreliable; standard methods (pressure test with nitrogen, soap bubbles, electronic sniffer) miss small leaks that only show under lower pressure when the system is running.
HVAC Detective Pro
Diagnosing intermittent TXV failure and hard-to-locate refrigerant leaks in rooftop and pancake units without proper access.
LoadCalc Pro
Homeowners are adding zones and square footage to existing HVAC systems without proper load calculation, leading to undersized equipment that will fail during peak seasons.
FridgeTech Mentor
New commercial refrigeration technician doesn't understand how walk-in refrigeration systems prevent liquid slugging without an accumulator, and needs guidance.
CompressorCheck Pro
When diagnosing a low refrigerant charge in an HVAC system, it's unclear whether the compressor has been damaged from pulling in air, and there is no established protocol to decide if leak repair is worth attempting before confirming compressor viability.
LeakSniffer Pro
Finding refrigerant leaks on multi-zone ductless HVAC systems is extremely difficult and time-consuming when visual, bubble, and sniff methods fail.
