HVACDiagnostics & Troubleshooting4HighField Technician$ implied

Finding refrigerant leaks on multi-zone ductless HVAC systems is extremely difficult and time-consuming when visual, bubble, and sniff methods fail.

Existing leak detection methods rely on accessible fittings and line sets, but on multi-zone ductless systems, leaks can occur in hidden evaporator coils or buried lines that are impossible to reach with standard tools, forcing time-consuming isolation and long hold tests.

Workarounds Described

  • visual inspection for oil
  • nitrogen bubble check on fittings
  • add refrigerant and sniff with electronic detector
  • isolate each zone individually and pressurize, then come back a week later to check pressure drop

Implied Software Gaps

  • Portable device with combined ultrasonic and tracer gas detection that works on enclosed or inaccessible line sets
App Concept

LeakSniffer Pro

A portable, sensitive acoustic and tracer gas leak detector specifically designed for ductless mini-split systems. It combines a high-sensitivity ultrasonic microphone that detects the sound of escaping refrigerant through walls and insulation, plus a wireless tracer gas sniffer that can pinpoint the smallest leaks without needing to access every fitting. It cuts diagnosis time from days to minutes.

Key Features
  • Ultrasonic acoustic leak detection (detects hiss through drywall or insulation)
  • Wireless tracer gas sniffer with pinpoint accuracy
  • Multi-zone system mapping to quickly isolate affected circuit
  • App-based reporting and leak location tagging
Target Users: HVAC technicians servicing multi-zone ductless mini-split systems, especially in residential and light commercial settings (solo operators to mid-size service companies).
Revenue Model: $350–$500 one-time hardware purchase + $19/mo app subscription for advanced diagnostics and cloud-based leak history
