HVAC technician struggles to locate refrigerant leaks in large commercial systems with hidden line set runs, wasting time and nitrogen.

Current method of pressurizing with nitrogen and listening for leaks is ineffective when the leak is small, the lineset is long, or there are obstacles (like multiple floors) that prevent hearing the leak, leading to wasted time and gas.

Workarounds Described

Uses nitrogen pressurization and tries to hear the leak in a large, noisy factory
Has another technician add bursts of nitrogen while listening on different floor

Implied Software Gaps

A refrigerant leak detection tool that can pinpoint leaks in large, multi-floor commercial systems without relying on hearing or nitrogen pressure alone

App Concept

LeakSniffer Pro

A handheld electronic refrigerant leak detector with enhanced sensitivity and a long-range directional probe. It uses heated diode or infrared sensor technology to pinpoint leaks even in noisy, hard-to-reach areas. Integrates with a mobile app to log leak locations and generate repair documentation.

Key Features

High-sensitivity sensor for small leaks
Directional probe for long-range detection
Audible and visual leak indication
Mobile app for leak logging and reporting

Target Users: HVAC service technicians in commercial and industrial settings, particularly those servicing large systems with extensive line sets.

Revenue Model: $499/unit hardware with optional $19.99/mo app subscription for data logging and analytics, or $299/unit with $29/mo subscription (hardware subsidized).
