Wireless HVAC pressure/temperature probes have unreliable connectivity and lack basic refrigerant calculations like superheat and subcool.

Existing wireless probes fail in reliable Bluetooth connectivity and do not automatically calculate superheat/subcool, forcing techs to use a separate manifold gauge or manual calculation.

Workarounds Described

uses separate digital manifold gauge because probes don't work
manually calculates superheat/subcool without app support

Implied Software Gaps

Reliable wireless probe connectivity for HVAC diagnostics
Automatic superheat/subcool calculation integrated into probe app

App Concept

ChillCalc Pro

A wireless HVAC diagnostic tool that pairs rock-solid Bluetooth probes with an app that automatically calculates superheat, subcool, and other key metrics. Unlike NAVAC, it prioritizes reliable connectivity and one-tap readings.

Key Features

Stable Bluetooth 5.0 connection up to 50ft
Automatic superheat and subcool calculation
Real-time pressure and temperature graphing
Work order export and photo tagging

Target Users: HVAC service technicians and contractors in residential and commercial field service, typically at companies with 1-20 techs

Revenue Model: $199 per probe set (hardware) + $9.99/mo app subscription for cloud storage and advanced reporting
