HVAC technicians cannot properly diagnose and repair high head pressure issues on Magic Pak units because the design prevents running the unit when the coolant tray is pulled, blocking access to critical components like the TXV and condenser fan.

These basic checks don't address the core issue of inaccessible components; no tool allows testing TXV or condenser fan while the unit is assembled and running.

Workarounds Described

Recover refrigerant, cut open line to add T with schrader for high side readings
Slide out 200 lb coolant tray (can't run unit) to access TXV/condenser fan
Gamble on repairs: change TXV and filter drier or condenser fan without testing

Implied Software Gaps

Wireless diagnostic sensor system that works without moving the coolant tray

App Concept

PakDiagnose Pro

A diagnostic tool with wireless sensors that can be attached to the TXV and condenser fan without needing to slide out the coolant tray. It provides real-time temperature, current, and pressure readings while the unit runs, allowing technicians to pinpoint restrictions or fan failures without guesswork.

Key Features

Wireless clamp-on temperature sensors for TXV inlet/outlet
Non-contact current probe for condenser fan motor
Real-time data streaming to technician's smartphone
Guided diagnostic workflow for Magic Pak high head pressure

Target Users: HVAC field technicians maintaining Magic Pak units in multi-family buildings (condos, apartments)

Revenue Model: $199 one-time hardware kit + $29/mo SaaS subscription for data logging and reporting
