No standard reference tool exists for checking resistance (ohms) values on different HVAC electronic components.

Technicians lack a quick, reliable chart or formula for expected ohms on HVAC components (transformers, contactors, etc.), forcing them to rely on memory or guesswork.

Mobile app with searchable ohms reference database for HVAC components

App Concept

OhmCheck HVAC Reference

A mobile app providing instant lookup of typical resistance values for common HVAC components. Users select a component type and model, and the app displays expected ohms range and diagnostic tips. Integrates with multimeters via Bluetooth for real-time comparison.

Key Features

Searchable database of ohms values for transformers, contactors, capacitors, fan motors, and more
Bluetooth connectivity to multimeters for live readings comparison
Component identification by photo (use phone camera to identify model)
Works offline for field use

Target Users: HVAC technicians and field service professionals at companies of any size

Revenue Model: Freemium with $9.99/mo pro subscription for unlimited access and Bluetooth integration
