The field helper for HVAC/R technicians

For walk-in coolers and freezers, ice machines, furnaces, boilers, AC and heat pumps.

Scan a nameplate — model, serial, refrigerant, electrical data and common problems for that model.
Ask with photos — the app marks what to check on your photo, step by step, with normal values and safety reminders.
Voice report — talk through the job; get a clean service report the customer signs on your phone, as a PDF in English or French.
Works without signal — recordings and signed reports wait on the phone until you are back online.

Coming soon to the App Store for iPhone.

For trained technicians and apprentices. AI suggestions can be wrong — always confirm with your own readings and follow safety rules.
