AI Fault Diagnosis App for Refrigeration: Symptom to Cause to Fix
Most "AI" troubleshooting tools spit out generic textbook answers that fall apart the moment you're standing in front of a real unit. R-Pro is different: its AI fault diagnosis is built on 600+ real HVAC and refrigeration repair cases, so it walks you from symptom to likely cause to concrete repair steps. And R-Pro isn't only a field tool — it pairs a powerful diagnostic field app with a full office ERP, so the job you diagnose and fix on site flows straight into your books. Two strong tools, one workflow.
AI diagnosis built on 600+ real repair cases — not generic answers
- Enter the symptom in plain language (no superheat, low side pressure dropping, compressor short-cycling, ice on the evaporator) and R-Pro returns the most likely causes ranked by how often they actually appear in the field.
- Every result follows the same path technicians think in: symptom → cause → repair steps, drawn from a library of 600+ documented HVAC and refrigeration cases instead of a chatbot guessing.
- Scan the equipment nameplate with your phone and R-Pro auto-fills model, refrigerant and specs — so the diagnosis is tied to the exact unit in front of you, not a generic profile.
- Add voice memos and on-site photos while your hands are dirty, then mark which results actually helped so the guidance keeps getting sharper.
- Fully offline: the diagnosis, your case history and the nameplate scans all work in a basement plant room or rooftop with no signal.
A complete office ERP — quotes, invoices, accounting and inventory
- Build quotes and estimates, including itemized construction quotes, then turn the approved job into an invoice or tax invoice without re-keying anything.
- Set your OWN country's tax name and rate — VAT, GST or sales tax — so invoices and books are correct wherever you work, in any of 10 languages.
- Run real accounting: sales, purchases, expenses and net profit, so you can see what each job and each month actually earned.
- Track inventory, suppliers and purchase orders, and keep a running customer ledger of who owes what.
- Pull reports on revenue, costs and profit to manage the business side with the same precision you bring to a refrigerant charge.
Field and office, connected — diagnose once, no double entry
- The unit you diagnose and the parts you replace become part of that customer's service history, so the next visit starts with full context instead of a blank page.
- Issue a receipt on site the moment the job is done — and that same job feeds the office side automatically.
- Completed field jobs flow into the accounting books as sales, with no separate data entry back at the office.
- Customer, equipment and job records are shared across the field app and the ERP, so the office always sees what really happened on the truck.
- One subscription covers both tools — you're not stitching together a diagnosis app and an accounting package that don't talk to each other.

Get R-Pro →FAQ
Is R-Pro a field diagnosis app or an office program?
Both, and they're equals. R-Pro is a field app with AI fault diagnosis, nameplate scanning and offline service history, AND a full office ERP for quotes, invoices, accounting and inventory. They share one subscription and one set of data, so work you do on site flows straight into the books.
How is the AI diagnosis different from asking a regular chatbot?
It's grounded in 600+ real, documented HVAC and refrigeration repair cases rather than open-ended text generation. Results are ranked by how often a cause actually shows up in the field and laid out as symptom → cause → repair steps, so you get an answer you can act on, not a paragraph of theory.
Does the diagnosis work with no internet on site?
Yes. The diagnosis, your case and customer history, and the nameplate scans all work fully offline, which matters in basements, plant rooms and rooftops where there's no signal. Data syncs to the office side when you're back in range.
Can I set my own country's tax for invoices?
Yes. You set your own tax name and rate — VAT, GST or sales tax — so tax invoices and your accounting are correct for your country. R-Pro runs in 10 languages for the same reason.
