Help Junior HVAC Techs Diagnose Faults Faster and Cut Callbacks
A callback costs you twice — the wasted trip and the dent in the customer's trust — and it almost always traces back to a fault read wrong the first time. R-Pro tackles this from both ends with two strong tools used together: a field app that puts AI diagnosis built on 600+ real cases in every tech's pocket, and an office ERP that shows you, in the books, which jobs actually came back.
On site — an experienced second opinion for every tech
- AI fault diagnosis built on 600+ real HVAC & refrigeration cases — the junior tech describes the symptom and gets likely causes and repair steps, not just a vague hunch.
- Scan the equipment nameplate and the data fills in automatically, so the diagnosis starts from the right model and refrigerant instead of a guess.
- Voice memos and photos capture what the unit was actually doing, so nothing gets lost between the site and the office.
- Per-customer service history travels with the tech — they can see what was done last time before they touch anything.
- Works fully offline, so it helps in a basement plant room or a rooftop with no signal, exactly where a junior tech is most alone.
In the office — see callbacks in the numbers, not just the complaints
- Per-customer ledger and service history let you spot the same site coming back for the same fault — the pattern a callback hides in.
- Accounting tracks sales, purchases, expenses and net profit, so you can see what a repeat trip really costs you in time and parts.
- Quotes, estimates, invoices and tax invoices keep every visit documented, so a return trip is never an unexplained gap.
- Inventory, suppliers and purchase orders mean the right part is on hand — a wrong part is its own kind of callback.
- Reports turn months of jobs into a clear view of which work, and which techs, generate repeat visits.
Field and office connected — the loop that actually reduces callbacks
- A job the junior tech finishes on site flows into the office books automatically — no double entry, no detail dropped on the way back.
- Every diagnosis, photo and voice memo is attached to the customer, so if a unit does come back the next tech starts fully informed.
- Customers, equipment and billing stay in sync across both tools, so the office sees the real story behind a return visit.
- One subscription gives you both the field app and the full office ERP, in 10 languages, so your whole crew works the same way.
Faster, surer diagnosis on site — clearer books in the office
R-Pro is two powerful tools in one subscription: a field app with AI fault diagnosis built on 600+ real cases that helps every tech read the fault right the first time, and a full office ERP — quotes, invoices, tax, accounting, inventory and a per-customer ledger — that shows you exactly where callbacks come from. Both in 10 languages, working together so on-site work flows straight into your books.

How does AI diagnosis actually help a less-experienced tech?
The tech enters the symptom and the app draws on 600+ real HVAC and refrigeration cases to suggest the most likely causes and the repair steps to check, in order. It is like having a senior tech on the line for every call — the junior tech still does the work, but they stop chasing the wrong fault.
Will this work where my techs actually are — no signal, old units?
Yes. The field app is fully offline, so diagnosis, nameplate scanning, photos and service history all work in a basement plant room or on a rooftop with no bars. Scanning the nameplate pulls the right model and refrigerant in even on older equipment.
How do I know it's really cutting callbacks?
The office ERP keeps a per-customer ledger and full service history, so repeat visits to the same site for the same fault show up clearly. With accounting and reports you can see what those return trips cost and which jobs generate them — not just hear about the complaints.
Is the office ERP a separate purchase?
No — and it is not an add-on either. The field app and the office ERP are two equal tools that come with one R-Pro subscription. Work captured on site flows into the office books automatically, so you run diagnosis and the back office from the same connected system.
