An HVAC Troubleshooting App Built on 600+ Real Repair Cases
Most diagnostic apps hand you textbook theory and leave you to guess in the field. R-Pro is different: its AI fault diagnosis is built on 600+ real HVAC and refrigeration repair cases, so symptom-to-cause-to-fix matches what actually happens on a unit. And it doesn't stop at the field — R-Pro pairs a powerful on-site app with a full office ERP, two strong tools that share one workflow so the job you finish on a rooftop lands in your books automatically.
Diagnosis Grounded in 600+ Real Cases, Not Generic Theory
- Enter the symptom and R-Pro walks you from symptom to likely cause to concrete repair steps, drawn from a library of 600+ real HVAC and refrigeration cases rather than generic checklists.
- Scan an equipment nameplate or a parts receipt and R-Pro auto-fills the model, refrigerant, and details — no squinting at a faded label or retyping a serial number.
- Capture voice memos hands-free while you work, so you describe the fault as you see it instead of stopping to type with gloves on.
- Every visit is logged as per-customer service history, so the next time you're back on that unit you already know what was done and what failed before.
- Fully offline — diagnosis, scanning, history, and on-site receipts all work in a basement plant room or a remote site with no signal.
A Full Office ERP That Runs the Business Side
- Build quotes and estimates, including itemized construction quotes, then turn them into invoices and tax invoices without re-keying anything.
- Set your OWN country's tax — name it VAT, GST, or sales tax and apply your own rate, so the paperwork is correct wherever you operate.
- Run real accounting: track sales, purchases, expenses, and net profit instead of stitching numbers together in a spreadsheet at month-end.
- Manage inventory, suppliers, and purchase orders so you know what's on the truck and what needs reordering before a job stalls.
- Keep a customer ledger and pull reports that show how the business is actually performing — not just whether a single job got paid.
Field and Office, Together — One Workflow, No Double Entry
- A diagnosis and repair finished on site flows straight into the office books — the job, the cost, and the customer link carry over automatically.
- Issue a receipt to the customer on site, and the same transaction is already recognized in your accounting with no second data entry.
- Both tools run in 10 languages under one subscription, so your field crew and your office work in the same record set.
- These are two equal products — a powerful field app and a powerful office ERP — designed to work as one workflow, not one bolted onto the other.
- Because the real-case diagnosis data and the financial records live in the same system, what you fix and what you bill never drift apart.

Is R-Pro a field app or an office program?
Both — and they carry equal weight. R-Pro is a powerful on-site app for AI diagnosis, nameplate and receipt scanning, voice memos, service history, and field receipts, plus a full office ERP for quotes, invoices, accounting, inventory, and suppliers. They share one workflow, so you get field and office in a single subscription.
What makes the diagnosis different from other HVAC apps?
It's built on 600+ real HVAC and refrigeration repair cases. Instead of generic theory, R-Pro maps your symptom to the causes and repair steps that have actually shown up in the field, which is what a working tech needs when a unit is down and the clock is running.
Can I set the tax to match my own country?
Yes. You set your own tax name and rate — VAT, GST, or sales tax — so your invoices and tax invoices are correct for wherever you do business, across all 10 supported languages.
Does it work with no internet on site?
Yes. The field app is fully offline — diagnosis, scanning, voice memos, customer history, and issuing receipts all work without signal. When you're back online, the work syncs into the office ERP automatically with no double entry.
