Manufacturer warranties: a file nobody keeps — except the registry.

A manufacturer warranty only exists if someone knows it exists. A heat pump compressor is often covered for ten years, parts for five or ten, under two conditions almost nobody tracks: the warranty was registered on time, and the unit was serviced by a professional, with proof. On the day of the breakdown, the customer who has neither pays for the repair — and remembers who installed it.

The four dates that matter

• The installation: it sets everything else. It is on your invoice.
• The end of the registration window: with several manufacturers, the extended warranty depends on registering within 60 or 90 days of installation. A reminder thirty days after the installation is often enough to save years of coverage.
• Warranty ends by component: compressor, parts and labour do not have the same term. Keeping them per unit lets you warn the customer six months before the end — and offer the service that keeps the coverage valid.
• Every documented service: date, technician, work done. That is the proof the manufacturer will ask for.

What the registry does with those dates

In Byrsia, every unit carries its warranty end date and a “registered with the manufacturer” box; at import, the AI picks up the terms written on your invoices (parts, extended compressor or tank warranty). Units whose warranty is not registered get a registration reminder 30 days after installation; a warranty ending within six months is flagged on the record and surfaces under “To contact”; and for a claim, the maintenance-proof file exports in one click (Professional plan and up) — the unit's complete, dated history. The maintenance certificate handed to the customer carries a verifiable QR code.

Why it is a sales argument, not paperwork

“Your compressor warranty requires documented annual maintenance — we take care of it” is the sentence that gets a reply to a reminder, because it helps before it sells. It is true with most major manufacturers (always check each one's conditions: we write that on every page). And the day a customer claims, it is your file that defends their claim: the kind of service people tell the neighbour about.
