Why extraction canopies fail

TSPM FIELD NOTES
Grease does not evaporate

An extraction canopy does not fail suddenly. It fills, slowly, with a film that thickens every service until airflow drops far enough that the kitchen notices the heat before anyone notices the fan.

By then the ductwork above it is carrying the same film, and the cost has moved from a filter change to a deep clean and, occasionally, to a claim your insurer would rather not receive.

How a request works

Three steps, no call centre, and one email that decides everything.

1
You Send It
& A Person Reads It

Your request arrives at our office in Winterthur, where somebody actually reads it — not a queue, not an auto-responder rehearsing how much your enquiry matters to us. Tell us what has stopped working, where it is, and how badly you need it back. Photographs help far more than adjectives.

2
We Answer
& Usually Ask Something

You get one of two replies, quickly: a price with a time we can be there, or a question. The question is almost always about access, make or model — the unglamorous detail that decides whether our technician arrives with the right part or with an apology.

3
You Get The Email
& Only Then Is It Booked

Nothing is reserved until a written booking confirmation reaches you by email. Not when you send the form. Not when we reply. When that email lands. Until it does, the slot is genuinely still free — which is our polite way of saying somebody else can take it.
