Pressure test
✓Nitrogen, held
This page is exactly what happens when Korvent works on your equipment — so you know what you're buying before you buy it.
You get a confirmed date and a reminder before we arrive. No “sometime Thursday.”
Manufacturer's procedure, manufacturer's torque figures, no shortcuts. Pipework is pressure-tested with nitrogen and vacuum-tested before any refrigerant flows.
Every brazed joint is made with nitrogen flowing through the pipe. That one step is why our systems won't die mysteriously three years in. Most firms skip it. We never do.
Pressures, temperatures, superheat and subcooling — the numbers that prove a system is healthy, not our opinion that it is.
The same day, you have an email: photos of what we found, photos of what we did, the readings, parts used, and what it means in plain English. No jargon, no mystery invoice.
If your equipment holds refrigerant, the law makes you — the business owner — responsible for keeping records: leak checks on schedule, certified engineers, where the gas went. Fail an inspection and it's your fine, not your engineer's.
Every Korvent visit files itself. Kept digitally, dated, ready to forward the day an inspector or your insurer asks. You do nothing. That's the point.
Refrigerant doesn't get used up — if it's low, it leaked. Topping up without fixing the leak means you pay for the same gas twice and the leak's still there. We find it, fix it, prove it, then recharge.
Repeatable work is priced on this website. Anything bespoke gets a written quote — and the quote is the price.
If you can't explain your own service report to someone else, we've written it badly. Tell us.
Contract prices and callout rates go on this website before we take our first booking — in numbers, before you ever ring us. Nobody else local does that.
Korvent UK begins trading in early 2027. Before we take our first job, every Korvent engineer will hold City & Guilds 2079 Category 1 — the full F-Gas qualification — and the company will hold REFCOM certification. Certificate numbers on every report, from the first report.
