Three techniques, one bubble
Electronic to narrow down, nitrogen to pressurise, foam to point at the exact spot — no blind dismantling.

Refrigerant leak in the air conditioner: detection and repair
Every yearly refill is €150 evaporating — literally. Locating the leak costs once and ends the cycle: electronic detector, pressurised nitrogen and a brazed repair that lasts summers, not months.
We reply in writing — no calls unless you ask for one.
Quick summary
We locate refrigerant leaks in Valencia from €90: electronic detector, nitrogen pressure test and tracer foam. Brazed repair, vacuum and recharge with a written guarantee. If you refill gas every season, this page is for you. WhatsApp: +34 617 307 409.
How is a gas leak found and what does it cost?
Leaks live in predictable places: flare connections loosened by vibration, elbows corroded by salty air, old brazes and pitted coils. The serious protocol combines an electronic detector, dry pressurised nitrogen and tracer foam until the exact bubble shows. Then the repair: torque-checked reseating, silver brazing or — with a pitted coil — the honest figure of coil replacement versus a new unit.

Why us
Leak hunters with a method
Dry nitrogen, never gas
Pressurising with refrigerant to hunt leaks is expensive and illegal — nitrogen is clean, dry and does not lie.
Silver brazing
The repair is brazed to factory standard and pressure-tested again before a gram is recharged.
Deep vacuum afterwards
After opening the circuit, the vacuum removes moisture and air — your compressor will be grateful for years.
The truth about pitted coils
A corroded coil may not be worth saving: we show repair and replacement side by side, in writing.

Sound familiar?
You almost certainly have a leak if…
- You refill gas every summer or two
- Performance sinks a little every month
- Oil stains show on pipes or connections
- The thin pipe frosts at full load
- The unit lost cooling after building work or a unit move
- Your last technician refilled "without finding anything"

Leak detection across Valencia and the metro area
Salty coastal air corrodes elbows and coils faster than anything — in Alboraya or Malvarrosa we see it weekly. We know where to look first.
FAQ
FAQ about gas leaks
How do I know if my AC has a gas leak?
The definitive sign: it needed a refill and later lost cooling again. Other clues — frost on the thin line, oil stains at connections, performance sinking month by month. The pressure test confirms it beyond doubt.
Is a refrigerant leak dangerous?
For people, at domestic charges the risk is low; for the planet and your wallet, less so: refrigerants are potent greenhouse gases and every refill costs €100–200. Legally and economically, the right answer is repair.
How much does finding and fixing a leak cost?
The search starts at €90. Reseating a connection is cheap; a braze, moderate; a pitted coil, the honest repair-versus-replace conversation. Always with written figures before you decide.
Why didn't my previous technician find the leak?
Micro-leaks are invisible without pressurising: with the unit off they barely escape. The nitrogen test at service pressure exposes them — it is the difference between searching and finding.
What if the leak is in the evaporator coil?
It can be brazed if the pitting is localised, or the coil replaced if corroded. On veteran units we set that figure against a new unit's — and you decide with both in front of you.
