What we do

Diagnosed properly, then repaired

Most air conditioning complaints are not simply "low on gas". We test before we quote, so you don’t pay for refrigerant you never needed.

Air Conditioning Servicing & Re-Gas

Recover, evacuate, vacuum-test and recharge to your vehicle’s exact refrigerant weight — R134a or R1234yf.

Leak Detection & Repairs

Nitrogen pressure testing, electronic detection and UV dye — we find the leak before you pay for gas twice.

Full System Diagnosis

Pressures, temperatures, electrics and control modules — the cause found before anything is replaced.

Evacuation & Vacuum Testing

The stage most cheap re-gasses skip: moisture boiled out and the system proved sealed before any gas goes in.

Compressor & Component Replacement

Compressors, condensers, evaporators, driers and expansion valves — fitted with a flush and the right oil charge.

Hose Repairs & Custom Lines

Hose assemblies made up and crimped on site — far cheaper than replacing a whole factory line.

Retrofits & Classic Vehicles

Older systems converted from banned R12 to R134a — done properly, with the right oil, seals and hose.

Truck, 4×4 & Machinery Air Conditioning

Prime movers, rigids, buses, 4x4s, excavators and tractors — serviced in the yard, on site, where they sit.

Cabin Filter & Odour Treatment

That damp, musty smell when the fan starts is mould on the evaporator. We clear it at the source.

How it works

Four steps, usually one visit

Call or book online

Tell us the vehicle, what it is doing, and where it is. Most enquiries are answered the same working day and we can usually give you a ballpark on the phone.

We come to you

Home, workplace, depot, yard or farm, anywhere across the western suburbs of Melbourne. The van carries refrigerant, nitrogen, oil, hose and crimping gear, so most jobs finish in one visit.

Tested, then quoted

Pressures, vent temperature and a nitrogen leak test where needed. You get a firm price for parts and labour before any work starts, and an honest answer if it isn’t worth repairing.

Repaired and proven

We re-test after the repair and show you the vent temperature on a thermometer before you pay. All work is guaranteed.

The part most re-gasses skip

Why vacuum matters more than gas

Moisture is what kills compressors. Water trapped inside a system combines with the refrigerant oil to form acid, and that acid eats the compressor from the inside out. Pulling a deep vacuum drops the boiling point of water far below ambient temperature so any moisture turns to vapour and gets drawn out.

Holding that vacuum is also the honest leak test. If it creeps back toward atmospheric pressure, the system has a leak and no amount of refrigerant will fix it — so we stop and tell you, rather than charging a system we already know will empty.

Recovery machine, gauges, nitrogen, both refrigerants, oil, dye and hose crimping gear — all on board.

Workshop on wheels

Everything needed to finish the job, in the van

A mobile service is only worth having if it can actually complete the work. The van carries the recovery and recharge machine, a vacuum pump, manifold gauges, dry nitrogen for leak testing, both R134a and R1234yf, PAG oils, UV dye, seals and O-rings, plus hose stock and crimping equipment.

That last one matters more than it sounds: when a hose has failed and the factory part is a whole line assembly — or isn’t made any more, as on older vehicles and machinery — we can make up what fits on the spot rather than booking you in again.
