an ARC-licensed mobile regas charged by weight, with a UV-dye leak check. NAZTECH comes to you across the City of Casey. Free quote.
Berwick sits up on its hill at the commuter end of the City of Casey, where a long freeway run in a warm car is nobody’s idea of a good start to the day. Whether the cold has faded in the family sedan that does the daily drive or the touring 4WD kept for weekends away, NAZTECH brings the aircon work to your driveway instead of asking you to give up half a day at a workshop. We recover the spent refrigerant, work out why the cold left, and charge the system back to the exact gram the maker calls for, all on site. The licence that makes that legal is ARC No. AU066885, the authority to recover and replace gas rather than guess a top-up. So when a Berwick car needs a regas, the leak check comes first, because pumping refrigerant into a system that weeps only sends it straight back out. Call 0449 992 695 or send an online enquiry, and we will find a same-day or next-day slot to suit.
When the vents turn warm on the morning commute, a flat refrigerant charge is the obvious suspect, but it is only one of several. A slow leak quietly bleeding the gas down, a compressor that no longer pumps, airflow choked at the condenser, or a blower motor on the way out all read the same way from the driver’s seat. Tip fresh gas into any of those and the cold lasts days, not the season.
So the bottle stays shut until the system has been read. A performance test runs the aircon hard, takes the high and low-side pressures, watches the compressor clutch cut in and out, and checks what is actually reaching the vents. A genuinely low charge on a system that is otherwise sealed is the easy case, and a refill brings the cold straight back. When the pressures say gas is escaping, UV dye leak detection traces it before a single gram goes in, because refilling a system that leaks just books you in again next month.

When the test says the system genuinely is just low, how the gas goes back in decides whether the cold lasts one summer or many. Every car leaves the factory with a refrigerant charge measured in grams, listed on a label under the bonnet, and the job is to match that figure exactly.
That is why a real regas runs as a measured sequence, not a quick squirt: the old gas is recovered and captured, the system is held under vacuum to prove it is sealed and to draw off any moisture, then the precise weight of fresh refrigerant goes in with fresh oil. The full recover, vacuum and weigh-in sequence is set out on our mobile car aircon regas page.
Skip the scales and the rest is guesswork. Overcharge the system and it cools worse while the compressor works too hard; undercharge it and the air is weak from the first hot morning. Weighing the gas in is simply how you stop guessing in either direction.
Book NAZTECH and the person who arrives is the owner, Sharfraz Nazim, a trade-qualified Auto Electrician and air-conditioning technician with around ten years on the tools across family cars and heavy fleets. Refrigerant work is regulated: handling, recovering and buying it without an ARC licence is against the law, and Licence No. AU066885 keeps the gas on your car recovered and replaced to standard.
The rest is there to check before you book. NAZTECH carries $10 million in public and product liability cover. Parts and labour are backed for 12 months or 20,000 km, and any battery replacement carries a 24-month warranty. The business opened in 2023, and the work behind it already runs past 400 vehicles repaired and 200 installations, with the diagnosis landing on the real fault about nine times in ten. Under all of that sit 44 five-star Google reviews, most still by word of mouth.

The usual booking costs you the car for half a day: drop it off, organise a lift, double back later. Going mobile turns that around. The gear comes to the house, the work car park or the kerb, the car stays where it is, and you deal face to face with the technician doing the job.
Gas is only one of the things the van pulls up with. When the test points past the charge to a part that has actually failed, the same visit can swap a tired compressor or make up a fresh hose on the spot where a pressure line has split, so a dead system rarely means booking a second day off. The same kit looks after the hatchback on the school run, the sedan that lives on the freeway, and the tow-ready 4WD that only earns its keep on the trip away, with most jobs done same-day or next-day.
There is no honest flat price, and the cheap figures you see advertised only hold if a system is sound and merely short on gas. Two things move the real number: the refrigerant your car runs, since the older R134a and the newer R1234yf sit well apart on the cost of the car aircon gas alone, and whether the system is holding a charge at all, which no one can know before testing it.
So with NAZTECH the price follows the diagnosis. You get a free quote by phone or online, the call-out fee confirmed before the van leaves, and a written quote for any parts before that work goes ahead. First-time jobs are settled on completion, by card or tap-and-pay on site. Because the leak check is part of the regas, you are never billed to put gas into a system that leaks it back out. That is the honest approach to a car Air Conditioning repair: a price that reflects what the car actually needs, never a flat rate pinned on before the system has been tested.
A mobile regas runs just as easily to the rest of the City of Casey and the Cardinia corridor next door, so the suburbs around Berwick get the same come-to-you service:
Up on the Berwick hill, where the daily freeway run and the weekend tow both lean on the aircon, a charge set by the scales is the one still blowing cold when the next summer comes around.
If a low charge is the whole problem, a regas is the cheapest fix that actually lasts. If a part has failed or the system is leaking, gas on its own will not hold, so we test the system first and tell you which of the two you are dealing with before the bottle is opened.
