Car Air Conditioning Tullamarine
Aircon blowing warm? Regas alone often isn't the answer. We pressure-test, find the leak, repair properly, then regas — so it's still cold next summer.
Car Aircon That Stays Cold — Tullamarine
A regas alone is a quick fix that masks the real problem. If your aircon is blowing warm, the gas didn't evaporate — it leaked out. That leak might be a tired O-ring, a stone-damaged condenser, a corroded line, or a failing compressor seal. Top it up without finding the leak and you're back next year with the same problem.
At 6 Garden Dr we pressure-test the system, run a UV dye trace or sniffer test to find the leak, and quote the repair. Sometimes it's $50 of seals; sometimes it's a new condenser or compressor. Either way you'll know before we start. Once the leak is fixed we evacuate the system properly, hold vacuum, and recharge to manufacturer spec.
We service both R134a and the newer R1234yf systems (post-2017 cars), and we keep both refrigerants in stock. Common aircon work we see for Tullamarine, Airport West and Gladstone Park customers: failed condensers from stone damage, tired compressor clutches on older Holden and Ford utes, blocked cabin filters mistaken for low gas, blend door actuator failures, and electrical faults on cars where the compressor never clutches in.
What's Included in Every Car Service
Every air conditioning service at our Tullamarine workshop tests system pressure, identifies leaks, checks compressor and condenser health — not just a top-up and out the door.
Car AC Services We Handle
Melbourne summers punish a tired AC system. Every part of your auto air conditioning — diagnosed, regassed, or repaired at our Tullamarine workshop.
Regas & Recharge
Refrigerant recovered, system vacuum-tested for leaks, then recharged to manufacturer spec with the correct R134a or R1234yf gas and PAG oil. We don't just top up a leaking system — we find the fault first.
Leak Detection
UV dye injection and electronic sniffer testing to track refrigerant leaks at O-rings, hose crimps, condenser fins, and evaporator cores. We pinpoint the leak before any gas goes back in — no guesswork, no repeat regas.
Compressor Diagnosis
Noisy compressor, clutch not engaging, or pressures out of spec? We test compressor clutch coil, pressure switches, and internal valves. Rebuild or replace based on what's actually failed — not a blanket swap.
Condenser & Expansion Valve
Stone-damaged condensers and blocked expansion valves kill cooling performance fast. We pressure-test the high side, check sub-cooling, and replace condensers, TX valves, or receiver-driers where the system needs it.
Cabin Filter & Evaporator
Weak airflow usually starts at a choked cabin filter. We replace pollen filters, inspect the evaporator for ice-up or blockage, and check blower motor draw. Small job, big difference in how the cabin cools down.
AC Odour Treatment
That musty smell on start-up is mould and bacteria on the evaporator core. We treat the system with an antibacterial foam through the drain, clear the drain tube, and replace the cabin filter to stop it coming back.
