Air-Conditioning Regas, Repairs & Heating

Stay cool in summer and clear-sighted in winter

Your car’s HVAC system cools the cabin, heats it, filters the air and keeps your windscreen clear on damp Melbourne mornings. We regas, test and repair the whole system – compressors, condensers, evaporators, blower motors and climate control panels – for both older R134a cars and the newer R1234yf systems found in many European models. The result is a cabin that cools fast, heats properly and smells fresh.

How We Work

Tested, Traced and Properly Recharged

We never just add gas and hope. Every job starts with finding out what’s actually wrong.

Pressure Testing & Leak Detection

We check pressures and vent temperatures, then use UV dye and an electronic detector to track down leaks – even the slow ones that take weeks to show.

Once the fault is fixed, we vacuum out moisture and recharge the system to the exact weight your manufacturer specifies.

Symptom & Usage Consultation

We ask what you’ve noticed: warm air, odd smells, rattles from the dash or windows fogging up. We also check fans, belts and the climate control module for stored faults before recommending anything.

GUARANTEES

From Warm Air to Cold Vents

Licensed Refrigerant Handling

Refrigerant work is carried out by appropriately licensed technicians, as Australian regulations require.

Fix the Leak, Not Just the Gas

If gas is escaping, we find where and repair it before recharging.

Vent Temperature Checked

We measure outlet temperature before you collect the car, so you know it's working as it should.

HVAC Repair & Service - FAQs

Common questions about car air-con and heating
Why is my car air-con blowing hot air?

Usually a refrigerant leak, but it can also be a failing compressor, a blocked condenser or an electrical fault. A pressure and leak test tells us which.

A sealed system shouldn’t need regular regassing. If it loses cooling every summer, there’s likely a leak worth finding, and a check every one to two years is sensible.

They’re two types of refrigerant. R1234yf is newer, kinder to the environment and common in cars built from the mid-2010s, particularly European models, and each needs its own equipment.

Mould and bacteria can grow on the evaporator and in a clogged cabin filter. A new filter and an antibacterial treatment usually clears it up.

Yes. Heater faults often trace back to low coolant, a blocked heater core or a sticking blend door, so we check it alongside the cooling system.

Your air-con dries the air blowing onto the windscreen. If it isn’t working, moisture builds up on the glass, which can be a safety issue in wet weather.

A regas and performance check usually takes around one to two hours. Leak repairs or part replacements can take longer, depending on parts.

Spring is ideal. Getting it checked before the first 35-degree day means no waiting when everyone else books in, and it pairs well with a precautionary maintenance visit.
