Car Air Conditioning Service & Re-Gas in Mascot

Re-gas, leak repair and anti-bacterial cleans for all makes.

If your vehicle's air conditioning isn't cooling like it used to, Hitech Auto Electrical & Mechanical can help. We recommend servicing your air conditioning every 12 months, because most systems slowly lose gas through hoses, O-rings and seals.

What can go wrong

Not using your air conditioning over winter causes internal seals to dry out and leak. Switching the system off also allows condensation to build up, creating an ideal breeding ground for bacteria and mould spores — which is where odours come from.

Anti-bacterial clean & pollen filters

A fresh pollen filter ensures optimal protection from dust, pollen and harmful exhaust emissions, good-quality filtered air, and windscreens that don't mist up in autumn and winter.

Frequently asked questions

How often should I re-gas my car air conditioning? +

Around every 12 months. Systems naturally lose over 10% of their gas each year through seals and hoses, so an annual service keeps the air cold and the components healthy.

Why does my air con smell musty? +

Moisture in the system creates a breeding ground for bacteria and mould. Our anti-bacterial clean and a new pollen filter eliminate the odour at its source.

Can you fix an air con that isn't cold? +

Yes. We diagnose the cause — whether it's low gas, a leak, a faulty compressor or a blockage — and repair it, then re-gas and test the system.
