30+ years
of air conditioning industry experience


Air conditioner gas leaks can reduce cooling performance, increase running costs and cause long term damage if left untreated. With 30+ years’ experience, our technicians accurately identify the source of the leak, carry out proper leak rectification, and regas your system only once the issue is fixed.
We service all air and gas systems and ensure your air conditioning is safe, efficient and operating as it should.

An air conditioner gas leak is not always obvious at first, but there are several warning signs to look out for:
If you notice any of these signs, turn your air conditioner off and contact us straight away. Even minor gas leaks can reduce system efficiency, while more serious leaks may pose health risks if left untreated.
Our experienced technicians guide you through every step, from the initial assessment through to leak rectification, regassing and ongoing system care.
If additional parts are required, we provide a clear report and transparent quote before any work is carried out, so you can make an informed decision with confidence.

I would highly recommend Robert Air Conditioning company I needed a split system put in my elderly mothers home. I contacted Roberts and was amazed how efficient Monique and Mitchell were. On the day of installing Mitchell and his apprentice were very professional and polite after Mitchell was finished he explained to my elderly mother how to use the remote to her new air con now thats service thank you so much
Staff were friendly and helpful from the start. Good communication before install, serviceman was friendly and thorough, the job was a little more complicated than expected but he took it in his stride and still got it done the best he could - even took a call from my husband half way through the job to go over everything with him and answer questions. Mel followed up to make sure we were happy after install as well. Great communication, no complaints at all from me. Highly recommend! Thanks, Roberts air conditioning!
The process from quote to completion was excellent and painless. Everyone was professional and committed to doing the job well, not just getting it done.
The Roberts team were great and jumped in to help us with a very long drawn out repair when we were unable to get a response from the original installer. Monique was so helpful and responsive! On the day Jake the technician was on time (so rare these days!) and very polite. I would highly recommend the Roberts team. Thank you
