Sydney air conditioning systems can noticeably stop performing well, with systems estimated to lose close to 30% of their efficiency within the first few years of operation..

The Fix?

An ac booster is the perfect solution – it’s an excellent method to improve the efficiency and performance of older systems, as well as protecting a new air conditioning unit.

The booster process consists of installing an oil-based product which creates a protective layer inside the system. This removes oil fouling by replacing stagnant oil and ensuring a refrigerant can travel through the system smoothly. The process must only be performed by a qualified Proven technician, and results take effect immediately on residential systems.

For How Long?

A once off solution that lasts the entire life of the gas charge inside your system.

  • Excellent customer service. Turned up when they said they would, were very pleasant, cleaned up the mess, and made sure we were happy. I’m addition to their competitive price they also had excellent music taste.

    I couldn’t recommend Proven AC enough! The service provided by Zac and his team was exceptional. After having some issues, I got Zac in to look at my 10 year old air conditioning system, which had never been serviced before and naturally he found a handful of issues. Zac thoroughly and simply explained each of the issues and then gave me candid advice on whether the fix was absolutely necessary or not. Genuine service and very good value
