My air conditioner required a deep clean after being neglected for a few years. I contacted them through their website, and after a bit of back-and-forth over text, booked their premium service. The technician arrived right on time, was very professional, thorough, and cleaned up completely after finishing the job. Overall, exceptional service.Posted on Google![]()

Proven Aircon replaced my old faulty aircon system with a new Mitsubishi AC system. This included replacing internal components in the roof space and upgrading switches in the electrical board. The Proven Aircon team were friendly and professional and very responsive for both call out and installation services. It was all hands on deck and my system was installed in under a day! Admittedly I was initially shocked by the cost to replace a ducted aircon system, but Proven Aircon prices were very reasonable in comparison to other quotes received. I would highly recommend Proven Aircon for their great service.+0Posted on Google![]()

The team from Proven Air were exceptional from the initial consultation to the installation and the clean up. When they say they will turn up within a 2 hour window, they did so at the start of the window. Huon, the installer and Tony the electrician were extremely courteous, always took their shoes off when inside and efficiently installed the unit in about 2 hours. When he left, he took all of the packaging and boxes with him. I am going to use this organisation to service and install all of my air conditioning needs as long as they are in business. This is how you run a business. They are a 6 star service.Posted on Google![]()

What is Subfloor Ventilation?
Subfloor ventilation is a crucial component of a healthy home. It involves the exchange of air beneath your home, targeting the often-neglected space between the ground and the underside of your floor. This space, if improperly ventilated, can lead to a range of issues, including moisture buildup, which can result in mould growth and damage to the structural integrity of your property.
Our Subfloor Ventilation Guide breaks down how the process works and what to look for beneath your own floor.
How Does it Work?
Our subfloor ventilation systems work by ensuring a consistent flow of fresh air into the subfloor space, while expelling damp, stale air. This process is achieved through strategically placed ventilation fans, which help maintain optimal humidity levels.
Benefits of Subfloor ventilation:
Mould Prevention
Subfloor ventilation is a proactive measure against mould growth, protecting your home and your family's health.

Explanatory information directly from The
National Construction Code Australia.
Take a look at the graph from the National Construction Code to understand the impact of effective subfloor ventilation on humidity levels:
“Subfloor ventilation is cross ventilation of the subfloor space between the underside of the subfloor and the ground surface under a building.
Ground moisture rising into or entering the subfloor space can create a damp environment which encourages timber rot, fungus growth and the potential for termite activity. Subfloor ventilation increases air flow, reducing any damaging water vapour in the subfloor space.”
How Does it Work?
By understanding how ventilation works effectively in the diagram above, we can begin to grasp the significance of air-flow and humidity, especially in Australia, and the essential requirements for subfloor ventilation.
Whether you require subfloor ventilation fans or a comprehensive ventilation kit, we have the expertise to provide you with a tailored solution. Our team of experts at Proven Air Conditioning will conduct a thorough assessment of your subfloor space to determine the optimal solution for your needs.

The first step is to have a professional assessment of your subfloor space. This may include an inspection of the area, measurement of the space, and evaluation of any existing ventilation systems. The cost of the assessment will depend on the complexity of the space and the expertise required.
Once the assessment is complete, the next cost involves the subfloor ventilation system itself. This may include the cost of ventilation fans, ducting, and other components. The cost will depend on the size of your subfloor space, the type of system required, and the quality of the components.
The installation of the subfloor ventilation system will require the expertise of technicians. The cost of installation will depend on factors such as the complexity of the system, the accessibility of the subfloor space, and the time required for installation.
Depending on your specific needs, there may be additional services that can incur additional costs. For example, if there are structural modifications required for the installation, such as creating ventilation openings or sealing gaps, these services may involve additional expenses.
