When it comes to cooling your home in Melbourne, the type of air conditioning system you choose can significantly impact your comfort, energy bills, and lifestyle. Two of the most popular options are roof-mounted air conditioners and split system units—each with its own advantages.

At Melbourne Aircon Specialist, we help homeowners make the right choice based on space, budget, and long-term needs. Here's a closer look at both systems to help you decide what suits your home best.

🌤️ What Is a Roof-Mounted Air Conditioning System?

A roof-mounted system is typically installed on top of the home, distributing air through a series of ducts. It’s commonly used for centralised cooling—ideal for larger homes or commercial properties. These systems are hidden from view inside the home, making them a good choice if you want a cleaner, clutter-free interior.

Because the unit cools the entire house at once, it provides consistent airflow throughout. However, it usually requires more intensive installation, including ductwork and roof access, which can increase the overall cost.

❄️ What Is a Split System Air Conditioner?

Split systems are one of the most common choices for modern households. These systems consist of an indoor unit mounted on the wall and an outdoor compressor unit installed outside the home. They’re ideal for zoned cooling, meaning you can control the temperature in individual rooms based on use and preference.

They’re also easier to install, require no ductwork, and tend to be more energy-efficient for smaller or medium-sized homes. If you're looking to cool specific rooms—like bedrooms or a living area—a split system may be the more economical and flexible option.

🔍 Key Differences Between the Two

While both systems are designed to improve indoor comfort, they serve different needs:

Roof-mounted systems cool the entire home at once, making them ideal for large or open-plan layouts. They’re less visible indoors but often come with higher installation and running costs.
Split systems offer targeted cooling, allowing you to save energy by operating only the rooms in use. They’re faster to install, generally cost less, and are easy to maintain.

🏡 Which One Is Best for Your Home?

If you have a large property and want a seamless look with no visible units inside, a roof-mounted system may be the way to go—especially if you're building or renovating. On the other hand, if you're upgrading a single room or prefer more control over energy use, a split system offers flexibility, lower costs, and faster installation.
