What cooling option is best for you?

Wall split systems for cooling

Wall split systems are a very popular option these days, and are best suited to cooling a specific room quickly. With advances in technology, these units are becoming more and more energy efficient, which will help to decrease your power bills and emissions. Wall split systems can also double as a heating unit in the cooler Melbourne months.

Ducted split systems for cooling

A step up from the wall mounted split system, the ducted split system will deliver cool air to rooms throughout your home strategically placed ducts. These units are hidden away inside the roof cavity, which means they are subtly kept out of site and very quiet – you won’t even know it’s there!

Evaporative cooling

Evap cooling is one of the most cost efficient ways to cool your home – depending on the size you could cool your home for as little as 17 cents per day! Whisper quiet, and won’t dry out your skin, evaporative cooling is also better for the environment as it produces lower greenhouse emissions.

Add-on cooling

Add-on cooling eliminates the need for you to have two separate units for both heating and cooling. Add-on cooling units are added to your existing gas-ducted system to transform it into both a heating and air-conditioning unit. High efficiency also means this option will keep operating costs low.


We all know how quickly Melbourne can cool down, especially in the winter months – so it’s always comforting to know you’ve got a quality heating system in your home that can withstand those chilly days. If you need to upgrade your home’s heating system, or even just need a service of your existing unit – give us a call to see how we can help.

What heating system is right for you?

Wall split systems

Best for heating single rooms, such as a lounge room, study or bedroom. Wall split systems can also double up as an air conditioner in summer, which makes them a very versatile and popular option.

Ducted split systems

These systems can also be used for both heating and cooling in your home, and are highly efficient and effective, delivering warm air into rooms through concealed ducts around the home.

Still not sure what system is right for your needs? No problems, give one of our friendly team a call, and we can have one of our experienced technicians come to your home to help you decide on the best heating solution for your needs.
