How to Determine the Right Split System Size for Your Home

Determining the right size split system for your home is not always a straightforward process. Ducted split systems in Melbourne come in many different sizes and will vary based on their manufacturer and model. Getting the sizing right for your air conditioner is important, as buying an air conditioner that is either too big or too small for your space will lead to an unnecessary increase in the cost of your energy bills. This article will go over why split systems are a great choice, the best ways to determine the right split system for your home, and other factors you should be aware of when it comes to sizing the air conditioner for your home correctly.

Why Are Split Systems a Great Choice?

Ducted split systems in Melbourne are becoming the preferred way to cool the home, especially when it comes to replacing conventional air conditioning units in older homes. While split systems generally perform better in smaller spaces, they can be designed and configured to adequately cool larger spaces and houses as well. Split systems are noted for their particular ease of installation, with most split systems taking less than a day to install. As a result, they’re generally cheaper to install than other types of air conditioning and cooling. Split systems are also discrete in their appearance, with the bulky and loud compressor unit installed outdoors.

How to Determine the Right Size

Determining the right size ducted split system can be tricky, as there are multiple variables to account for. For instance, you’ll need to have adequate room for the indoor and outdoor units as well as ensure that there is enough space in your roof for the ducts themselves to be installed and configured properly. While there are many online calculators and formulas for determining the right size air conditioner for your home, it’s best to get a professional who specialises in ducted split systems in Melbourne to come to your home and do the measurements for you. A HVAC technician or air conditioner installer will know exactly where and what to measure and be able to plan any contingencies or see any possible issues that could arise from the installation well in advance.

Other Factors to Consider

Some other factors to consider when selecting a ducted split system are:

The Specific Spaces You’re Attempting to Cool

If the rooms you’re attempting to cool have high ceilings or obstructions, you may need to think about how this will impact the cooling effect that a split system will be able to output.


If your home is properly insulated, you may be able to get away with a split system that has a lower output. This is because adequate insulation will help to maintain the cooler temperature of the room and reduce the workload placed on the unit.

Running Costs

If running costs and energy bills are a concern, you may want to opt for the most energy efficient split system that falls within your budget. Long term maintenance costs may also be something you need to consider at this point in time too.
