A well-functioning heating and cooling system is crucial for maintaining comfort and energy efficiency in your home.
To ensure you make the best decision when purchasing a new AC, it’s essential to do your research and tick every box.
That’s exactly what this article is here to help you do.
Our heating and cooling checklist will cover everything you need to consider before buying a new air conditioning unit or heater.
From assessing your current system to choosing a qualified installer, we’ll cover it all.
The first step to buying a new AC is taking a look at your existing system (if you have one).
If your existing unit is 10 years old or older and is constantly breaking down, all while offering reduced heating and cooling performance, then it’s definitely time for a replacement.
Similarly, if your existing system isn’t very energy efficient, then it could be worth upgrading.
However, if this is the first time that your air conditioner has experienced problems and it’s in pretty good condition overall, then it might be cost-effective to repair it rather than replace it.
Another good reason to assess your current system is to determine what you will and won’t like about your new unit.
Maybe you want to switch from an AC that covers one room to a system that covers the whole home.
Perhaps your existing unit was always too noisy and you want to prioritise quiet operation.
Maybe you really like the remote control on your current unit and want to look for a system with the same or similar interface.
If you already have a separate heating system, maybe you just want a new air conditioner. And if you’ve already got a separate cooling system, maybe you just want a new heater. Or maybe you want a combined heating and cooling system in one.
Now that you’ve reflected on your current system, you can think specifically about what you need from a new heating and cooling unit.
Specifically, you need to calculate the size and heating/cooling capacity required for your home or business.
Determining the exact size and output you need from an air conditioner can be a pretty complex task, but generally speaking, here are the things you need to consider:
Now that you’ve considered your general needs, it’s time to get into specific system types, brands, and models.
Here are the main contenders to consider:
If you want heating and cooling from one system, then reverse cycle air conditioners are by far the best option.
Utilising heat pumps, these units boast up to 600% energy efficiency, which far outperforms other options on the market.
Whether you want climate control in one room or your whole home, these systems can deliver. Choose between ducted reverse cycle heating and cooling or reverse cycle split systems in Melbourne. Split systems (or ductless systems) combine an indoor unit and an outdoor unit while ducted systems replace the indoor unit with concealed ducts and sleek vents.
Both of these air conditioners are cooling-only systems, so they’re not appropriate if you’re also looking for a heater.
Evaporative coolers are ducted systems that can naturally cool your entire property. They are preferred by people who want to be able to keep their windows open and those who prioritise eco-friendly cooling. However, they don’t work as well on really humid days.
Refrigerated air conditioning units are usually ducted, but you can also buy cooling-only split systems that utilise refrigerated cooling technology. These units provide more precise and powerful cooling that works well even on humid days, so they’re preferred by anyone who wants to get the most from their AC. However, doors and windows must be kept shut during operation.
As the name suggests, these systems are both central air conditioners and heating-only options, so they’re only appropriate if that’s what you are looking for.
However, if you consider it ahead of time, you can implement add-on cooling at the same time or at a later date. This allows you to have a central air conditioning system that uses the same ducts as your gas heating.
Generally speaking, you’re better off getting a reverse cycle split system if you want space heating, as these units also come with air conditioning and offer greater heating capacity.
However, if you want an aesthetic centrepiece in your room that also doubles as a heater, a gas log fire is a good option.
Hydronic heating is Melbourne’s most unique heating option. Unlike the most common types of AC, these units use hot water rather than hot air to warm the home. Hot water is delivered to towel rails, trench convectors, radiator panels, underfloor heating systems and more to warm these surfaces and create radiant heat in the home.
Hydronic heating can be installed in one room or the whole home, but it’s often best left for new builds as the installation process can be complex. Cooling may also be available through hydronic systems.
No matter which type of air conditioner you choose, it’s essential to select an energy-efficient system.
Luckily, Australia’s energy rating system is easy to understand. Every heating and cooling appliance you look at should have a label with an energy star rating and energy consumption information.
The more stars your appliance has, the less energy it will use and the more you will save on energy bills. Lower power consumption also means a more environmentally friendly air conditioner.
The energy consumption information lists energy consumption in kilowatt-hours (kWh). This number can be used to easily compare AC models of all sizes. The fewer kWh consumed, the better!
These days, heaters and air conditioners come with a wide range of features. Some key functions and additional features to consider include:
Some of the leading heating and cooling brands in Australia include:
Different types of air conditioners will vary in price depending on the type, brand, and features.
Average costs for the supply and installation of a single split system may be around $2000, while a full ducted unit with multiple outlets can cost $10,000 or more.
While energy-efficient models may have a higher upfront cost, they can provide long-term cost savings through reduced energy consumption.

Professional air conditioning installation is critical for optimal performance and warranty protection of your new heating and cooling system.
To find a reputable and qualified air conditioning installer in your area, ask for recommendations from friends, family, or online reviews. Additionally, ensure your installer provides regular maintenance and servicing to keep your new AC system running efficiently and prolong its lifespan.
Purchasing a new heating and cooling system is a significant investment, so it’s essential to thoroughly research and consider your options before making a decision.
Use this heating and cooling checklist as a guide to ensure you select a well-suited, energy-efficient AC system that will provide increased comfort and cost savings for your home.
