Selecting the right air conditioning system for your home or workplace can feel overwhelming. With so many options available, it’s natural to have a lot of questions:
What size unit do I need? How much noise will it make? How energy-efficient is it? Will it be powerful enough to cool or heat every room? These are just a few of the common concerns we hear from customers, and we’re here to help you find the ideal air conditioning solution for your space.
While most people are familiar with split systems and ducted systems, there are also other options like wall-mounted and portable units that may be better suited to your apartment, office, or specific room layout. Let’s explore the main types of heating, ventilation and air conditioning systems and the benefits of each to help you make an informed decision.
Types of Air Conditioners
Split System Air Conditioner
A split system is one of the most popular choices for residential homes. It consists of two main components: an indoor unit (the fan) and an outdoor unit (the compressor/condenser), which are connected by pipes and electrical wiring.
The main benefit of split system air conditioners is that they don’t require any ductwork to function; therefore, there is no need for a major air conditioning installation. A split system is one of the more popular types of air conditioners and is the ideal option if you want to cool down or heat up at least one large bedroom space.
A portable air conditioner would not be suitable for this environment. Split systems come in two parts: a fan and a condenser, which are located outside of your property, meaning you won’t hear any loud noises. For a quiet operating air conditioner, a split system is the perfect choice for your home.
Key Benefits:
- Ideal for single rooms or open-plan areas such as a living room or large bedroom.
- No ductwork is required, making installation simpler and less invasive.
- Quiet operation, as the noisier condenser unit is located outside.
- Available in models with reverse cycle functionality, allowing both heating and cooling year-round.
- Energy-efficient and easy to control with remotes or smart systems.
This system is perfect for homeowners wanting a long-term solution that provides powerful climate control without extensive renovations.
Ducted System Air Conditioner
If you’re looking for an unobtrusive, whole-home cooling or heating solution, a ducted system could be the way to go. This setup features a central unit installed in the roof space, which distributes air via a network of ducts and discreet ceiling vents. Ducted air conditioning systems are definitely the most minimalistic in appearance.
The air conditioning unit is completely hidden, and only the vents can be seen. It will then cool down or heat up multiple rooms at once. This system would be a great choice for an office space as it cannot be seen and will regulate an even temperature across multiple spaces.
Even though ducted systems are more expensive, they will reach your entire property rather than one or two rooms. There are also zone-ducted air conditioners, which allow you to change the temperature in different rooms.
Key Benefits:
- Aesthetic appeal – only the vents are visible in each room.
- Able to control the temperature across the entire property from a single system.
- Ideal for large homes or commercial spaces.
- Optional zoning capability allows different temperatures in different rooms or areas, increasing energy efficiency and comfort.
While ducted systems are more expensive upfront and require professional installation, they offer seamless performance and are particularly beneficial for multi-room applications where even temperature control is important.
Multi-Split System Air Conditioner
A multi-split system is a versatile option for properties with several rooms but limited outdoor space. It connects multiple indoor units (up to 6) to a single outdoor unit, allowing independent control of each room. Multi-systems are great for properties with multiple rooms.
They allow you to cool down or heat up multiple rooms at once or just one room at a time. Multi-systems come with one outdoor unit yet can operate up to 6 indoor air conditioners. The systems are highly efficient as they operate just one system.
Multi-systems are flexible to suit all residential and commercial spaces. You have control when using this type of air conditioner; it is the perfect option for your space.
Key Benefits:
- Energy-efficient – one outdoor unit supports several indoor units.
- Suitable for residential homes and small commercial setups.
- Allows room-by-room temperature control for greater flexibility.
- Great for renovations or when extending existing systems.
This type of system gives you all the benefits of a traditional split system but with the added advantage of serving multiple areas without installing numerous outdoor units.
Wall-Mounted Air Conditioner
Wall-mounted air conditioners are a subtype of split systems, typically designed for smaller rooms or specific zones. These are mounted high on a wall and are widely used in both residential and small commercial settings.
Wall-mounted air conditioners are one of the more common air conditioning systems. They are affordable and efficient to install. They are best suited for smaller rooms such as bedrooms, small apartments or small office spaces.
Larger rooms will need multiple wall-mounted air conditioners to sufficiently cool down or heat up your space. Powerful wall-mounted systems are typically used for industrial locations. However, they are very noisy and are not ideal for office spaces.
Key Benefits:
- Cost-effective and quick to install.
- Perfect for small bedrooms, apartments, or individual office rooms.
- Easy to maintain and operate.
- Available in a range of sizes to suit different room dimensions.
For larger areas, multiple wall units may be required. While powerful industrial models exist, they can be noisy and are not typically recommended for quiet environments like offices or bedrooms.
Portable Air Conditioner
If you’re renting or need a temporary cooling solution, a portable air conditioner could be a great fit. These units sit on the floor and can be moved from room to room as needed. Portable air conditioners require no permanent installation; all they need is a wall electrical outlet.
Portable air conditioners, just like their name they’re portable. You can move your air conditioner anywhere that is best suited for your needs. Portable air conditioners dehumidify your air, making it the perfect option for those with allergies. They may be the cheapest option; however, they are not the most effective.
Key Benefits:
- There is no permanent installation, just plug it into a power socket.
- Highly flexible and mobile.
- Some models include dehumidifiers, which are great for allergy sufferers.
- Ideal for small rooms, home offices, or occasional use.
While they’re usually the most affordable upfront, portable units are less efficient than fixed systems and tend to be noisier. They’re best suited for spot cooling or situations where other options aren’t feasible.
Which Air Conditioner is Right for You?
Finding the ideal air conditioning system depends largely on the size and function of your space. For large offices or commercial environments, a ducted system or a multi-split system typically offers the best solution. These options provide consistent, efficient temperature control throughout multiple rooms, ensuring a comfortable environment for everyone inside.
In residential homes, a split system is often the go-to choice for cooling or heating individual rooms or open-plan living spaces. However, if you’re looking to regulate the temperature across several rooms, a multi-split or ducted system might be more suitable, depending on your layout and budget.
For apartment dwellers or those in rental properties, wall-mounted air conditioners provide a practical and cost-effective option. They’re compact, easy to install, and capable of efficiently maintaining the temperature in smaller spaces. If you need something portable or temporary, perhaps while renting or moving, a portable air conditioner offers the flexibility to move it from room to room as needed.
For households or workplaces where individual temperature preferences vary, a zoned ducted system is a great solution. It allows you to set different temperatures in separate rooms so everyone stays comfortable without compromising on energy efficiency.
Let Us Help You Make the Right Choice
No two homes or workspaces are exactly the same, which is why it’s important to consider a few key factors before selecting an air conditioning system.
Think about how large the area is that you want to cool or heat, how frequently you’ll be using the system, and how much you’re willing to invest, not just in installation but also in ongoing running costs. It’s also worth considering your tolerance for noise and whether you prefer a more discreet or visually integrated system.
