When you live in a small space or apartment, keeping cool during summer can be a challenge. Standard cooling systems may be too large, expensive or inefficient for compact living environments. The good news is that there are air conditioners specifically designed for smaller spaces, offering comfort without taking up too much room or running up your energy bill.
Whether you’re renting a studio flat or living in a small townhouse, choosing the right system is essential. Here’s a closer look at the best types of air conditioners for small spaces and what makes them stand out.
Portable Air Conditioners: Flexibility and Simplicity
Portable air conditioners are one of the most popular options for renters and those with limited space. These units are freestanding and can be moved from room to room, making them a practical choice for apartments.
A portable unit typically vents through a window using a simple hose attachment. This means no need for permanent installation, which is ideal for those who can’t make changes to their living space. They’re also easy to store when not in use.
Modern portable air conditioners often come with built-in dehumidifiers and programmable timers, allowing you to maintain comfort while managing power use. While not as powerful as some fixed units, they provide reliable cooling for bedrooms, small living areas and offices.
Window Air Conditioners: Efficient and Space-Saving
If your apartment allows for it, a window air conditioner is a great choice. These units sit directly in a window frame and cool the room without taking up valuable floor space. They’re efficient, relatively affordable and ideal for cooling single rooms.
Many newer window models are quieter and more energy-efficient than older versions. Some also offer smart features like Wi-Fi connectivity, allowing you to control the unit with your smartphone or voice assistant.
It’s important to check with your landlord or strata management before installing one, as some buildings have restrictions on window-mounted units. When allowed, they’re one of the best air conditioners for small apartments with consistent cooling needs.
Split System Air Conditioners: Quiet and Powerful
Split system air conditioners are a common choice in many Australian homes and are becoming more popular in compact spaces too. These systems consist of an indoor wall-mounted unit connected to an outdoor compressor. They provide powerful, quiet and efficient cooling without the need for ducts.
Though installation is more complex and may require professional help, split systems are a long-term solution. Many models also offer reverse cycle heating, giving year-round climate control. They’re perfect for apartment dwellers who own their units or have landlord approval for installation.
Modern split systems come in sleek, compact designs that won’t clutter your walls. They also tend to be more energy-efficient than portable or window units, helping you save on electricity in the long run.
Multi-Split Systems for More than One Room
For those in small townhouses or multi-room apartments, a multi-split system might be the best option. These systems use a single outdoor unit to power multiple indoor units, each installed in a different room.
This setup provides individual control of temperatures in different areas, which adds flexibility and comfort. While it’s more expensive upfront, it reduces the need for several separate units and can lead to long-term savings on energy and maintenance.
Multi-split systems are especially useful if your small space includes an upstairs area or a larger open-plan layout.
Features to Consider for Small Space Cooling
When choosing air conditioners for a small apartment or home, size and power aren’t the only things that matter. Several other features make a big difference in comfort and efficiency.
Energy rating is important—look for models with high star ratings to reduce running costs. Noise level is another factor, especially in compact spaces where a loud unit can be distracting or affect sleep.
Smart functionality, such as app control, timers and eco modes, allows you to manage temperature without overusing power. Some models also include air purification filters, which can help improve indoor air quality, particularly important in city apartments.
Matching the Air Conditioner to the Room Size
Choosing the right capacity is key. A unit that’s too powerful will cool the room too quickly without properly dehumidifying, while one that’s too weak will struggle and use more energy.
For small bedrooms or offices under 20 square metres, a unit with around 2 to 2.5 kilowatts of cooling capacity should be sufficient. For larger living areas or open spaces up to 40 square metres, look for models in the 3.5 to 5 kilowatt range.
If you’re unsure, consult a licensed technician who can recommend the right size based on your apartment’s layout, insulation and orientation.
Small apartments and homes require smart choices when it comes to climate control. Luckily, there are plenty of air conditioners on the market tailored to compact spaces. From portable and window units to more permanent split systems, there’s a solution to suit every need and budget.
With rising temperatures and more people living in apartments, investing in the right air conditioning system can make a big difference in day-to-day comfort. Always consider your space limitations, building regulations and energy efficiency when making a decision.
By choosing wisely, you can stay cool through summer without compromising space, style or your power bill.
