The Best Split-System Air Conditioners
Split-system air conditioners are an adequate way to chill your place during hot days.
These systems work like whole-house HVAC systems but are designed to cool one room.
The split-system air conditioner has one unit outside for extracting the warm air from inside the house, and the other unit indoors, for blowing cool air into the room.
The technology behind the split-system performance is refrigeration.
Installment of the split-system air conditioner is a complicated process and you will need to hire a professional to do it properly.
Every split-system air conditioner has different specifications, so before you buy yourself one, make sure that you understand its effects, maintenance, and power usage.
Here are the top 10 split-system air conditioners with all their pros and cons.

Split-System Air Conditioners Buying Guide
Split-system air conditioners are the most popular type of air conditioners.
People choose it because of its versatility, capacity, and durability.
However, if you want to get yourself a split-system air conditioner, there are a few things to discuss.
Choosing a suitable air-conditioner for your home will ensure the best performance, smaller costs, and high efficiency.
Before we move on to every significant aspect of it, let’s sort out a few different types of air conditioners to make sure you know what you are getting.
Air Conditioners Types
The most proper type for a house is reverse-cycle air conditioners.
The reverse-cycle means that an air conditioner can cool and heat.
However, if you live somewhere where you don’t need heating because of the warm climate, choose only the cooling device.
Those are cheaper than reverse-cycle devices.
The split-system consists of two or more elements, outdoor and indoor.
Split-system Type
You connect one outdoor unit with the one indoor unit with pipes.
The refrigerant gas is inside those pipes. For the proper installment, it is best to hire a professional.
The split-system type is suitable for adjusting the temperature in only one room.
The prices vary, but the price range is usually from $500 to $700.
The maintenance is also different for all systems, but you will get all the necessary instructions in the manual.
Multi-split
What differentiates the multi-split system is the number of indoor units.
There is one outdoor unit that you can connect with two or more indoor assemblies. Therefore, you get cooling or heating in more than one room.
The package usually includes remote controls for each indoor unit. The price range is similar to the split-system type.
Ducted
The ducted air conditioner type is getting popular because of the straightforward installment.
It consists of a central unit which is connected to the air outlets and sensors in every room with air ducts.
If you choose the ducted type, you can cool or heat your entire house.
The price range is on the higher end.
Size
To determine the right volume of your air conditioner, you will have to know your room size.
The discrepancy between the capacity and the room size may result in undesired temperature and higher costs.
For example, if your air conditioner is too powerful, it will affect the humidity and the device’s durability.
On the other hand, if you have a large room, and your air conditioner isn’t powerful enough, it will have to operate for long hours.
The result is dry air, higher costs and not very much of a difference.
Here is the guide for choosing the right capacity air conditioner:
Room size up to 20 sq m – 2-2.5 kW capacity
Room size20-40 sq m – 2.5-5 kW capacity
Room size 40-60 sq m – 4-6 kW capacity
Room size 60–80 sq m – 5-7 kW capacity
Room size 80+ sq m – 6-9 Kw capacity
Noise Level
Most of the split air conditioners produce noise while running.
Determining whether the noise will bother you depends on where you want to put the air conditioner.
For comparison, the vacuum cleaner produces noise around 70-80 dBA.
Therefore, a suitable noise level for the living room could be around 50 dBA.
For the bedroom, you might want something quieter.
Other Features
The fan speed and operating modes are significant factors to consider.
Always check for air conditioners with more speeds, from high to low fan speed.
For example, the high-speed mode is proper for a quick cooling effect, but air conditioners are louder when running on high speed.
Low speed is the quiet operating mode, for smooth and gradual temperature regulation.
Modes
There are a few useful modes to check for when buying an air conditioner.
Automatic mode detects the mode that can work to preserve the present room conditions.
Heating and cooling modes pump heat from outside and opposite.
Dry mode dehumidifies the air and the fan provides the breeze without cooling or heating effect.
Economy mode is very useful if you want to keep track of your power consumption.
It controls the temperature using different technologies and reduces power consumption at the same time.
Energy-efficiency
When it comes to power consumption and costs of air conditioner, you should look for units that are Energy-star certified.
Energy star certification is the label that the government gives to the electrical products that show high performance, save money and energy.
So, you wouldn’t have to calculate power consumption by yourself.
Maintenance
Because you will spend a lot of time in the rooms with air-conditioner it is important to learn more about maintenance.
The self-cleaning mode is useful because the air-conditioner can remove allergens and health-hazardous from the air.
However, if the filters aren’t clean, there is a risk for dust and mold growing inside of it.
Before you buy a split system check how often you should replace the filters and what are the prices, etc.
The Position of the Air Conditioner
Check for the indoor and outdoor space left for the air conditioner.
If you don’t have enough wall space for an air conditioner unit, you will have to change the room layout.
Always measure the wall space you have and compare it with device size.
The proper position ensures high performance.
There are few positions for how you can install your air conditioner.
Check the device specifications to find out supported mounting positions.
Here are the basic mounting positions:
The high-wall position is the most natural.
Simply install the indoor unit high on the fall, and it will provide open and multi-directional airflow.
Floor-mounted is suitable for some rooms, which depends on the furniture in the room.
Cassette placement refers to the air conditioner unit set up in the ceiling.
Floor/Ceiling label means that you can either install the unit on the floor or the ceiling.
Operating on Extreme Temperatures
If you choose the reverse-cycle air conditioner and you plan to use it for heating, check whether the device has an automatic defrosting feature.
Also, the best air conditioners use powerful inverter DC motors to heat rooms during extremely cold weather conditions.
Pro-Tip
If you already know which device is suitable for you, buy it during spring or autumn.
During peak season, the prices can be higher, and most of the HVAC professionals are busy.
Do your research, find out the suitable capacity, desired additional features, and wait for spring to save some money.
Conclusion
If you don’t want to install an HVAC system, split system air conditioning units are the best choice.
When looking for a split air conditioner, look for those with ductless design, since those units are easier to install.
Sometimes, you can even do it by yourself.
The size of your room determines the cooling or heating power your air conditioner should have for the best performance.
Nowadays, you can buy smaller indoor units that are capable of cooling large spaces.
Most of the split system air conditioners have both cooling and heating option, but not all of them are suitable for usage on extreme temperatures.
Therefore, if your climate is known for extreme weather conditions, make sure to check if your air conditioner can support it.
