Regrettably, working in an environment where there is constant harsh weather or hot climate makes one feel sick and uncomfortable. For this reason, you begin to think of how to purchase a cooling system.

A lot of options begin to come to mind, thinking of the type of cooling system that will solve the problem, right?. If that is your concern, worry not for this article will give you the right choice that you need.

All you need to do is to read further about split system air conditioners.

Join me as I dive into explaining more about the split system air conditioner.

Split System Air Conditioner Explained

Split System Air Conditioner Explained

A split system air conditioner is a cooling device designed to change the temperature of your homes or offices. It is an air conditioner that comprises two-component units; the inner and outer units.

These two-component units – the water or air-cool condensing unit and the air handling unit.

Also, these two parts connect to each other through a pipe or a duct. Unlike a central air conditioner that uses multiple ducts to connect to different rooms.

However, the indoor unit contains the evaporator coil which then connects the condenser coil of the outdoor unit to provide the cooling solution that you need.

To work effectively, you will have your installer position the outdoor unit on the exterior wall of the room where you wish to control the temperature.

However, the indoor unit then will have to be installed on the interior wall of the proposed room you wish to regulate its temperature.

This indoor unit consists of a cooling coil, a boaster, and an air filter – that enables the AC to work effectively.

The split system air conditioner works with a remote controller and as well fit with a heating pump facility. It, however, has a built-in timer and controller to perfect your experience while using it.

What is the Benefits of a Split System Air Conditioner?

What is the Benefits of a Split System Air Conditioner

It is always very important for one to ask what will I benefit from buying a specific product? Here in this article, I will be telling you what you ought to benefit from buying Split System Air Conditioner.

These includes:

  1. Its performance is quiet and cool. Its make lesser noise.
  2. It stand out to cool multiple rooms where you can have more indoor units connected to a single outdoor unit and still maintains a very good temperature despite covering a large room.
  3. Unlike every other air conditioners, the compressor and fan for the condenser are located outside the room and that stops the noise from occurring.
  4. Moreso, it is efficient and cost-effective. Even though, the cost of split system air conditioner is higher than that of window units AC, but due to the energy bills that other AC would consume, when professionally installed, buying a split system AC will worth it at the end.
  5. The split AC reduces electric billing when properly installed.
  6. It also increases the life span of the air conditioner.
  7. It also helps to keep the environment clean and lower your monthly power bill by using less energy.

Having said that, the subsequent heading will tell you how a split system air conditioner works. Please keep reading.

How does Split System Air Conditioner Work?

How does Split System Air Conditioner Work?

Every cooling system has different patterns in which it generates and exposes air. That is to say, a split system air conditioner works in a different way because of its component units; the indoor and outdoor units.

Therefore, read on while I briefly explain how it works.

The Evaporation Unit

The evaporator part of the AC absorbs heat/cold from the inside and then distributes cool/warm air in every part of the room.

At the same time, the evaporator absorbs heat/cold easily with the help of copper or aluminum metal. This evaporator is made with copper or aluminum metal.

The Compressor Unit

As the air conditioner is evaporating, the compressor moves the refrigerant around the evaporator and condenser coils, ensuring they pump or change gas when needed.

The Condensing Unit

After the heat from the evaporator absorbs, it then travels outside through the copper metal to the condenser unit.

However, it creates water both in heating and cooling modes. The indoor unit creates the cooling mode, while the heating mode generates through the outdoor unit.

So it removes the heat inside your house and transfers it outside. The refrigerant gets cold and recycles the process.

Therefore, the refrigerant line sets connected by copper tubes set each unit to its own temperature.

Finally, you may wish to know what makes it different from other air conditioners. Don’t be in a hurry yet, read below to find out.

Split System Air Conditioner Vs Other Air Conditioners?


Easy to Install

It is easier to install because it is ductless. Unlike traditional air conditioner that needs ductwork to be able to transfer air to the rooms.

Thinking of what is the ductwork? Ductwork is a metal tube used to distribute air from a heating or cooling system throughout your building.

Sometimes when the system is not properly installed, there may be a loss of energy due to heat exchange in the air duct system.

More so, the AC’s system performance is weakened if wrongly installed. This can make the AC develop a fault leading to the failure to function well.

Less Expensive

Split System Air Conditioner is more affordable and it cools faster in a home more than a central or traditional air conditioner. Even though they are attributed to a single room space as window AC, it cools at a higher capacity.

Easy to Maintain

Because of the basic remote control it usually comes with, it is easier to operate and maintain.

Positively, the indoor and outdoor unit of the split air conditioner makes the air conditioner less complicated and needs little or no servicing.

The only thing you need to do is to wash the filter frequently. Cleaning of the filter doesn’t require an expert, it can be done by you or anyone.

Overall, it is smaller and less noisy.

Other Types of Air Conditioner

Other type of Air condition

Air conditioners are not just one standard unit. Basically, there are a window unit AC and the central unit air conditioner.

Window Air Conditioner

The window unit AC is portable and has a quick cooling capacity. Unlike the split air conditioner that has two components, the window unit is incorporated as one unit AC.

However, this implies that the connecting pipes, heat-exchanging devices, and the compressor are all connected in one unit. It then controls the heat near it and throws it outside for more cooling temperature.

Furthermore, the window unit AC is mostly used in a single room because it has a reliant airflow. This means it can’t travel far to cool other spaces or rooms through the wall.

One of the advantages of this type of AC is the low price and easy installation. You can equally install it by yourself if you are capable enough to handle it.

For your guide to install the window AC, all you need to do is to follow these easy steps.

First, open or remove the windowpane where it will be installed, insert the AC into the space while the controller is facing you.

Move on to screw it into the place and then proceed to open the AC side curtains to cover any unused space. Finally, plug your AC and allow it to cool down the room.

Central Air Conditioner

Every AC has its own characteristics, this type of AC is common in cooling homes or offices very thoroughly.

It picks the evaporator and takes it through the refrigerator line set and releases it at the condenser unit.

To cool down a space it just needs to remove the heat in the space and throw it outside.

Generally, the central air conditioner can reach up to 22 seasonal energy efficiency ratios. Meaning, a cooling output of an air conditioner during a cooling season.

How to Install a Split System Air Conditioner.

How to Install a Split System Air Conditioner

There are different ways to install the two units.

Install the air handling unit (indoor) in the air-conditioned room, then install the condensing unit (outdoor) either in the engine room or outside but must be close to each other.

Indoor Installation

First, you need to secure a location on your interior wall to mount the indoor unit. An ideal place that is away from the sunlight and heat.

Choose where there is a stud to ensure the wall is strong enough to hold the weight of the unit.

It must be at least 3.3 feet away from the antennas and power. For instance, it should not be closer to the television, radio, or intercom space, etc.

Straightaway, check the connection of the inside units to connect the pipes from the inside to the outside unit.

Afterward, the engineer or the installer should measure the length and the type of pipe and connect the two units.

Overall, you should not forget to connect the pipe to the drainage and to the base of the interior unit.

Outdoor Installation

Install the outdoor unit in a wall that is strong enough to hold the weight. Avoid areas that are hot and places where there is so much movement.

Consequently, it is preferable you place it on a concrete block where there will be no damage. It should also be high enough to avoid water from flooding it.

Lastly, make sure the pipework is secured to the wall using clamps and screws to seal up the holes.

What to Consider before Purchasing a Split System Air Conditioner

Are you thinking of buying a split air conditioner for your offices or homes? If yes, chill and continue reading.

As much as you prefer a cool temperature to hot weather, there are still things you need to consider. However, a split air conditioner doesn’t work well in some places because of the following reasons.


Any air conditioner that doesn’t have a SEER rating of above 13 will not work properly in a room that is up to 616 square feet or more.

Therefore, a SEER rating that is higher than 13 and above is highly efficient and the cooling capacity is energy efficient.


A portable AC-like split system air conditioner may not go well in medium or large size rooms. If you are looking forward to cooling multiple rooms, but not really the whole house, it is better to buy a ducted system for effective cooling.

Therefore, to give a room of up to 616 square feet a comfortable temperature, the cooling capacity should be more than enough. If the room is well insulated.


If you can afford to pay for the purchase and the installation costs, you can purchase a split system air conditioner. It is very costlier compared to the window AC.

Therefore, most air conditioners require professional installation, meaning it may cost you more depending on the type of unit you choose.


Determining how you use your air conditioner is very important if you are looking for both cooling and heating AC for your home. Especially if you live in an environment where temperatures fluctuate.

Inverter Model or Reverse Cycle Unit

Purchasing an air conditioner also involves knowing the type of AC it is. Is it an inverter type or reverse cycle?

The inverter model doesn’t switch on and off frequently. The compressor speed is much different and better than the normal AC compressors.

This kind of unit compressor doesn’t need much stress, if not it will affect the electricity usage and may end up consuming a lot of energy if not properly managed.

However, the inverter type relatively operates on demand. Meaning that they speed up or down when it needs to and then set the temperature within a small period of time.

Finally, inverter AC’s seems to be more efficient than non-inverter models. This implies that the inverter type operates on-demand while the non-inverter runs in full power or switch-off mode.

Reverse Cycle Unit

On the other hand, the reverse cycle air conditioner has a higher capacity for cooling, both in summer and in winter. Although purchasing and installing cost is much higher, but they are the most effective AC to use.

Furthermore, modern technology has made it easier for us by creating some range of air conditioning features. However, most split system air conditioners have different features that improve efficiency.

Those features are found in reverse cycle AC, and they include a sleep mode, a dry or dehumidifier mode, and built-in sensors.

The dry mode helps to reduce excess humidity in the air. It also reduces the moisture in the air while still cooling your home and bringing back comfortability to your home.

Afterward, the built-in sensors regulate and determine when there are people in the room using the control panel. Then, the unit switches off if the room is empty.

Overall, during installation, you need a professional installer for every ductless system to avoid early dysfunction or failure of the air conditioner.

Lastly, there will be a need to look into the pros of the split system air conditioner, as well as talking about the cons.

The Pros and Cons of Split System Air Conditioner
