How Does a Split System Air Conditioner Work? Everything You Need to Know

When it comes to cooling, there are two main options: the traditional central air conditioner and the split system air conditioner. The latter is becoming more popular as people seek ways to save money without compromising quality.

What Is a Split System Air Conditioner?

A split system air conditioner is an appliance that cools and dehumidifies the air in a room. It’s made up of two components: a condenser unit, which you can place outside your home, and an indoor unit, which you can have inside your home.

How Does a Split System Air Conditioner Work

As we have seen, a split system air conditioner is a conditioning unit that uses two different refrigerants. The first refrigerant is used to cool the indoor fan coil, while the second refrigerant is used to cool the outdoor compressor coil.

The outdoor compressor coil converts heat into compressed gas, which then travels through pipes in your home and out into an outdoor unit. It converts to liquid at high pressures of around 1,000 pounds per square inch.

This process helps reduce heat transfer back into your home during winter when it is freezing. On the other hand, the split system air conditioner does not allow for temperatures low enough to cause frost or condensation to form on your windows.

What Is the Difference Between Ducted and Ductless Split System Air Conditioners?

Here are some notable differences between ducted and ductless Split System Air Conditioners.

•    Ducted air conditioners are connected to a central ducting system, while ductless air conditioners have a built-in outdoor condenser unit.

•    Ducted systems are more expensive than ductless ones because of their complexity.

•    If your home has high ceilings (over 12 feet), you should consider purchasing a ducted split system air conditioner.

Why Should You Buy a Split System Air Conditioner?

Split System Air Conditioners are:

Cost Efficient

If you want to use the air conditioner in your home, but don’t want to pay for electricity and heating bills, a split system AC may be suitable for you. It’s cheaper than buying an entire window unit, and you can install it in walls or ceilings as well as floors and external walls.


If you have an old ceiling fan that doesn’t move much air anymore, you could install this type of system instead. This way, even if there aren’t many fans in your room, there will still be some ventilation. This is thanks to the split system’s ability to circulate hot air around wherever it needs cooling most.

The same goes for installing one within a floor area. Sometimes people prefer having their rooms cool down faster than usual due to how busy they are with work or other activities outside the home.


Split system air conditioners are the most used type of air conditioning worldwide. Thanks to this post, you may now answer the question, “How does a split system air conditioner work?” You can also tell that it is extremely efficient, dependable, and inexpensive. This conditioner will meet all of your needs.
