central AC vs split AC

If you’re in the market for a new air conditioning unit, you may be wondering if a central AC vs split AC is the better option for you. Both have their pros and cons, but ultimately the decision comes down to your specific needs and preferences.

In this blog post, we will discuss the differences between central and split AC units so that you can make an informed decision about which one is right for you.

How Do Mini-Split & Central Air Conditioners Work?

The physics behind central and mini-split air conditioners is the same. The system takes the warm air in, discharges the heat outside, and distributes the newly cooled air throughout the house, creating a calm and relaxing atmosphere. Let’s have a look at how these two air conditioners operate.

Central AC

A central air conditioner is a ducted system that circulates cold and hot air throughout your house via ducts and vents. A condenser, compressor, and air handling device make up the system.

Warm air is drawn from your home via return vents and sent to the air handler, where it is filtered and cooled. The outside unit, the condenser, supplies refrigerant, a cooling substance, to the evaporator coils of the indoor handler. Warm air from your home cools as it passes over the evaporator coils and distributes via ducts and supply vents.

If your home already has a duct system, it’s a good match for central air conditioning, but installing a central system in a home that doesn’t have one is also feasible.

Mini-Split AC

Mini-splits are an excellent solution for small spaces and residences. They’re comparable to window air conditioners since they chill only one room. They do, however, have a separate exterior unit, unlike window air conditioners.

Mini-split air conditioners differ from central air conditioners because they do not need ducting. A ductless mini-split heat pump system is a practical solution for houses without existing ducts or to cool extra spaces such as a garage or a shed since it does not need ducting.

The indoor unit of a mini-split system comprises an evaporator and a fan. The outdoor unit houses a compressor, condenser, and expansion valve.

The cold refrigerant is sent via copper tubing from the outdoor unit to the indoor one. The refrigerant evaporates as it passes through the expansion valve, cooling the air inside the room. The blower fan then distributes the cooled air.

Pros of Central AC

Using a central air conditioner has several advantages:

Lower Initial Cost

When comparing mini-split vs. central air systems, the cost is crucial. Central air costs 30% less upfront than mini-split systems, excluding ductwork installation. It is a cost-effective heating and cooling alternative if your property already has ductwork.

Clean Air Circulates Your Home

A central air conditioner has a filter that cleans the air before it’s circulated throughout your home. It means that you and your family can breathe easily, knowing that the air you’re breathing is clean and free of allergens and other contaminants.

Efficient Cooling

Central AC units cool large spaces quickly and efficiently. A central air conditioner is the best option to ensure that all rooms are evenly cooled if you have a big house.

Best for Larger Homes

Central air conditioners are suitable for larger homes because they can efficiently cool all rooms evenly. If you have a big house, central air is the best option to ensure comfort in every room.

Pros of Mini-Split AC

There are several advantages to using a mini-split air conditioner:

Flexible Placement

One of the main benefits of a mini-split system is that you can place it almost anywhere in your home. Since no ducts are required, you can put the indoor unit in any room. It is ideal if you want to cool a specific room or area of your home.

Quiet Operation

Another advantage of mini-split systems is that they operate quietly. You won’t have to worry about the outdoor unit making noise or disrupting your peace.

Efficient Cooling

Mini-split air conditioners cool small spaces quickly and efficiently. A mini-split system is the best option to ensure that all rooms are evenly cooled if you have a small home or apartment.

Best for Smaller Homes

Mini-split air conditioners are suitable for smaller homes because you can install them almost anywhere and don’t require ductwork. If you have a small house or apartment, mini-splits are the best option to ensure that every room is comfortable.

Fewer Costs Over Time

Although the initial cost of a mini-split is more than that of a central air conditioner of comparable capacity, don’t allow this to stop you from investing in a ductless system. It is more energy-efficient than a central air conditioner, which means you will save money in the long term. Furthermore, mini-splits are less expensive than central units for maintenance.


Now that you know the pros of central AC vs mini-split AC, which one should you choose? The answer depends on your needs and preferences. If you want a less expensive air conditioner to install and maintain, then a central AC unit is the way to go. However, a mini-split system is better if you need a more flexible and efficient cooling solution. Whichever air conditioner you choose, make sure to have it installed by a professional to ensure optimal performance.
