Multi-Split or Single System Air Conditioning: Which is Right for You?

When it comes to cooling your home, there are two main options: Multi-Split or Single System Units. In this article, we’ll compare the two types of systems and help you decide which one is right for you.

What is a Multi-Split Unit?

With a Multi-Split Unit, you can cool multiple rooms with just a single outside unit, this can save space and can be boxed in or hidden from viewThe size of this unit can be calculated by the number of rooms you want to cool or heat. Each room will have its own inside unit and can be controlled on its own.

What is a Split System Air Conditioner

What is a Single Split System Air Conditioner?

This option is sometimes cheaper and consists of one outside unit to one inside unit.  Sometimes having four or five outside units.  It can be architecturally problematic and can take up quite a lot of space.

Pros and Cons of Central Air Conditioning


  • Can cool an entire home with one system
  • Provides consistent temperature throughout the home
  • Can filter out allergens and other contaminants


  • Expensive to install
  • Can be less energy-efficient than split systems
  • Requires ductwork, which can be expensive to repair or replace
Which Air Conditioning System Is Right for You

Pros and Cons of Split Systems


  • Can cool specific rooms or zones
  • Easy to install
  • Energy-efficient, especially for smaller spaces


  • May not provide consistent temperature throughout the home
  • Installation can be more expensive than window units
  • Multiple indoor units may not be aesthetically pleasing

Energy Efficiency Comparison: Central Air vs. Split System

Both multi-split and split systems can be energy-efficient, but multi-split systems are generally considered more efficient as you only use one compressor that will operate at the current demand.

Maintenance and Repair Costs

Maintenance and repair costs for multi-split systems and split systems can vary depending on the specific system and the level of maintenance required. Generally, however, split systems are easier and less expensive to maintain and repair because they have fewer components.


Whether you choose a multi-split system or a split system, be sure to keep up with regular maintenance to ensure your system runs efficiently and effectively. Read here for more information on other air conditioning types.
