A mini-split AC system is a kind of HVAC unit that does not need ductwork. While central air HVAC systems provide air conditioning throughout the whole building, mini-splits service specific rooms or zones. Both systems have an indoor and outdoor unit, though for mini-splits, each zone requires an individual indoor unit. There are advantages and disadvantages to mini split AC systems, just as there are to central air. By learning more about these pros and cons, you will be better equipped to decide which kind of AC unit works best for you and your home.

The Pros of Mini-Split AC

There are many reasons why mini-split AC systems are a very popular HVAC option. Here are a few of them:

  • Easy to install – Mini-splits are ductless, which makes the installation process far simpler and quicker. The indoor and outdoor units do still need to be connected, but this only requires a small hole to route the piping. Central air, which requires the ductwork, is a much more invasive process that involves more labor, parts, and construction.
  • Energy efficient – Due to the ductless nature of mini-splits, there is less loss of conditioned air to leaks in faulty ducts. Additionally, because mini-splits are zoned to specific areas, you can heat or cool a specific room without using the same amount of energy on the areas you otherwise wouldn’t need to heat/cool.
  • Cost efficient for the long-term – The high efficiency of mini-splits means that in the long run, you can save a lot of money on your energy bills.
  • Quiet – Unlike the sometimes noisy central air AC systems, mini-splits are nearly silent. The ductless system operates with quiet fans, which offer less distracting sounds than the typical system with ducts.
  • Zoning – Because mini-splits are individual units for specific areas, each unit services its designated zone. This means that the system is more targeted, providing different temperatures depending on the desired result for each area.

The Cons of Mini-Split Ac

While there are many benefits involved with mini-split AC, there are also some disadvantages. They include the following:

  • Clearly visible – Unlike a central air system with ducts in the walls and ceiling, the mini-split system requires an external, visible unit. Some don’t like the way these indoor handlers look in their homes. 
  • Takes up space – Mini splits aren’t absolutely huge, but they definitely take up space on the wall of their designated area. There are some that prefer the usage of internal space provided by central air rather than the external mini-split AC system.
  • High installation cost – While more cost-efficient in the long-run because of energy efficiency, mini-splits are expensive to install. The cost depends on the number of rooms that need units, as well as the size and type of the unit itself. It can be much more intimidating to pay the initial, higher cost of a mini-split system. Mini-splits are usually about 30% more expensive than central air with existing ductwork.
  • Less efficient ventilation – Mini-splits are more energy efficient, but they are comparatively lacking in ventilation efficiency. They only circulate and filter the indoor air of their designated areas, while central air units bring in fresh outdoor air and circulate the air of the entire home.
  • Requires more maintenance – Most experts suggest that typical central air systems need routine maintenance twice a year. However, mini-splits require more frequent maintenance. The reusable filter requires cleaning about once a month.
