Are Mini-Splits Worth It?

Have you been hearing a lot about ductless mini-split air conditioning units? If you have, you may be wondering if they are any good. Perhaps it is time for your next AC replacement, and you are considering a ductless air conditioner. We are here to discuss whether mini-splits are worth it.

Pros of Mini-Splits

Quick and Simple Installation

If you live in a home without ductwork, a mini-split system will cut out the need to install ductwork. This makes it easy to install. Having ductwork installed can be expensive and time-consuming. With a ductless unit, all you need is a small hole in your wall to connect the indoor and outdoor unit. 

Improved Energy Efficiency and Indoor Air Quality

Ductless systems are much more energy efficient than central AC units since they don’t lose cool air in lengthy ducts. Ducts can also become worn out and dirty, which usually increases your energy bill and decreases your indoor air quality. 

Better Zone Control

Each mini-split unit is made to cool a small area. This means that it has automatic zone control where you can control the temperature of each room since each unit will come with its own thermostat.

Useful for Renovations

If you are planning to add on to your home, a ductless unit is perfect for you. This means that you won’t have to add ductwork to your newly renovated room. All you would have to do is install another separate unit in that room. Mini-splits are also versatile with where they can be mounted.

Cons of Mini-Splits

The Cost

Unfortunately, it costs slightly more to install a mini-split system than central air conditioning. The cost will also increase with each unit you add on. The more rooms you have, the more expensive it gets. 


Each room would need an indoor unit which is quite bulky, unlike central AC which has a discreet vent in each room. The shape and style of the mini-split units may clash with your home’s design. 

Higher Maintenance

With central AC units, it is necessary to change your air filter every couple of months or so. However, with a mini-split, this filter needs to be changed monthly for it to cool your home efficiently. 

Lower Performance in Harsh Temperatures 

Ductless systems are ideal for areas with moderate climates. They lose their efficiency when temperatures soar above 95° F. If you live in an area with scorching summers, this may not be the best option. 

Mini-Splits vs Central Air Conditioning

If you have a larger home that already has ductwork, a central AC system would benefit your home. In addition to that, if you have multiple rooms, it can become more expensive to install mini-split systems. 

Are Mini Splits Worth It for Heating?

Mini-splits can provide heating as well as cooling. This means that you only need one HVAC system instead of an AC unit and a furnace. However, as with its cooling performance, ductless units won’t heat your home efficiently when temperatures drop below freezing.
