More and more people choose mini split air conditioners because of their cost-effectiveness. Sales charts back up this claim. The mini split AC industry is experiencing unprecedented levels of growth.  Here are the major reasons why:

  • Convenient installation process – tearing down and rebuilding is now a thing of the past.  The small pipes that connect the indoor and outdoor parts of a mini split air conditioner can easily fit in a 3-inch hole.
  • Improved air quality – the filtration system of ductless units effectively filter irritants, allergens and bacteria out of your space so expect better air quality indoors.
  • Less carbon footprint – refrigerants generally use chlorine, an element that harms the ozone layer. But mini split ACs use a refrigerant called R-410A, a much more environmentally friendly alternative.
  • Perfect for small spaces – unlike central air conditioning units, mini split air conditioners are not as large. They can practically be installed anywhere on a wall and they look far more classy!
  • More flexibility – you get to customize the installation process.  A mini split AC system can be hung on a wall or suspended from the ceiling.
  • It can save you a significant amount of money – several studies have shown that around 30% of energy consumption comes from duct losses.  Due to the fact that mini split ACs are without ducts, no duct losses can occur.  You can count on a cheaper energy bill when you utilize mini split ACs.
  • Better security – a window type aircon requires a hole big enough for a slim person to fit in.  Thieves may take advantage of the opportunity that this opening presents them. Unlike mini split air conditioners that usually require a 3-inch hole – absolutely no chance of break ins.
  • Zoning – these types of ACs split your home into different sections, and the sections are referred to as “zones”. Each zone will be given its own thermostat. This differs from old versions of ACs where whole spaces only received a single thermostat.  And because there are multiple thermostats, you can pick which specific areas you want to cool (or heat). This system saves a lot of energy resulting in a cheaper power bill.
  • Improved comfort levels during work and leisure – it has been proven that job performance increases when comfort levels are at a higher level.  And when we dislike the weather, our mood is gravely affected.  Air conditioners reduce the occurrence of that undesirable scenario and when our mood is great, we are almost always at our best behavior.  In short, mini split air conditioners rock!

How To Choose a Mini Split Air Conditioner

We’d like to end this “Best of” article with a comprehensive buyer’s guide.  Bookmark this page or take notes.  Split ACs are not very cheap so you would want to make your first (or next) purchase right.  Without further ado, here’s the checklist of the basic factors to consider when you are about to buy a mini split air conditioner for your small space:

Size of the room (or the space where you wish to place the AC)

If the room is too large, an AC might not have enough power to cool (or heat) the whole room.  You might be forced to keep the AC at its maximum power setting which will naturally consume more energy.  And the more energy that you consume, the more the power company will bill you.  On the other hand, if the room is too small, the whole room (or space) will easily cool but there will be a damp and humid sensation because the moisture will not have sufficient time to escape.

  • Small rooms under 25 sq.m needs a horsepower of 1.0 or less. The AC capacity should not be more than 10,550 kJ/hr.
  • Middle sized rooms range from 25 to 44 sq.m. and they need a horsepower of 1.5 or 2.0.  The AC capacity should range from 12,661 to 22,156 kJ/hr.
  • Large rooms range from 50 to 72 sq.m. and they need a horsepower of 2.5 or 3.0.  The AC capacity should range from 24,266 to 35,872 kJ/hr.

Generally, house rooms fit into the small and middle sized category.  Other than the size of the room, other elements should be considered such as the height of the ceiling, the number of people occupying the room and the climate.  A higher ceiling needs a higher capacity setting while a low capacity setting is enough for a room with a low ceiling.  In the same manner, more occupants in a room need a higher capacity setting, while a room with a low number of people needs a low capacity setting.  If you live in a place where the average temperature is 33°C / 90°F, then you will need to increase the capacity setting of the AC to achieve your desired cooling effect and so on.


It’ll be very hard to focus on your work or to manage a nap with a noisy background.  Most AC sellers display the noise that their ACs make in terms of decibels (dB).  Avoid those with high decibel ratings!  But fret not because the ACs we have recommended in this article will give optimal performance without being rowdy.

Specific Features

  • Mode Settings – there are ACs that cannot provide heat.  But some ACs can do it all: air conditioning + heating + dehumidification + ventilation.  If you live in a tropical country, then you won’t need an AC that provides heat.  Also, if you reside in a cold country, you wouldn’t need an AC that can only cool the room.  And last, if you are a citizen of a country with diverse seasons, then a multi purpose AC is best for you.
  • Timer – it’ll be very useful to have a mini split AC which features a timer.  Quick tip: Set your timer to turn on the AC 15 minutes before you arrive home from work and set your timer to turn off the AC deep into the night when you are sure that you’d already be asleep.
  • Energy Saving Features – more energy saved means more money saved!  Lookout for terms like ‘energy saving mode’, ‘sleep mode’ and ‘auto defrost’.  Prioritize the mini split AC systems which contain these additional settings.


Avoid fires and circuit breaks caused by faulty voltage readings.  If you are unfamiliar with the voltage requirement of your home or building, we highly recommend seeking out the help of a professional electrician.


Mini split air conditioners need expert installation.  Some sellers offer free installation, so pay attention to similar proposals.  Do not attempt to install it on your own, especially if you have no prior experience.  No matter how careful you may be, the machine might end up badly damaged and these incidents are generally not covered by warranties.


There are two types of compressors: the rotary and the inverter.  Less and less consumers look for the rotary compressor because inverter compressors can save bigger amounts of energy.  And as we’ve said more than once, more energy saved means more money saved!

To recap, here are the advantages of getting your own mini split AC:

  • Convenient installation process
  • Improved air quality
  • Less carbon footprint
  • Perfect for small spaces
  • More flexibility
  • It can save you a significant amount of money.
  • Better security
  • Zoning
  • Improved comfort levels during work and leisure

If you seek a safe and budget-friendly way to feel comfortable regardless of the weather, then grant yourself and your family a gift – choose to invest in a mini split air conditioner.  Split ACs are stylish, convenient and better for the environment.  I hope you found these reviews on the Best Mini Split Air Conditioners helpful and were able to find a mini split AC system perfect for your small space.
