Overview Of The Best Portable Air Conditioning Units In 2018

The Best Air Conditioning Systems For Home Use Reviewed


One of the best home air conditioning systems is this De'Longhi. It features a compact 30kg body with a sleek white finish. The body comes fitted with caster wheels and side carry handles for easy transportation.

This stylish air conditioner boasts from a few great features. Usually portable air conditioners are known for consuming a lot of electricity, however this model has been upgraded to prevent that from happening and to keep your bills down.

Alongside the above it comes with three speed settings, meaning it has a quite mode for when you are trying to sleep at night!

We have listed a couple more features below, however we would highly recommend checking it out.


  • Lightweight and compact design makes it ideal for use in small rooms
  • Easy to use and maintain with remote control
  • Very energy efficient, rated A


  • It is one of the more expensive models on the market, however the results in which the unit produces combats this


The Dyson AM09 is one of the best sellers on the market today, and it really is easy to see why. Although technically not "labelled" as an air conditioner, it does everything one does and more.

To start with the weight of this product is an astonishingly light 3.9kg, coming in way under that of its competitors. At full power the unit only reaches 65 decibels which is also incredible, compared to its competitors.

Due to the range of this unit and the wide projection, it is able to cool or even heat a room to your desired temperature in minutes.


  • Fast cooling and heating of rooms
  • Easy to control and maintain thanks to features that automatically monitor performance
  • Lightweight compared to competitors


  • Doesn't remove water from the air


The Ignex is a packaged central air conditioner that’s ideal for cooling single rooms. It has a cooling capacity which will cool even the largest room in your house fairly quickly. This air conditioner comes in a sleek white coloured body with a built in control panel. The control panel allows you to make any necessary settings to get quick results from the unit.

A remote control also makes it easy to make the necessary changes off board. Being a portable unit, it comes in at a supprising 8.8kg which is the lightest model on the market. If that weight doesn't make it portable for you, the fitted caster wheels should do the trick. 

The Ignex air conditioner features a 3 speed turbo fan with sleep mode functionality. This gives you more control over the unit’s performance and will help make sure you get a good nights sleep throughout these very clammy hot nights.


  • Compact and highly portable design doesn’t need special installation process
  • Easy to operate and maintain
  • Space saving design makes it easy to use inside rooms


  • Doesn't remove moisture from the air


If we were to pick one of the three above to be crowned kings, it would have to be the De'Longhi. The other two are great and are more than capable of doing the job, but we feel the features of the De'Longhi and it's reputable brand name for this type of product just nudge it over the finish line so to speak first for us.

A Mini Guide To Central Air Conditioners And How They Work

Central air conditioners differ from your portable or window installed air conditioners in terms of their size and efficiency. Central ACs are usually larger and are designed to cool and dehumidify entire buildings.

The best air conditioning systems work more or less the same way. They draw in cool air from outside and distribute it indoors. At the same time, warm air from within the house is collected and directed outwards.

To achieve this, the central AC includes different parts like fans, compressor, refrigerant, piping/ducts, expansion device and evaporator coils. The refrigerant collects and releases heat and moisture from air as it moves along the piping.

Types Of Central Air Conditioners

The best central ac units are either split systems or packaged systems.

Split central air conditioners are comprised of two main units, (outdoor and indoor) connected by a network of pipes. The outdoor unit contains the compressor, condenser and expansion valve while the indoor unit contains the evaporator coil.

Packaged central ACs on the other hand have all their components housed in a single unit that’s placed outside. Packaged central air conditioners come fitted with water or air cooled condensers.

What To Consider When Buying The Best Home Air Conditioning Systems

Energy Efficiency

A new central AC installation can see your monthly electricity bill rise significantly. Luckily for you, today’s air conditioners are being built to consume less energy while at the same time being highly efficient compared to older units. You can easily know your new air conditioners energy efficiency by looking at its Seasonal Energy Efficiency Ratio (SEER) or its Energy Efficiency Ratio (EER). A higher SEER rating indicates that the unit is highly energy efficient. In other instances where SEER and EER aren’t provided, you can check the cooling and heating capacity which is usually given in kW or BTU.

Ease Of Installation And Maintenance

Some of the best air conditioning units are quite difficult to install and maintain. Some of the factors that determine whether a unit is easy to install and maintain include its size, weight, features it has and whether it’s a split or packaged air conditioner. Packaged units are considered easier to install and maintain.

Ease Of Operation

The best residential ac units are designed to be easy to operate. Many of these appliances include well designed control panels and easy programmability which allows them to turn on and off depending on the settings you have chosen. Other features that make modern air conditioners easy to operate include variable fan speeds and remote control operation.

Brand And Warranty

Central air conditioners can be expensive to install and maintain. You’ll want to buy a unit from a reputable brand which offers a favourable warranty policy.
