What Features To Consider When Buying A Portable Air Conditioner

Before buying a mobile air conditioner have a think through the importance of the following features to best help find your perfect cooling unit!

BTU Cooling Capacity

As mentioned above this is the rate at which a unit can cool a room. The higher the BTU the bigger the room the compressor can cool it.

As a general rule of thumb, somewhere between 5k and 8k BTUs is sufficient for heating most bedrooms and lounges.

Dehumidifying Function

Many portable air conditioners have a 2 in 1 function, also acting as a dehumidifier. This means you’re buying an appliance that has uses all year round.

As is the case with any unit that performs many functions if you’re specifically looking for one then it’s best to get a unit that performs that function very well.

Another factor to build in if you’re considering one with a dehumidifying feature, is expelling water that it collects from the air. You may find with a air conditioner it’s placed near a window for the hose outlet but it may not be where you want the dehumidifier to go

Heating Function

Another function that some units have is heating – this can make the device useful all year round.

It really depends on your budget and needs – generally, if one function is super important, then we would recommend getting an appliance that is most suited to that one function.

Fan Function

Many mobile air conditioners have a fan only mode – so this doesn’t cool the room, it simply circulates the air around the room.

Noise Levels

Be aware that portable air conditioners are not quiet machines – and much less quiet than full AC units.

You’ll see on each review we’ve included the decibels value. The lower the the number the quieter the machine will be.

Night / Sleep Mode

Some portable air conditioner units will have a night mode.

This will mean the compressor won’t run as powerfully and the result is a quieter room while you’re trying to sleep.

Be aware though that it certainly won’t be inaudible. If you’re a light sleeper but really want it to stay on during the night, then I highly recommend a pair of ear plugs.

Another option is to run the air conditioner on max to get the room cool before bedtime.

Fan Speed

You’ll find that most units will have fan settings, usually around three.

This will enable you to cool the room at different speeds.

At night if you do run it then you can run at a lower fan speed, this will be quieter.

Timer

This can be very useful at night time. For example, you may cool the room down before you sleep and for the first hour. You can then have the unit switch off after a period of time once its cooled and this also means you won’t be woken up by the noise it makes.

If a timer is important I’d recommend getting one that has both a clock timer and a 24 hour setting. This gives you the most control.

Controls – Remote or Smartphone

Most portable air conditioners come with a remote so you can control it from the comfort of your sofa or bed. Some also can be operated via an app on your smart phone.

Portable Air Conditioner FAQs

What size portable air conditioner do I need?

Look out for what an air conditioner has in terms of BTU (British Thermal Unit). In effect the higher the number the quicker a unit can cool a room. So this figure will give you a rough guide on what sort of room it will best suited for.

An approximation for your intended room is to take the dimensions in feet and multiply by 5.

So for a room dimensions of 20 x 10 x 10 x 5 = 10,000. Keep an eye out for mobile air conditioner units that then have a BTU value of 10,000.

How much energy does a portable air conditioner use?

On average, a portable air conditioning unit uses 2.7 kilowatts of energy, and costs 44p an hour to run. Source: USWITCH.

With electricity costs potentially being high look out for the units with a decent energy efficiency ratio (EER).

This is the ratio between the power input (Watts) and the air conditioner’s BTU.

Another reference point is the energy class. This is self submitted by the manufacturer and goes from A to G. Do check user reviews, as these aren’t always 100% accurate.

I hope this list of the best portable air conditioners was helpful.
