How do I know what size air conditioner I need?

Open tab

Selecting the right portable air conditioner is essential. A portable air conditioner that’s too big will be a poor investment, one that’s too small will struggle to cool your room.

The capacity of an air conditioner to cool is measured in BTUs or kWh (kilo Watt hours). Bigger rooms need a portable air conditioner with a greater BTU rating. As a general rule, look at these room sizes:

18 metres square 4.24 x 4.24 metres (approx. 14 feet x 14 feet) - you’ll need an air conditioner with a rating of at least 7,000 BTUs to cool this room on a very warm summer day. 

24 metres square (approx. 16 feet x 16 feet) or approx. 4.9 metres x 4.9 metres - you’ll need an air conditioner with a rating of 9,000 BTUs to cool this room on a very warm summer day.

36 metres square (approx. 20 feet x 20 feet) or approximately 6 metres x 6 metres - you’ll need an air conditioner with a rating of 12,000 BTUs to cool this room on a very warm summer day.


You will need to increase the capacity of the air conditioner you buy if:

- The room gets very hot, e.g. a conservatory.

- Lots of people use the room at once e.g. a busy office

- You have multiple computer or heat generating equipment, e.g. a server room, offices

- You have very high ceilings

Why doesn’t my remote work?

Open tab

If your remote isn’t working properly or not working at all, there are a few steps you can follow. First, make sure you are no more than 5 meters away from the air conditioning unit and there are no obstacles between the remote control and the receiver. Also, check that the batteries don’t need replacing. If it’s still not working, try to unplug your unit’s power cable from the wall, wait at least ten seconds, and then plug it back in.

Can I extend the exhaust hose?

Open tab

We do not recommend extending the exhaust hose as this could impair the performance of your air conditioner. Instead, place your appliance nearer a window for venting.

Will my air conditioner cool more than one room at once?

Open tab

Portable air conditioners are designed to cool one room at a time. If you want to cool a different room, your unit is on wheels and can be moved smoothly to a new location.

Why isn’t my room cooling down?

Open tab

If your room doesn’t cool as you expect, follow these recommendations:

- Make sure your unit is in air conditioning mode and that the exhaust hose is attached.

- Check that the exhaust hose is not blocked, nor that the filters are clogged.

- Never rest objects of any kind on the air conditioner.

- Protect the room from direct exposure to the sun by partially closing curtains and/or blinds to make the appliance much more economical to run.

- Make sure your room does not contain any heat sources or open windows and doors.*

*In general, it is recommended that doors and windows remain closed at all times to get the full benefit from your air conditioner. The only exception is when the appliance is installed through a hole in the wall. In this case, it is recommended that you leave a slight draught through a door or window to guarantee correct ventilation.

What are BTUs and kWh and why are these metrics important?

Open tab

BTUs a unit of measurement of the power used by air conditioning units in the UK and the USA, designating British Thermal Units. This is the measure of the amount of heat needed to raise the of temperature of one pound of liquid water by one degree from 60° to 61° Fahrenheit, while maintaining a constant pressure. Another common measurement is kWh (kilo Watt hours) - and the power of all our air conditioners is given in both kWh and BTUs.

The number of BTUs required from an air conditioner should also take into account two key factors:

the size of the room the amount of heat being produced by people and machines within the space (remember to include ceiling heights in your assessments)

Another thing to consider is window size and the direction in which the window faces. The light received into a room is a significant factor in the temperature the room maintains. For example, South-facing conservatories can get very warm and will require a more powerful air conditioner than their area or volume would suggest.

We advise purchasing an air conditioner with a minimum output 8000 BTUs as this is the minimum BTUs required to cool a small room (18sq/m) on a hot day. Medium rooms (24sq/m) need around 9,000 BTUs and larger rooms and office spaces (36sq/m) require at least 10,500 BTUs.

Why doesn’t my Pinguino start as soon as I turn it on?

Open tab

Every air conditioning unit contains a safety device which delays operation of the air conditioner while checks are performed. Please wait three minutes and air conditioner will operate as normal once all checks have been performed.

Why can I smell a particular odour in the room when I run my air conditioner?

Open tab

If you can smell an odour in the room, that might be because the air purifying filters are clogged. Make sure you clean or replace the filters as soon as possible.

The alarm light came on. What should I do?

Open tab

Normally, the alarm light comes on when the tank inside the appliance is full. You should simply empty the tank.

How do I maintain my De’Longhi Pinguino?

Open tab

De’Longhi Pinguinos are robust and long-lasting. Here’s how to get the most out of them for years to come:


You can keep the external body of your air conditioner clean with a simple damp cloth. As this is an electrical appliance, please do not wash down and always turn the appliance off and remove the plug from the wall before cleaning. Do not use solvents or cleaning products.

The air filter helps remove harmful pollutants from your home or office and should be washed once a week to maintain hygiene and efficient operation. You can do this by turning off the appliance, unplugging and popping out the filter. Once out, the filter can be vacuumed or washed and rinsed in lukewarm water. Please let the filter dry naturally before returning it to the air conditioner.


If the weather turns colder and you want to store your De’Longhi Pinguino, then first you will need to drain the appliance of any residual water. This takes moments: simply remove the cap and let any water flow out into a bowl. Once completely empty, replace the cap.

It’s a good idea to also clean the filter before you roll your Pinguino in to a cupboard or garage. Please do not store your Pinguino by covering it with a plastic bag.
