 Trustindex verifies that the original source of the review is Google. Absolutely outstanding service from ClimaChill, and especially from Scarlett.

From the moment I contacted the team, Scarlett went above and beyond to help me with my air conditioning unit. Her work ethic, professionalism and willingness to help were genuinely impressive. She was incredibly friendly, patient and knowledgeable, and made sure that my issue was dealt with properly rather than simply brushing it aside.

It’s rare to come across someone who clearly takes so much pride in their work and genuinely cares about giving customers a great experience. Scarlett is a real credit to ClimaChill and deserves recognition for the effort she puts in.

I wouldn’t hesitate to recommend ClimaChill to anyone, and if you’re lucky enough to deal with Scarlett, you know you’re in good hands

Portable air conditioners provide a flexible cooling solution for situations where permanent air conditioning is not practical. They are commonly used for temporary cooling, targeted temperature control, and environments where installation options are limited.

Portable air conditioning is ideal when:

Permanent installation is not possible

Temporary cooling is required

Additional cooling is needed during heatwaves

Specific rooms require temperature control

Cooling equipment or server rooms

Typical environments include:

Offices and meeting rooms

Schools and classrooms

Hospitals and healthcare facilities

Commercial buildings

Residential properties

Feature	Portable Air Conditioner	Installed Air Conditioning
Installation	No permanent installation required	Professional installation required
Mobility	Can be moved between rooms	Fixed location
Upfront Cost	Lower initial cost	Higher installation investment
Cooling Coverage	Single room cooling	Whole property or multi-room systems
Best Use Case	Temporary or flexible cooling	Permanent climate control

Portable air conditioners cool rooms using a refrigeration cycle similar to traditional systems.

The process works as follows:

Warm air is drawn into the unit
The air passes over cooling coils containing refrigerant
Heat is removed and expelled through an exhaust hose
Cooled air is circulated back into the room

Many modern units also recycle condensation water, improving energy efficiency and reducing maintenance.

Climachill’s portable air conditioners offer several advantages and are available in a range of cooling outputs. Our team can help you choose the correct capacity for your space.

No permanent installation required
Lower upfront cost than fixed systems
Flexible room-to-room cooling
Quick setup and immediate cooling
Ideal for temporary environments
For businesses, portable units can also provide backup cooling during system failures or peak temperatures.

12,000 BTU for small rooms and home offices
18,000 BTU for medium-sized rooms
30,000–50,000 BTU for commercial spaces and large environments

What is a portable air conditioner?: A portable air conditioner is a mobile cooling unit designed to cool individual rooms without permanent installation.
Do portable air conditioners need venting?: Yes. Most units require an exhaust hose that vents warm air through a window or wall outlet.
Are portable air conditioners suitable for offices?: Yes. Many businesses use portable air conditioners in offices, meeting rooms, and server rooms.

How energy efficient are portable air conditioners?: Modern units recycle condensation water and use efficient compressors to reduce energy consumption.
Can portable air conditioners cool large rooms?: Yes, depending on the BTU rating. Larger units can cool commercial spaces or large rooms.
Do portable air conditioners require professional installation?: No. Most units only require a power outlet and window ventilation.

Many thanks for carrying out such a quick and professional job here last week, we are pleased that we chose Climachill over the competition for our air-conditioning installation. As for your competitors, we chose Climachill not only because, on a like for like basis (5&7kw units) you were cheaper but because you came across as the most professional when you visited us initially to make the site survey and discuss our requirements.

Martin Smith

Sales Director, Ultimate Automation, Partridge Green

We would like to thank your company for the reliable service provided with our air conditioning systems over the last few years. The original purchase was handled smoothly and you have always been most accommodating whenever we have needed further assistance. During our recent renovation, your company was easy to contact, quick to respond and most helpful in relocating the equipment.

Jacqueline Noyes

Practice Manager, Ashley Road Dental Practice, Walton-on-Thames

After contacting several Air Conditioning Suppliers who failed to turn up, I managed to locate Climachill who carried out a site survey and installed the air conditioning to regulate the temperature in my server room, all within 21 days of the initial contact with minimal disruption. This included the installation of additional electrics to cope with the extra power draw from the 3 air conditioning units and the removal of a double glazed window for the triple extraction system. I have found Climachill’s service efficient and professional and have no hesitation in recommending them.

Steve Green

IT Manager, Crime Reduction Initiative, Brighton

From installation through to ongoing maintenance I have found all at Climachill to be most helpful and efficient in all of my dealings with them. We have had no issues whatsoever with our system that they installed and it has been extremely effective in managing costs both in summer and through the winter whilst keeping us cool and warm respectively.

Neil Sutherland

Managing Director, Neil Sutherland Estate & Letting Agents, Brighton

Climachill fitted full air conditioning to our office premises which is a converted barn in Glynde near Lewes. We received the highest level of service right through from them providing a very competitive quotation through to the complete installation. It has transformed our working environment when we end up with extreme temperatures at either end of the scale and so much so that I have installed an air conditioning system at my own house, again which Climachill have completed to an excellent standard.
