What Is Installed Air Conditioning?

Installed air conditioning, sometimes called a split system or wall-mounted air conditioning, consists of an indoor unit fixed to a wall and an outdoor compressor unit. The two are connected by refrigerant pipework and electrical cabling, installed by a qualified F-Gas engineer.

Unlike portable units, installed systems do not require a hose or floor space. They are quieter, more powerful and significantly more energy-efficient for long-term use. Most modern split systems also provide heating as well as cooling, making them suitable for year-round climate control.

 

Who Is Installed Air Conditioning For?

Installed air conditioning is suitable for homeowners, landlords, businesses and commercial property managers who need reliable, efficient and permanent temperature control. It is the right choice when:

You need consistent cooling or heating in a fixed space throughout the year.

You want a discreet, wall-mounted solution that does not take up floor space.

You are cooling a room or building where a portable unit is not practical.

You want the most energy-efficient solution for long-term running costs.

You need to maintain a specific temperature for regulatory, comfort or equipment reasons.

 

Domestic vs Commercial Installation

Residential installation typically involves one or more wall-mounted split systems in bedrooms, living rooms, home offices or conservatories. Systems are sized to the room and selected for quiet operation and aesthetic fit with the home.

Commercial installation covers a wider range of environments including offices, retail premises, restaurants, hotels, schools, dental surgeries and server rooms. Commercial systems are designed for heavier use, longer running hours and often larger or more complex spaces. We work with facilities managers, contractors and business owners to specify the right system for each environment.

 

Installed Air Conditioning vs Portable Air Conditioning

Both options cool a space effectively, but they serve different needs.

Installed air conditioning is more powerful, quieter, more energy-efficient and better suited to permanent, long-term use. It requires professional installation by an F-Gas certified engineer and cannot be moved between locations.

Portable air conditioning requires no installation, can be deployed immediately and moved between spaces as needed. It is better suited to temporary cooling, emergency situations, spaces without an external wall or environments where permanent installation is not practical or permitted.

If you are unsure which solution is right for your situation, our team can advise based on your property, budget and usage requirements.

 

Typical Installation Process

1. Initial enquiry – Contact Climachill to discuss your requirements, property type and location.

2. Site survey – One of our engineers visits to assess the space, identify the best unit positions, plan the pipework route and confirm the electrical requirements.

3. System recommendation – We recommend the most suitable system based on your room size, usage, budget and energy efficiency priorities.

4. Installation – Our F-Gas certified engineers install the indoor and outdoor units, run the refrigerant pipework and commission the system. Most residential installations are completed in a single day.

5. Handover and demonstration – We explain how to operate the system, set temperatures and use any smart controls or scheduling features.

6. Ongoing support – Climachill provides servicing, maintenance and breakdown support after installation. We recommend annual servicing to maintain efficiency and manufacturer warranty compliance.

Air Conditioning Installation FAQs

How long does air conditioning installation take?

Most residential installations are completed in a single day. Commercial installations vary depending on the size and complexity of the project. We will give you a realistic timeframe during the survey visit.

Do I need planning permission to install air conditioning?

In most cases, residential air conditioning installation does not require planning permission, as outdoor units are typically covered by permitted development rights. However, restrictions may apply in listed buildings or conservation areas. Our team can advise based on your property.

How much does air conditioning installation cost?

Installation costs vary depending on the system type, number of units, property access and any additional electrical work required. Contact Climachill for a no-obligation site survey and quote.

Do you install air conditioning throughout Sussex and Surrey?

Yes. Climachill installs air conditioning across Sussex, Surrey and the wider South East of England. Visit our areas covered page for more detail.

How often should installed air conditioning be serviced?

We recommend annual servicing to maintain efficiency, extend the life of the system and comply with manufacturer warranty requirements. Climachill provides planned maintenance contracts for both domestic and commercial clients.

Is installed air conditioning energy-efficient?

Modern split systems are significantly more energy-efficient than older systems and more efficient than portable units for long-term use. Many systems now carry A+++ energy ratings. Our team can advise on the most efficient options for your budget.

Do you service air conditioning systems you did not install?

Yes. Climachill services, repairs and maintains air conditioning systems regardless of who originally installed them. Contact our team to arrange a visit.

What our customers say

Customer Reviews

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.

Kieran Connolly
Managing Director, Blockbusters Contracts, Glynde

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.
