Professional Air Conditioning Installation by Cool You
Choosing the right air conditioning system is only part of the process. How it is surveyed, designed and installed is just as important.
Cool You provides a complete air conditioning service, from your first enquiry and property survey through to system design, installation, commissioning and ongoing support.
Whether you need fully internal air conditioning, a conventional system with an external condenser, single-room cooling or a multi-room installation, our team will recommend the most appropriate solution for your property.
Who Will Install Your Air Conditioning?
Cool You uses its own in-house team of F-Gas-certified, DBS-checked engineers to install your air conditioning system.
We do not use subcontractors.
That means the people fitting your system work directly for Cool You, understand the systems we supply and have extensive experience installing air conditioning in apartments, houses, listed buildings and other properties where the work can require a more specialist approach.
Our team manages the installation from start to finish, including system positioning, pipework, testing, commissioning and handover.
This gives you one company responsible for the complete process.

How Does the Air Conditioning Installation Process Work?
Every installation starts with understanding the property and how you want to use the space.
1. Initial Enquiry
We begin by discussing the rooms you want to cool, your property type and any restrictions you already know about.
This helps us understand what's possible before arranging a survey.
2. Property Survey
An experienced Cool You surveyor assesses the property and considers:
- Room sizes
- Cooling requirements
- Glazing and solar gain
- Possible indoor-unit locations
- Condenser location
- Pipe routes
- Water and drainage connections where required
- Electrical supply
- Noise considerations
- Access
- Leasehold, listed-building or other property restrictions
The survey lets us design the installation around your home, rather than trying to make a standard system fit every property.
3. System Design
Once we understand the property, we recommend the most appropriate air conditioning solution.
This may be:
- A fully internal water-cooled system
- A conventional split system with an external condenser
- A single-room installation
- A multi-room system
- Wall-mounted room units
- Concealed or ducted air conditioning
For more information about system options, explore our air conditioning ranges.
4. Detailed Quotation
We provide a clear quotation based on the system, installation requirements and work discussed during the survey.
For more information, see our guide to air conditioning installation costs.
5. Installation Day
For many standard installations, our engineers arrive at around 8:00 AM.
For fully internal systems, the condenser is positioned discreetly inside the property. Depending on the layout, this may be in a utility cupboard, beneath a sink, in a laundry area or another suitable service space.
Pipework is routed through ceiling voids, wall spaces or other concealed routes wherever the property allows.
We then install the indoor units in the rooms being cooled.
6. Testing and Commissioning
Once installation is complete, our engineers test and commission the system.
We check:
- Cooling performance
- Refrigeration system operation
- Drainage
- Controls
- Indoor units
- Condenser operation
- Overall system performance
7. Handover
Before leaving, we explain how to operate the system and answer any questions you may have.
We complete many straightforward installations in one working day, often finishing between 4:00 PM and 5:00 PM.
For larger or more complex installations, we will explain the expected programme before work begins.
Will Air Conditioning Installation Cause Much Disruption?
Cool You installations are designed to minimise disruption to your home.
Our engineers protect work areas, route pipework discreetly wherever possible and clean up after the installation.
For many standard installations, everything is completed within a single working day.
Because we use our own installation team rather than subcontractors, the engineers fitting the system are familiar with Cool You products and the standards we expect in customers' homes.

Where Is the Condenser Installed?
This depends on the type of air conditioning system.
Fully Internal Air Conditioning
With a fully internal, water-cooled system, the condenser is installed inside the property.
Suitable locations can include:
- Utility cupboards
- Kitchen units
- Beneath sinks
- Laundry areas
- Service cupboards
- Other discreet internal spaces
The exact position depends on available space, access, plumbing and the property layout.
For more information, explore our fully internal air conditioning solutions.

Conventional Air Conditioning
Where an external condenser is suitable and permitted, it may be installed outside the property in an appropriate location.
During the survey, we can explain which approach is most suitable.
Fully Internal or External Air Conditioning?
No single system is right for every property.
A conventional system with an outdoor condenser can be an excellent solution where external equipment is permitted. However, many apartments, listed buildings and architecturally sensitive properties cannot accommodate an outside condenser.
In these situations, a fully internal water-cooled system can provide an alternative. Cool You has specialised in fully internal air conditioning for over 15 years and was the first company to bring this type of system to the London market.

Air Conditioning for Different Properties
The right installation depends heavily on the building.
Apartments and Flats
Apartments often have restrictions on external equipment, limited outdoor space and complex pipe routes. Cool You has extensive experience designing discreet systems for these properties.
Residential Properties
From bedrooms and living rooms to home offices and multi-room installations, you can design air conditioning around how you use your home.
Listed Buildings
Listed and architecturally sensitive properties require particular care. Fully internal air conditioning can avoid the conventional external condenser, though you should always consider the relevant permissions for each property.
London Properties
London presents particular installation challenges, including leasehold restrictions, conservation areas, high-rise developments and limited external space. For detailed information about London properties and our work across the capital, visit our dedicated air conditioning in London page.
Single-Room and Multi-Room Air Conditioning Installation
Air conditioning can be installed in one room or designed to cool several areas of a property.
Common applications include:
- Bedrooms
- Living rooms
- Home offices
- Open-plan living areas
- Loft rooms
- Multiple bedrooms
- Whole apartments
Depending on the system, one condenser may serve several indoor units.
During your survey, we calculate each room's cooling requirements and recommend the most appropriate configuration.
Wall-Mounted, Concealed or Ducted Air Conditioning
The indoor unit is one of the most visible parts of an air conditioning installation, so appearance can be important.
Wall-Mounted Units
Wall-mounted units provide efficient cooling and are usually the simplest option to install. Modern units are compact, quiet and available in a range of designs.
Concealed and Ducted Air Conditioning
Where interior appearance matters most, concealed or ducted air conditioning can provide a more discreet solution.
The room unit is hidden within a ceiling void, joinery or another suitable space, with cooled air delivered through discreet grilles. The property needs sufficient space for this type of installation, so we normally assess it during the survey.
