Air Conditioning Installation in London
Supply and installation of home and office air conditioning — properly sized, cleanly fitted and ready for summer.
Keep your home or office comfortable all year round with a properly sized, cleanly installed air conditioning system. We supply and fit wall-mounted split systems and multi-room setups across London — sized correctly for the space so you get efficient cooling without wasted energy.
The right size for your room
An air conditioner that is too small will run flat out and still struggle on the hottest days; one that is too big cycles on and off, costs more to run and controls humidity poorly. That is why sizing matters. Use the BTU calculator below to get a quick estimate for your room, then we will confirm the exact specification on a site visit before we quote.
A clean, professional installation
A split system has an indoor unit mounted on the wall and an outdoor condenser. We handle the whole job — mounting both units, running the refrigerant pipework and cabling, sorting the condensate drainage and making the electrical connection — then test and commission the system and show you how to use it.
Cooling one room or several? A multi-split system runs multiple indoor units from a single outdoor condenser, so each room can be controlled independently.
Comfort you can rely on
From a single bedroom or home office to a whole-house or office installation, we take care of the sizing, the fitting and the finish so you can enjoy cool, comfortable air the moment it is switched on.

Air Conditioning — FAQs
How do I know what size air conditioner I need?
The right size depends on your room's dimensions, ceiling height, how much sun it gets and how many people use it. Use our BTU calculator on this page for a quick estimate, then we will confirm the exact size on a site visit before quoting.
What is a BTU and why does it matter?
BTU (British Thermal Units) measures cooling capacity. An undersized unit will run constantly and never quite cool the room, while an oversized one wastes energy and cycles on and off. Getting the size right keeps you comfortable and running costs low.
Do you install both the indoor and outdoor units?
Yes. A standard split system has an indoor unit on the wall and an outdoor condenser. We mount both, run the pipework and cabling between them, sort the condensate drainage and make the electrical connection.
Can you cool more than one room?
Yes. A multi-split system runs several indoor units from one outdoor condenser, so you can cool multiple rooms independently. We will size and plan the layout as part of your quote.
Do you service and maintain air conditioning too?
We can install and maintain your system. Regular filter cleaning and checks keep it efficient and extend its life — ask us about a maintenance visit.
Where does the outdoor condenser unit go?
The outdoor unit sits on an external wall, a balcony or at ground level, positioned to keep the pipe runs short and any noise away from living space. In a flat or managed block you may need the freeholder's or managing agent's permission for its location, and we will help you plan a tidy, agreed position.
