Air conditioning systems
Wall mounted system
With stylish indoor units, a wide range of models and controls for each room, wall mounted air to air heat pumps give you comfortable, energy efficient solutions for your living room, bedroom, office etc.
Under ceiling mounted system
These are well-suited to large and long rooms. They provide powerful air flow and are significantly more powerful than standard wall units and can therefore reduce the amount of units needed. This reduces installation costs where multiple units are required.
Floor standing units
The most effective way to air condition a conservatory is by using console units. Conservatories are mostly made of glass and in most instances, the height of the solid wall rarely exceeds one metre. A console unit can conveniently be attached to the wall beneath the glass.
Ceiling cassette system
Efficient and relatively unobtrusive, a ceiling cassette system is an elegant way of providing air conditioning. As the name suggests, these devices are installed on the ceiling, which helps to provide more space on the floor, making them ideal for small rooms. As well as effectively regulating the temperature of the room, their sleek aesthetics can complement the design of the modern office.
Ducted system
A winning trait of a ducted air conditioning system is its ability to almost fully conceal itself from the room, with only the small grilles being noticeable. As well as being able to neatly blend in with the property, they are very effective in cooling large rooms in a very short space of time. This combination of aesthetics and efficiency makes them a favourite for office owners.

Minimising Disruption
Air conditioner installation process
Survey and quote
We visit your property to assess the space and discuss which rooms need cooling. We measure the areas, check electrical supply, and identify the best locations for indoor and outdoor units. You receive a written quote and a drawing that shows where we'll position the units and run the pipework.
Installation
We confirm the installation date with you and order the equipment. Our engineers arrive on the agreed date with all necessary materials and tools. We install the AC units, connect the refrigerant lines and electrical supply, then test the system to ensure it cools properly and operates quietly.
HANDOVER
Our project manager will return to site to make sure the installation is complete and give final instructions of how the temperature control system works.
Our aftercare service team will take over from this point and offer a full service and AC maintenance package to look after the warranty of the air conditioning system and the client's asset(s).

Whether we are retrofitting a new cold room or upgrading a chiller system, we plan our installations meticulously to ensure minimal disruption to your daily operations.
