Air Con Trunking

Air Conditioning Installation

Trunking is an essential aspect of air conditioning installation and repair, protecting your piping, wiring and cables and keeping them out of sight. Trunking also helps weather-proof your installations and ensure they don't suffer accidental damage.  For a recent installation in Hampshire we used black trunking and ducting to complement the client’s modern exterior.

This residential installation included a multi split system comprising of Daikin Stylish interior wall mounted units. The Stylish stands out as one of the most space-efficient designs available, with dimensions measuring just 189 mm. Its elegant aesthetic and the availability of four different colours make it exceptionally adaptable to any room. For their interior spaces, our client opted for the timeless white finish. In contrast, the exterior demanded a more eye-catching touch, featuring a striking black finish for trunking and ducting to the Daikin RXA-A/B units, discreetly positioned on the flat roof - effectively eliminating ground-level clutter.

Is air con trunking necessary?

The necessity of air con trunking depends on the specific requirements and circumstances of your air conditioning system. Aircon trunking is typically used to protect and conceal the refrigerant pipes, electrical wiring, and drainage pipes associated with air conditioning units.

Air con trunking: Installation considerations

  • Aesthetic Considerations: Trunking can help create a neater and more polished appearance for your air conditioning installation by concealing and organizing the various components.

  • Safety and Protection: Trunking can protect the pipes and wiring from physical damage, which can be important, especially in high-traffic areas or if the air conditioning system is exposed to potential risks.

  • Compliance: In some building codes and regulations, there may be requirements for how air conditioning components should be installed and protected. Trunking may be necessary to meet these standards.

  • Accessibility: Trunking can make it easier to access and maintain the air conditioning system. If repairs or maintenance are needed, having components neatly organized in trunking can save time and effort.

  • Climate: In areas with extreme weather conditions or exposure to the elements, trunking can provide an added layer of protection for the components, ensuring the system's reliability.

What is the difference between trunking and ducting?

Trunking and ducting are both terms used in the context of managing and concealing various types of services, such as cables, pipes, or conduits in buildings. While they serve similar purposes, there are key differences between the two:


Trunking: Trunking is primarily used for organizing and protecting electrical cables on the exterior or interior of a building. It often consists of rectangular or square-sectioned enclosures with removable covers. Ducting: Ducting, on the other hand, is used to enclose and manage larger conduits, pipes, or tubes, which can carry various materials, such as air, ventilation, heating, cooling, or fluids (e.g., plumbing pipes, HVAC ducts, or ventilation ducts).


Trunking: Trunking typically has a box-like or rectangular shape with removable lids or covers. It is designed to be easily accessible for cable installation and maintenance. Ducting: Ducting is typically cylindrical or rectangular in shape, depending on its purpose. It is often more rigid and less accessible than trunking because it is designed to contain larger pipes or conduits.


Trunking: Trunking usually contains electrical and data cables, as well as smaller communication and control lines.

Ducting: Ducting may contain larger pipes and conduits that carry substances such as air (for HVAC systems), water (for plumbing), or other utilities.


Trunking: Trunking is designed for easier access and maintenance, with removable covers for easy installation and alterations.

Ducting: Ducting is often less accessible and may require more effort for maintenance, as it is meant to enclose larger and more permanent installations.

Trunking is primarily for smaller cables and is more accessible, while ducting is used for larger pipes and conduits, which may contain materials like air, water, or other utilities, and is typically less accessible.
