What is trunking for air conditioning piping?
Trunking is a PVC or plastic casing that encloses the copper refrigerant lines and electrical wiring running between an air conditioning indoor and outdoor unit.
In air conditioning installations, trunking refers to the protective plastic or PVC casing that wraps around the copper piping and electrical wiring connecting the indoor evaporator unit to the outdoor condenser. This piping carries refrigerant between the units and must be routed through walls, along ceilings, or down the exterior of buildings in Tampines residential and commercial properties.
Trunking serves two main functions. First, it shields the copper pipes and wiring from physical damage, dirt accumulation, and UV degradation, which extends the system's working life and prevents leaks or electrical faults. Second, it improves the appearance of installations by hiding raw pipework, which matters for both interior finish and street-facing facades where exposed lines would look unfinished.
Trunking comes in various profiles and colours to blend with different wall finishes. It can be bent and routed around corners and along structural features. Most systems use white or neutral tones for indoor runs, though outdoor or exposed sections may use darker materials. Proper sizing and sealing of trunking is important to prevent condensation, pests, or water ingress into the pipe cavity. When selecting aircon installation providers in Tampines, ensuring they use quality trunking material and proper installation technique is part of a durable and neat system setup.
