When these works are needed
- 1
A new central HVAC project
In commercial, government and industrial buildings, fitting units and ducts is not enough. You need electrical runs sized for the loads, a control panel that starts and stops equipment in the right order, and pumps and pipework designed for the building.
- 2
Extending an existing HVAC system
Adding units or new control zones means extra load on the panel and new control cabling. We review the available capacity on site and define what the extension needs before any work starts.
- 3
Electrical faults stopping the equipment
A unit that will not start despite being in good order, a pump that burns out repeatedly, breakers tripping for no clear reason: these are usually a wiring or panel problem, not a fault in the equipment, and need diagnosis from a technician who understands both sides.
Who it's for
Building a new commercial or government project
We review drawings with the main contractor and take on power panels, electrical runs, control automation, pumps and ventilation from start to handover.
Ask on WhatsAppYour HVAC equipment keeps breaking down
We diagnose the electrical and mechanical side of the system and identify whether the fault is in the panel, the wiring or the control circuits before any work begins.

How we work
How we work
- 1
Review project drawings
We go through the electrical and mechanical drawings with the designer or main contractor and define the power requirements and cable routes before any materials are prepared.
- 2
Site coordination
Electro-mechanical works cross paths with civil works and finishes. We follow the site programme and agree the sequence with other contractors so no trade is held up by a clash.
- 3
Run cables and fit equipment
We pull cables, mount panels, pumps and ventilation fans, then wire the control and automation circuits according to the approved site drawings.
- 4
Coordinated testing and start-up
We test each circuit individually then run the full system together with the AC equipment, checking that automation starts and stops everything in the right order before handover.
Planned coordination or clashes that delay the project?
| Alrabih | The usual way | |
|---|---|---|
| Electrical panel | Sized for the actual load | Rough sizing causes problems later |
| Control wiring | Documented to drawings | Run without documentation |
| Site coordination | Followed with every trade | Each trade works in isolation |
| Start-up test | Full test before handover | Faults found after handover |
| Change documentation | Recorded at handover | Verbal changes, no record |

What sets this district apart
North districts like Al Nur contain modern villas and apartment blocks with spacious layouts requiring central AC systems and heat pumps distributed across multiple rooms and floors. Electro-mechanical work here includes long copper runs from the outdoor unit, separate control panels, control wiring secured in metal conduit, and close coordination with the main contractor, plumbing and the building's primary electrical supply is essential.
Al Nur sits in north Jeddah, a modern residential development with dispersed villas, new apartment blocks and wide-open building plots.
Most projects here require a dedicated control panel with a separate electrical breaker, and copper runs extending 50 metres or more from the outdoor unit.
The AC setup in Al Nur
- 1
Central control system with separate panel
Modern villas and apartment blocks need a dedicated electrical control panel that collects all indoor and outdoor units and manages their operation together.
- 2
Long copper runs secured in metal conduit
The wide distances between indoor and outdoor units call for extended copper runs, placed inside metal conduit secured safely to walls or false ceilings.
- 3
Individual control wiring per indoor unit
Each indoor unit needs its own control wiring, requiring careful routing from the main panel to every room or zone.
Before the visit
Before our visit in Al Nur
- 1
Confirm the main electrical panel's location
Let us know where the villa's main electrical panel sits so we can plan the separate breaker for the system.
- 2
Determine the control panel's mounting point
Choose a dry, accessible spot for the control panel, such as the home's entry or a plant room, away from water and damp.
- 3
Coordinate pipe and wiring routes with other trades
Check with the main contractor, electrical and plumbing teams about existing pipe and wire routes to avoid clashing with our copper runs and control wiring.

FAQ
Questions about Electro-mechanical works
Can you handle the electro-mechanical works when there is already another civil contractor on site?
Yes. We work as a specialist subcontractor alongside the main contractor, coordinating cable routes, pipework and equipment positions with the other trades on site. Before work begins, we identify where our scope crosses the civil and structural work and agree on the sequence of installation to avoid clashes.
What is the difference between the power circuit and the control circuit in an HVAC project?
The power circuit carries current from the panel to the compressor, motor or fan; cable size is set by the load. The control circuit carries low-voltage signals between sensors, thermostats and the controller; it issues run, stop and modulation commands. A fault in either circuit disables the whole system, so each is routed and terminated independently.
Does your work include connecting the automation system to a building management network?
Yes, when a building management network is already present on site. We connect the HVAC control units to the designated interface points and test signal exchange between the two sides. Protocol details and configuration are agreed with the team responsible for the building management network before installation begins.
How do you handle a clash between cable routes and ducts or pipework?
We identify clashes at the planning stage before installation starts, then consult the relevant trades to agree on an alternative route. If a site resolution is not possible, the clash is escalated to the project supervisor for a decision. Priority is always given to keeping the correct bending radius for cables and the required fall on condensate drain pipes, as compromising either affects system performance.
How do you handle a clash between cable routes and ducts or pipework?
Clashes between cable routes, ducts and pipework are common on medium and large projects. We identify them during the drawing review stage, before any trenching or pulling begins, and agree an alternative route with the trades involved. Changing a route on paper is far simpler than reworking it on site.
Do Al Nur's villas need extensive control wiring, how do you manage it?
Yes, multi-storey villas need separate control wiring for each indoor unit. We run them through secured metal conduit fixed to interior walls or concealed in false ceilings before final finishes.
How far do the copper lines run from the outdoor unit in villas like these?
The distance varies with the outdoor unit's location and the number of indoor units, but in modern villas it can extend 50 metres or more, which affects the size of the control panel and electrical breaker needed.
Do you coordinate with the main contractor during installation?
Yes, coordination with the main contractor, electrical and plumbing works is essential to run the control wiring and copper lines without clashing with other pipes or circuits.
Does the control panel need a specific location or space in the villa?
Yes, the control panel needs a dry, accessible location, usually at the home's entry or in a dedicated plant room, away from moisture and water exposure.
