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
Al Khaleej districts contain mid-rise apartment buildings and organised residential complexes, each needing central AC serving multiple flats or units. Electro-mechanical works here require safe, clear wiring from the control panel to pumps, fans and ducts, and coordination with the electrician and mechanical teams on site to prevent errors and faults after handover.
Al Khaleej is a modern residential area in north Jeddah, characterised by mid-rise apartment buildings, organised complexes and clear urban planning.
Most residential complexes here have central AC with unified pump and ductwork systems serving several floors and dozens of flats.
The AC setup in Al Khaleej
- 1
Central system with unified pumps for multiple flats
Residential complexes rely on shared pump units distributing chilled water to all flats via unified ductwork.
- 2
Single control panel for the entire complex
One panel controls temperature and chilled-water flow across all floors and flats on preset schedules.
- 3
Safe wiring from control panel to each unit
Insulated, safe cables link the panel to each pump, fan and temperature sensor to prevent electrical leakage.
Before the visit
Before our visit in Al Khaleej

Confirm site details and available space
Send us a photo of the new control panel location and surrounding space so we can confirm it is suitable for installation.
- 2
Coordinate with contractor and complex management
Give us the site manager's name and complex management number so we can agree on a visit time and suitable work hours.
- 3
Prepare main cables and connections
Verify that main cables from the electrical box have reached near the control panel site before the work day.

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.
Our residential complex needs a new control panel for AC, do you handle that?
Yes, we design and install control panels for central systems in residential complexes. We coordinate electrical wiring with the lead electrician and test it before handover.
How many electrical connections does a central AC system need?
The number depends on the number of pumps, fans, ducts and the complex's size. Send us project details on WhatsApp for an exact figure.
North Jeddah sees rapid construction, how do you ensure wiring quality?
We use approved cables and safe connectors, and test all wiring after installation. We document everything in a technical report before handover.
Do you coordinate with complex management and the contractor about the work schedule?
Yes, we contact the site manager and contractor beforehand to set work times and installation phases that do not disrupt residents.
