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
Quwaizah is a residential district of small to medium villas and older apartment buildings on flat ground, with electrical services that may be limited in some older areas, so electro-mechanical planning requires deep understanding of local grid capacity and strong coordination with the electricity authority if capacity upgrades are needed. Building spacing is moderate but long runs may need additional compensation devices, and the high heat and humidity demand materials rated for local conditions.
Quwaizah lies in south Jeddah, a district of villas and older residential buildings on flat ground.
Most buildings here need special load assessment before installation due to local grid constraints.
The AC setup in Quwaizah
- 1
Simple central system with added protection
Buildings here typically use one central system but with advanced protection devices because the grid may be unstable.
- 2
Compensation devices for voltage and load fluctuation
We install voltage regulators and smart protection breakers to prevent power cuts or sudden failures.
- 3
Insulated connections with heavy-gauge cables
For long distances we use heavy-gauge insulated cables to minimise electrical losses and heat generation.
Before the visit
Before our visit in Quwaizah
- 1
Check available electrical grid capacity
Before the visit, contact the electricity authority about capacity available to your property and bring the documentation, so we know how many amps are available.
- 2
Tell us about current wiring and breaker condition
If the building is older, describe the condition of existing wiring and breakers or photograph them so we know if they need replacement.
- 3
Pinpoint the location of pump room and control panel
Tell us exactly where you will place pumps, tanks and controls, and confirm the floor or roof is strong enough.

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.
Power supply in the district is sometimes weak, does that affect the AC electro-mechanical system?
Yes, voltage fluctuations affect pumps and controls. We install voltage stabilisers and surge protection if the grid is unstable, and recommend contacting the electricity authority to check available capacity.
Do we need special protection equipment because of local conditions?
We often install advanced protection breakers and power conditioning devices to protect pumps and controls from sudden faults.
The building is old, will the foundations and floors support pump and tank weight?
We assess foundation strength first, and if needed we arrange solutions like load distribution or roof mounting instead of ground-level placement.
Long runs across the district reduce system efficiency, what do you do?
We install distance-compensation devices like pressure-limiting valves and capacitors, and use larger-gauge cables to reduce voltage drop and heat in the wiring.
