Who needs a complete central system?
- 1
A new villa before finishing
The finishing stage is the right time to run central AC ducts before the ceilings close. Delaying the decision means extra cost later or compromises in the duct route that weaken airflow in certain rooms.
- 2
A commercial or office building
A commercial building needs airflow that fits how the floors are divided and how the load varies between levels. The site survey sets unit count, duct routes and outlet positions before any decision is made.
- 3
An old system draining power
Old units, deteriorating ducts and leaking copper push the electricity bill up without cooling the space properly. Replacing the whole system starts with a fresh load calculation, not with larger units pushed into the same old ductwork.
Who it's for
Building a villa and need ducts before ceilings close
We visit during the finishing stage, design duct routes and outlet positions, fabricate the ducts in our workshop and install them before the ceilings close, so you take over a fully working villa.
Ask on WhatsAppManaging a commercial building and replacing an old system
We recalculate the loads, design airflow to match the current floor layout and replace both units and ductwork completely so the system runs reliably without repeated faults.

How we work
How we work
- 1
Survey and load calculation
The engineer visits, measures each zone, and calculates the thermal load per area, accounting for facade orientation, ceiling height and how the space will be used in Jeddah's hot and humid conditions.
- 2
Design and unit selection
We draw duct routes and outlet positions and select units from Carrier, YORK, General, Midea, Gree or Smart Gold, then present the design to you before any work begins.
- 3
Fabrication and installation
Round and rectangular ducts are fabricated in our workshop from G90 galvanised sheet to SMACNA standards, then installed on site alongside the copper runs, insulation and electrical connections.
- 4
Commissioning and handover
We pressure-test the copper lines, vacuum them, check air balance at every outlet and condensate drain fall, then hand the system over to you in full working order.

What sets this district apart
Al Fayhaa is a central area with villas of varying sizes and modern residential blocks at reasonable density, with good spacing to site outdoor units without crowding. Variety in building ages and sizes means different heat needs, so we need precise on-site checks to calculate loads and runs before starting.
Al Fayhaa sits in central Jeddah, an area of varied villas and modern residential blocks with good spacing between buildings.
Most Al Fayhaa villas and blocks need medium-size central systems, with outdoor units typically sited on secure roofs or side spaces with dedicated electrical runs per unit.
The AC setup in Al Fayhaa
- 1
Central system with concealed air-handler unit
Al Fayhaa villas and blocks provide architectural voids and suspended ceilings where the air handler sits efficiently and invisibly.
- 2
Ducts distributed through architectural voids
Distribution runs through voids between ceilings and slabs with full insulation and protection from dust and moisture.
- 3
Outdoor condenser on a safe roof
The outdoor condenser sits on a strong roof with a solid concrete pad and dedicated electrical run rated for the full system load.
Before the visit
Before our visit in Al Fayhaa
- 1
Inspect the roof or side space for the unit
Check roof condition and structural strength, or confirm the side space is safe if that is the alternative, and tell us of any obstacles or environmental factors.
- 2
Identify main rooms and daily usage patterns
Tell us which rooms need intensive cooling and which are secondary, your daily usage patterns, so we design air distribution matching your needs.
- 3
Agree on thermostat and control panel location
Choose the best spot for the main control panel, centrally located and easy to reach, away from direct sun and doorways.

FAQ
Questions about Central AC installation
How do you decide the right unit size for my villa?
We calculate the thermal load for each zone based on its area, ceiling height, number of external openings, orientation and how it will be used. In Jeddah the sun's effect on west-facing facades is significant, and high humidity goes into the calculation. We choose the unit size after this calculation, not before.
Do you make the ducts yourselves or buy them ready-made?
We fabricate round and rectangular ducts in our own workshop from G90 galvanised sheet or aluminium sheet depending on what the project needs. This lets us cut ducts to the exact site dimensions and fit them tightly, avoiding ill-fitting sections that leak air and raise electricity consumption.
What if the copper run to an outdoor unit is very long?
We use Mueller copper in runs of up to 30 metres without welded joints, which reduces potential leak points. If a run exceeds that, the survey determines whether the outdoor unit position needs rethinking or whether the refrigerant charge needs adjustment according to the type shown on the unit's nameplate.
Can each floor of the villa run on its own?
Yes, and it is settled at the design stage. Each floor can have its own unit, or the network can be split into zones with dampers and a thermostat in each, so you do not cool the whole upper floor while the family sits in the majlis. We recommend the right option after the load calculation.
Do the outdoor units need a special base on the roof?
Yes, and the roof surface determines what kind of base is needed. For villas we fabricate a raised steel frame that keeps the unit clear of pooled rainwater and allows airflow beneath it. The exact height and angle depend on the roof pitch and the condensate drain position, which the site survey establishes. The aim is to keep the unit level and to prevent vibration movement during operation.
My villa is medium-sized, how many central units does it need?
Depending on villa size, interior layout and insulation, one central unit may suffice or you might need two for upper and lower floors, our calculation determines that precisely.
Side gaps between villas are sometimes tight, how do you place outdoor units?
We choose the best site for clearance and safe distance from windows and gardens, and if side gaps are too tight we relocate the unit to a safe alternative or propose a different arrangement.
Heat and humidity in Al Fayhaa, are they different from other Jeddah areas?
Al Fayhaa is moderate for solar exposure and seasonal humidity, but we always factor in villa orientation and window positions to ensure a system matching actual conditions.
Some roofs here are older, will they bear the outdoor unit weight?
We inspect the roof first and confirm it can bear the load, and if it is weak we recommend strengthening it or choose a safe alternative side location.
