When a mosque needs a specialist approach
- 1
Heat reaching the back rows
Cold air pools near the units and never reaches the back of the hall. In Jeddah's humidity, worshippers in the far rows feel the heat even with the system running. That is a design problem, not a unit fault.
- 2
Noise that disturbs prayer
Unit noise in a quiet hall distracts worshippers and breaks concentration. The right unit type, its position and the air velocity setting all reduce noise to the lowest possible level, and those choices are made at the survey.
- 3
A dome or high ceiling that traps heat
Hot air rises and collects under the dome, so the breathing level stays warm even with large units running. We set diffuser angles and air paths at the survey to push that hot layer out rather than cool over the top of it.
Who it's for
Building a new mosque that needs AC from the start
We join the design stage to fix duct routes and unit positions before ceilings are closed, so the installation is clean and efficient with no remedial work needed later.
Ask on WhatsAppYour existing mosque cools unevenly across the rows
We survey the existing system, find the cause of uneven distribution and propose changes to the airflow paths or units without disrupting the mosque.

What the work covers
- Hall survey and airflow mapping
- Ductwork to SMACNA standard
- Units fitted at surveyed positions
- Airflow check across the rows
- Contracts scheduled between prayers
How we work
How we work
- 1
Mosque survey
We visit the mosque outside prayer times to measure the hall, ceiling height and dome, and agree diffuser positions, duct routes and unit locations before any work begins.
- 2
Design and fabrication
We design the system from the survey data and fabricate the ducts in our own workshop from G90 galvanised sheet, then prepare them for installation.
- 3
Installation at agreed times
We coordinate with mosque management to work between prayers or at times that do not interrupt activities, and we leave the hall clean at the end of each working day.
- 4
Testing and handover
We run the system and measure air distribution at the front and back rows and sound levels, adjusting the balance until comfort is even across the whole hall.
Designed for a mosque or units placed at random?
| Alrabih | The usual way | |
|---|---|---|
| Air distribution | Even across every row | Cold front, hot back |
| Sound | Assessed at survey | Not considered |
| Dome and high ceiling | Planned airflow paths | Hot layer left above |
| Maintenance | Scheduled between prayers | Visits that disrupt use |
| Startup scheduling | Programmed before each prayer | Manual, inconsistent start |

What sets this district apart
Prince Abdulmajeed is an advanced modern residential area with contemporary-style mosques featuring large halls and very high domes. Central ducted systems suit this setting by delivering even cold-air distribution and minimising temperature variation. Coastal proximity, intense summer heat and persistent humidity make regular system maintenance mandatory to prevent mould and dust accumulation and ensure stable performance year-round.
Prince Abdulmajeed sits in south Jeddah, an advanced residential area with modern mosques boasting large halls and very high domes.
Most mosques here require high-capacity cooling units, with outdoor units mounted on reinforced roofs or purpose-built rear courtyards.
The AC setup in Prince Abdulmajeed
- 1
High-capacity central system with extensive ducts
Prince Abdulmajeed's large halls need powerful outdoor units and extensive ductwork ensuring even cold-air distribution beneath tall domes.
- 2
Outdoor units on reinforced roofs or rear courtyards
High-capacity heavy units are mounted on engineered roofs or purpose-built rear courtyards designed to withstand their weight, heat and humidity exposure.
- 3
Smart control systems with live monitoring
A modern control system continuously monitors performance and sends instant alerts if faults or performance dips occur.
Before the visit
Before our visit in Prince Abdulmajeed
- 1
Provide complete engineering drawings
Send comprehensive engineering drawings of the main hall with all dimensions, dome height and locations of exits, entrances and mechanical spaces.
- 2
Confirm structural capacity for the outdoor unit
Verify the roof or rear courtyard can bear a heavy outdoor unit, and notify us of any structural limits or conflicts with other building parts.
- 3
Identify available electrical power and backup generator
Clarify the main electrical panel and any standby generator location and capacity, so we can design safe runs to operate the system reliably.

FAQ
Questions about Mosque HVAC
How do you make sure the far rows get enough cooling?
At the survey we set diffuser angles, air velocity and duct routing so cold air travels to the last row. After installation we measure the temperature difference between the front and back rows and adjust each diffuser's balance until that difference is as small as the space allows.
Can you work in a functioning mosque without disrupting prayers?
Yes. We agree a phased schedule with mosque management in advance and divide the work into sessions between prayers. Before each call to prayer we lift tools, cover any temporary openings and return the hall to a usable state, then resume afterwards.
What type of ductwork do you use in prayer halls?
We fabricate ducts in our own workshop from G90 galvanised sheet, round or rectangular as the design requires. We use Armaflex and Kimmco insulation and Foster sealants to limit heat gain and keep sound transmission through the ductwork as low as possible.
Can the system be set to start just before each prayer time?
Yes. The controls on Carrier, YORK, General, Midea, Gree and Smart Gold units support scheduled start and stop times. At the survey we confirm the scheduling options for the chosen units and programme the timings at handover, so the hall is already cool when worshippers arrive.
Can we cool only part of the hall when fewer people attend?
Yes, if the system is designed in zones. We divide the hall into sections, each with its own unit or closable outlets, so you run the front rows alone when few people attend and the whole hall for Friday prayer and occasions, cutting power use without affecting worshippers.
Our domes are very tall, how do you ensure cooling reaches everywhere?
We calculate total hall volume and dome height, then specify sufficient outdoor capacity and design a balanced duct network delivering cold air from multiple ceiling and wall outlets.
Does coastal humidity affect cooling efficiency and maintenance needs?
Yes, high humidity increases maintenance needs. We recommend monthly inspections of the coil, filter and drain pan, plus regular drain cleaning to prevent mould and blockage.
Does the cooling system need a large mechanical space underground or on roof?
It depends on unit capacity. We visit to measure available space on roof or underground before selecting the outdoor unit size and designing ductwork.
How do you handle electrical runs from the standby generator to the system?
We coordinate with facilities staff on the generator's location and capacity, then design safe electrical runs from the generator panel to the system control board to full safety standards.
