Cooling fit for a mosque
Mosque HVAC in Tabah
Mosques in Tabah, north Jeddah, need cooling designed for wide halls and high ceilings where heat pools. Alrabih distributes cool air evenly across rows and aisles while keeping sound levels low enough to preserve the calm of worship.

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
Tabah is a relatively modern residential district with mosques dispersed across housing zones, many as standalone buildings with high ceilings and domes needing precise central air distribution. Heat pools under the dome in summer, and coastal humidity increases the cooling load. The design must balance the outer courtyard sometimes with the inner prayer hall without noise that disturbs worshippers or affects the imam's voice.
Tabah lies in north Jeddah, a modern residential zone of low to medium-rise buildings around wide main roads.
Most Tabah mosques need central AC with horizontal ducting under the prayer-hall ceiling, with outdoor units on the roof or side walls.
The AC setup in Tabah
- 1
Central system with horizontal ducts under the ceiling
Most modern Tabah mosques can easily accommodate horizontal ducts under the high ceiling, distributing cool air evenly across rows and aisles.
- 2
High-capacity units to handle coastal humidity
Coastal humidity requires higher-capacity cooling units than inland mosques, with efficient condensate drainage.
- 3
Sound-control solutions to preserve worship
Insulated ducts, carefully directed vents, and low fan speeds to keep the prayer hall quiet.
Before the visit
Before our visit in Tabah
- 1
Confirm safe roof access
Verify that the mosque roof is safe to access and ready for outdoor unit installation before our visit.
- 2
Identify the mihrab and main entrance
Tell us where the mihrab and main entrance are so we can place the outdoor unit and direct airflow away from them.
- 3
Get approval from the imam or manager
Coordinate with the imam or maintenance manager on installation and testing times to avoid clashing with prayer times.

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.
How do you distribute cool air under a very high dome?
We design horizontal distribution ducts under the prayer-hall ceiling with vents spread evenly across the rows, and may add small supplementary fans to push cool air down without noise.
Where do you mount the outdoor unit on a mosque with an open roof?
We usually mount it on the roof in a corner away from the mosque entrance, or on a side wall if available, positioning it away from the prayer-hall windows.
Coastal humidity here is high, does it affect cooling performance?
Yes, humidity increases the cooling load noticeably, so we select units with slightly higher capacity and ensure condensate drains easily from both the prayer hall and courtyard.
Noise from the AC disrupts the imam, how do you handle it?
We choose low-noise fans, insulate the ducts with sound-absorbing material, and locate outdoor units away from the mihrab windows to minimise sound transmission.
