Cooling fit for a mosque
Mosque HVAC in Al Jawharah
In Al Jawharah, south Jeddah, most mosques are modern buildings with spacious halls and high domes requiring powerful, even cooling. Alrabih designs cooling systems that cover large areas and maintain quiet during prayer times.

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?

|---|---|---|
| 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
Modern Al Jawharah has contemporary mosques with spacious prayer halls reaching 8 metres or more in height and central domes. This height demands precise distribution of cold air from both high and low points simultaneously to prevent hot air pooling under the domes. Summer humidity and intense heat increase the cooling load, and sudden changes in worshipper numbers require a flexible system.
Al Jawharah in south Jeddah is a modern district with contemporary mosques featuring spacious halls and high domes.
Modern mosques in Al Jawharah typically run central ducted systems with air channels distributed from the ceiling and hall sides.
The AC setup in Al Jawharah
- 1
Central system with ceiling distribution ducts
Most modern mosques in Al Jawharah rely on central cooling units with ducts routed through the ceiling and hall sides.
- 2
Multi-level distribution for high domes
High domes require cold air outlets at different heights to ensure even coverage and prevent hot air pockets.
- 3
Outdoor units on the roof or side yard
In Al Jawharah, outdoor units are typically placed on mosque roofs or side yards due to narrow street access.
Before the visit
Before our visit in Al Jawharah
- 1
Coordinate with the mosque administration and prayer times
Schedule the visit well away from prayer times and consult the mosque administration about any restrictions on entry or noise.
- 2
Identify the outdoor unit location and roof access
Confirm access to the roof or side yard and measure the distance between where the outdoor unit will sit and the prayer hall interior.
- 3
Agree on air outlet direction and sound control
Discuss with the mosque administration where indoor air outlets will be positioned and how to minimise noise and draughts in the hall.

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 cool the high domes in modern mosques?
We position cold air outlets near the high domes and balance them with lower distribution points to prevent hot air accumulating beneath.
The street outside our mosque is narrow, does that affect the outdoor unit placement?
Narrow streets in Al Jawharah require coordination with the mosque administration and municipality to locate the outdoor unit safely, often on the roof or a side yard.
Summer heat and humidity are intense here, can the system handle the load?
Cooling systems for modern mosques must be sized for peak summer load, accounting for coastal humidity and the variable number of worshippers.
Will the air outlets disturb prayer and Quranic recitation?
We select low-velocity air distribution systems with acoustic design, positioning outlets near walls and ceiling to minimise noise and strong draughts in the prayer hall.
