Cooling fit for a mosque
Mosque HVAC in Al Majd
Mosque HVAC in Al Majd demands systems covering the wide halls and high domes of the north-east district. Alrabih designs the cold distribution evenly across the prayer rows, keeping operation quiet during 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.

| 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
Mosques in Al Majd sit in a relatively modern residential area with spaced-out buildings and feature high halls with complex ceilings requiring balanced airflow distribution. The tall ceilings and room size mean central AC with concealed ducts is best for covering all prayer rows without intrusive noise. The summer heat and humidity add load as worshippers gather, so robust systems and regular maintenance are essential.
Al Majd lies in north-east Jeddah, a modern residential district with mosques featuring wide halls and raised domes.
Most Al Majd mosques run central AC, with outdoor units mounted on roofs or at building sides due to the available space.
The AC setup in Al Majd
- 1
Central AC with concealed ducts
Wide halls and high domes call for hidden duct networks under ceilings or within walls for even, quiet distribution.
- 2
Outdoor units on roof or building side
Al Majd's spacious roofing allows easy outdoor unit placement, with insulated copper runs rising from the exterior.
- 3
Central control system with load balancing
Larger mosques need smart thermostats and multi-compressor balancing to maintain temperature as worshipper numbers rise.
Before the visit
Before our visit in Al Majd
- 1
Clarify outdoor unit location and roof access
Tell us whether the unit sits on the main roof or building side, and whether it can be safely accessed during servicing.
- 2
Pinpoint indoor duct vents and coil locations
Knowing where coils, filters and ceiling vents sit helps us plan cleaning and servicing ahead of the visit.

Confirm workspace for the team inside the mosque
Coordinate with the mosque imam or maintenance officer to schedule work outside prayer times, and arrange a safe space for equipment.

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 cold air evenly across a large prayer hall?
We design a hidden duct network with multiple distribution points spread across the rows, using ceiling vents positioned to avoid direct air streams on worshippers.
Al Majd mosque roofs are spacious, is there room for larger outdoor units?
Yes, the roof space and open area here offer better options for unit placement and pipe routing without crowding.
Summer heat and prayer hall crowds, how does the AC cope during Ramadan?
We select systems sized above the minimum, with strong compressors and cooling balance built to handle peak load when the hall fills, and pre-Ramadan servicing is essential.
Central AC with high domes, does it need more maintenance than split units?
Yes, longer ducts and complex ceilings collect more dust, so duct and coil cleaning twice yearly maintains distribution and cooling performance.
