Cooling fit for a mosque
Mosque HVAC in Al Asaliyah
Mosque HVAC in Al Asaliyah, south Jeddah, requires a system that cools vast prayer halls with high ceilings and handles variable worshipper numbers at each call to prayer. Alrabih designs the air distribution to reach every corner evenly and selects units that run quietly without disturbing 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.

What sets this district apart
Al Asaliyah is a diverse residential district with mosques of varying sizes, from small neighbourhood ones to large mosques with spacious prayer halls and domes. The intense heat and high humidity south of Jeddah place heavy demand on the HVAC systems, particularly during peak hours when sudden worshipper inflow raises the hall temperature quickly. Proper air distribution design and wise selection of outdoor units (usually roof-mounted) are essential to ensure the system runs reliably and quietly.
Al Asaliyah lies in south Jeddah, a residential district with mosques of various sizes among relatively wide streets and accessible roofs for outdoor units.
Mosques here typically rely on central systems or distributed ceiling units, since high ceilings and domes require engineered airflow to reach all zones.
The AC setup in Al Asaliyah
- 1
Central system with one or more condensers
Larger mosques in Al Asaliyah typically use one or more central systems on the roof, with ductwork distributed through the ceilings to all prayer hall zones.
- 2
Multiple distributed ceiling units
Some mosques use multiple ceiling indoor units linked to outdoor condensers, achieving better cooling distribution across the vast prayer hall.
- 3
Concealed air ducts beneath suspended ceilings
Ducts and ductwork are typically hidden beneath suspended ceilings to maintain the mosque's aesthetic and preserve its acoustics.
Before the visit
Before our visit in Al Asaliyah
- 1
Assess the ceilings, domes and open spaces
Before our visit, ensure we can access the ceilings, dome and various prayer hall zones to understand the required engineering design.
- 2
Confirm roof access and planned outdoor unit locations
Confirm our team can safely access the roof and identify preferred outdoor unit locations away from windows.
- 3
Coordinate visit times with the mosque administration
Contact us in advance to schedule the visit outside main prayer times so we do not disrupt worship.

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 handle the changing number of worshippers at each prayer time?
We design the system to handle peak occupancy, with engineered air distribution that achieves even cooling throughout all zones even when the hall fills, and we use thermostats and sensors to balance the load.
Mosque roofs here are exposed to intense heat, does that affect the outdoor units?
Yes, open roofs in south Jeddah increase the cooling load on the outdoor unit, so we choose units sized to the ambient heat and position them on the roof to ensure good airflow around the condenser.
Does the air distribution design reach all parts of the prayer hall and dome?
Yes, we design the ductwork and diffusers so cold air reaches every row and corner, especially under the dome where heat rises, using concealed ducts and strategically placed outlets.
Noise from the AC might disturb the worshippers, how do you prevent that?
We select units with low noise ratings, mount ducts and outdoor units on flexible isolators to reduce vibration and sound, and position outdoor units away from the prayer hall windows.
