Cooling fit for a mosque
Mosque HVAC in Al Faisaliyah
Mosque HVAC in Al Faisaliyah faces a specific challenge: the prayer hall fills suddenly at each call to prayer, with high ceilings and domes that demand careful design. Alrabih's team sizes the cooling system to distribute cold air evenly across every row whilst keeping sound levels low enough for 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
Al Faisaliyah is a relatively newer district with architecturally varied mosques, some near main roads and others set within residential neighbourhoods. The prayer halls here have high ceilings and may include domes or natural ventilation openings, requiring powerful central cooling systems to distribute air evenly without creating cold draughts across the worshippers' rows. Location and prayer-hall width affect duct layout and distribution, plus coordination with the mosque's management is needed to avoid disruption during prayer times.
Al Faisaliyah lies in central Jeddah, a modern growth area with residential and commercial buildings alongside architecturally designed mosques with high ceilings.
Most Al Faisaliyah mosques rely on central ducted cooling systems to cover the main prayer hall and the side aisles.
The AC setup in Al Faisaliyah
- 1
Central ducted system with distributed channels
Modern mosques in Al Faisaliyah need a strong central system with distribution ducts above the ceiling and within walls to cover the prayer hall and aisles evenly.
- 2
Outdoor unit in the courtyard or on the roof
The outdoor unit is usually placed in the mosque's courtyard or on the roof, with additional sound insulation to avoid noise near the worshippers.
- 3
Strong air filters and regular changing
Air quality in the prayer hall matters, so we install high-efficiency filters and advise regular replacement schedules for maintenance.
Before the visit
Before our visit in Al Faisaliyah
- 1
Obtain the mosque layout and measurements
Before the visit, share a sketch of the main hall, aisles and approximate dimensions so we can size the system accurately.
- 2
Coordinate with the mosque management for access
Make sure the mosque's management knows when the team will visit, and identify the easiest entry points to the prayer hall and the courtyard or roof for the outdoor unit.
- 3
Check the current electrical connections
Identify where the main electrical panel and nearby outlets are, especially near the proposed outdoor unit location, before the visit.

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 high ceilings and domes in the prayer hall?
We design the distribution system so cold air reaches every row in the prayer hall, even beneath the high domes, whilst ensuring there are no uncomfortable cold draughts.
The mosque needs cooling only during certain prayer times, can the system run in part-load mode?
We select units and water pumps with variable efficiency, so the system runs at full capacity during busy prayer times and at reduced power at other times.
Summer heat and humidity in Al Faisaliyah may stress the prayer hall's cooling, is that expected?
Yes, Jeddah summers are very demanding, so we size the cooling capacity above the minimum and advise regular maintenance before the hot season.
Is the mosque's power supply adequate for strong cooling units?
We inspect the existing electrical connections and assess whether they need upgrading before we install the system, and we coordinate this with the mosque's management.
