Cooling fit for a mosque
Mosque HVAC in Al Falah
In Al Falah, east Jeddah, modern mosques with high ceilings and spacious domes need balanced cooling that reaches every corner. Alrabih's team designs precisely calculated duct networks to distribute cold air evenly and minimise noise 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.
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 Falah is a developed residential area with several modern mosques featuring wide halls, high domes and tall minarets, drawing large congregations especially at the five daily prayers and Taraweeh. The weather is hot and dry in summer with moderate humidity due to slight distance from the coast, but the system must handle temperatures reaching 48°C and distribute cold air efficiently to thousands without acoustic disturbance.
Al Falah sits in east Jeddah, a modern residential zone with contemporary mosques featuring modern architecture and spacious prayer halls.
Most modern mosques in Al Falah come equipped with high-efficiency central cooling systems with distributed ducts and a separate plant room.
The AC setup in Al Falah
- 1
Central system with dedicated chiller
Modern Falah mosques rely on a dedicated chiller that distributes cold air through an extended duct network to all parts of the main hall.
- 2
Separate plant room with independent equipment
The plant room houses the chiller unit, condenser, pumps, and automated temperature and humidity control systems.
- 3
Auxiliary units for entrance and minaret areas
The main entrance and minaret areas may need auxiliary distributed units to maintain comfortable temperatures in waiting areas and corridors.

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 avoid cooling noise inside the prayer hall?
We select low-noise chiller units and design ducts with larger diameters to reduce airflow velocity and the noise it creates.
Can the cooling handle sudden crowding during the five daily prayers?
Yes, we size capacity for peak expected congregation, with extra reserve to ensure effective cooling even when the mosque fills completely.
Al Falah's humidity is moderate, but does it affect system efficiency?
Moderate humidity is less demanding than coastal areas, but we select high-efficiency condensers and design drainage and ventilation carefully to maintain peak performance.
Do very high ceilings require extra ducts?
Yes, ceilings over 8 metres need carefully positioned vertical ducts and extra distribution outlets at height to prevent hot air stagnation.
