Cooling fit for a mosque
Mosque HVAC in Al Mawaddah
Mosque HVAC in Al Mawaddah must distribute cool air evenly across large prayer halls with high ceilings and domes. Alrabih designs systems that keep worshippers comfortable while keeping noise low enough not to disturb prayer.

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
East Jeddah's Al Mawaddah holds several large modern mosques with high ceilings and spacious prayer halls, many built on open ground away from dense residential blocks. This means outdoor units can be placed more flexibly on roofs or in side spaces, but the real challenge is distributing cool air evenly across large halls and under domes without creating strong draughts that disturb worshippers.
Al Mawaddah in East Jeddah is a growing modern district with new mosques built to high architectural standards and spacious prayer halls.
Most modern mosques here run central ducted systems with multiple distribution channels to cover the large halls and domes.
The AC setup in Al Mawaddah
- 1
Central system with multiple distribution ducts
Large halls and high domes require a complex duct network to cover all rows and corners evenly.
- 2
Outdoor units on roofs and side spaces
Open space in Al Mawaddah allows outdoor units to be mounted away from the mosque's main facade to preserve its appearance.
- 3
Advanced thermostats and zone control
Modern systems here include smart thermostats and zone controls to fine-tune cooling by need and save energy.
Before the visit
Before our visit in Al Mawaddah

Map the outdoor unit locations and available roofs
Before the visit, confirm which roofs and side spaces are available and ensure the structure can support outdoor unit weight.
- 2
Coordinate with the mosque management on visit timing
Agree with management on a visit time outside main prayer times, especially Friday.

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 cool air evenly under high domes?
We design a balanced ductwork network that accounts for dome height and hall size, then test air velocity at multiple points to ensure no hot pockets or strong draughts disturb prayer.
Al Mawaddah has open outdoor space, does that ease unit placement?
Yes, the open space lets us place outdoor units on roofs or side areas more easily, reducing the length of pipe and duct runs.
East Jeddah's heat and prayer attendance vary throughout the week, how do you handle that?
We size the system for peak attendance during busy prayer times, then use controllable thermostats to reduce capacity during quieter periods and overnight.
How do you ensure the system runs quietly during prayer without disturbing worshippers?
We select central units and fans with low noise ratings, and line the duct paths with sound insulation to dampen mechanical noise before air enters the hall.
