Cooling fit for a mosque
Mosque HVAC in Al Wisami
In Al Wisami, north-east Jeddah, modern mosques need powerful cooling for high ceilings and domes, and the cold air must reach every row evenly without disturbing worshippers. Alrabih's team designs the system to run quietly and distribute cooling efficiently across the large hall.

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
North-east Al Wisami holds modern mosques with high ceilings and domes, often set in clean commercial centres or residential compounds. These mosques need an advanced system controlling temperature and humidity, delivering cold air through ceiling vents without noise that disturbs prayer. The high ceilings and domes demand precise calculations of cooling capacity and central ducting spread across a wide network.
Al Wisami sits in north-east Jeddah, a modern district with architecturally sophisticated mosques featuring high ceilings and domes.
Most Al Wisami mosques run central AC systems distributed through ceiling vents, because of the large halls and high ceilings.
The AC setup in Al Wisami
- 1
Central system distributed through domes and ceilings
Modern Al Wisami mosques with high ceilings and architectural domes call for a robust central distribution that delivers cold air to every area uninterrupted.
- 2
Outdoor cooling units on building roofs
Outdoor units are typically mounted on the commercial centre or mosque roof, with separate air ducts and water drains to keep the prayer hall clean.
- 3
Smart control systems for temperature management
We equip the mosque with advanced thermostats allowing temperature adjustment across peak prayer times and quieter periods, with automatic performance monitoring.
Before the visit
Before our visit in Al Wisami
- 1
Consult with mosque and centre management
We coordinate with the mosque imam and centre management on our visit and work schedule to avoid clashing with prayer times and centre hours.
- 2
Identify roof and duct access routes
We check in advance how safely we can reach the roof, what service ducts and ceiling spaces are available, and where new runs can be threaded.
- 3
Confirm adequate electrical supply
Central cooling units need substantial dedicated power. We check the centre or mosque's electrical distribution board in advance to confirm enough capacity is available before installation.

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 in a mosque with a high ceiling and dome?
We design the central ducting network with vents strategically placed in ceilings and domes so that cooling reaches all rows and corners equally, with no hot or cold spots.
Mosques in Al Wisami are often within commercial centres; are there installation constraints?
Yes, mosques embedded in commercial complexes need coordination with the centre management. We assess available ceiling and service-floor space, and integrate our units with the building's infrastructure without affecting other tenants.
Temperatures in Al Wisami get very high in summer, and prayer attendance peaks at certain times; can the system handle this surge?
We size the cooling capacity based on expected worshipper numbers and peak summer heat. The central system allows fan speed adjustment across distribution zones to match demand throughout the day.
Will the central AC system in the mosque create noise that disturbs prayer and sermons?
No, we select fans and units with very low noise ratings, and install sound dampers in the distribution vents to minimise any hum or flutter during operation.
