Cooling fit for a mosque
Mosque HVAC in Al Marwah
In Al Marwah, central Jeddah, mosques old and new have varying ceiling heights and depths, requiring cooling that adapts to different architectural forms. Alrabih balances cooling power with silence to ensure undisturbed worship.

- Quiet units

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 Marwah in central Jeddah blends older mosques with moderate ceiling heights and newer ones with architectural domes. This mix demands different designs for each mosque: older buildings may need system upgrades without major alteration, while newer ones allow more flexibility in distribution. Humidity and dust from the busy central streets make regular filter cleaning and indoor air quality care essential.
Al Marwah sits in central Jeddah, a mixed district with both older-established mosques and newer buildings showing architectural variety.
Al Marwah mosques range from simple distributed cooling in older buildings to advanced central systems in newer prayer halls.
The AC setup in Al Marwah
- 1
Simple distribution systems in older mosques
Older Al Marwah mosques typically have simple distribution with split units or small packaged systems placed in corners and recesses.
- 2
Central systems in modern mosques
Modern Al Marwah mosques have robust central AC systems distributing cold air through extensive duct networks and regulated ceiling vents.
- 3
Multi-stage air filters
Mosques in busy central Jeddah benefit from robust multi-stage filters to shield indoor air from street dust and pollution.
Before the visit

Identify available space for equipment and ducts
We inspect roofs, crawl spaces and suspended ceilings in advance to map where new ducts and units can run or old equipment can be replaced.
- 3
Understand budget and priorities
We discuss with mosque management the available budget and priorities, whether focused on performance improvement, energy savings or new maintenance contracts.

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.
Our mosque is old with a moderate ceiling; can you improve the cooling without major rebuilding?
Yes, we assess the existing system and add distribution units or replace older equipment with modern units without requiring major structural changes.
Al Marwah's streets are busy and dust seeps in; how do we keep the air inside clean?
We select high-quality air filters and recommend cleaning them every one or two months depending on dust levels. A good system should have at least two filter stages to trap fine particles.
The mosque shares a building with other facilities; will the cooling system affect neighbouring spaces?
We design systems to be mechanically isolated from other units, and install acoustic barriers to minimise sound and cold air transfer to adjacent spaces.
When should the mosque's central system be inspected and cleaned?
We recommend a full inspection once yearly before summer, air filter cleaning every two months, and duct and coil cleaning at least once yearly to ensure stable operation and high efficiency.
