Cooling fit for a mosque
Mosque HVAC in Al Salihiyah
Mosque cooling in Al Salihiyah, east Jeddah, combines desert heat with coastal humidity, needing a system that balances cold air across the prayer hall and side rooms without disrupting worship. Alrabih designs for high ceilings and domes with precise sound and distribution control.

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 Salihiyah is a medium-density residential district with mosques featuring medium to large halls, sitting between coastal and desert zones so heat and humidity combine. Mosques here often have separate smaller rooms or side chambers, calling for central cooling with separate control zones. Energy efficiency matters in this area because consumption is high, and regular maintenance is vital to protect units from both desert dust and coastal salt.
Al Salihiyah lies in east Jeddah, a medium-density residential zone with contemporary mosques on major roads, where coastal and desert climates meet.
Al Salihiyah mosques typically use central units with zoning because the main hall may need different cooling than the side chambers and women's area.
The AC setup in Al Salihiyah
- 1
Multi-zone central system with thermal separation
The main hall and side chambers need air dampers and separate controls to keep each zone running efficiently.
- 2
Outdoor units with dust-resistant filters
The location between coast and desert means exposure to both desert dust and salt, so high-efficiency filters are essential.
- 3
Load-responsive variable-speed fans
Variable-speed fans save energy during low occupancy and boost output when the hall fills up.
Before the visit
Before our visit in Al Salihiyah
- 1
Confirm the visit time with the imam and staff
We agree on a time that avoids prayer schedules and regular mosque activities.
- 2
Provide measurements of the main hall, side rooms and dome
We need exact dimensions of the main hall, side chambers, women's area and dome to size the system correctly.
- 3
Identify rooftop location and outdoor unit placement
We confirm the rooftop has adequate space for the units with safe clearance from edges and obstructions, and good ventilation around them.

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 manage different cooling zones in a mosque with a main hall and side chambers?
We design one central system with separate control zones, so each area can be adjusted to its own temperature needs and expected occupancy.
Do desert dust and coastal salt reduce the system's efficiency?
Yes, both accumulate on coils and fans, so we select units with high-efficiency filters and recommend seasonal cleaning cycles.
Can energy use be reduced during low-attendance times?
We specify variable-speed fans that ramp down during low attendance and ramp up when the hall is full, cutting energy waste.
Do the outdoor units need a lot of rooftop space?
They need adequate space with safe distance from edges and obstacles, and good airflow around the units to maintain efficiency in high heat.
