Cooling fit for a mosque
Mosque HVAC in Quba
In Quba, north-east Jeddah, mosques need cooling that handles the coastal heat and humidity while distributing cold air evenly across the large hall and high dome. Alrabih designs the ventilation system to run quietly so it does not disturb 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
Quba is a relatively newer district with architecturally varied mosques, from high domes to flat ceilings, and the long summer combined with coastal humidity puts heavy pressure on any cooling system. The mosques here draw growing numbers of worshippers, especially at the mandatory prayer times and Friday prayers, so the design needs powerful units that can lower the temperature quickly and distribute cold air evenly across every row. Sound control is critical because any noise from the AC units disrupts concentration and reverence during prayer.
Quba lies in north-east Jeddah, a newer residential growth area with modern mosques featuring varied dome and ceiling designs.
Most mosques in Quba require central cooling units or multiple large-capacity systems to effectively cover the wide halls and high domes.
The AC setup in Quba
- 1
Multi-zone central cooling system
Quba's mosques with large halls and high domes benefit from a central system divided into zones, ensuring balanced cold air distribution.
- 2
Air ducts distributed to main halls and prayer areas
Ducts are designed to deliver cold air to the rows and dome area evenly, avoiding direct cold drafts on worshippers.
- 3
Humidity-resistant outdoor heat units
Outdoor units are selected with humidity-resistant materials and coatings to withstand the coastal moisture and air salinity in the north-east.
Before the visit
Before our visit in Quba
- 1
Bring the mosque's plans and measurements
We need the mosque's drawings and measurements of the hall, dome, entrances and windows to design the system accurately.
- 2
Identify outdoor and roof mounting points
Ensure the roof or exterior walls are suitable and safe for mounting outdoor units, with access available for future maintenance.
- 3
Coordinate installation timing with mosque management
Agree with the mosque's imam or manager on installation times that avoid prayer schedules or religious events to minimise disruption.

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 handle high domes and varied ceiling heights in mosques?
We survey the mosque's design and ceiling heights before selecting the distribution system, using positioned air ducts and balancing fans to ensure cold air reaches every area equally, including underneath the dome.
Does the coastal humidity in Quba affect the AC system's durability?
Yes, high humidity stresses the motor and coil components, so we choose corrosion-resistant units and recommend regular maintenance to protect the system from coastal effects.
How many outdoor units will I need and where should they be mounted?
That depends on the mosque's size, building shape and cooling capacity required, which a site visit confirms. Units are typically mounted on the roof or exterior walls away from the entrance and windows.
Can the AC noise level be controlled during prayer times?
We select units with quiet motors and design the distribution system to run efficiently at lower speeds when needed, reducing noise without sacrificing adequate cooling during prayers.
