Cooling fit for a mosque
Mosque HVAC in Al Mahamid
Mosque HVAC in Al Mahamid, East Jeddah, faces a constant challenge: large numbers gather for prayers in intense heat and coastal humidity. Alrabih designs a cooling system that distributes cold air evenly across all rows while maintaining the quiet needed for 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.

What sets this district apart
Al Mahamid is an expanding residential district in East Jeddah, home to a growing number of mosques and Islamic centres in relatively modern buildings with high ceilings. These mosques welcome large congregations at peak times, especially Friday prayers and Taraweeh, and need a robust central system to cool wide spaces without noise that disturbs focus. The coastal humidity and daily temperature swings place extra strain on cooling efficiency year-round.
Al Mahamid lies in East Jeddah, a modern residential district housing mosques with high ceilings and spacious prayer halls.
Most mosques in Al Mahamid have central ducted cooling systems covering the main prayer hall and side corridors together.
The AC setup in Al Mahamid
- 1
Multi-zone central ducting system
The main hall, side corridors and women's section need separate control zones, so we design one system with dampers and ducts allocated to each area.
- 2
Outdoor units on roof or side wall
Most modern Al Mahamid mosques have sturdy roofs that can bear large units, or suitable side walls away from the main entrance.
- 3
Insulated copper pipes to minimise heat loss
Piping runs from the roof to the hall must be carefully insulated to preserve cooling over the distance, especially in extreme heat.
Before the visit
Before our visit in Al Mahamid
- 1
Provide the mosque's floor plan and dimensions
Tell us the main hall's area, ceiling height and side spaces so we can calculate system capacity accurately before the visit.
- 2
Confirm roof and wall access for units
Make sure our team can safely reach the roof or side walls to install the outdoor units and piping.
- 3
Coordinate with the imam or mosque manager
Discuss visit and work times with the mosque's management so they do not clash with prayer times or religious events.

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 wide prayer hall with a high ceiling?
We design a multi-outlet ducting network distributed across ceilings and walls so cold air reaches every prayer row with minimal heat loss, and we select low ventilation speeds to minimize noise.
Can you install outdoor units on the mosque's roof?
Yes, most mosques in Al Mahamid have open roofs suitable for outdoor units, and we verify roof strength and distance from the main hall before installation.
Our summer humidity is very high, can the system handle it?
Yes, Al Mahamid's coastal humidity is high, which is why we select units with strong cooling and dehumidification capacity, and ensure regular maintenance of filters and pipes to prevent moisture build-up.
Sometimes very large crowds gather for major prayers, will the system be enough?
We size the system based on the highest expected congregation during main prayers and Taraweeh, and ensure the system cools the hall even at full capacity.
