Cooling fit for a mosque
Mosque HVAC in Al Asalah
Mosque cooling in Al Asalah demands a system that distributes cold air evenly across the prayer hall and main chamber, whilst keeping noise low enough not to disturb worship. Alrabih's team sizes the distribution to match the ceiling height, dome geometry and thermal load.

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
North Jeddah's Al Asalah district includes modern mosques with large prayer halls, high ceilings and domes that receive varying numbers of worshippers between daily prayers and Friday services. Central or semi-central cooling is the only effective option to cover these large areas with even distribution, and the ductwork must be designed to avoid direct cold air blasts at the imam or congregation.
Al Asalah in north Jeddah is a district featuring modern mosques with spacious halls, high ceilings and architectural domes.
Most Al Asalah mosques run central AC systems or multiple distributed indoor units across the prayer hall.
The AC setup in Al Asalah
- 1
High-efficiency central AC system
Al Asalah's modern mosques need a large-capacity central chiller with high efficiency to cover the main hall, chambers and facilities with even distribution.
- 2
Concealed ductwork under the ceiling
Ducts run beneath the ceiling or within the plenum above a suspended ceiling, preserving the mosque's aesthetics whilst distributing air quietly.
- 3
Specialised air diffusers at precise angles
Diffusers are chosen to direct cool air away from the imam and congregation seating, whilst covering the entire hall.
Before the visit
Before our visit in Al Asalah
- 1
Obtain the mosque's architectural plans
We need the ceiling, dome and mihrab plans to calculate correct distribution and locate ducts and diffusers before the site visit.
- 2
Coordinate the visit time with the imam or administration
Choose a time outside prayer hours and classes so we can access all parts of the mosque freely.
- 3
Ensure roof and outdoor space access
Confirm that the roof and outdoor area can be safely accessed to install outdoor units and routing routes.

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 cool air evenly across a large prayer hall with a dome?
We survey the ceiling height, dome position and hall dimensions, then install distributed ductwork along the ceiling or side walls to avoid direct drafts on the imam and congregation, whilst ensuring uniform coverage.
Cold air draughts bother worshippers in the front rows, what can we do?
We use air diffusers at precise angles and lower velocities in the front rows, and install dampers in specific ducts to reduce flow where the imam and early worshippers sit.
The prayer hall warms quickly on Fridays when the mosque fills up, does that change the design?
Yes, we size the cooling capacity for peak thermal load on a full Friday congregation, and include a safety margin so comfort is maintained even at maximum occupancy.
Noise from AC units distracts worshippers, how do you manage it?
We select units with low noise ratings, fit acoustic insulation in ducts and around indoor and outdoor units, and run the system at low speeds during prayers.
