Cooling fit for a mosque
Mosque HVAC in Al Salamah
Mosque cooling in Al Salamah must distribute air across large halls with very high ceilings whilst keeping noise levels strictly controlled for worship. We design central systems to cover spacious prayer halls and domes while maintaining complete quiet during prayers.
- Even distribution
- Quiet units
- Scheduled servicing

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 Salamah is a modern residential district west of Jeddah with contemporary mosques featuring high ceilings, domes and advanced architecture, requiring powerful central cooling systems that distribute cold air evenly across all rows without creating strong draughts or noise. Jeddah's coastal heat and humidity place constant demand on the system, particularly during crowded prayer times.
Al Salamah lies west of Jeddah and houses modern residential buildings alongside mosques with advanced architectural designs and high ceilings.
Most Al Salamah mosques have architecturally designed ceilings and prayer niches, requiring complex ductwork and precise air velocity control.
The AC setup in Al Salamah
- 1
Central system with distributed ducts across large prayer halls
Modern Al Salamah mosques require one or more central units with ducts running beneath ceilings or inside walls to cover the entire prayer hall.
- 2
Multiple diffusers at low air velocities
Multiple strategically placed diffusers at low speeds ensure worshippers are comfortable and not disturbed by strong draughts.
- 3
Outdoor units sited away from the main entrance facade
Condensers are placed in rear or side areas away from the mosque entrance, to preserve the architectural appearance.
Before the visit
Before our visit in Al Salamah
- 1
Confirm access to the mosque and rear areas
Arrange with the imam or supervisor on a convenient time for the team to enter, and confirm the rear areas and roof are safe and accessible.
- 2
Identify proposed sites for the outdoor units
Ask the mosque supervisor to point out available side and rear areas for the condensers, away from worshippers' sight.
- 3
Check electrical supply and grounding
Confirm separate electrical circuits with adequate capacity for the central fan units and condensers are available, and verify safe grounding for all units.

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 the high ceilings and domes in the mosque?
We design the ducts to distribute cold air from above at calculated angles, reaching the prayer rows without cold air stagnating under the dome. We use multiple diffusers and powerful fans to ensure even distribution.
Can the outdoor units be placed without spoiling the mosque's architectural facade?
Yes, we choose placement carefully, usually in rear or side areas out of sight from the main facade, and we coordinate with the imam or mosque supervisor before the visit.
Jeddah is very hot and humid, how often does the mosque cooling system need servicing?
Coastal humidity and heavy use during prayers mean regular maintenance is needed every two to three months at minimum, with particular focus on ducts, filters and evaporators.
Will the central AC system be completely silent during prayer?
We select fans, ducts and diffuser designs to minimise mechanical and air noise, but cannot promise complete silence. We balance effective cooling with quiet operation as far as the design allows.
