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 Khumrah is a mixed district in south Jeddah blending older residential areas with newer developments, its mosques ranging from simple small halls to slightly larger ones in small commercial centres. The building stock is diverse: some older structures with moderate ceilings, others newer and more spacious. This variation means cooling systems cannot be one-size-fits-all; each design must suit that mosque's character and surrounding building, whilst managing intense southern heat and high coastal humidity.
Al Khumrah lies in south Jeddah, a mixed residential area with both older and newer buildings containing mosques of varying size and design.
Al Khumrah mosques use a mix of small split units in older quarters and simple centralised systems in larger mosques within commercial centres.
The AC setup in Al Khumrah
- 1
Small split or enhanced window unit
In small old mosques in narrow quarters, we install one or two split units or an upgraded window unit with high efficiency for simple, effective cooling.
- 2
Simple centralised system in commercial-centre mosques
Larger mosques in small commercial centres get a simple centralised system with one outdoor unit and basic main ducts distributing cooling.
- 3
Reinforced thermal insulation on shared walls
If the mosque adjoins heat-generating shops or storage, we add extra insulation layers to shared walls to reduce heat load.
Before the visit
Before our visit in Al Khumrah
- 1
Assess building character and available space
Before visiting, tell us if the mosque is in an old quarter or commercial centre, and specify available space for the outdoor unit and any structural limits.
- 2
Confirm electrical supply and dedicated circuit
Check if a dedicated circuit is available or can be added for the AC, and inform us of the voltage and existing electrical details.
- 3
Coordinate with superintendent on times and maintenance
Agree with the superintendent on best times for visiting, installation and regular maintenance, away from prayer hours.

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.
Our mosque is small and old in a narrow quarter, can you cool it?
Yes, we install small split units discreetly on exterior walls to fit the limited space and old structure without major changes.
The mosque is in a small commercial centre, how do you handle heat from neighbouring shops?
We add extra thermal insulation to shared walls with shops, and design the system with higher spare capacity to absorb extra heat load.
Southern humidity causes dampness in the hall, how do you solve this?
We install small dehumidifiers or select split units with high-efficiency moisture extraction to remove excess humidity during normal cooling.
Older quarter electricity is weak, can you run a large AC unit?
We assess the existing electrical supply during inspection, and if weak we recommend adding a dedicated AC circuit via a licensed electrician.
