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.

- 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.

| 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
Abu Jaalah is a relatively modern residential area of mid-rise apartment blocks with mosques distributed across different neighbourhoods. Buildings are newer than Al Balad and Al Sabeel, with more available outdoor space on roofs and corners, though interior heat is slightly lower than the coast. Mosques here vary from small to large prayer halls, requiring flexible cooling-system choice.
Abu Jaalah is a modern residential district in south Jeddah with mid-rise blocks and scattered green spaces.
Abu Jaalah's mosques vary widely in size, needing flexible cooling systems suited to small, medium and large prayer halls, with outdoor units spread across available roofspace.
The AC setup in Abu Jaalah
- 1
Single or multi-head split unit
Most small to medium Abu Jaalah mosques benefit from a single split or multi-head split from one outdoor compressor.
- 2
Central system for larger mosques
Larger Abu Jaalah mosques may need central ducting with distributed cold-air flow and high capacity covering all prayer-hall sections.
- 3
Outdoor units on separate roofs
Larger mosques may deploy two medium units on different roofs to distribute the load and reduce noise.
Before the visit

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 relatively small in a residential block, what is the best solution?
A single split or multi-head split usually suffices for small and medium halls in Abu Jaalah, with the outdoor unit placed on the roof or rear corner.
Heat here is lower than the coast, how do you size the cooling?
We study average temperatures in Abu Jaalah and expected prayer-hall occupancy, then select moderate capacity with a small safety margin for exceptionally hot days.
There are residential blocks very close by, will the unit disturb neighbours?
We select very-low-noise units and position the outdoor compressor so hot discharge air does not blow directly at neighbouring balconies.
Roofs here are safe and easy to build on, what do you need from us?
Tell us the roof condition, available space and distance from the mosque entrance, and confirm the building management approves if the roof is shared.
