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.

| 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 Muhammar's mosques vary: some are older buildings with mid-sized halls and original AC systems needing continuous servicing, others are newer with modern central units. Coastal humidity affects them equally, especially drains and condensers. Coordinating with diverse mosque administrations requires flexible maintenance scheduling around varying prayer times and religious programmes. Work on older systems may need specialised parts or extra technical consultation to ensure uninterrupted service.
Al Muhammar is an east-side neighbourhood with both old and new mosques, running diverse AC systems that need tailored servicing for each.
Al Muhammar mosque systems range from older small rooftop units to modern central systems, requiring maintenance expertise in both types.
The AC setup in Al Muhammar
- 1
Older small-capacity units
Some older mosques run small rooftop units of 1.5 to 3 tonnes, needing careful servicing and specialised parts.
- 2
Newer medium central systems
Newer mosques have medium central units of 3 to 5 tonnes, with reasonable ductwork balancing simplicity and efficiency.
- 3
Humidity-exposed condensers and drains
All systems face coastal humidity, so condensers and drains need regular cleaning to prevent blockage and moisture accumulation.
Before the visit
Before our visit in Al Muhammar
- 1
Assess the type and condition of older systems
Before arrival, gather unit data (type, age, capacity) and any history of faults or known parts, to ensure necessary components are on hand.
- 2
Schedule flexibility with mosque administration
Contact the mosque administration to agree on a time suited to varied religious schedules, with backup dates in case of sudden clashes.
- 3
Arrange facilities and technical support
Ensure adequate power, staff for coordination, safe access to roof and ducts, and possibly on-site monitoring during operation.

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 old and the AC is vintage, can you service and repair it?
Yes, we have experience with both old and new systems. We may source specialised parts for some older units, but we ensure uninterrupted operation.
Coastal humidity increases mosque faults, how do we reduce it?
We recommend monthly cleaning of the condenser and drains at minimum in summer, and checking drainage lines for blockage. We may add a dehumidifier unit during intense seasonal periods.
How often should we clean the mosque's AC systems per year?
On the coast with high heat, we recommend a full inspection before summer (May), condenser and drain cleaning every two months, and a final check before winter.
Do you help schedule regular maintenance for the mosque?
Yes, we propose regular maintenance contracts that balance cooling needs with prayer schedules and religious programmes, with quarterly or semi-annual visits as needed.
