Cooling fit for a mosque
Mosque HVAC in Abhur Al Janoubiyah

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
Abhur Al Janoubiyah is a medium-density coastal area with modern mosques in residential and commercial neighbourhoods, prayer halls smaller than northern towers but facing intense coastal heat and humidity. Salt and moisture in the air speed up dirt buildup in cooling outlets and coils, and accelerate metal corrosion, so the design must allow regular cleaning of outlets and ducts without shutting down during prayer times.
Abhur Al Janoubiyah is a coastal neighbourhood in north Jeddah with medium-sized mosques with open prayer halls and direct exposure to sea moisture and salt.
Most Abhur Al Janoubiyah mosques use straightforward central cooling with multiple outlets and require high-frequency maintenance due to salt and moisture.
The AC setup in Abhur Al Janoubiyah
- 1
Central system with flexible sections for cleaning
Air ducts are arranged in sections that come apart easily for regular cleaning without full shutdown.
- 2
Outdoor unit with rust-resistant coating
The outdoor unit uses materials and coatings that resist salt and coastal moisture to prolong system life.
- 3
Outlets protected against moisture seepage
Outlets and grilles are angled for proper drainage to prevent water and moisture pooling inside ducts.
Before the visit
Before our visit in Abhur Al Janoubiyah
- 1
Measure the prayer hall and courtyard
Determine the enclosed prayer hall area and any adjoining open courtyard so we design the system to handle both zones efficiently.
- 2
Confirm access for regular inspection
Ensure drainage points and removable sections are placed in safe, easily accessible spots for regular maintenance.
- 3
Coordinate a regular maintenance schedule with management
Agree with mosque management on monthly or bimonthly inspection and cleaning times that avoid prayer hours and events.

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.
Coastal humidity affects cooling efficiency, how do you protect the system?
We select units with strong dehumidification and design drainage points elevated from floor level to prevent water pooling in ducts.
Can you clean outlets and ducts without stopping the system during prayer times?
We design ductwork with sections that come apart and reassemble easily so parts can be cleaned without stopping the whole system.
Sea salt corrodes metals, do you use corrosion-resistant materials?
We choose ducts and outdoor units with rust-resistant coatings and recommend regular inspections of salt-exposed parts.
The prayer hall opens onto an outdoor courtyard, does this complicate the design?
No, but we design outlets so cold air does not escape into the open courtyard, and choose air speeds that balance cooling with comfort.
