Cooling fit for a mosque
Mosque HVAC in Al Thaghr
Mosque cooling in Al Thaghr, south Jeddah, serves mosques close to the coast in a mixed industrial and residential area. Coastal heat and salinity demand robust systems and corrosion-resistant materials to sustain long-term performance.
- 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.

- 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 |

From Al Shiraa and Al Yaqout in the north to Al Thaghr and Al Quraiyat in the south, with our base in Al Aziziyah.

What sets this district apart
Al Thaghr is a southern area near the waterfront and industrial zone with several mosques serving residents and factory and warehouse workers. The climate is harsher due to coastal exposure and direct sun on buildings, and salt humidity accelerates corrosion in condensers and pipework. The AC system must be sized with extra margin to handle severe heat load and high humidity, and regular servicing is critical to clean and protect metal components from salt and rust.
Al Thaghr sits in south Jeddah near the coast and industrial zone, a mixed area of residential, manufacturing, storage and port facilities.
Al Thaghr mosques need robust central or multiple-split systems, and outdoor unit installation requires materials resistant to salt and high humidity.
The AC setup in Al Thaghr
- 1
High-performance central system with salt protection
Al Thaghr mosques need a robust central system with high-quality condensers and special treatment of metal parts to resist coastal salt and humidity.
- 2
Outdoor units elevated on concrete stands
Outdoor units are elevated on sturdy stands to protect them from groundwater and humidity pooling in rear courtyards or yards.
- 3
Galvanised materials and protective coatings
Pipes, brackets and external structures are selected in galvanised or salt-resistant coated materials to extend system lifespan.
Before the visit
Before our visit in Al Thaghr
- 1
Survey the site for water pooling and dampness
Survey the courtyard and rear space to identify safe mounting locations for the outdoor unit away from water pooling and excess dampness.
- 2
Assess direct sun exposure and salt-laden air
Consider the prevailing sea breeze direction and direct sun exposure on site, selecting the shadiest location possible to reduce corrosion and excess heat.
- 3
Agree with mosque management on monthly servicing schedule
Establish with management a monthly or bimonthly schedule for intensive servicing and cleaning, especially of condensers from salt and mould deposits.

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.
The mosque is near the port with very high salinity, does it damage the AC?
Yes, coastal salt corrodes metals quickly. We clean units and condensers more frequently and recommend galvanised or salt-resistant coated materials.
The heat here is intense, how do you size the system?
We calculate with a larger safety margin than usual to handle the severe heat load from the coast and direct sun, installing units rated for sustained operation at very high temperatures.
The mosque's rear courtyard is tight and the ground is damp, where do we place the outdoor unit?
We assess the site and elevate the outdoor unit on a raised concrete pad to avoid water pooling and dampness, or mount it on a wall away from water sources.
The mosque operates day and night for workers, does it need more intensive servicing?
Yes, continuous operation combined with heat and salinity calls for monthly or bimonthly servicing instead of quarterly to ensure system reliability and sustained performance.
