Cooling fit for a mosque
Mosque HVAC in Al Buddur
In Al Buddur, east Jeddah, mosques have relatively modern layouts but many still operate with aging cooling systems unsuited to growing congregations. Alrabih upgrades cooling to ensure even air distribution and improved energy performance.

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 Buddur is a mid-age district with ongoing urban development, and many of its older mosques now host larger congregations than originally designed for. Most mosque cooling systems need upgrading to cope with rising worshipper numbers and the increasing eastern heat. Upgrades include adding extra cooling units or replacing old ones with more efficient systems, without disrupting the mosque's architecture or décor.
Al Buddur lies in east Jeddah, a middle-aged residential area with both older established mosques and newer complexes.
Most older Al Buddur mosques have basic cooling units or aged ductwork needing replacement or capacity additions.
The AC setup in Al Buddur
- 1
Gradual replacement of older units
New cooling units are installed alongside old systems, with old units phased out gradually as the new ones take over full responsibility.
- 2
Upgraded insulated ductwork
Old rusted ducts are replaced with modern insulated ductwork offering better efficiency and reducing heat loss in passages.
- 3
Smart controls for improved efficiency
Modern control systems adjust cooling based on actual need, saving energy and extending the lifespan of new units.
Before the visit
Before our visit in Al Buddur
- 1
Gather history of old system and current issues
Send details of the current system's age, recurring faults, and areas that stay hot for an initial assessment before the visit.
- 2
Clarify priority areas for cooling
Identify areas in the mosque needing faster cooling first (such as the prayer niche or front worshipper rows) to prioritise the upgrade phases.
- 3
Confirm space availability for new units
Check that the roof or external wall has space for new outdoor units without clashing with adjacent buildings.

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 old and has more worshippers now; how do you upgrade the system without closing it?
We upgrade in stages: install additional cooling units alongside the old ones, gradually modify ducts, and keep the old system running until the new one is complete.
The old ducts have rusted and leak; do they need complete replacement?
We assess each duct in detail; some can be repaired with insulation and patching, others need partial or full replacement depending on rust and leak severity.
Do you recommend complete system replacement or gradual upgrading?
It depends on your current system's condition and budget, but we recommend gradual upgrading as it reduces downtime costs and allows better planning for new units and ducts.
Al Buddur gets intensely hot in summer; how do you size the new units?
We calculate cooling load based on peak summer heat and expected worshipper numbers, then select units that exceed the minimum slightly to ensure comfort on the harshest days.
