Cooling fit for a mosque
Mosque HVAC in Al Atheer
In Al Atheer, south Jeddah, mosques need cooling that distributes cold air evenly across wide prayer halls and packed side aisles during peak prayer times. Alrabih designs quiet air-delivery systems that cover high columns and domes without disrupting worship.

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.

What sets this district apart
Al Atheer's mosques are relatively modern with large halls, a central mihrab and tall columns requiring even cold-air distribution, especially on Fridays and religious holidays when the hall fills rapidly. The open interior layout and high ceiling demand a powerful central air system with carefully routed ducting to prevent harsh drafts on worshippers, and noise control is critical because mechanical sounds distract from the sermon and recitation.
Al Atheer is in south Jeddah, a newer residential district with architecturally spacious mosque halls.
Most Al Atheer mosques have central AC systems with overhead distribution ducts and need regular servicing during the hot season.
The AC setup in Al Atheer
- 1
Central AC system with large chillers
The spacious, high-ceilinged halls in Al Atheer need high-capacity chillers, typically mounted on the mosque roof or in a dedicated plant room.
- 2
Overhead distribution ducts with balanced vents
Ducts run through the ceiling void and suspended ceilings, with carefully positioned vents ensuring cold air spreads evenly across the hall.
- 3
Thermostats and noise control
Smart thermostats and duct silencers are installed to minimize operational noise and maintain the quiet needed during prayers.
Before the visit
Before our visit in Al Atheer
- 1
Obtain the mosque's architectural drawings
Provide or share the mosque's floor plans and ceiling layouts so we can understand the hall configuration and identify space for duct runs.
- 2
Agree on the outdoor unit location and prepared area
Coordinate with the mosque administration on where the outdoor unit will be mounted and whether a plant room or rooftop space is ready.
- 3
Confirm engineering support and maintenance coordination
Arrange a maintenance schedule with the mosque and assign a contact person to report any faults and coordinate future servicing.

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.
How do you distribute cold air evenly across the large hall and side aisles?
We design multi-outlet distribution ducts from the central plenum and balance the vents in each zone to ensure even flow without harsh draughts.
Can you install the system without drilling into the main prayer-hall ceiling?
This depends on the mosque's structure and available ceiling void. We conduct a technical visit to survey the layout and identify the best duct routing.
The extreme heat in Al Atheer reaches 50 degrees, can the system handle that?
We select chillers with cooling capacity rated for the intense heat in the area, and the design accounts for internal heat from the congregation.
How do you route the wiring and ducts from the outdoor unit into the mosque?
We route the pipes and power runs through prepared openings in the mosque walls or via insulated protective ducts, keeping the ductwork hidden from view wherever possible.
