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 Tadamun's mosques are modern buildings with spacious halls and high ceilings, located in the south facing intense direct heat and seasonal desert dust. The system must handle high thermal load year-round, especially in summer, and air filtration needs constant care because dust enters easily through openings and doors. Outdoor units have more space available around the mosque.
Al Tadamun sits in southern Jeddah, a modern district with large contemporary mosques near the surrounding desert.
Most mosques here use powerful central AC systems with multiple outdoor units to cover large areas.
The AC setup in Al Tadamun
- 1
Powerful multi-unit central AC system
Large areas require multiple outdoor units connected to a single central distribution for consistent cooling throughout.
- 2
High-efficiency air filters
The filtration uses multi-stage filters to block desert dust and maintain coil efficiency.
- 3
Distributed air outlets on ceiling and walls
The distribution network delivers cold air through multiple ceiling and wall outlets for full coverage without harsh draughts.
Before the visit

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.
With intense southern heat in summer, what cooling capacity do we need?
We calculate capacity based on the hall's area, ceiling height and extreme outside temperature, selecting units with adequate power for steady cooling even at peak heat.
Seasonal desert dust enters the mosque, how do you protect the system?
We fit high-quality air filters at the external inlet and recommend regular changes every month or two depending on dust intensity.
Regular servicing matters in extreme heat, how often should we clean the system?
We advise cleaning the evaporator and condenser coils every three months in the south due to extreme heat, and replacing filters monthly or every two months.
Wide open spaces around the mosque, where do you place multiple outdoor units?
We review available roof and rear spaces and position units to ensure good ventilation and evenly distributed load.
