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 Tilal is a relatively modern district with architecturally sophisticated mosques featuring high spacious halls, suspended ceilings and contemporary interior design, located in an area facing intense year-round heat due to its eastern position. Modern construction allows efficient, precisely distributed duct design that uses the ceiling voids planned into the original architecture, making installation smoother than in older districts, but system capacity must tackle the intense eastern summer heat.
Al Tilal is in east Jeddah, a modern residential district with architecturally advanced mosques.
Most Al Tilal mosques have high-efficiency central systems requiring precise design to handle the intense eastern heat exposure.
The AC setup in Al Tilal
- 1
High-capacity central AC with enhanced efficiency
The spacious, high-ceilinged halls in Al Tilal need high-capacity, energy-efficient chillers to handle intense eastern heat.
- 2
Precision-distributed ducts with zone control
Ducts are precisely routed to distribute cold air evenly across all prayer areas, with separate temperature control for different zones.
- 3
Advanced thermal insulation and silencers
Ducts are insulated with robust thermal materials to preserve air coolness, and modern silencers minimise operational noise.

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 needs fast cooling in summer when the hall fills suddenly, can the system handle sudden load?
We select chillers oversized by a margin for the expected peak load, allowing the system to cool rapidly when worshippers gather quickly.
High ceilings and open halls make duct routing difficult, how do you run the ducts?
We use the ceiling void and structural columns planned into the suspended ceiling, designing multi-outlet ducts with many small vents to ensure smooth coverage without harsh draughts.
Extreme eastern heat reaches 55 degrees, does it affect system performance?
We specify materials and designs rated for extreme heat, and position the outdoor unit with ventilation that prevents it absorbing extra heat from adjacent walls or surfaces.
How often do you need to service it, and are the wiring and ducts safe from heat damage?
We recommend servicing at the start and mid-summer, with electrical runs and insulation specified in heat-rated materials.
