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
Jawharat Thuwal sits in far northern Jeddah on an isolated coastal strip, hosting modern mosques with spacious halls and high ceilings facing severe heat from sun and sea. The remote location, high coastal humidity and intense summer heat make effective cooling essential, requiring central systems of exceptional capacity and regular upkeep. The design accounts for relative isolation and harsh coastal environment.
Jawharat Thuwal is a remote coastal residential district north of Jeddah with modern spaced buildings, exposed to severe heat from the shoreline and marine environment.
Jawharat Thuwal mosques need exceptionally large central systems, extended ducts and regular maintenance due to harsh coastal conditions.
The AC setup in Jawharat Thuwal
- 1
Exceptionally high-capacity central system
Jawharat Thuwal mosques with high ceilings and severe coastal exposure need exceptionally large chillers and greatly extended ducts.
- 2
Advanced corrosion and moisture protection
High marine humidity requires protected piping, robust filters and regular cleaning to prevent rust and mould buildup.
- 3
Monitoring and periodic maintenance system
The remote location requires periodic monitoring and comprehensive maintenance contracts to ensure uninterrupted system operation.
Before the visit
Before our visit in Jawharat Thuwal
- 1
Inspect thermal insulation on roofs and walls
Harsh coastal conditions require very strong insulation, so assess current insulation quality and determine if upgrades are essential.
- 2
Measure spaces and heights with high precision
Take precise measurements of hall height and surrounding areas, and identify duct routes and available spaces for units.
- 3
Commit to a long-term periodic maintenance contract
The remote location requires a comprehensive pre-scheduled maintenance contract covering regular cleaning, inspection and repairs.

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.
Remote location and extreme heat; is system maintenance more difficult?
Yes, we recommend scheduled regular maintenance contracts coordinated in advance, ensuring spare parts and quick service despite the distance.
High marine humidity speeds corrosion; how do you protect pipes and equipment?
We use corrosion-resistant copper piping and schedule regular coil and duct cleaning to prevent rust and mould.
Extreme heat may limit cooling capacity; are there efficiency boundaries?
Yes, outdoor temperatures above 50°C may reduce cooling efficiency, so we select high-rated units and strongly recommend robust thermal insulation.
The hall is far from the city; how do you ensure continuous maintenance?
We sign comprehensive periodic maintenance contracts with trained teams visiting on set schedules, and provide an emergency hotline for urgent queries.
