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?

| 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 Muzaira'ah hosts modern mosques with spacious halls and high ceilings, exposed to severe heat during long daylight hours, especially in summer when temperatures exceed 45°C. Seasonal humidity, dust and sand from open areas add further system challenges. Precise central design distributes cold air evenly across all hall zones, with effective dehumidification of excess moisture.
Al Muzaira'ah is a modern residential district with contemporary spaced buildings north of Jeddah, facing severe heat load especially during summer months.
Most Al Muzaira'ah mosques use large-capacity central systems with extended ducts to handle the intense heat load.
The AC setup in Al Muzaira'ah
- 1
Very high-capacity central system
Al Muzaira'ah mosques need exceptionally high-capacity chillers and wider-diameter ducts to handle severe summer heat load.
- 2
Powerful dehumidification with advanced filtration
Dust and high humidity require robust dehumidifiers and high-efficiency filters to protect indoor air quality.
- 3
Extended ducts with distributed vents
Spacious halls with high ceilings need extended duct networks and multi-location vents to ensure uniform cooling.
Before the visit
Before our visit in Al Muzaira'ah
- 1
Inspect roofs and existing thermal insulation
Check roofs and exterior walls to assess thermal insulation quality and determine if upgrades are needed before installation.
- 2
Take precise measurements of the hall and adjoining areas
Measure hall height, ceiling heights and all area dimensions to calculate correct central unit capacity and duct sizing.
- 3
Coordinate work schedule with mosque management
Fix installation and testing periods away from prayers and events, accounting for future regular maintenance schedules.

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.
Summer temperatures exceed 45°C; how do you design for such severe heat load?
We select central units and chillers with above-standard capacity, and recommend robust thermal insulation on roofs and exterior walls.
Dust and sand from open areas clog the system; how do you protect it?
We install high-efficiency air filters at the intake and schedule regular maintenance to clear dust from coils and ducts.
High humidity plus intense heat increases mould growth; does this affect the hall?
Yes, so we install powerful dehumidifiers and schedule regular duct and coil cleaning to prevent mould and odours.
The prayer hall is very large; how do you distribute cold air evenly?
We use extended ducts with ceiling and wall vents distributed throughout, and zone dampers allow adjustment in each area as needed.
