Cooling fit for a mosque
Mosque HVAC in Al Ushairiyah
In Al Ushairiyah, east Jeddah, mosques in new, dense residential areas need an AC system balancing cooling efficiency and quiet operation. Alrabih designs the system to withstand intense eastern heat and distribute air evenly without disturbing neighbouring residents.
- Even distribution
- Quiet units

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?
| Alrabih | The usual way | |
|---|---|---|
| Air distribution | Even across every row | Cold front, hot back |
| 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 Ushairiyah is a relatively new east Jeddah district with high residential density, regular streets and modern apartment blocks. Mosques here typically sit between very closely spaced buildings and are surrounded by flats on all sides. Temperatures in the east may be slightly higher than the west due to longer morning sun exposure. The system must deliver strong cooling but with robust sound insulation and proper water drainage, as humidity peaks in summer. Limited space demands precise siting of the outdoor unit.
Al Ushairiyah lies in east Jeddah, a modern, densely residential district with mosques surrounded by very closely spaced apartment blocks.
Most Al Ushairiyah mosques are surrounded by flats on all sides, making outdoor unit placement extremely demanding.
The AC setup in Al Ushairiyah
- 1
Central system prioritising roof placement
If possible, the outdoor unit sits on the mosque roof, well away from surrounding flat windows.
- 2
Isolated and reliable drain line
The drain line is thermally insulated and directed to a safe drainage area to prevent water leakage onto neighbouring flats.
- 3
Outdoor unit with high sound insulation
The outdoor unit mounts on a vibration-isolated base and a sound shield may be added if the location is near windows.
Before the visit
Before our visit in Al Ushairiyah
- 1
Identify the roof and any tight gaps
Tell us if the mosque has a safe roof for the unit, and the dimensions of any tight gaps between the mosque and adjacent buildings.
- 2
Check drain line routing and water location
Identify existing drainage pipes and the safe point to discharge AC condensation away from neighbouring flats.
- 3
Note the surrounding flats' window positions
Note the positions of surrounding flat windows so we avoid placing the outdoor unit directly in front of any window.

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 is surrounded by flats on all sides, where can we site the outdoor unit?
We examine all options: the roof, the tight gap between mosque and adjacent building, or even the outer wall position. We choose the location that minimises noise to residents.
Heat is more intense in the east, how do you ensure adequate cooling?
We calculate thermal load based on eastern sun exposure and local data, selecting an outdoor unit with capacity sufficient to handle peak loads.
Humidity is high, does this cause water leakage from the drain pan?
Yes, eastern humidity increases condensation. We design a strong drain line with proper slope and insulation, and check the pan regularly.
If we cannot find a safe outdoor unit site, is there an alternative?
In very difficult cases, we may recommend an indoor unit (air handler) or a water-distribution cooling system instead of air, but this requires full engineering review.
