When a mosque needs a specialist approach

  1. 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. 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. 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.

  • Your 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.

How we work

How we work

  1. 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. 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. 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. 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.

Ductwork, rooftop units and diffusers, from work we've completed in Jeddah.

  • Galvanized rectangular duct trunk with branch takeoffs and round diffusers, hung from a black ceiling, a Carrier unit visible behind — interior finishing stage.
  • Round diffusers and a spiral duct trunk in a tiled stairwell service shaft.
  • Rooftop ductwork and an exhaust fan, with Jeddah buildings in the background.
  • Rooftop packaged AC units with rectangular duct transitions, city buildings behind.
  • Insulated rooftop duct run beside a packaged unit, a warehouse roof in the background.
  • A grid of round diffusers in an open-plan office ceiling, mid-construction.
  • An insulated rooftop duct elbow, against a mountainous backdrop.
  • Large insulated ductwork running along a factory ceiling, with workers visible below.
  • A yellow round diffuser mid-installation, with spiral duct and a suspended ceiling grid.
  • Duct insulation wrap in progress on a construction site, bare duct still exposed.
  • A black-painted duct trunk with round diffusers and track lighting, in a finished retail interior.
  • An indoor AHU unit connected to round ductwork in a mechanical plant room, exposed concrete ceiling.

What sets this district apart

Al Bawadi mosques in central Jeddah stand in mixed-age districts, some newer buildings and some older, with halls varying from medium to fairly large. This variety calls for flexible solutions between central AC and multiple splits based on hall size and available budget. High humidity in central Jeddah and intense summer heat demand systems able to recirculate air efficiently and drain excess moisture without mould growth.

Al Bawadi sits in central Jeddah, a mixed-age district with mosques of varied hall sizes and configurations.

Al Bawadi mosques use either central AC or multiple connected split units, with outdoor units typically mounted on roofs or in tight gaps between buildings.

The AC setup in Al Bawadi

  1. 1

    Medium central AC for fairly large halls

    Larger Al Bawadi mosques benefit from a simple central system with exposed or minimal concealed ducts covering main prayer rows.

  2. 2

    Multiple split units for smaller or older halls

    Smaller or older mosques rely on two or three split units spread to avoid intrusive noise.

  3. 3

    Enhanced moisture drainage for high humidity

    High humidity in Al Bawadi demands an extra drain pan and insulated drainage piping to prevent leaks and mould.

Before the visit

Before our visit in Al Bawadi

  1. 1

    Confirm hall size and ceiling height

    Tell us approximate hall dimensions and height, and whether the ceiling is flat or domed, so we can determine the best system.

  2. 2

    Inspect available roof and gap spaces

    Check the main roof, side gaps and ledges, and any spot where you'd prefer the outdoor unit before our visit.

  3. 3

    Coordinate with maintenance officer

    Arrange best times away from prayer slots, and let us know if there are other fixtures on the roof to avoid.

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.

Our mosque hall is medium-sized, is multiple split AC better than central?

It depends on hall size, ceiling height and budget. Multiple splits are easier to install but central is better for even distribution. We visit to assess and advise what suits your situation.

Crowded roofs and tight gaps, where should we place the outdoor unit?

In Al Bawadi, roofs often have other fixtures, so we check options together: secondary roof space, side gap, or safe exterior wall before installation.

Central Jeddah humidity is very high, can the AC handle it?

Yes, but coils and ducts need regular cleaning every six months to drain excess moisture and prevent mould.

AC servicing, do I need a maintenance contract or pay per visit?

We offer both: a periodic maintenance contract covering cleaning and checks every three months, or call-out service when needed. Choose based on your mosque's needs.
