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.

Some of our work

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.

What sets this district apart

Al Tha'alibah is a growing residential area south of Jeddah with relatively modern mosques in developing neighbourhoods, and the construction is newer than old downtown areas. Prayer halls have reasonable ceiling heights and adequate space for modern building, enabling a well-planned central AC system with ideal ductwork. Streets are wider than the old city and team and equipment access is much easier. Heat and humidity are present but less severe than coastal areas, and quarterly servicing keeps the system in top condition.

Al Tha'alibah lies in south Jeddah, a growing modern residential area with contemporary mosques, wide streets and planned development.

Most modern Al Tha'alibah mosques use central AC with concealed ducts and balanced ceiling distribution due to good architectural planning and reasonable ceiling heights.

The AC setup in Al Tha'alibah

  1. 1

    Comprehensive central system with hidden ducts

    Most modern Al Tha'alibah mosques feature hidden ducts in ceilings and walls distributing cool air with high efficiency and aesthetic appeal.

  2. 2

    Outdoor units on spacious roofs

    Modern mosques have spacious roofs ideal for placing condensing units away from the front facade and adjacent residential areas.

  3. 3

    Smart monitoring and protection system

    Modern systems allow adding smart temperature and humidity monitoring with fault alerts, enabling proactive maintenance.

Before the visit

Before our visit in Al Tha'alibah

  1. 1

    Obtain the mosque's architectural and engineering plans

    Request from mosque management a copy of the engineering plans to study ductwork routes, ceiling space and electrical points before the visit.

  2. 2

    Confirm safe access to roofs and duct routes

    Inspect the ceiling, roofs and spaces designated for ductwork, confirming the team can safely access and move through without obstacles.

  3. 3

    Schedule work away from peak prayer times

    Coordinate with mosque management to select days and times that avoid the five daily prayers and main weekly gatherings.

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 new with modern design, how do you select the right system?

We review the architectural plans, ceiling and hall, and select a central system with hidden ducts balanced across rows and side aisles.

The streets here are wide, is access to the mosque easier during installation?

Yes, Al Tha'alibah's wide streets and planned development allow easy access for our team and equipment, reducing installation time and disruption.

The heat is severe but not coastal, how does that affect the system?

The system needs adequate capacity for intense heat but without salt-protection measures; standard quarterly servicing is sufficient.

Modern ceilings are strong, can heavy ductwork be safely added?

Yes, modern concrete ceilings safely support duct and indoor unit weight, but we confirm structural design before starting work.
