When you need evaporative cooler duct
- 1
A large workshop or warehouse
Large industrial spaces get very hot in Jeddah summers and split units are expensive to run there. An evaporative cooler with distribution duct brings air to work areas at lower running cost, provided the space is ventilated and not sealed shut.
- 2
A majlis tent or seasonal space
Outdoor majlis areas and seasonal tents do not suit split AC units because of the structure. Evaporative duct delivers a cool air stream as long as the space is open enough for air changes, which the survey confirms.
- 3
Old duct with poor airflow
Old sheet duct cracks over time and air leaks from the joints before reaching the space. On site we check whether the problem is leaking duct, poor distribution, or the cooler size itself.
Who it's for
Need to cool a large workshop at reasonable running cost
We survey the workshop and check its ventilation, then run galvanised duct from the roof cooler to the work areas with exhaust openings that keep air moving through the space.
Ask on WhatsAppYou have an outdoor majlis that needs seasonal cooling
We check how open the majlis is and assess its structure, then design the duct route and exhaust openings so cool air reaches the seating area without humid air building up inside.

- Weatherproof roof collar fitted
- G90 galvanised duct runs
- Branch and air outlet connections
- Exhaust openings for air changes
- Airflow check after start-up
How we work
How we work
- 1
Site survey first
We visit, measure the space and check how open it is, because evaporative cooling needs enough ventilation; without it humidity rises inside and the cooling effect drops.
- 2
Plan the duct route
We plan the main duct run, branches, air outlet positions and exhaust opening locations, and show you the layout before any work starts.
- 3
Install duct and seal roof
We open the roof, fit and seal the collar against leaks, then run the galvanised duct and hang it on proper supports so it does not sag.
- 4
Start-up and test
We run the evaporative cooler and check that air reaches every outlet and that the exhaust openings are working so fresh air is visibly moving through the space.

What sets this district apart
Al Abeer is a modern northern district of villas and residential blocks with contemporary designs and accessible roofs. The buildings here are more spaced than central areas, and open floor plans with high ceilings make evaporative duct a viable choice if adequate natural ventilation exists. The northern location means cooler temperatures than coastal zones, though desert dust calls for regular filter maintenance.
Al Abeer sits in north Jeddah, a modern residential district of well-spaced buildings with clear, accessible roofs.
Most villas and apartment blocks in Al Abeer have level roofs and regular drainage, making the cooler and duct run easier to install safely.
The AC setup in Al Abeer
- 1
Roof cooler with galvanised duct for open spaces
Modern villas and apartment blocks in Al Abeer can handle air distribution via galvanised duct to multiple rooms if the layout is open.
- 2
Regular exhaust vents in each room
Regular exhaust openings keep air circulating and humidity balanced throughout the villa or apartment block.
- 3
Water tank on roof with safe drainage
The tank is mounted on the roof next to the cooler, with excess water draining safely away from the building.
Before the visit
Before our visit in Al Abeer
- 1
Check the villa roof and access stairs
Let us know if the stairs are safe and the roof is level and clear of obstacles before installation day.
- 2
Confirm water and power are available on the roof
The cooler needs a water point and power outlet on the roof, so confirm they exist or can be safely run before the visit.
- 3
Verify the roof's stability and pitch
A stable, level roof makes installation and maintenance easier, so check for no cracks or steep pitch that would affect cooler and duct placement.

FAQ
Questions about Evaporative (desert) duct installation
Does evaporative cooling work in Jeddah in summer?
Evaporative cooling relies on water evaporation and weakens when humidity is high. In Jeddah, humidity is higher near the coast and lower inland. The survey decides whether the space and the season are suitable, which is why we do not start before visiting the site.
Why do exhaust openings matter as much as the duct runs?
An evaporative cooler pushes fresh air in continuously. Without an exit path, humid air builds up inside and the felt temperature rises. Properly sized exhaust openings keep air moving through, not piling up, and that is the core of how this type of cooling works.
What sheet do you use for the duct?
We use G90 galvanised steel sheet, which resists rust in Jeddah's humid and salty air. The duct sections are formed in our workshop before being taken to site, then hung on supports along the run to stop them sagging.
Can one cooler supply duct to more than one area?
Duct can be branched from one unit to more than one outlet, but each branch reduces the airflow at every opening. The survey decides whether the cooler has enough output for the total area, or whether a separate unit for each wing is the better answer.
Can evaporative cooler duct run through a false ceiling?
Evaporative cooling depends on continuous air movement and exchange, which requires exhaust openings in the same space the duct serves. A false ceiling restricts that flow unless dedicated openings lead air out of the building. The site survey decides whether the structure allows it, because the duct run and the exhaust are designed together as one system, not separately.
Is evaporative duct suited to modern villas in Al Abeer?
Yes, if the villa has open spaces and good natural ventilation. The site survey determines whether the layout and airflow can support this system.
How do you get the cooler and heavy galvanised duct up to a villa roof?
Our team lifts the cooler and duct using proper lifting gear, and we agree on the roof access point and securing the workspace before installation.
Desert dust is heavy in Al Abeer, how often should I change the filter?
Desert dust speeds up filter clogging, so we recommend checking monthly and replacing as needed, especially in summer.
Will my villa roof support the weight of the cooler, duct, and water?
It depends on the roof's original structure, and the survey confirms load capacity before any installation.
