When your restaurant needs a specialist
- 1
Kitchen smells reaching diners
When the extract hood pulls out more air than is replaced, the kitchen goes negative and draws air from the dining room, bringing smells with it. The answer is calculating the volumes and delivering make-up air close to the hood.
- 2
Dining room stays warm despite the AC
A full dining room in Jeddah's humid summer raises heat and moisture load noticeably. Design must account for peak occupancy, and the right diffuser layout achieves even cooling across tables, not cold near the duct and warm in the corners.

Repeated breakdowns in kitchen AC units
Grease vapour from the burners settles on evaporator coils and blocks airflow, raising pressure and stressing the compressor. Placing the unit away from grease currents and scheduling coil cleaning reduces this damage significantly.
Who it's for
Opening a new restaurant that needs a full HVAC system
We design the cooling and make-up air system from scratch to match your kitchen and dining layout before you open.
Ask on WhatsAppYour restaurant is running but smells are reaching the tables
We survey the existing system, measure pressure between kitchen and dining, then correct the fault by adding make-up air or adjusting the air balance.

What the work covers
- Kitchen and dining pressure survey

- Diffuser layout for dining
- Ductwork to SMACNA standards
- Air balance commissioning
How we work
How we work
- 1
Site and kitchen survey
We visit, measure the spaces, review the existing extract hood and burner positions, and find where negative pressure is occurring before any design work.
- 2
Design and equipment selection
We design the make-up air and cooling systems together, and select units from Carrier, YORK, General, Midea, Gree or Smart Gold to suit the space and the load.
- 3
Duct fabrication and installation
We fabricate ducts in our workshop from G90 galvanised sheet to precise sizes, install the units, and run Mueller copper in runs of up to 30 metres without welded joints, insulated with Armaflex.
- 4
Balancing and handover
We run the system and adjust dampers until the kitchen sits at slight negative and the dining room at slight positive, confirming that doors open easily and no kitchen smell crosses to the guests.
Integrated design or separate units with no balance?
| Alrabih | The usual way | |
|---|---|---|
| Make-up air | Calculated and delivered to the hood | Usually not addressed |
| Dining pressure | Slight positive, no smell transfer | Negative, pulls kitchen air in |
| Coil protection | Unit placed away from grease | Repeated breakdowns |
| Cooling spread | Diffusers sized for full occupancy | Uneven, warm corners |
| Kitchen ductwork | Fabricated in-house from G90 sheet | Off-the-shelf sizes, poor fit |

What sets this district apart
Abhur Al Janoubiyah's restaurants and cafés range from villa extensions sharing the house's air supply to independent modern buildings. The high humidity close to the sea causes rapid dew buildup on coils and cuts cooling efficiency, especially when strong kitchen extraction pulls humid outside air in. We need effective dehumidification working alongside cooling, and robust protection of coils and pipes from rust and grease corrosion.
Abhur Al Janoubiyah is a modern coastal district north of Jeddah, mixing residential villas with small to medium commercial projects close to the beach.
Restaurants and cafés here either connect to existing villa AC systems or have separate new units, and coastal humidity demands frequent coil maintenance.
The AC setup in Abhur Al Janoubiyah
- 1
Pressure separation for villa-attached café
Where a café adjoins a villa, we install an air barrier and separate fan to prevent cooking odours and grease seeping into the family areas.
- 2
Dedicated new units for standalone cafés
Standalone cafés need either a powerful central AC system or multiple advanced split units with specialist dehumidification because of the high coastal humidity.
- 3
Salt-resistant and corrosion-proof protection systems
Close to the beach, we specify premium copper coils and pipes with protective coatings, plus protective screens on outdoor units.
Before the visit

Clarify if the café is attached or independent
If the café is attached to the villa, specify the wall divisions and doors between them, and send a photo of the internal layout showing current ventilation routes.
- 2
Ensure roof and outdoor unit access for the team
The roof may be above the villa or café directly; ensure the team can safely access and service the outdoor units and exhaust ducts.
- 3
Coordinate with both café manager and villa owner
If they are separate parties, get approval from both before the visit, as work may affect both the café and villa operations.

FAQ
Questions about Restaurant & cafe HVAC
What is the difference between make-up air and kitchen air conditioning?
Make-up air replaces the volume the hood extracts, its purpose is pressure balance not necessarily cooling. Kitchen air conditioning tackles burner heat and lowers temperature for the staff. Both may be needed, and the site survey determines which your kitchen requires.
Do outdoor seating areas need a different approach in Jeddah?
Yes. In Jeddah's heat and humidity, fans alone are not enough during peak months. The right option depends on whether the space has an open roof or a partial enclosure and how large the area is. We assess the spot and propose suitable units after the survey.
How are AC coils protected from kitchen grease?
The first step is design: we position kitchen units in airflow paths away from the grease rising off the burners. In preventive maintenance contracts we schedule pressure coil cleaning before build-up raises stress on the compressor, because early cleaning is simpler and less costly than a repair.
Can existing ductwork in an operating restaurant be repaired or does it need replacing?
The decision follows a duct inspection: we look for air leaks, grease build-up inside, and sheet corrosion from Jeddah's salty air. If the structure is sound we seal joints with Foster sealants and re-insulate with Kimmco. If not, we fabricate new sections in our workshop and replace the damaged runs.
Does a packed dining room during peak season affect how the AC performs?
Yes, every person in the room adds heat and moisture, and this is significant in Jeddah's summer. Design therefore accounts for full occupancy load, not average attendance, and diffusers are positioned to deliver even cooling across all tables. The exact layout is confirmed after the site survey.
My café is attached to my villa, how do you separate the AC between them?
We install a pressure barrier and air seal between the villa and café sections, and add a separate fan for the café with its own supply and extraction line, so odours and humidity don't cross over.
Sea salt and moisture corrode units quickly, how do you protect them?
We specify equipment with corrosion-resistant coatings, fit protective screens on outdoor units, and recommend annual cleaning of coils and pipes to remove salt and mould.
The kitchen extract pulls humid sea air directly in, is that normal?
Yes, but it increases dehumidification load. We recommend fitting a desiccant filter before air enters the kitchen, and balance the supply and extraction so coils don't get overwhelmed.
Does Abhur's humidity cause mould in the drain pan and pipes?
Yes, high humidity and warmth accelerate mould growth in drains. We recommend maintenance every two months, fit a drain with wide holes on a strong slope, and add a biocide tablet to the pan.
