Restaurant & cafe HVAC
Restaurant & cafe HVAC in Al Zahra
In Al Zahra, west Jeddah, older and newer restaurants sit side by side in mixed-height buildings. The HVAC system needs precise pressure balance between kitchen and dining, with protection against both cooking grease and coastal humidity.

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.
- 3
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
- Make-up air for hood
- 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
Al Zahra is a relatively older district mixing older blocks and modern towers, with restaurants ranging from retrofitted older establishments to newly designed ones. Coastal humidity here is higher due to sea proximity, speeding mould growth in air ducts and drain pans, and cooking grease builds up faster. The system needs frequent filter, coil and drain maintenance to prevent leaks and odours.
Al Zahra lies in west Jeddah near the sea, a mixed district of older blocks and modern towers with diverse restaurants.
Older restaurants here typically used window or split units before upgrading, while newer ones use central systems with strong hoods.
The AC setup in Al Zahra
- 1
Central AC system for new restaurants with strong hood
Modern restaurants in Al Zahra use central systems supplying cool and balanced make-up air, with coils protected from grease and humidity.
- 2
Split or retrofit for older restaurants with clean air
Older restaurants may stay with upgraded split units plus additional hood and grease filters before the AC, to ensure clean air for diners and coil protection.
- 3
Enhanced drain pans for coastal humidity
We use specially designed drain pans with sloped drainage and check valves to prevent moisture pooling and mould growth in restaurants near the coast.
Before the visit
Before our visit in Al Zahra
- 1
Inspect old ducts and pans for mould and odours
Before the visit, check existing ducts and drain pans for mould or problems so we can estimate whether they need full replacement or cleaning.
- 2
Position hood and outdoor unit away from the sea-facing facade
If the restaurant is near the sea, we need to position the outdoor unit and hood away from salt air and high humidity as much as possible.
- 3
Agree with restaurant on scheduled maintenance from the start
Due to high humidity and grease, we agree with the restaurant owner on a monthly or bi-monthly maintenance plan starting from installation.

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.
The restaurant is older and humidity is high, does this affect the AC?
Yes, coastal humidity speeds mould growth in drain pans and air ducts, so we fit reliable drain valves and clean the system every one or two months to avoid odours and leaks.
The restaurant was old with a window AC, can we convert it to split or central?
Yes, we remove the old unit and install a new system (split or central) with balanced hood and grease filters, with the type depending on restaurant size and budget.
Kitchen grease exits the hood and soils the exterior wall, how do you protect the facade from grease?
We install external exhaust ducts at proper angles away from the facade if possible, and recommend regular hood and filter cleaning to minimise grease discharge.
Does make-up air from the street bring dust and smells in?
Make-up air can come from inside the building or a dedicated inlet away from the main street, and we fit filters at the air inlet to clean it before entering the restaurant.
