Restaurant & cafe HVAC in Al Muhammar
In Al Muhammar, east Jeddah, restaurants from small to medium-sized need HVAC that combines strong fume extraction with guest comfort. We design a solution fitting multiple zones and different floors.
- Pressure balance
- Make-up air
- Coil protection

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
- 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 Muhammar has medium and high-rise residential buildings with shops and restaurants in the lower floors. Some restaurants span multiple floors or zones with more than one cooker and kitchen, complicating ventilation design. Mixed layouts and uneven spaces require careful study to route ducts efficiently and balance pressure across all areas. A central system may be necessary here instead of separate units.
Al Muhammar is an east-side built-up district of mixed-height residential buildings with multi-storey and multi-zone restaurants.
Several relatively larger Al Muhammar restaurants need powerful central systems with multiple extraction units to cover more than one floor or cooking zone.
The AC setup in Al Muhammar
- 1
Central extraction for multiple zones
A powerful main extraction unit connected to branches for each floor or cooking zone, gathering fumes and venting them from a single external point.
- 2
Grease filters on each branch
Each separate branch has its own grease filter, easing cleaning and maintenance for each cooking zone independently.
- 3
Central or semi-central cooling for thermal balance
Central or large semi-central cooling systems deliver even temperature control across floors and zones without hot and cold spots.
Before the visit
Before our visit in Al Muhammar

Bring full restaurant plans with dimensions
Send us architectural drawings showing each floor, kitchen and zones so the team can do precise design work before the site visit.
- 2
Identify external vent route and constraints
Tell us where air can vent outside and any architectural or regulatory constraints on vent openings.

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.
Our restaurant spans two floors, can one system cover both?
Yes, we design a central system with a powerful extraction unit and branches for each floor, with grease filters on each line and a shared discharge, but it needs careful mapping of space and loads.
The street is tight and rear access is easier, how do we coordinate?
Tell us the best entry point and parking, and we will take measurements beforehand to confirm equipment fits through the rear access safely.
East-side humidity and grease build-up happen fast, how do you cut cleaning frequency?
We fit high-capacity filters and improved drainage, and in larger restaurants may add an extra grease treatment unit to extend intervals between maintenance visits.
Do high ceilings in the ground floor cause extraction problems?
They may present challenges, but we choose extraction units with adequate power and size ducts at the right diameter to maintain correct air velocity without performance loss.
