Restaurant & cafe HVAC
Restaurant & cafe HVAC in Al Ajawid
In Al Ajawid, south Jeddah, restaurants and cafés serve large daily crowds in diverse modern buildings. Their HVAC must perform at high capacity to handle intense thermal load and persistent coastal humidity.
- 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 Ajawid is a busy, densely commercial and residential zone where restaurants run under high pressure with heavy thermal load all day. Temperatures and coastal humidity are extreme here, so the HVAC must be very powerful and built for unbroken operation. Coils and filters face relentless heat and moisture stress, and outdoor condensers need excellent airflow and sea-salt protection, since salt hastens corrosion. We need high-capacity central systems with intense regular servicing to keep them running without pause.
Al Ajawid lies in south Jeddah with high residential and commercial density, a modern zone near the waterfront and main roads.
Most large busy restaurants in Al Ajawid run dual or multiple-condenser central AC, with very powerful kitchen hoods under heavy daily use.
The AC setup in Al Ajawid
- 1
Central system with dual or multi-condenser units for load sharing
Splitting load between dual or multiple condensers eases stress on each unit and boosts system efficiency under extreme heat and humidity.
- 2
Ultra-powerful kitchen hood with corrosion-proof ducting
Salt-resistant ductwork keeps hood power steady and stops moisture and odour seeping along long runs.
- 3
High-efficiency filters with built-in moisture separator
Strong filters and built-in separators stop excess moisture entering main coils and greatly reduce mould growth.
Before the visit
Before our visit in Al Ajawid
- 1
Confirm expected system load during peak service
Ask the restaurant owner about guest count, peak hours, and number of ovens and fans in use so we pick the right system capacity.
- 2
Locate outdoor units with salt-spray protection in mind
Position each outdoor unit away from direct sea spray with high airflow, and prepare space for regular servicing and weekly cleaning.
- 3
Schedule monthly maintenance before installation
Agree a monthly or fortnightly maintenance schedule before starting, fixing dates and times that do not disrupt daily restaurant 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.
The restaurant is slammed all day; can the system handle continuous use?
We pick units rated for continuous, heavy-duty operation, fit dual or multi-condenser systems to split the load, and arrange intensive monthly servicing contracts to ensure non-stop performance.
Sea salt and humidity speed corrosion of outdoor units; how do you protect them?
We position outdoor units in high-airflow spots away from direct spray, coat frames with salt-guard paint, and step up corrosion checks to monthly instead of quarterly.
The kitchen hood runs during all service hours; do filters need frequent replacement?
Yes, heavy use and coastal humidity clog filters fast, so we recommend monthly or fortnightly replacement depending on restaurant size, plus weekly coil checks.
Is quarterly servicing enough or do you need more?
No, large busy restaurants in Al Ajawid need monthly or fortnightly service, with duct cleaning every two months and weekly coil and filter inspections.
