Restaurant & cafe HVAC
Restaurant & cafe HVAC in Al Harazat
Al Harazat in east Jeddah hosts growing numbers of restaurants and cafes in a modern developing district with diverse building sizes and uses. HVAC here needs careful balancing between kitchen hood and general ventilation while managing both desert dust 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 Harazat is a developing modern district with a mix of residential and commercial buildings of varying sizes and designs, so restaurants and cafes here range from tight shops to larger commercial spaces. Being east of Jeddah, it faces both fine desert dust and sea moisture, doubling the challenge of protecting coils and filters. The design here must balance adequate hood power with dual protection from dust and humidity.
Al Harazat is in east Jeddah, a growing mixed residential and commercial district with diverse buildings hosting a growing number of restaurants and cafes.
Restaurants and cafes here need medium to high-capacity hoods and strong air filters because desert dust mixes with coastal moisture.
The AC setup in Al Harazat
- 1
Central AC with medium-capacity hood
Most units here have medium spaces, so medium-capacity hoods suffice with central AC distributed to dining and corridors.
- 2
Dual high-capacity filters for dust
We fit primary and secondary filters to catch fine desert dust and moisture-mixed particles.
- 3
Drainage with dual protection
We use rust-resistant pipes with strong moisture traps to prevent odour and moisture back-flow in this mixed climate.

Tell us where the supply and drain openings are
We need to know where air supply and drain openings will be so we can design the system to balance hood power with dust protection.
- 2
Measure the kitchen and dining dimensions precisely
Precise kitchen and dining dimensions help us calculate hood power and air supply accurately to achieve the right balance.
- 3
Check the condition of exterior openings and ceilings
Dust enters through small gaps, so ensure openings seal properly and the roof and exterior surfaces are sound to prevent dust or moisture infiltration.

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.
Dust levels here are high; will the filters clog quickly?
Yes, desert dust requires thick, high-capacity filters; we recommend cleaning them monthly or every two months instead of quarterly, and fit a filter-pressure gauge.
We get humidity from the sea and dust from the desert; how do you protect the coils?
We use coils and filters treated to handle dust and humidity, and fit a pre-filter to trap large particles before they reach the coils.
The kitchen is open and space is somewhat tight; how do you balance the pressure?
We design a separate supply that pushes parallel air toward the dining area with a precisely sized kitchen hood, so air does not get pulled from dining toward the kitchen.
Our building's wiring is relatively new; will installation be quick and safe?
Yes, modern wiring provides adequate capacity and better safety, but we still inspect the panel and confirm there are separate circuits available for the hood and AC.
