Unique HVAC Challenges Restaurants Face in Goa
Restaurants combine two very different thermal environments, a kitchen generating intense heat and moisture, and a dining area where guests expect cool, odour-free comfort. Managing the pressure differential between these zones so kitchen smells and heat do not migrate into the dining area is the central HVAC challenge.
Goa adds extra complexity: monsoon humidity from open-air sections, salt-laden coastal air near beach restaurants, and the dramatic occupancy swings between peak tourist season and the post-monsoon shoulder months.
- Kitchen exhausts significant heat and moisture, dining area AC must be sized to compensate for migration
- Negative pressure in the kitchen (relative to dining) keeps cooking smells contained
- Beach and coastal restaurants face aggressive corrosion on all exposed HVAC equipment
Getting Kitchen Ventilation Right
Kitchen ventilation is not just about comfort, it is a fire safety and health code requirement. A commercial kitchen hood must capture all cooking effluent and exhaust it outside the building. The makeup air system that replaces exhausted air determines whether the kitchen is comfortable for staff and whether negative pressure is maintained.
- Exhaust hood must be sized to the cooking equipment below, typically 50–60 CFM per linear foot of cooking surface
- Makeup air should be introduced at ceiling level, slightly conditioned in Goa to avoid overwhelming the exhaust system
- Grease filters must be cleaned weekly, fire risk and reduced airflow otherwise
- Ensure the exhaust outlet discharges away from AC outdoor unit intakes
Dining Area Comfort and Humidity Control
Restaurant guests in Goa spend 60–120 minutes at the table. During monsoon, maintaining low humidity in the dining area while adjacent outdoor areas are at 90% RH requires careful system design. Oversized AC units short-cycle and fail to dehumidify adequately, correctly sized units that run longer do a far better job of moisture removal.
- Size dining area AC for dehumidification capacity, not just cooling capacity
- Cassette units give even air distribution across tables, avoids cold spots near the unit and warm spots at the far end
- If you have open-to-sky or semi-outdoor areas, design the HVAC boundary carefully
Choosing the Right System for Your Goa Restaurant
For a restaurant under 1,500 sq ft, a combination of cassette ACs in the dining area and a separate exhaust system for the kitchen is usually the most practical solution. Larger restaurants, or those with multiple dining zones, benefit from a ducted or VRF system that allows zone-by-zone control as occupancy varies through the day.
- Small restaurants: 2–3 cassette ACs in dining area, commercial hood and exhaust in kitchen
- Mid-size restaurants: VRF with separate kitchen exhaust, easier management, better efficiency
- Large restaurants: ducted HVAC with heat recovery ventilation and dedicated kitchen ventilation system

How often should restaurant HVAC be serviced in Goa?
Monthly for kitchen exhaust filters (fire safety requirement), quarterly for AC coil cleaning in the dining area, and biannual full service before summer and monsoon. Coastal restaurants may need more frequent outdoor unit cleaning due to salt accumulation. Contact Aermac to set up a restaurant-specific AMC.
