SITC of Air Conditioning System
(Supply, Installation, Testing & Commissioning)
SITC of an Air Conditioning System refers to the complete responsibility of delivering a fully functional, performance-verified AC system—from supplying approved equipment to final commissioning and handover.
It is the most preferred scope in commercial, institutional, healthcare, hospitality, and industrial projects because it ensures single-point accountability and reliable system performance.
1️⃣ Supply (S)
Supply includes procurement and delivery of all approved air conditioning equipment and materials as per consultant BOQ and specifications:
-
Air conditioning systems (DX, VRF/VRV, Chilled Water, Package Units)
-
Indoor units (AHUs, FCUs, Cassette, Ducted units)
-
Outdoor units / Chillers / Condensing units
-
Ducting, piping, insulation, valves, dampers
-
Electrical panels, controls, sensors
-
Accessories and consumables
Key Focus:
Correct capacity, approved makes, accessories completeness, and safe storage at site.
2️⃣ Installation (I)
Installation is the most critical phase where design intent is converted into actual performance.
Equipment Installation
-
Proper placement and alignment of indoor & outdoor units
-
Adequate service and maintenance clearances
-
Vibration isolation and noise control measures
Ducting Works (if applicable)
-
Fabrication as per approved drawings
-
Airtight joints and proper supports
-
Thermal insulation as per specification
Piping Works
-
Refrigerant / chilled water piping with correct sizing
-
Welding / brazing as per standards
-
Pressure testing before insulation
-
Vapor-barrier insulation to avoid condensation
Electrical & Controls
-
Power cabling and earthing
-
Control wiring and interlocks

Pressure testing of refrigerant / water piping
-
Vacuuming and dehydration (for DX/VRF systems)
-
Electrical insulation and continuity tests
-
Pre-start checks of compressors, fans, pumps
-
Verification of safety devices and interlocks
4️⃣ Commissioning (C)
Commissioning confirms that the air conditioning system performs as designed:
