Whether you're fitting out a 2,000 sq ft retail outlet in Blue Area or a 40,000 sq ft corporate office in Bahria Town, your HVAC system will be the single largest line item on your MEP budget β and the single biggest driver of your monthly running costs for the next 15 years.
Step 1 β Get a proper heat-load calculation
Walk away from any contractor who quotes tonnage based on square footage alone. A real calculation considers occupancy, lighting load, IT equipment, glazing area and orientation, insulation, ventilation rates, and altitude.
Step 2 β Pick the right system topology
Under 5 tons total: light-commercial split or cassette units. 5β25 tons: VRF or ducted splits. 25+ tons: VRF or chilled-water with AHUs.
Indicative pricing in 2025
Light-commercial split installation: Rs 90,000β140,000 per ton turnkey. VRF system installation: Rs 180,000β280,000 per ton turnkey including refnet, controls, and commissioning.
