HVAC

It depends mainly on the size of the cooling load, the hours the office runs and what the building already provides. VRF usually suits small and mid-sized offices and floors with many zones, because each area is controlled separately and no central plant room is needed. Chilled water tends to suit large, high-load buildings, or buildings where the landlord already supplies chilled water. We compare both on purchase cost, running cost and space before recommending one. Read our full comparison.

The main drivers are the heat load (floor area, number of people, equipment and sun-facing glass), the type of system, the length of piping and ducting, fresh air and filtration needs, controls, and how easy the ceiling is to work in. We quote only after a heat load calculation, so you do not pay for oversized equipment.

Yes. Many commercial buildings in Delhi NCR provide chilled water or a base air conditioning installation. We survey what is there, check its capacity against your new layout, and extend or rework the fan coil units, air handling units, ducting, diffusers and controls instead of replacing equipment that still has useful life.

Standards such as the National Building Code of India and ASHRAE 62.1 set minimum outdoor air rates based on the number of people and the floor area. We design to these standards and, where outdoor air quality in NCR calls for it, add higher-grade filtration so the fresh air coming in is also clean air.

For upgrades and partial works, usually yes. We phase ceiling and noisy work, schedule it out of hours where needed, and isolate the areas being worked on. A full new installation is normally done alongside the interior fit-out, before the office is occupied.

Testing, adjusting and balancing reports, commissioning records, as-built drawings, operation and maintenance manuals, equipment warranty documents and a walkthrough so your facility team knows how to run the system.
