A well-designed commercial HVAC system is one of the most important investments you can make for your office in Pakistan. It directly affects employee productivity, energy costs, equipment protection, and the impression your premises make on clients and visitors.
At Aircon Services, we have designed and installed HVAC systems for corporate offices including IBM, U-fone, MGI, HUM TV, Pak Qatar Takaful, and the UAE Embassy — ranging from small 10-person offices to large multi-floor corporate headquarters. This guide covers everything you need to know.
What Makes Office HVAC Different from Residential?
Office HVAC design is significantly more complex than residential air conditioning for several reasons:
- Higher heat loads — Computers, servers, lighting, and large numbers of people generate substantial heat that must be accounted for in the cooling load calculation
- Zoning requirements — Different departments (boardrooms, server rooms, open-plan areas) have different temperature and airflow requirements
- Operating hours — Offices typically operate 8–12 hours a day, 5–6 days a week, meaning systems must be reliable and energy-efficient over sustained operation
- Aesthetic integration — Equipment must be integrated neatly into the interior design, particularly for client-facing areas
Choosing the Right System for Your Office
Small Offices (Up to 10 Rooms)
For small offices in Islamabad and Rawalpindi, individual split AC units or a small VRF system with 4–8 indoor units is typically the most cost-effective solution. Inverter split ACs from Gree or Haier in the 1.0–2.0 ton range are common and energy-efficient.
Medium Offices (10–50 Rooms)
A VRF system becomes highly advantageous here. A single outdoor unit connecting to multiple indoor units of different types (wall-mounted, cassette, ceiling concealed) provides individual zone control, centralised monitoring, and superior energy efficiency. This is the system we most commonly specify for mid-size corporate offices in Blue Area and F-7 Islamabad.
Large Office Buildings (50+ Rooms, Multiple Floors)
For large multi-storey office buildings, a central chilled water system with air handling units (AHUs) on each floor provides the best long-term solution. This allows centralised energy management, integration with building management systems (BMS), and consistent comfort across all floors.
Server Room Cooling
Server rooms and data centres require specialised precision air conditioning that maintains temperature and humidity within tight tolerances 24 hours a day, 365 days a year — including during power cuts. We recommend dedicated precision AC units with redundant systems for any IT room.
Estimating Your Office HVAC Budget
As a rough guide for office HVAC installation in Pakistan:
- Small office (5–10 split ACs): Rs. 400,000 – Rs. 800,000
- Medium office VRF system (10–30 indoor units): Rs. 2,000,000 – Rs. 6,000,000
- Large office central plant: Rs. 8,000,000 – Rs. 50,000,000+
