How to Buy AC for Office Spaces

Choosing the right AC for an office depends on room size, layout, occupancy, equipment heat and expected usage. Split ACs suit individual cabins and small meeting rooms, while cassette ACs are better for large open-plan offices because they provide four-way airflow. Window ACs can be cost-effective for smaller offices, while tower ACs work well for temporary setups.

• A 1-ton AC generally suits spaces up to 120 sq. ft.
• Add around 0.5 ton when more than five people regularly occupy the room.
• Computers, servers and printers can increase cooling requirements.
• Higher ceilings may require additional cooling capacity.
• A 1.5-ton AC may suit a 200 sq. ft. office, depending on heat load.
• Office ACs can last around 10–12 years with regular maintenance.

You can also buy a new AC on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales.

Choosing the right office AC depends on the room size, number of occupants, heat generated by computers and equipment, and office layout. Split ACs are suitable for cabins and smaller rooms, while cassette ACs can provide wider airflow in larger, open-plan offices. Window ACs can be a practical choice where installation space is limited, while tower ACs offer flexible placement. A 1.5-ton AC may suit a medium-sized office, although the required capacity depends on the room's heat load. Prices vary by type, capacity, energy rating and features, with models starting around Rs. 35,990. Consider energy efficiency, cooling capacity, maintenance requirements and installation costs before buying. Flexible EMI options can also make an office AC purchase easier to manage.

An office AC differs from a home AC mainly in its operating hours, cooling capacity and ability to handle higher occupancy and heat loads.

Choosing the right capacity helps maintain comfortable temperatures without unnecessary electricity consumption.

The right office AC depends on your office size, layout, occupancy and installation requirements.

• Cassette AC: Best for open-plan offices because it distributes air in multiple directions from the ceiling. Noise levels can be around ≤45 dB, with prices starting at approximately Rs. 55,000.
• Split AC for office: Suitable for cabins, meeting rooms and smaller offices. It can operate at around ≤40 dB, with entry prices of approximately Rs. 35,990.
• Tower AC: Useful for offices requiring flexible placement without extensive installation work. Noise levels can reach around ≤50 dB, with prices starting at approximately Rs. 40,000.
• Window AC: Suitable for small offices with an existing window opening. It can produce around ≤50 dB of noise, with entry prices of approximately Rs. 30,000.
• For larger businesses: Consider higher-capacity commercial AC systems when the office has more employees, equipment or larger floor areas.

Consider cooling capacity, energy efficiency, noise levels, installation requirements and running costs before choosing an AC for your business.

Use 1 ton per 100–120 sq. ft. as the base, then adjust the requirement for occupancy, sunlight and heat generated by office equipment.

• Up to 120 sq. ft.: Start with 1 ton of cooling capacity.
• 120–180 sq. ft.: Consider around 1.5 tons, depending on occupancy and heat load.
• 180–240 sq. ft.: A 2-ton AC may be suitable for a typical office.
• 240–300 sq. ft.: Consider around 2.5 tons, particularly for busier workspaces.
• 5+ people: Add around 0.5 ton when more than five people regularly occupy the office.
• Servers or heavy equipment: Add 0.5–1 ton depending on the equipment's heat output and operating hours.
• Direct sunlight: Rooms exposed to strong sunlight may require additional cooling capacity.

How to calculate office AC tonnage

Divide the office area by approximately 100–120 sq. ft. per ton, then add capacity for people and equipment. For example, a 200 sq. ft. office may need around 1.7–2 tons before additional heat-load adjustments.

Choose the best office AC by focusing on cooling capacity, energy efficiency and noise level, while also considering office size, occupancy and equipment heat load.

• Check whether a commercial AC is more suitable for larger offices with longer operating hours.
• Consider inverter models for regular use and potentially lower running costs.
• Ensure installation, servicing and filter cleaning are included in your planning.

For the best office AC, match tonnage to the room, prioritise ISEER ≥5, and choose a model with ≤35 dB noise for a comfortable workplace.

An office AC works through three main components: the compressor, evaporator coil and condenser, which work together to remove heat from the workplace.

• The refrigerant absorbs heat from indoor air as it passes through the evaporator coil, cooling the air before it is circulated back into the office.
• The compressor pressurises the refrigerant and moves it through the system, maintaining the cooling cycle.
• The condenser releases the absorbed heat outside the building and converts the refrigerant back into a liquid.

• The AC's cooling capacity is measured in BTU, helping determine whether it can handle the office's size, occupants and equipment heat load.

  
  

Choosing the right capacity and maintaining these components helps an office AC deliver consistent cooling while managing energy consumption.
