Cassette Ac Buying Guide

Choosing the Right Cassette AC

Cassette air conditioners are popular choices for commercial spaces and large rooms due to their efficient cooling, uniform airflow, and discreet installation. When purchasing a cassette AC, consider the following points to make an informed decision:


The cooling capacity of an AC, measured in tonnage, determines how effectively it can cool a space. The capacity needed depends on the room size:

1 Ton AC’s

Suitable for small to medium-sized rooms or areas up to approximately 120 to 150 square feet

1.5 Tons AC’s

Ideal for medium-sized rooms or areas ranging from approximately 150 to 220 square feet.

2 Tons AC’s

Recommended for larger rooms or areas between approximately 220 to 300 square feet.

Power Consumption

Energy Efficiency: Look for models with high star ratings to ensure lower power consumption and reduced electricity bills.

Higher star ratings indicate better energy efficiency, ranging from 1 to 5 stars.

Check the power consumption in Watts to estimate operating costs

Power consumption varies based on the capacity and efficiency of the cassette AC.

Calculating the power consumption of your Cassette AC

1 Ton

1,000 to 1,200 Watts

1.5 Tons

1,500 to 1,800 Watts

2 Tons

2,000 to 2,400 Watts

3 Ton

3500 to 4000 watts

4 Ton

4500 to 5500 watts

kW Rating of the AC

Average number of AC running hours per day
Cost of electricity per unit
Units per month = (kW of AC) * (Daily running hours) * (Number of Days in Month)

Compressor Type

Cassette AC’s may feature different compressor types, each offering unique advantages

Scroll Compressors
Commonly used for their quiet operation and energy efficiency.
Rotary Compressors
Known for their reliability and smooth operation.
Inverter Compressors
Offer variable-speed operation for enhanced energy savings and precise temperature control.

Outline Pipe and Insulation

Refrigerant Lines: Ensure proper sizing and insulation of outline pipes connecting the indoor and outdoor units.

Copper pipes are commonly used for their durability and thermal conductivity.
Proper insulation prevents heat exchange and condensation, maximizing efficiency.

Why should choose? and Avoid a cassette AC


360-Degree Air Distribution
Cassette AC's are designed to provide uniform cooling throughout the room with their unique ceiling-mounted configuration. They distribute air in all directions, ensuring consistent comfort levels.
Space-saving Design
Cassette AC's are installed flush with the ceiling, saving valuable floor space. This makes them ideal for rooms with limited wall space or where aesthetics are a priority.
Large Coverage Area
Cassette AC's are suitable for cooling larger areas or open-plan spaces due to their high airflow capacity and 360-degree air distribution. They can effectively cool rooms with high ceilings or irregular layouts.
Quiet Operation
Cassette AC's are known for their quiet operation. The indoor unit is located in the ceiling, away from occupants' ears, reducing noise levels and providing a more comfortable environment.


Installation Complexity
Installing a cassette AC requires cutting a hole in the ceiling, which can be a complex and labor-intensive process. Professional installation is recommended, adding to the initial cost.
Limited Ceiling Space
Cassette AC's may not be suitable for rooms with low ceilings or limited space above the ceiling. The height of the ceiling and the presence of obstructions can impact airflow and efficiency.
Difficulty in Maintenance
While cassette AC's have lower maintenance requirements, accessing and servicing the unit mounted in the ceiling can be challenging. Routine maintenance tasks may require specialized equipment and trained technicians.
Higher Cost
Cassette AC's tend to be more expensive than other types of air conditioners, including wall-mounted split systems. The cost of installation, ceiling modifications, and maintenance can further increase the overall investment.

Key Differences


Cassette AC’s require ceiling-mounted installation, which can be complex and may require modifications to the ceiling structure. In contrast, other types of AC’s like wall-mounted splits are easier to install and more versatile in placement options.

Air Distribution

Cassette AC’s provide 360-degree airflow, ensuring uniform cooling throughout the room. Wall-mounted splits, on the other hand, have directional airflow and may not reach all areas of the room evenly.


Cassette AC’s are generally more expensive than wall-mounted splits due to their complex installation and larger coverage area. The initial investment and ongoing maintenance costs should be considered when choosing between the two.


Cassette AC’s offer a sleek and unobtrusive design, blending seamlessly with the ceiling and providing a minimalist appearance. Wall-mounted splits are more visible and may affect the room’s aesthetics.
