Best Ceiling Cassette Air Conditioner Reviews in 2024

Air conditioning is one of the prime requirements of any closed space area nowadays, whether it is your home, office, car, or any other confined space where an ample amount of airflow is not available. Therefore, a wide range of air conditioner models are available on the market, each designed for a specific purpose and offering efficient performance.

Many buyers usually prefer ceiling cassette air conditioners for official applications or mass installations. As the name suggests, these air conditioners are installed in the ceiling, preventing loss of space on the wall or the ground. Therefore, these options are also commonly observed in shopping malls. Here are some important aspects of a ceiling cassette air conditioner that makes them an ideal choice.

  • High BTU Rating: The BTU rating or British Thermal Unit rating is a standardized measurement of the overall cooling capacity of an electronic space cooling device, i.e., an air conditioner. The same can be used for space heaters as well. However, in the case of air conditioners, the BTU rating is the amount of heat removed from the space in an hour, whereas it is the reverse of that for a space heater. So in both cases, you should prefer a higher BTU option to get optimal performance.
  • High Coverage Area: The coverage area is also an important aspect of an air conditioner, especially since its overall applicability depends upon it. It is even more crucial to check the approximate coverage area of a ceiling cassette air conditioner as you will probably install a number of these units throughout the floor. So, make sure you choose an option offering a higher coverage area so that your overall expenditure on the units could be reduced.
  • SEER Rating (Higher Efficiency): Lastly, we will talk about an aspect that also deals with your average expenditure on an air conditioner or the running costs to be more precise. If you are going with a ceiling cassette air conditioner that has a high SEER rating, you will find the machine optimal to use in all seasons. It is basically the ratio of the system’s BTU rating with respect to its power consumption.

By considering all of these factors, you can easily get your hands on a highly efficient ceiling cassette air conditioner that will offer you great returns on your investments and a highly comfortable and relaxing environment in your office. However, you will usually notice that ceiling cassette air conditioners are not as easily available on the market as other types of air conditioners. This is because of the limited application range of these units. So, we have decided to prepare you with this short collection of the best ceiling cassette air conditioners that are the most beneficial options on the market right now. We also have a “Buying Guide” for the same right after our top picks where we will discuss some more important information you should know before buying a ceiling cassette air conditioner.

Buying Guide For The Best Ceiling Cassette Air Conditioner

Ceiling cassette air conditioners have been the most popular choice for an air conditioning unit for an office or any professional workplace for a very long time now. And because of that, these units, while being quite expensive, are also very powerful and capable of maintaining the temperature of a densely occupied office space without any problem. These units are also designed to be highly efficient and they usually offer a high SEER and HSPF rating, making them a cost-saving option for the future.

But unfortunately, since the applicability of these units is very limited, you will find it difficult to choose a decent option on the market that checks all the boxes on your requirements list. To help you lead towards the perfect ceiling cassette air conditioner, we have prepared this buying guide for the best ceiling cassette air conditioner. Here, you can find some of the most common qualities of a ceiling cassette air conditioner which play an important role in their functionality.

1. BTU

While browsing space heaters or space coolers, you will come across a certain BTU rating on all of these appliances, which you can refer to when comparing similar models. The BTU rating of any air conditioner is simply a measurement of the cooling capacity of the air conditioner, telling you the amount of heat the conditioner can remove from the space within a certain period.

As you can guess, you must know the overall cooling capacity of the ceiling cassette air conditioner before investing in one to get an idea about its performance and whether it is suitable for your office space. To check that, you can refer to the following table where we are comparing the approximate BTU rating or capacity needed for a particular space to ensure an efficient AC performance.

BTU Rating Approximate Coverage Area
9000 BTU Rating 450 sq. ft.
12000 BTU Rating 600 sq. ft.
18000 BTU Rating 900 sq. ft.
24000 BTU Rating 1200 sq. ft.
30000 BTU Rating 1500 sq. ft.
36000 BTU Rating 1800 sq. ft.

2. AC Tonnage

The tonnage rating of an air conditioner also refers to the cooling capacity of the air conditioner. However, this is a traditional method of calculating the cooling capacity of an AC which is still widely used by a lot of manufacturers. A single ton of an air conditioner is usually equivalent to 12000 BTUs of capacity hourly.

So, if you can’t find the BTU rating on a particular AC model, you can simply check its tonnage and get an idea about the performance of the air conditioner. The tonnage of an AC also affects several other factors such as compatible room size, required insulation, room occupancy, and performance in different seasons.

Usually, a higher tonnage ceiling cassette air conditioner is a great option for office spaces since such places are usually densely occupied. But, if you already have an idea about the expected load on your air conditioner, you can prefer a smaller tonnage AC without a doubt.

3. SEER

The SEER or seasonal energy efficiency ratio of an air conditioner is a special rating provided to air conditioners that deal with the performance variation of an air conditioner throughout the year due to seasonal changes. The SEER rating is calculated by taking a ratio of the cooling output of an air conditioner in a season with the energy consumption of the same system in the same season.

As you can imagine, an air conditioner with a higher SEER rating is usually the better choice as it has more cooling output available for a certain energy consumption. The SEER rating usually falls between 13 to 25 for a general AC model, whereas a higher SEER rating model is usually preferred for mass installations, especially regarding office spaces and workplaces. While these options might be slightly expensive initially, they turn out to be the economically right choice in the long run.

Although, you may not need a high SEER rating on your AC model at all if you don’t observe a drastic difference between different seasons. A lot of offices only use ACs during summer, keeping the unit inactive the rest of the year, which also eliminates the need to check the SEER rating.

4. Noise Level

The noise level also becomes a concerning factor when you are considering an appliance for an official workspace, unlike a home unit. And the same goes for a ceiling cassette air conditioner, and you should carefully take a look at the prescribed noise rating of the ceiling cassette air conditioner before you make the call. Just like any other electrical appliance, the noise rating for a ceiling cassette air conditioner is also represented in the dB unit, where a higher dB rating represents a louder air conditioner.

And as there are a lot of moving parts inside the air conditioning system, there is bound to be some noise coming out of the system, whether it is a powerful option or a compact unit. The same goes for a ceiling cassette air conditioner, even though this system is concealed inside the ceiling. If you want a reference, 30 to 40 dB of noise is basically the ambiance of a quiet library, 70 dB is the noise of the usual activity of a busy office, and 100 dB of noise is the sound of a running motorcycle. Therefore, you would want to have the noise rating of your air conditioner to be as low as possible, ideally between the 40 to 60 dB range.

Ceiling Cassette Air Conditioner – FAQs

1. How Does A Ceiling Cassette AC Work?

Ans: A ceiling cassette air conditioner is a type of ductless mini-split air conditioning system that is designed to be installed in the ceiling of a room or building. It consists of an indoor unit, typically mounted in the ceiling, and an outdoor unit located outside the building. Apart from the construction of the air conditioner, which makes it a highly compact unit, the overall working principle is pretty much the same as other standard ACs.

Also, you can get flexible air distribution with a cassette air conditioner thanks to its adjustable air vents. Another great aspect of choosing a cassette air conditioner for professional workplaces is its high energy efficiency since it usually comes with inverter technology.

3. Do Ceiling Cassette Air Conditioners Need Frequent Maintenance?

Ans: Just like any other type of air conditioner, cassette air conditioners also require frequency maintenance if you wish to keep the system in perfect shape and keep its performance at the optimal level. However, the frequency of maintenance may vary depending on various factors such as the manufacturer’s recommendations, usage patterns, environmental conditions, and overall system condition. Therefore, it’s important to follow the manufacturer’s recommendations for maintenance and also consider the specific environmental conditions and usage patterns of your ceiling cassette AC when determining the appropriate maintenance frequency.
