Which Kind Of Air Conditioner Is Best For Your Space?


Selecting the right air conditioner is crucial, as there are three main types: Split AC, Window AC, and Portable AC, each with its own advantages and disadvantages.

Split AC:

The inside unit of a split air conditioner (AC) houses the evaporator and blower coils, while the outdoor unit is linked to the indoor unit by pipes that deliver refrigerant.

Split air conditioning systems provide more airflow and quicker cooling; however, they can only be installed inside and outdoors and are costly to remove. In comparison to other AC kinds, they also require more maintenance.

Window AC:

Window air conditioners, often referred to as monoblock ACs, are easier to install and take up less room, which makes them practical for rental homes or those who move frequently. They might not, however, have the same visual attractiveness as split air conditioners.

Window ACs offer advantages but have drawbacks like limiting natural light and ventilation, being noisier than split ACs, and may not be suitable for large rooms.

Choosing the Right AC Size

Effective cooling requires matching the capacity of an air conditioner to the size of the room; for a more precise measurement, the British Thermal Unit (BTU) rating is advised.

The appropriate capacity for an air conditioner depends on factors including square footage, ceiling height, insulation, and sun exposure for best results. The BTU rating quantifies the energy efficiency and cooling speed of the air conditioner.

1 KW/Hr = 3,412 BTU

12,000 BTU = 1 Ton

A room's number of windows, heat-producing equipment, exposure to sunshine, exterior wall and ceiling areas, and person count are some of the variables that affect an air conditioner's cooling performance. The cooling capacity of an air conditioner is mostly dependent on its tonnage and BTU ratings, which offer a broad estimate depending on the dimensions of the room and external conditions. You can use the following chart to determine the appropriate tonnage for your space.

Room SizeBTUTonnage
100-120 sq. ft.6,000 BTU0.5 Ton
120-150 sq. ft.9,000 BTU0.75 Ton
150-180 sq. ft.12,000 BTU1.00 Ton
180-250 sq. ft.18,000 BTU1.50 Ton

Which Is Better, Inverter or Non-Inverter AC?

There are only two different types of AC, inverter and non-inverter. Generally, the inverters are power-saving but more expensive too. Most people believe that an inverter AC is meant to run on a power inverter (power backup) which is absolutely wrong. This is what you will mostly hear from salespersons at some retail shops.

In a non-inverter AC, the compressor works at full power until the temperature inside the room reaches your desired level then it stops. This start-stop process not only puts sudden load on the power supply but also consumes more electricity. On the other hand, the inverter AC’s compressor runs all time and adjusts how much electricity it should consume according to requirement continuously. That’s why they are called so because they can invert their workability depending upon need or demand which makes them better than others when it comes to saving energy However this functionality costs more money as well.

What is a Dual Inverter AC?

Dual-inverter ACs are advanced versions of BLDC motors with twin rotators, creating a 180-degree phase difference. This allows the AC to operate at a wider frequency range, making it more versatile and efficient in cooling.

They give better cooling performance and consume lower energy likened to normal inverter ACs, framing them comfortably and cost-effective. Innovation continues to ameliorate everyday appliances, making them a testament to the power of advanced motor technology.

Does Your AC Need a Voltage Stabiliser?

New ACs often come with built-in voltage stabilizers, protecting them from high and low voltages, ensuring stable power supply and prolonging lifespan. However, these stabilizers have operational limits, which vary depending on the model and brand.

To ensure optimal performance, check the manufacturer's voltage stabilizer ratings. In areas with frequent voltage fluctuations, consider purchasing a more powerful stabilizer for additional protection. Proactive precautions are crucial to safeguard appliances and maintain comfort.

How Crucial Are the Warranty and Service Quality of an AC?

The warranty period and service quality are crucial for expensive appliances like air conditioners (ACs). Most ACs come with a 1-year brand warranty and a longer compressor warranty, with some brands offering as low as three-year warranties and premium brands as high as ten-year warranties.

Regular maintenance is essential for AC efficiency, so an annual maintenance contract (AMC) plan from a trusted service provider is recommended. Onsitego's Comprehensive AMC plan offers up to two years of repair and maintenance support, including two preventive visits, unlimited repairs, free gas charging, and spare parts costs.

The quality of servicing is just as vital as the duration of an air conditioner's warranty. When it comes to customer experience, customer happiness, and service quality, certain brands are superior to others.

Examine reviews on websites, forums, social media, YouTube comments, Quora, online stores, and other sources to determine a brand's level of customer service and satisfaction. Ask friends and acquaintances about their impressions of the AC brand as well.

Other Features to Take Into Account When Purchasing an AC

Auto Start:

The Auto Start feature in an AC is a convenient feature that automatically restarts and restores settings after a power outage, enhancing comfort and maintaining desired temperature settings, providing a seamless experience during unexpected power interruptions.


Dehumidification features in air conditioners( ACs) assist preserve optimal moisture situations, especially in areas with high moisture situations. These features reduce redundant humidity, creating a more comfortable inner atmosphere and reducing earth or mildew growth. ACs naturally reduce moisture during cooling, but devoted modes can help maintain optimal moisture situations more efficiently.
