A complete guide to choosing inverter split AC of right capacity for your space

Staying cool and comfortable all year round is not a luxury; it is a necessity for an elevated lifestyle, and choosing the best AC for your space is not just about grabbing an excellent deal. It involves selecting the best brand, the ideal type of AC, and most importantly, the correct capacity of AC to suit your cooling needs.

This blog by Onida is a comprehensive guide to choosing the right capacity of inverter split AC (the most trending and the most upgraded AC in the market today) for your dear space. Whether it is a compact bedroom, a comfortable studio apartment, a luxurious living room, or a decent-sized office, Onida has a solution for every air conditioning requirement.

Understanding ‘Inverter split AC’

As the word ‘split’ suggests, an inverter split AC comprises two separate units - an indoor unit which is mounted inside a room for air circulation, and an outdoor unit, installed outside, housing the compressor and condenser. It uses the inverter technology that operates with pulse-width modulation (PWM) required to regulate the speed of the compressor motor, adjusting the cooling output dynamically based on your room’s needs. Rather than turning off once the desired temperature is reached, the compressor slows down, maintaining a steady climate unlike in non-inverter ACs that operate in a fixed on/off mode. Key differences between an inverter AC and a non-inverter AC may be summed up as under:

Inverter AC features: Variable speed, continuous operation, smooth temperature regulation, reduced energy consumption.

Non-inverter AC features: Fixed-speed, and frequent on / off cycles resulting in power spikes and temperature swings.

In short, inverter ACs are smarter, quieter, and more economical (ideal for Indian households with extended AC usage).

Benefits of inverter split ACs explained pointwise

• Energy Efficiency: Inverter ACs consume up to 30–50% less electricity than traditional air conditioning systems. Significant savings on your energy bills, isn’t it?
• Silent Operation: Onida’s inverter AC ensures almost zero noise levels due to the use of inverter technology, making it perfect for light sleepers and ideal workspaces.
• Faster cooling and consistent temperature maintenance: Frequent fluctuations have no scope in Onida inverter split ACs, and the desired temperature is achieved in no time after switching the AC on.
• Environment friendliness: Onida AC exhibits excellent care for the planet by using next generation coolants that leave a minimum carbon footprint while offering perfect comfort inside the room.
• Durability along with minimum maintenance: Steady operation of the compressor (without frequent on/off) ensures least wear and tear, extending its shelf life and guaranteeing low maintenance costs.

Choosing the right category (type) of AC is not enough to enjoy the best results; going for the right capacity of Inverter Split AC is equally important to have a relaxing experience inside a space.

Here’s a detailed guide to help you pick the right-sized Onida Inverter Split AC to suit your cooling requirements.

Measure Your Room Size (capacity recommended for sq.ft)

• 2 tons for a Large size room (170-180 sq.ft.)
• 1.5 tons for a Mid size room (120-180 sq.ft.)
• 1 ton for a small size room (50-120 sq.ft.)

(Tip: Multiply your room’s length × width to calculate square footage)

Room size should not be the sole determinant of inverter split AC’s capacity for a space, other factors that need consideration are as follows:

Room Characteristics

• Ceiling Height: If your ceiling is higher than 9–10 feet, increase capacity by 0.2–0.5 ton.
• Sunlight Exposure: Rooms receiving direct sunlight (like west or south-facing rooms or top-floor rooms) may need a higher capacity AC—add 0.2 – 0.3 ton.
• Occupancy: If more than 2–3 people regularly occupy the space, add 0.1 ton per extra person.
• Heat-Producing Appliances: Rooms with TVs, computers, or kitchen appliances generally need additional cooling power.
• Insulation Quality: Poor insulation means your room loses cool air faster—opt for a higher capacity if this is the case.

Climatic conditions of a region

Spaces in hot and humid climatic zones such as Mumbai, Chennai, or Delhi need to be fitted with AC of slightly higher capacities as compared to places that have cooler climates or are based on higher-altitudes.
