Onida AC Buying Guide: Choosing Between 1 Ton, 1.5 Ton & 2 Ton Models
Indian summers are transforming. And so is the need to look for cooling appliances that cool your room efficiently, irrespective of the extreme and fluctuating weather conditions. Choosing the right AC does not just mean the capacity or going for the larger size for a larger room. It is important to understand that your electricity bill, the speed at which your room is cooled to the desired temperature and the weather conditions that your AC will support, everything depends on the AC you choose. Also, the occupancy of the room and the impact of sunlight on the room should be the determining factors while you are making your buying decision. To make things easier for you and help you buy the right Onida AC for your room, we have a complete buying guide. So, keep reading further, understand what you need and pick the right cooling appliance for your home in 2026.

What Does AC Tonnage Mean?

Whether you are buying an AC for the first time or want to replace your old one, you need to understand what a ton actually means and what it does not. Here is all that you need to know:
  • A "ton" in an AC does not mean its physical weight. Instead, it measures its cooling capacity, precisely, how much heat the AC can remove from a room in one hour
  • 2 air conditioners from the same brand with the same capacity can cool at different rates and in different ways. With 2-way and 4-way cooling mechanisms, you feel the air flow differently in your room
  • A higher tonnage means an increased electricity bill. So, it is important that you pay equal attention to the star rating while buying a new AC for your room to ensure efficient cooling
  • A bigger AC does not always mean better cooling. The cooling depends on the build, the air flow mechanism, the materials used and more

Factors to Consider Before Choosing an Onida AC

  • Room Size
    Primarily, your room size should decide the capacity of the AC that you are picking. Larger rooms and the living room should have an AC of around 2 tons, while the smaller rooms can have something around 1 ton for efficient cooling without much investment or a spike in your electricity bill.

  • Sunlight & Heat Exposure
    If the room size is the same, the floor and the direction of the room's face also matter. West-facing rooms or rooms on the top floor will get heated more when other factors remain constant. So, you should keep the same in mind while deciding on the AC for your room.

  • Number of People & Appliances
    If your room is set to be crowded or it will have multiple appliances that will be running almost throughout the day, you need a higher cooling efficiency. Heat generated from TV, gaming consoles, laptops and other appliances can slow down the cooling process if your AC is not very efficient

  • Usage Duration
    Everyone has different AC preferences. Some want it on for the entire day, while in some rooms, you might need to use your AC occasionally. If you need an AC that has to be used for long hours, make sure that you pick the one that comes with inverter technology for efficient energy consumption
