Split AC or Window AC? Which is the Best one for your Home?

That was a small introduction about the two, but we know you can’t decide on the basis of that. Here are a few factors you need to consider before you compare the two and decide which one should be an ideal choice for your home.

Consumption of Energy

The consumption of energy depends upon the star rating of the product. The Bureau of Energy Efficiency (BEE) has made it mandatory for all electronics to have a star rating which can range from 1 to 5 star. High energy rating means the appliance consumes less amount of energy. A 5 star ac will definitely consume less power as compared to a 3 star ac. Compared to a non inverter ac, an inverter ac is more energy efficient. A new air conditioner is always more energy efficient as compared to an old air conditioner. If we compare a window ac with a split ac on this criteria, we would say a split ac is more energy efficient.

Space Factor

Space is a major constraint for most of us. A window ac has a single component. It requires a large opening for the installation. This can be a challenge. A split AC is a multiple unit appliance which will have an indoor as well as outdoor unit. The outdoor unit needs a dedicated place but it does not require a large opening. The wire and pipes can pass through the walls easily.

Talking about the noise factor, a split has is capable of either little or no noise. The operation is so silent that you may not even realize the air conditioner is on. However, this is not the situation with a window ac. A window ac can be really noisy and this is because of the compressor.

Cooling Capacity

The cooling capacity of an air conditioner depends upon its tonnage. Split acs are available with high tonnage as compared to a window ac. A split ac is mounted high on the wall and is thoughtfully designed for big size rooms. A window ac is designed for a small sized room. So it’s quite clear the cooling capacity of a split sc is more than a window ac.

Capacity of the AC is dependent on the tonnage of the AC. You will need a higher tonnage air conditioner for the following reasons.

  • If your room size is big you will require a high-capacity air conditioner.
  • Let’s get a little technical- A human body emits heat. If the room has more people, more heat is generated in the room. In this case, you need a high-capacity AC.
  • If you have more furniture in the room you will need a high-capacity ac.

In these situations, a 2-ton split ac will not fail to disappoint you.
