1 Ton vs 1.5 Ton AC Electricity Consumption: As the heat increases, one question is heard the most in every household, should one buy 1 ton AC or 1.5 ton? Most people believe that bigger AC means higher electricity bill, but the truth is a little different. Taking decisions based only on tones can sometimes prove to be wrong. The real thing is that the power consumption of AC depends not only on its capacity but also on the size of the room, method of use and star rating. Choosing the wrong type of AC not only increases the electricity bill but the cooling is also not satisfactory. If you are also thinking of buying a new AC, then it is important to understand what is the real difference between 1 ton and 1.5 ton AC.

What does 'ton' mean in AC?

Many people think that ton in AC means weight, but it is not so. Here ton means cooling capacity.

• 1 Ton AC≈12000 BTU/hour1 Ton AC≈12000 BTU/hour
• 1.5 Ton AC≈18000 BTU/hour1.5 Ton AC≈18000 BTU/hour

This means that a 1.5 ton AC can cool a large room faster. Whereas 1 ton AC is considered better for small rooms. If a 1.5 ton AC is installed in a small room, it will provide excessive cooling and power consumption may increase. On the other hand, installing 1 ton AC in a big room will put more load on the machine and the bill may also increase.

How much electricity does 1 ton AC consume?

1 ton AC is generally considered suitable for a room of 80 to 100 square feet. Average power consumption: 0.8 to 1.2 units/hour0.8 to 1.2 units/hour

If the AC has inverter technology, then it uses more or less electricity as per the need. A 1 ton AC installed in the right room can prove to be quite economical. But if it is operated in a large room, it will continuously work at high load and may increase the electricity bill.

How much electricity does 1.5 ton AC consume?

1.5 ton AC is generally considered better for rooms of 120 to 150 square feet.

Average power consumption: 1.2 to 1.8 units/hour1.2 to 1.8 units/hour

It draws more power than a 1 ton AC, but that doesn't always mean higher electricity bills. If used in the right room, it can automatically save electricity by cooling quickly. If installed in a small room, it may lead to excessive electricity consumption.

Which AC actually consumes more electricity?

The simple answer is that because of the larger capacity of a 1.5 ton AC, it can draw more power. But the real difference depends on the usage. If the right AC is chosen according to the room, then even a 1.5 ton AC can sometimes consume as much or less electricity as 1 ton. Whereas wrong size AC always causes loss. Therefore, it is not entirely correct to just assume that “big AC will give higher bills”.

Easy ways to save electricity

If you want to keep your AC bill low, some simple habits can help a lot. First of all, keep the temperature between 24 to 26 degrees. Running AC at very low temperatures increases power consumption rapidly. Keep doors and windows closed so that cold air does not go out. Regular servicing and cleaning of filters is also important. Inverter AC proves to be a better option in the long run as it adjusts itself as per the need.

What to keep in mind before buying?

While buying an AC, do not focus only on the price or ton. The size of the room, direction of sunlight, insulation of the walls, number of people in the house and usage time, all these things decide which AC will be right for you. Choosing the right type of AC is the biggest power saving. That means the decision is easy, choose the right AC and not just a big AC. This will save your pocket and also provide relief from the heat.
