'Cool Explainer'! Confused between 1.5 ton vs 1 ton ac? Know what it means and why it matters

1.5 Ton and 1 Ton AC Difference: Every business has its own terms and with those terms, comes its own jargons. And, people in that business think that customers have the knowledge of these industry terms and their understanding is enough to come to a decision by themselves.

In this article, let us describe some jargon related to the air conditioner industry that will help you choose the right AC for you.

Have you ever wondered when people talk about air conditioners (ACs), what do they mean by the word "ton"? However, it's not about weight, but cooling power!

Ton: Not weight, actually cooling capacity

A common misconception: "ton" doesn't represent the physical weight of the AC. While going to buy an AC, when the salesperson mentions a "1-ton" or "1.5 ton" AC, s/he is talking about its ability to cool a space. Ton or tonnage refers to the unit used to measure the cooling capacity of the air conditioner based on the size and other features of a room. This capacity is measured in BTUs (British Thermal Units) per hour, commonly denoted as BTU/hr.

Here's the calculation

1 Ton = 12,000 BTUs/hour

This means that the higher the BTU rating, the more powerful the AC.

Why ton/tonnage in AC matters: Finding the right fit

BTU is a standard measuring unit and for every square foot of the room, one will need 20 BTU/hr. Imagine BTUs as tiny heat warriors. You need enough warriors for your room size. So, the bigger the room, the more BTUs (and potentially tons) one will need.

1.5 Ton and1 Ton AC Difference: Confused between 1.5 ton vs 1 ton AC? Know what it means and why it matters
Here's a comparison between 1 ton AC and 1.4 ton AC.

Room size and type

This is the foundation. A 1-ton AC won't suffice for a large living room and a 1.5-ton might be overkill for a bedroom. A 1 ton AC is ideal for a room having 200 sq. ft area while 1.5 ton AC is fit for a room size ranging from 200 to 250 sq. ft. Also, 1 ton AC is ideal for Bedrooms, studio apartments, and smaller offices while 1.5 ton C is fit for master bedrooms, medium-sized offices, large living rooms, and bigger dining halls. 1 ton AC is very efficient for compact cribs while the other one is ideal for spaces that require more cooling.

AC CapacityBTUs per hourIdeal for
1 Ton12000Space up to 200 square feet
1.5-Ton18000Bigger space up to 250 square feet

Energy efficiency

It can be tricky to differentiate between the two AC capacities as they offer things that may differ from one another. 1 to AC usually sips electricity, but lowers power consumption while 1.5 ton AC sips a bit higher electricity and consumes a lot more power than a 1-ton.

Climate

A 1 ton AC is ideal for moderate climates while 1.5 ton AC is better for hotter weather conditions which means 35 degrees Celsius or above.

Annual electricity consumption

Bureau of Energy Efficiency India's data shows the power consumption of both the AC sizes calculated in UNITS or Kwh for 1600 hours.

3 Star Inverter7261077
4 Star Inverter658972
5 Star Non-Inverter7601130
5 Star Inverter557815

Cost

The budget can be a deciding factor that can influence your decision while buying an AC. 1 ton split ACs costs around Rs 35,000 and most window ACs are available Rs 30,000 while 1.5 ton ACs are costly in comparison and a split ACs can reach Rs 50,000 while window ACs are prices start from Rs 30,000.

Noise

A 1 ton AC is mostly quiet, around 25 dB for split ACs and 1.5 ton ACs produce more noise in comparison to a 1-ton around 35dB.
