Are you in the market for an air conditioner? Do you know the differences between a 1 ton and 1.5 ton AC unit? If not, don’t worry—you’re not alone! Many people struggle to understand these two units, so they often end up making expensive mistakes when purchasing one. In this article, we’ll break down all of the differences between a 1 ton and 1.5 ton AC unit so that you can make an informed decision with confidence.

There are several things that set 1 and 1.5 ton ACs apart when it comes to cooling power and energy efficiency ratings. since bigger units require more energy to run effectively, they may cost more upfront as well as on bills over time.

Finally, keep in mind that the number of people living in your house may also play into what type of air conditioning system works best for you; with multiple family members inside, it’s likely that each person generates their own body heat which needs to be taken into account when shopping around for an AC unit! By taking all these factors into consideration, you can find the right model that meets both your budget and cooling requirements

What Is Ton?

A ton, in the context of air conditioners (AC), is a measurement unit used to express cooling power. It defines how much heat an AC can remove from a room per hour and is measured in British Thermal Units (BTU). But what exactly does this mean? To understand it better, let’s explore what a ton actually entails.

1AC ton =12000 BTUs =3516.857 kilocalories/hour or 3.517 megajoules/hour.

In terms of energy, one AC ton is equivalent to the amount of energy required to melt 1 short ton (2000 pounds) of ice over a period of 24 hours; hence, its name ‘ton’. Put simply, one AC ton means the capability of an air conditioner to cool down 2000 lbs worth of ice in 24 hours – making it capable enough for most households and commercial spaces in hot climates.

Which Is Better In Cooling :1ton Or 1.5 Ton?

A to of air conditioning is equal to 12,000 BTUs (British Thermal Units) per hour. 1 Ton ac units can cool up to 400 square feet and are considered more efficient than a 1.5 ton unit for smaller spaces. On the other hand, a 1.5 ton AC unit offers better cooling capacity at 18,000 BTU’s per hour and can cover an area of 600 square feet or more. Therefore, when comparing cooling abilities between a one-ton and a one-and-a-half-ton air conditioner, it is clear that the larger unit provides greater coverage and higher performance in terms of temperature control.

When deciding which size aircon is best suited for your needs, you need to consider two things: how much space will be cooled by each unit and how much power was consumed by each unit. A bigger AC consumes more electricity but also gives off more powerful cooling for larger areas compared to its smaller counterpart. To make the most cost effective decision it would depend on how large an area you have to cool down efficiently with less energy consumption from the AC system itself. If you have a small bedroom then going with a 1 ton might prove to be sufficient enough as opposed to getting something like a 1.5 ton that may not even reach its full potential due to the room being too small for such high powered cooling output. However, if you have a larger living room then investing in a slightly pricier 1.5 ton might be worth it in order to get maximum efficiency out of the setup while keeping energy costs low over time.

How Much Power Was Consumed By 1 Ton And 1.5ton?

The following table compares the power consumption rate for each type of air conditioner:

OperatingLow noise,High speed fan motorHigh noise ,Low speed fan motor

When it comes to energy-efficiency, a ton ac typically has more star rating than its 1.5 ton counterpart due to its smaller size which requires lesser power consumption for optimal performance. As per cooling-efficiency, usually the higher the Energy Efficiency Ratio (EER), the better is the model’s ability to cool effectively while consuming less electricity.

4. Power Consumption

The difference in power consumption between a 1.5 ton AC and a ton AC is simply staggering! Not only does the larger unit use more electricity, but it also tends to have much lower energy efficiency ratings. For those looking to save money on their bills or reduce their environmental impact, choosing a smaller air conditioning system can make all the difference.

1 Ton AC Power Consumption = 3.5 kilo-watt
1.5 Ton AC Power Consumption = 5.2 kilo-watt

EER=(Cooling Capacity)/(Power Consumption)

5. Price

Moving on from the power consumption of ton and 1.5-ton ACs, it’s time to compare their prices. The cost comparison between a ton and 1.5-ton air conditioner largely depends on its brand, model, energy efficiency rating, and cooling capacity.

It is important to note that higher priced models usually come with extra features like inverters for greater energy efficiency as well as dehumidification settings and even advanced Wi-Fi control capabilities.

6. Warrenty

Coincidentally, the difference between a 1.5 ton and two-ton air conditioner can be found in their warranties. Each of these units come with separate warranty coverage terms and conditions that buyers should consider before making an investment. The following table provides a comparison of both AC’s respective warrenty coverage:

7. Coverage Area

The coverage area of a 1ton and 1.5 ton AC is one of the major differences between them. The cooling capacity of a 1ton AC can cover an area up to 120-140 sq ft, while that of the 1.5 ton AC is around 180-215 sq ft. This means that if you have a room size above 150sqft then it’s better to go for a 1.5 ton AC as it will be able to cool much more efficiently than the smaller unit.

Which Room Size Is Suitable For 1ton And 1.5 Ton?

A perfect air conditioner is like a breath of fresh air – it cools our minds and bodies in the most unbearable heat. But how do we choose between 1 ton and 1.5 ton AC based on room size? Let’s look into this further!

To get started, let’s put together a simple table to illustrate the difference in cooling area size for each type of AC:

Ton Capacity RangeCooling Area Size
1 Ton        100-130 sq ft
1.5 Ton     150-180 sq ft

From the above table, it should be clear that 1 ton AC can chill an area up to 130 sq ft whereas 1.5 ton AC can cover up to 180 sq ft. Thus when selecting your air conditioner, you must keep in mind the square footage (sqft) of the room or space you intend to cool down with air conditioning. The bigger the area, higher will be its cooling capacity needs which can only be met by opting for a larger capacity unit such as 1.5 ton AC.

Thing To Consider For An Air Conditioner

Regular maintenance is essential to keep the air conditioner working efficiently. Consider the maintenance requirements of the air conditioner, such as cleaning the filters or coils, and choose one that is easy to maintain.

Making these comparisons helps ensure you select an energy-efficient model with reasonable operational costs and low noise output, thus meeting all your cool comfort needs without compromising on quality or convenience!

Frequently Asked Questions

1. How Often Should I Change The Air Filter In My Ac Unit?

When it comes to your air conditioner, one of the most important things you can do is keep up with regular filter changes. An air filter for an AC unit helps prevent dust and other particles from entering the system, so it’s essential to replace them on a regular basis. Air filters should be changed at least every three months or more often if needed.

2. What Are The Long-Term Maintenance Costs For 1 Ton And 1.5 Ton Acs?

When it comes to long-term maintenance costs for 1 ton and 1.5 ton ACs, there are some important differences that should be taken into consideration. Firstly, the cost of maintenance for a 1 ton AC is typically lower than for a 1.5 ton AC due to its smaller size and fewer components. On the other hand, a 1.5 ton AC will require more frequent servicing in order to keep it running properly, which can lead to higher repair costs over time.

3. What Are The Noise Levels For Each Unit?

A one-ton air conditioner typically operates at around 65 decibels (dB). This is considered loud enough that it could interfere with conversations or disrupt sleep if installed too close to living areas. On the other hand, a 1.5 ton air conditioner usually runs at about 68 dB, which is slightly louder than its 1-ton counterpart. However, most people find them tolerable for indoor use as long as they aren’t placed directly next to bedrooms or living rooms.

4. What Type Of Refrigerant Is Used In Each Unit?

The most common types of refrigerants used in home air-conditioning systems are Freon (R-22) and Puron (R-410A). Generally speaking, R-22 is found in 1 ton or smaller models while larger appliances such as 1.5 ton ACs use Puron due to its higher efficiency rating and environmental friendliness. Furthermore, when choosing an air conditioning unit based on these two factors, it’s also important to note that many newer models utilize hydrofluorocarbons (HFCs), which have been designed for maximum efficiency and less risk of ozone depletion than their predecessors.


In conclusion, when it comes to deciding between a 1 ton and 1.5 ton AC unit for your home or office space, there are several key factors to consider. Energy efficiency and long-term maintenance costs should be taken into account as well as the size of the room you’re cooling.
