Buying guide for best 1.5 ton split AC in India

Buying Guide to get the best 1.5 ton Split AC for your home

When choosing a 1.5 ton AC, you need to think about the vital decision-making factors such as energy efficiency, power consumption, compatibility, noise level, etc. Being a costly investment, you must choose an air conditioner wisely.

1. Compatibility of 1.5 ton capacity with room size

The first thing you need to see is the room size in which you want to install the AC. The capacities of the air conditioners are classified as per the tonnage. Choosing the wrong tonnage of air conditioner will increase energy consumption and decrease the product’s life span.

The tonnage of the air conditioner is directly proportional to BTU (British Thermal Units). It stands for the amount of heat that can be eliminated from the space by the AC. 12000 BTU AC capacity is suitable for a room of 110 sq. ft. area. On the other hand, a room of 300 sq. ft. area will require a split AC with a capacity of 24,000 BTUs. 

AC Tonnage Capacity vs. Room Size

1.5 ton split air conditioners are best suitable for a room size up to 250 sq. ft. In comparison, 1 ton and 2 tons capacities are ideal for up to 150 and 400 sq. ft. area. Sometimes you will also need to install multiple air conditioners if the room has an area of above 400 sq. ft.

Capacity of AC compared to room size

The following calculator can help you choosing an ideal capacity of an air conditioner according to the room size.

2. Electricity Consumption of 1.5 ton AC

When choosing the best 1.5 ton split AC, we have to ensure that it doesn’t cause a massive spike in our electricity bills. This is always a thought that haunts Indians when they decide to buy an air conditioner. It is already known that an AC with a larger capacity will consume more energy than a lesser capacity.

But if you end up buying an AC that doesn’t meet the minimum requirement for the needed space, it may also consume more electricity. Purchasing an air conditioner after considering the energy efficiency and power consumption is crucial. Use this calculator to compute the electricity usage by an AC.

Along with that, you can find inverter ACs, which make the device more energy efficient. The energy efficiency of an air conditioner is the ratio of cooling capacity to the input power. Thus, with an increase in the cooling capacity and decrease in the input power, the efficiency of an AC increases resulting in low power consumption.

annual energy consumption of the best 1.5 ton split AC

In the end, the electricity consumed by your AC will depend on your frequency of usage. If you use the air conditioner regularly for more than 8 hours, then you are bound to pay more for it.

You can reduce power consumption such as keeping the filter clean. Use a ceiling fan along with the air conditioner for better air circulation.

3. Energy Efficiency Ratings

ISEER energy rating of AC

Along with the features of the device, you must also focus on the energy ratings. These ratings include the BEE star rating, EER (Energy Efficiency Rating), ISEER (Indian Seasonal Energy Efficiency Ratio). The Bureau of Energy Efficiency (BEE) has enforced specific guidelines for the rating systems. All the products we have listed comply with these guidelines.

BEE Star Rating for 1.5 Ton ACAnnual Power Consumption (Approx.)
1 Star1245 kWh
2 Star1185 kWh
3 Star1100-1235 kWh
4 Star945 kWh
5 Star840-1130 kWh

The BEE star rating and ISEER rating are essential to choosing an energy-efficient AC with a high cooling capacity. You will find these ratings on a sticker present in front of your air conditioner. Watch the following video for a clear idea about these ratings.

COP (Coefficient of Performance) is another critical measure to find an AC’s energy efficiency. An AC with a high COP will have a less operating cost. Knowing the EER, ISEER, and COP of air conditioners is crucial to determine the energy efficiency.

4. Refrigerants used in the best 1.5 Ton Split AC

Almost all of us have heard that CFC or Chlorofluorocarbon is a refrigerant that shouldn’t be used. It has been mandatory that companies need to stop using CFCs in their air conditioners. People who are using air conditioners with CFC refrigerants must upgrade to be more eco-friendly ACs.

In comparison, HFCs are safer for the environment. Among them, R32 is most used in the best 1.5 ton split ACs in India. They do not cause any damage to the ozone layer as they have zero ODP (Ozone Depletion Potential). GWP or Global Warming Potential is another critical term used to determine refrigerants’ impact on the environment.

Refrigerant for 1.5 Ton ACODPGWP

Among all the refrigerants used in 1.5 ton split air conditioners, R32 has the lowest GWP. For this reason, choose an AC with R32 refrigerant. As an alternative, you can select R134a or R410a with a slightly high GWP. Thus, make sure to check the refrigerant of the air conditioner before purchasing it.

5. Plan for Installation before you buy

Most customer cares, and third-party service centers charge for installation beyond the cost of air conditioners. Usually, the cost of installation ranges from Rs. 400 to Rs. 2000 depending on the scope and requirement. You may need to make space in your window, or you may need to make a small hole to accommodate a Split AC.

Frequently Asked Questions about air conditioners

Which air conditioner is best for home use in India?

LG 1.5 Ton 5 Star Inverter Split AC is the best 1.5 ton AC for home use in India. Alternatively, try Panasonic 1.5 Ton 5 Star Wi-Fi Twin Inverter Split AC or Whirlpool 1.5 Ton 5 Star Inverter Split AC. Just check your requirements and get an AC according to your needs.

How does an air conditioner work?

An air conditioner works on the refrigeration cycle. In this process, there are four significant components through which the refrigerant passes-compressor, condenser, expansion valve, and evaporator. The first one is the compressor that pushes the refrigerant (high-pressure vapor state) into the condenser, condensing to a high-pressure liquid state. Here, the heat from the refrigerant is transferred to the ambient air. After that, the refrigerant expands through the expansion valve to form a low-pressure mixture of liquid and vapor. Next, it passes through the evaporator, where the heat of the air is transferred to the refrigerant. In this process, the temperature of the refrigerant increases, and the room air decreases. Finally, it flows to the compressor again as a low-pressure vapor and completes the refrigeration cycle. In 1.5 ton split air conditioners, the condenser is present inside the outdoor unit, and the evaporator is placed inside the indoor unit.the refrigeration cycle

Are air conditioner covers a good idea?

If you mainly use the air conditioner during hot seasons, then it is a good idea to cover your split AC in the inoperative months. It can be beneficial for both the indoor and outdoor units of your AC as they will be safe from dust, rain, snow, and debris. If you want to use such a cover, ensure to remove it during the operative months to make the AC function properly.

Can an air conditioner make you sick?

People often believe that being inside the cold environment of the air conditioner can make them sick. In reality, frequent changes in temperature (from AC to non-AC and vice versa) can make you sick. The problems may arise because of the airborne virus and bacteria. This is one of the reasons that you need to clean the AC filter. Also, make sure to block any water leakage to prevent the growth of mold and mildew.

Can an air conditioner be used as an air purifier?

Thus, an air conditioner is not a suitable alternative to an air purifier. It will be best if you get it separately.

So, anytime you hear such a noise, it is better to call a professional who can help get rid of the problem.
