AC Buying Tips

Here are some tips to keep in mind when buying an air conditioner:

Determine the Cooling Capacity

The cooling capacity of an air conditioner is typically measured in British Thermal Units (BTUs) per hour. To determine the AC's cooling capacity, you need to calculate the square foot area of your room to figure out the capacity needed to cool it. Read this AC buying guide to know more.

Room Size

The capacity required to cool a room depends on the size of the room. For example, a one-ton AC is more than sufficient for a small room of 140 sq. ft; the heat load is manageable. However, a 1-ton AC will likely be overloaded in a medium-sized room.

Noise Level

The loud AC can be a nuisance if you have a baby in your room or are a light sleeper. So, remember to check the noise level, particularly for window ACs. Yet in this situation, buying a split air conditioner might be best for you.

Average City Temperature/Weather

The ambient temperature is also essential in determining the type of AC you need. If you live in an area with harsh summers, you may need a 1.5 or 2-ton AC, even for medium-sized rooms.

The Number of Occupants

When buying an air conditioner, consider the number of people in a room, as this adds to the heat load in the room. A crowded room requires a sturdy unit.

Smart Home Compatibility

Smart features in your air conditioner can help you integrate it seamlessly with other smart devices.

Aluminium Coil vs. Copper Coil

Aluminium and copper are common materials used to construct AC (air conditioning) coils. Both have their advantages and disadvantages.

Aluminium Coil: An aluminium coil is made of aluminium and is lighter than copper, making it easier to handle and install. It is also less expensive than copper, making it a more cost-effective option. However, aluminium is more prone to corrosion, leading to leaks and reduced efficiency.

Pros:

1. Lighter and easier to handle and install
2. Less expensive than copper
3. Good heat transfer properties

Cons:

1. It may require special coatings or treatments to prevent corrosion.
2. A lower melting point than copper can be an issue in high-temperature environments.

Copper Coil: Copper is more durable than aluminium and less corrosion prone. It is also a better conductor of heat than aluminium, allowing for faster heat transfer and improved efficiency. However, copper is heavier and more expensive than aluminium, making it a more costly option.

Pros:

1. More durable and less prone to corrosion
2. Better conductor of heat than aluminium, allowing for faster heat transfer and improved efficiency
3. It Can withstand high temperatures without melting or deforming.

Cons:

1. Heavier and more difficult to handle and install
2. More expensive than aluminium
3. It may be more challenging to source and obtain.

Inverter vs. Non-Inverter AC

Inverter ACs and non-inverter ACs have different operating mechanisms, each with advantages and disadvantages.

Non-inverter ACs have a compressor that runs at a fixed speed, which runs at full power until the desired temperature is reached and then shuts off. When the temperature in the room rises above the set level, the compressor starts again at full power. Non-inverter ACs are less expensive but consume more electricity and are less energy efficient.

On the other hand, inverter ACs have a compressor that can vary its speed according to the cooling requirement. It can run at lower speeds to maintain the desired temperature, saving energy. Inverter ACs are more expensive but consume less power and are more energy efficient.

In conclusion, an inverter AC would be the better choice if you are looking for an energy-efficient AC that can save you money on your electricity bills in the long run. However, if you are looking for a more affordable option and don't mind higher energy consumption, a non-inverter AC might be more suitable.

Power consumption (BEE Rating)

It is essential to understand the power consumption of your AC. BEE ratings, now called ISEER ratings, are issued keeping in mind the AC Energy-Efficiency Ratio (EER). ACs are rated in British Thermal Units (BTUs), Regardless of their tonnage or capacity.

Features to Look for When Buying an AC

Wi-Fi compatibility: Wi-Fi air conditioners use your home Wi-Fi connection to connect to the internet. You can control your AC remotely from your smartphone or tablet using the app. If you have multiple Wi-Fi ACs in your home or office, you can easily control them using only a mobile device. Moreover, it provides wireless access to your AC even when you are not at home.

Activity sensors: Activity sensors in air conditioners detect the activity level in a room and adjust the cooling output accordingly to maintain a comfortable temperature. This helps to save energy and improve the efficiency of the AC system.

App control: Replace a conventional remote and gives you more information about the air conditioner and its operations.

Price: At least not long ago, ACs were considered a luxury product. But it has become a highly desired product due to increased demand and global warming. Nowadays, one can easily get a new AC at a responsible price. The price of a 1-ton air conditioner starts from Rs 30,000 to Rs 35,000.

Whereas the range of a 1.5-ton starts from Rs 40,000 to Rs 45,000. Moreover, you can get an AC 2-ton between Rs 50,000 to Rs 55,000. If you prefer an inverter AC, then you should increase your budget a bit more.

Installation Level: The installation level of an AC refers to the level of complexity and expertise required to properly install and maintain the air conditioning system, which can range from basic DIY installation to professional installation by licensed HVAC technicians.

Auto Start: Some ACs do not turn on automatically when the power goes out and then comes back on. ACs with auto start feature can restart themselves once the power comes back on and set the temperature to the level you set before the power outage.

Dehumidification: While all air conditioners control the humidity level while cooling the room, some ACs come with an additional dehumidification function that reduces the humidity in the room. This feature is essential if you live in an area with uncomfortably high humidity.

Four-Way Swing: Most air conditioners have a two-way swing to circulate air in the room. While this may not make a big difference regarding the effectiveness of the AC in cooling the room, it improves the cooling perception as the air passes by you every few seconds. Some ACs come with a four-way swing, which means they can circulate air horizontally and vertically, making it easier to adjust the airflow of the AC more precisely. It is an essential feature if airflow to a particular spot in the room is essential to you.

Sleep Timer: The Sleep Timer in an AC allows you to set a time for the air conditioner to turn off automatically. This helps conserve energy and provides a comfortable sleeping environment without having to manually turn off the AC.

Tips to Ensure Optimal Cooling

Turn off extra heat sources: Lights and appliances add warmth to a room.

Ensure airflow for the AC: If you want precise airflow from your AC, then always keep AC vents away from obstructions like curtains. 

Check for air leaks: These can be around windows, doors, and vents.

Block direct sunlight: Sunlight makes a room hotter and more difficult to cool.

After-sales Service and Additional Warranty

After-sales service refers to the support and assistance a company provides its customers after a product is sold. On the other hand, an additional warranty refers to an extension of the original warranty that covers any defects or malfunctions of a product beyond the standard warranty period. In the case of air conditioners, after-sales service, and additional warranty ensure that customers receive proper maintenance and repair services, as well as replacements or refunds in case of faulty products.
