Types of Air Conditioners

Now that we’ve highlighted the top AC brands, let’s dive into the different types of air conditioners available in India.

Window Air Conditioner
Window ACs are the traditional, older type of air conditioner and are known for their power consumption. However, they are becoming less popular as split ACs and other models take over due to their more efficient cooling and installation flexibility.

Portable Air Conditioner
These compact ACs are easy to move around and don’t require major installation adjustments like window ACs. They use hoses to expel hot air from the interior, though they tend to be noisier than other types. Portable ACs are still rare in India, but they offer flexibility and convenience for those who need a mobile cooling solution.

Split ACs are the most common type found in Indian households. With two units—one placed inside and the other outside—split ACs offer quieter operation and easy installation. They are highly popular for their cooling efficiency and ability to blend seamlessly into modern homes.

Best AC (Air Conditioner) Buying Guide

Before you buy the best AC in India, here are some key factors to consider to ensure you make the right decision.

1. Size of the Air Conditioner
Choosing the right size of AC for your room is crucial. If the AC is too small, it will struggle to cool the space efficiently. On the other hand, an oversized AC can cause the system to short-cycle, affecting performance. Finding the right balance ensures optimal cooling and efficiency.

2. Star Ratings – What Do They Mean?
ACs come with star ratings from the Bureau of Energy Efficiency (BEE) and ISEER (Indian Seasonal Energy Efficiency Ratio). The higher the star rating, the more energy-efficient the unit is. This results in lower monthly utility bills and better performance over time.

3. Position of Your Room in the Building
The effectiveness of an AC depends on the position of your room. For instance, an AC that works well on the top floor might struggle to cool rooms on lower floors due to the building’s design and insulation.

4. Frequency of Use
How often you plan to use your AC will affect its longevity and efficiency. Frequent use may warrant an energy-efficient model, while occasional use might mean you can opt for a less expensive option.

5. Filter Location
Regular cleaning of the filter is important for maintaining air quality and efficiency. Ensure the filter is easily accessible for convenient maintenance.

6. Warranty Period
Different brands offer varying warranty periods. A longer warranty often indicates higher confidence in the product’s durability. Make sure to check the warranty details before purchasing.

Frequently Asked Questions about Air Conditioners

1. What AC size should I consider for my apartment?
It’s important to choose the right size of AC. If it’s too small, it will struggle to cool the room, and if it’s too large, it can result in inefficient operation. Make sure to pick one based on the size of your room.

2. Why do I have to take the star rating seriously?
The star rating is a key indicator of energy efficiency. Higher star ratings mean better energy savings and lower electricity bills, which is especially important for long-term use.

3. Should I opt for an Inverter AC if I won’t use it often?
Inverter ACs are more efficient and save energy, especially for frequent use. However, if you don’t plan to use the AC often, a regular model might be more cost-effective.

4. Why is the price difference between a BEE 3-star AC and an inverter AC so large?
Inverter ACs are more energy-efficient, which results in higher upfront costs but savings in the long run. If energy bills are a concern, investing in an inverter AC might be worthwhile.

5. Can I buy a window AC if I can’t afford a split AC?
If a split AC is out of your budget, a window AC can be a cost-effective option. However, it’s recommended to opt for a window AC with a high energy rating and cooling capacity for better performance.

Air Conditioner Buying Tips

1. Energy Efficiency is Everything
Always choose an AC with a high energy rating to avoid high energy bills, especially in areas with high electricity tariffs.

2. Size Matters
Ensure the AC size matches your room’s dimensions for optimal cooling. A larger AC is more capable of cooling a bigger space.

3. Noise Level
If you are sensitive to noise, consider checking the noise level of the AC before making a purchase. Split ACs are generally quieter than window or portable models.
