How to choose the best AC for your home or office?

If you also want to buy a great air condition for your home or office to get relief from the heat, then definitely read this article. In this article, we will know how to buy the best air condition according to your need or budget.

By the way, there are many air condition brands in the market and each brand has different air condition models. In such a situation, we and you get confused about which air conditioner, or which air conditioner will be the most accurate for my needs.

Before knowing about air conditioners, let us know how much capacity air conditions you should buy, such as 1 ton, 1.5 ton or 2 ton.

What is 1 Ton, 1.5 Ton and 2 Ton AC?

Like other electronic devices, there is also a measuring unit for air condition. The British Thermal Unit (BTU) is used to measure the capacity of the air condition. The more BTU will be, the more the air condition capacity will be as much as the air condition will be able to cool a big room or hall.

But if we measure the capacity of air conditions in BTU, then what is this 1 ton, 1.5 ton and 2 ton?

Let us also solve this puzzle. You buy an air condition of any brand, every air condition product has a model number. The secret of BTU and Ton is hidden in this model number, let's know how.

In all models of air conditions, there is an Even number of 2 digits, generally it is 12, 18, 24. Now, divide these two digits even numbers from 12, and that's all, this will be the capacity of your air condition.

Examples:

Some of the models are - CS/CU-SU24AKY3W, ID512ZNURS, RAS.D318PCCIBS

  • If the model number has "12", it's a 1-ton unit (12 / 12 = 1).
  • If the model number has "18", it's a 1.5-ton unit (18 / 12 = 1.5).
  • If the model number has "24", it's a 24-ton unit (24 / 12 = 2).

In short, 1 ton is equal to 12,000 BTU (British Thermal Units) per hour.

So, 1 ton AC means, it can extract 12,000 BTUs heat from a room per hour. It is suitable for small to moderate-sized rooms, usually about 100–150 square feet, but the actual needs may vary. Similarly, 1.5 ton AC means it can extract 18,000 BTUs of heat from a room/ hour. Hence, 1.5 Ton, 2 Ton Air Conditions are suitable for a larger room/ space.

AC Capacity Requirement by Room Size

Room Size AC Capacity Required
Up to 150 sq. Ft. 1 ton
150-200 sq. Ft. 1.5 ton
200-300 sq. Ft. 2 ton

Windows AC or Split AC?

Let's move forward now and know whether we should take a Window AC or Split AC? In clear terms, it depends completely on you, like what your budget is, how is your room in the hall. Because both types of AC, whether it is window AC or Split AC, you are going to get good cooling.

Let's have a quick differences between Window and Split AC. Window AC are easy to install compare to Split AC as it contains 2 units (Indoor unit and Outdoor unit). Split AC have very little noise than Window AC. And of course, window AC is cheaper than split AC.

Factors of Good Air conditions

Let us know about some factors that should be in an air condition.

Energy Efficiency:

Energy Efficiency in an AC means how much cooling output the air condition produces for the amount of consumed energy. This is one of the key factors to buy an Air condition. In simple words, the air conditioner gives more cooling with low energy consumption, which results in a lower electricity/ energy bill.

Energy Efficiency Ratio (EER) measures the cooling output of Air Condition per hour each watt.For better energy savings higher EER is required.

Inverter Compressor

The Inverter Compressor feature is one of the modern features available in Air Condition. The traditional AC has a fixed speed compressor, while inverter-based AC automatically manages the speed of the compressor, and this way it becomes more efficient while providing maximum cooling. Inverter AC frequently manages the compressor's speed to maintain the required temperature.

Convertible Mode

Today, most of the AC offers convertible modes such as 4-in-1 convertible mode, 5-in-1 and 6-in-1 convertible modes. This feature allows to adjust different cooling modes based on your need. For example, if you 5-in-1 convertible mode AC then you can set your AC capacity to 40%, 60%, 80%, 100% or even 120%. So, if the weather is pleasant and the room size is not large, then you can set the AC capacity to 80% or 60% or even 40%, which will help you to save your electricity bill. I recommend this a must-have feature in all AC.

Air Quality Feature

This feature helps to improve the indoor air quality. It ensures to filter the particles, humidity and provides proper ventilation. In modern AC i.e. AC launched in recent years such 2024 or 2025, they uses HEPA filter feature. The HEPA feature helps to capture small particles of dust and even bacteria and viruses.HEPA filter is capable of removing small particles of size 0.3 microns.

Good to have Air condition Features in 2025

Stablizer Free Operation

This is one of the good-to-have feature in any air condition. However, I recommend using any normal stabiliser with your air condition. This will give a longer life to your AC.

Smart Wifi AC

Today, most of the brand has introduced smart AC. It means you can opearte your air condition using your mobile app and also with AI such as Google homes and Alexa.

Self Cleaning

This feature helps to reduce the maintanance cost of your air condition. Using this feature, the AC offers maximum cooling with less manual cleaning.
