Room Size – Choose Capacity of AC according to your room size

The quantity of heat that an air conditioning (AC) unit can remove from a room in an hour is measured in tonnes, which is the capacity of the AC. Here is a general guide to assist you in choosing the right AC capacity for your space:

AC CapacityRoom SizeAC Capacity (For Direct Sun Light)*
0.75 Ton80-120 Square feet1 Ton
1 Ton120-180 Square feet1.5 Ton
1.5 Ton180-250 Square feet2.0 Ton
2 Ton250-300 Square feet2.0 Ton
(*) = Like Top floor

AC capacity that you use may change, its depend on the room’s height, insulation, number of windows, and regional climate so keep this on your mind. If you’re unclear of the right amount of AC for your space, it’s advisable to speak with an HVAC expert who can provide a more precise evaluation. For the best cooling and energy efficiency, it’s critical to choose the correct capacity for your air conditioner.

Type of AC

There are several types of air conditioning (AC) systems available, each with its own set of advantages and disadvantages. The most common types are as follows:

  1. Window AC: This sort of AC unit is meant to cool a single room and is positioned on a window. They are often less expensive and easier to install, however they can be noisy and inefficient in comparison to other varieties.
  2. Split AC: Split AC units have two separate components: an inside unit and an outside unit. The indoor unit is put on a wall within the room, while the outdoor unit is installed outside the structure. In general, they are more energy-efficient and quieter than window units.
  3. Portable AC: This portable air conditioner has wheels and can be transported from one room to another. They are less powerful than window or split units, but they are easier to install and do not require permanent installation.
  4. Central AC: This kind of air conditioning system is designed to cool an entire building or home. It has a central unit that cools and circulates air to each room via ductwork. They are the most expensive and necessitate professional installation, but they deliver consistent cooling throughout the building.
  5. Ductless Mini-Split AC: This type of air conditioning system is similar to a split system but does not require ductwork. They feature zone cooling, which allows you to chill different rooms or sections individually, and are ideal for homes or offices.

The sort of AC unit you choose will ultimately depending on your specific needs and budget. Consider the size of the space, energy efficiency, noise level, and installation requirements before making a purchase.

Difference between Inverter and Non-Inverter AC

The biggest difference between an inverter and a non-inverter air conditioning (AC) system is how the compressor speed is controlled to manage room temperature. Here’s a breakdown of the distinctions:

Inverter Technology

The Inverter compressor can thinks and adjusts to what you need. The compressor has variable speed and frequency that adjusts depending on the temperature. It is worthwhile to invest in a longer-lasting, more energy-efficient air conditioner.

Advantages of Inverter ACs:

  1. Compressor Speed: In non-inverter air conditioners, the compressor has a fixed speed and is either on or off. This causes a quick surge of cool air when the air conditioner is turned on, followed by periods of no cooling. Inverter air conditioners, on the other hand, have a variable-speed compressor that can change its speed based on the temperature of the room. This gives a more consistent and even cooling experience as the compressor can slow down or speed up as needed.
  2. Energy Efficiency: Inverter air conditioners are generally more energy efficient than non-inverter air conditioners since they do not have to turn on and off repeatedly to maintain the desired temperature. Instead, the compressor adjusts its speed to match the room’s cooling needs, resulting in less energy waste and less expensive electricity costs. Inverter air conditioners use less energy because the compressor does not have to achieve maximum cooling speeds as frequently.
  3. Noise Level: Inverter ACs are typically quieter than non-inverter ACs because they operate at a lower sound level due to their variable speed compressor.
  4. Cost: Inverter air conditioners are often more expensive than non-inverter air conditioners since they require more modern technology and components. However, the cost can be mitigated by the energy savings and enhanced comfort that they bring.

Energy Star Rating

Higher star ratings cost a bit more initially but consume much less power, and hence save money on your electricity bill in the long run. Compressor material in the AC also contributes to energy consumption. Compressors made of copper are more energy efficient than aluminium ones. It also depend upon your uses in a month or in a year, please check below.

Note – If your daily use is 4-5 hours in a day and 3-4 months in a year then you should go with 3 star AC while if your daily use is 6-8 hours and 5-7 months in a year you should go with 5 star AC.

A higher-rated air conditioner may be more expensive at initially, but it will save you money on your utility bills in the long run. It’s important to remember that the star rating system is updated every few years to reflect technological advancements. When buying an air conditioner, always look for the most recent star rating.

Extra features

  1. Remote Control: Most air conditioners come with a remote control that allows you to change the temperature and other settings from across the room.
  2. Timer: A timer option allows you to programme your air conditioner to switch on or off at a specific time, which can help you save energy and money.
  3. Sleep Mode: This option gradually adjusts the temperature throughout the night to help you sleep better.
  4. Dehumidifier: Some air conditioning systems include a dehumidifier function that removes excess moisture from the air, making your environment more pleasant and less prone to fungal formation.
  5. Air Purifier: Some air conditioner units integrate an air purifier that filters out dust, pollen, and other allergens, resulting in cleaner air.
  6. Auto-Cleaning: Some air conditioners have a self-cleaning mode that removes dust and grime from the unit, increasing efficiency and reducing the need for maintenance.
  7. Wi-Fi Connectivity: Some high-end AC units include Wi-Fi connectivity, allowing you to manage the unit via a smartphone app or voice commands.
