Types of Air Conditioners

Split AC

Split AC provides cooling from different areas within a home. Split ACs can cool different rooms at different temperatures. It includes two or more parts. One is the condenser unit that can be installed outdoors, the compact or evaporative units mounted on walls. These parts are connected with conduits, that carry power and refrigerant lines.

Window AC

Window AC is known as a unitary unit installed in the window of a room.
These types of ACs have an exhaust system that pushes hot air out the back and side. It is suitable for the small room and can cool one room at a time. These are inexpensive and are ideal for small apartments and home.

Inverter AC

An Inverter AC is the latest technology. It is used to control the speed of the compressor motor and also regulates the temperature. No doubt Inverter ACs are bit expensive but saves bills.

How to Choose the Best AC for Home & Office?

Size of the Room

First, determine the size of the room and choose Air Conditioner according to it. Different ACs have cooling capacity depending on the size of your room. A one ton AC is suitable for a small room. Whereas 1.5 ton AC is suitable for medium to larger size rooms. The electricity consumption of an AC depends on the amount of heat present in the room. If you are planning to buy Ac for your living area then Split Ac will be the good option for you.

Workings of the Air Conditioner

The Air Conditioner removes the heat inside the room, and one gets the cool air inside the room. However, the ACs doesn’t generate cooling, it only removes excess heat inside the room and thus cooling the room.

  • AC has a refrigerant gas, and it first compresses this gas and turns it into a high-pressure hot liquid.
  • The hot liquid then flows through the condenser coils where the heat escapes while cooling the liquid.
  • After that, the expansion valves convert the high-pressure liquid into low pressure.
  • The low-pressure liquid flows through the evaporator coils of the AC. It absorbs the heat from the room and turns it into liquid gas once again.
  • This process keeps on repeating.

Size of the AC

To select the size of the AC one must determine the area of the room. If the area of the room is small to medium, then you need 1 ton of AC. In case of a larger room, one must need 1.5 to 2 ton AC. You can go with Hitachi 1.5 ton AC or Blue Star AC. However, the location of the room also takes place.

AC in TonsSpace
0.75 TonsSmall Bedrooms or Office Cabins
1 TonSmall rooms or Conference Hall
1.5 TonsMedium size room or Master Bedroom
2 TonsLiving room, Hall or Large Workspace

Power Consumption

In summer months the ACs tend to work on day and night or at least 4 to 8 hours a day. With this much amount of daily usage, it is quite obvious that electricity bill will go high. As per the consumption of electricity, it gets a power rating by the Bureau Of Energy Efficiency(BEE). When AC consumes less electricity that BEE ratings go high. The more electricity consumption ACs have fewer star ratings and that is the important factor to consider to choose the Ac for your home.


The AC has some common and basic features like auto mode, temperature control, fixed speed and turbo features etc. The other additional features with technology advancements includes sleep mode, fan-speed and various advanced filters that removes the pollutants and dust from the air.


Price is an important factor that plays a significant role. AC is a one-time investment, and you have to use it for a longer period. One must invest in the best AC as you are going to use it for over ten years at least. ACs comes in a different price range and look for AC that is best suited to your budget.
