Bit noisy

What is Inverter AC

Smartest split AC technology in the latest market is Inverter AC. Inverter technology is highly energy saving, smart cooling and efficient.


Less power consumption

Cools faster without any noise

Not much load on the compressor, making it safe on household wiring


Expensive than split and window models

Need skilled technicians for repair

Internal parts are costly

Quick Tip: Better go for the latest model AC, as they are highly optimized and efficient for a longer period.

How to select size/capacity (Tonnage) of the AC

Select the right Tonnage

Selecting the size of an AC mainly depends on your room size or office size. Check for the cooling capacity of your AC, the temperature of your city, room orientation, number of windows in your room and floor in which your living before selecting your AC size.

To get the right size of AC or tonnage always refer to Tonnage calculator or do contact your AC brand customer care. Please specify your room size to the reference, as lower AC capacity may affect cooling and performance.

Select the right Tonnage

CapacityRoom Area
Up to 1.2 Ton ACFor Room size <= 120 sq. ft
1.4 to 1.5 Ton ACFor Room size 121 to 179 sq. ft
2 Ton or aboveFor Room size > = 180 sq. ft

Quick tip: Select the right tonnage for your room checking at the table. Also try to conceal your room well for long time cooling.

Inverter AC – Concept, Working, and Benefits

Inverter AC is the latest and smartest technology introduced in split AC. Technology in an Inverter AC evenly cools the room, by gradually increasing the cooling capacity. The compressor of an inverter AC runs at various ranges of speed to offer continuous cooling, without switching off and on. This reduces the stress on the AC compressor, improving efficiency and reducing power consumption.

If you are looking for better cooling, highly energy efficient and consistent cooling, invest on Inverter AC. Invert AC is very easy to maintain.

Benefits of Inverter AC

Low power consumption

Inverter AC is a smart investment, as it consumes less power as there is no frequent compressor switching. As a result, you will receive a less electricity bill.

Consistent cooling:

Due to smart compressor working, it varies its speed capacity according to room capacity for optimum cooling

Longer life:

As your Inverter AC compressor is not under cooling stress, load on the compressor is reduced, offering longer life span for AC.

Comparison between Inverter AC & Non-Inverter AC

               Function             Inverter AC             Non-Inverter AC


Variable speed compressor, adjusting according to room temperature. Compressor slows down when the room is cool and gains speed when the room temperature raisesFixed speed compressor. Compressor cut off when the room reaches specified temperature and again restarts when the room gets warm.



           Power consumption

As the compressor adjusts accordingly without load, inverter AC consumes less power.Due to the frequent compressor on and off modes, load increases, thereby consuming more power



Inverter AC operates quietly, as compressor motor is stress free.Bit noisy due to continuous on and off compressor operations



Room is maintained at a constant temperature with even cooling.Uneven room cooling due to varying temperatures.


              Life span

Compressor load is very less, improving the lifetime of the AC, lasting longerContinuous load on the compressor, decreases AC lifetime.




Expensive but long time investment. Additionally low maintenance and low power bills along with better performanceAffordable range to everyone for decent cooling effect.

Check the coils?

Nowadays ACs are built with aluminium coils, for cost-cutting but these coils offer less lifetime. If you are not hesitant for budget better ask for AC with copper coils.

Cooper coils are far much better than aluminium coils as they have a longer life and few leakage complaints

Copper Coil vs Aluminium Coil


Copper Coil vs Aluminium Coil
  • Copper coils are better heat transfers than aluminium
  • Copper coils are easy to maintain, clean and repaired easily when compared to aluminium ones
  • More copper metal is required to make coils whereas less aluminium metal is enough.
  • Aluminium coils are cheaper than the copper coils
  • Copper coils are very strong and durable than aluminium coils

Quick tip: Invest in Copper coil AC for improved performance and long lasting lifetime.

Look at the compressors

There are two different types of compressors available now in the market for AC – Reciprocating compressor and Rotary Compressor.

Look at the comparison between both to decide which one to opt to before buying an AC

Reciprocating Compressor:

This model is also called a piston air compressor having a cylinder and piston arrangement like an automobile engine. The piston compresses gas and the discharges with back and forth motion.


Easy to maintain

Works great even at high pressures.


Makes noise along with vibration

Can observer high-temperature air coming out of the compressor

Rotary air compressor

The rotary air compressor has specially designed a pair of rotors rotating in opposite directions making the air to pass at higher pressure.


Best for industries and big offices

Less noisy than reciprocating air compressors


Expensive than reciprocating compressor AC

Min air usage leading to corrosion, hence ideal for office use

Quick tip: If you need AC for cooling large areas like office, industries etc, go for the Rotary compressor model air conditioner. If you are just looking for a home purpose or small office or shop, the go for reciprocating air compressor AC.

Energy Star Rating

The Higher number of star ratings on your AC contributes to high energy efficiency. High star rating AC is a bit expensive but consumes less power, saving your bucks and even offer longer life.

The Bureau of Energy Efficiency (BEE) introduced a new star rating methodology known as “Indian Seasonal Energy Efficiency Ratio (ISEER) for air conditioners. Higher the ISEER rating more the saving from your AC.

ISEER is previously known as Engert star Rating(ESR), according to the rules of 2017. Latest BEE 2018 rules state that for non-inverter split ACs there is 2 point energy rating drop in 2018. So 2017 5 star non-inverter split AC in the market becomes 3 star AC in 2018.


Below chart shows energy and cost saving for a non-inverter AC with different star ratings.

energy consumption

Quick tip: Check the ISEER number on the BEE label present on AC or box outside to note down the rating. Always go for a higher star rating.

What Features You Must Look While Buying an Inverter AC

Cooling & Heating: Few AC models are built in with heater for room heating. Look for the heating feature to stay warm during winter.

Anti-Bacterial Filter: Additional antibacterial filter obstructs tiny harmful microorganisms like mites and bacteria for protection.

Dehumidifier: Get an AC with Dehumidifier to get rid of excess air moisture especially during monsoon season.

Cool coils: AC coils with copper metal cool the air faster, very easy to maintain eliminating corrosion thereby offering longer life span.
