The Inverter Technology is the latest innovation in the field of air conditioning that has taken the market by storm. Although, it is a bit more expensive than non-inverter air conditioners, but it saves much more electricity in the long run. Inverter ACs function based on the technology of compressors and changes the speed of cooling depending on the heat load of the room. An inverter controls the speed of the compressor motor and constantly regulates the temperature of the AC and delivers precise cooling or heating power as required. This helps to reduce the energy cost of running the AC. Increased efficiency of inverter ACs extends the life span of the parts and eliminates sharp load fluctuations. This reduces the operating cost of the AC.
Inverter ACs are better than Non-inverter ACs in a number of ways:
- Inverter ACs are 30 to 50% cheaper to run because they consume much less power compared to normal split ACs
- Inverter AC achieve desired temperature far quicker than non-inverter ACs
- The start up time of inverter ACs in reduced by 30%
- Inverter ACs are much quieter than regular split ACs
- There are no temperature fluctuations in inverter ACs which maximizes comfort level
- Extended life of the compressor due to no voltage peaks
Commonly Used Terms
Tonnage – Whether you buy a normal split AC or inverter AC, it is important to consider the tonnage. Tonnage is the measure of the cooling capacity of an AC as per size and demand of the room. A 1 Ton AC has the capacity to cool 1000kgs of air in 24 hours.
Efficiency – Efficiency of an AC is measured in Star rating. The more stars, the more energy efficient the AC. An AC with 5 star rating saves more energy compared to an AC with 3 star rating.
Coil – ACs have either aluminium or copper condenser coil in the cooling unit. Although, copper coils are superior in quality compared to aluminium coils, but both are susceptible to corrosion, so it is important to have anti-corrosive coating.

Things to Know About Inverter Air Conditioners
Inverter Air conditioners look same as normal split air conditioners, but they are fitted with a device called an inverter that controls the frequency of electricity supplied to the compressor motor which helps to maintain uniform temperature and improve power saving.
Difference between Inverter AC and Non-inverter AC
While both inverter ACs and non-inverter ACs have compressors, non-inverter ACs have fixed compressors that can’t increase or decrease their speed as per requirement, they only work on a given capacity. That’s why non-inverter ACs makes the rooms extremely chilly or a bit warm. The compressor of non-inverter ACs stop on reaching the set temperature, and turns on once the temperature in the room rises. This starting and stopping of the compressor consumes more electricity.
In case of inverter ACs, the compressor never stops, but it draws power in accordance to the heat load. Variable speed motors present in inverter ACs change the rate of power intake as per requirement which in turn saves electricity.
Points to Note While Buying an AC
Air Conditioner capacities – Residential AC units range from 1 to 5 tons, but in this article, we are talking about 1 to 1.5 ton ACs. Ton is the unit of measurement of the air conditioning system’s capacity. A 1 ton split AC is good enough for cooling small bedrooms and office cabins. 1.5 ton ACs are required for large conference rooms, master bedrooms and drawing rooms. Selecting the tonnage of an AC also depends on maximum temperatures in the place you live, window space in your room and the floor you live on.
Beneficial Features in an Inverter AC
While most air conditioners come with a number of features, modes and functions, here are a few features that are truly useful.
Air Purifier – Many inverter ACs come with micro filters, HD filter, sliver ion filter, active carbon filter, dust filter, etc. that helps to purify the air before it is released into the room.
Dehumidifier – Inverter ACs also have dehumidifiers that remove excess moisture and humidity from the air when the outside air has high humidity or during monsoon season which in turn reduces stickiness.
Auto Restart – Inverter ACs come with Auto Restart feature that saves the settings in a memory chip. It allows the AC to turn on with the saved settings after a power outage.
Tips to save electricity while Using Inverter AC
The first one is an obvious tip. Keep the windows and doors properly shut while using the AC and cover any large gaps in windows and other outlets in any insulation material such as glass, thermocol, cloth, etc.
Pull the curtains over transparent windows while using the AC.
Set up a false ceiling in the room to reduce the heat coming from the roof. This will help to lower power consumption.
Maintain the AC at a comfortable temperature of 24 to 25 degree C.
Don’t decrease the temperature of the AC rapidly in order to speed up the cooling process, use Fast Cool or Turbo mode instead.
Use the AC in Sleep Mode at night. In sleep mode, the AC automatically increases the temperature of the room every hour and helps to maintain a comfortable temperature and saves power.
Maintain the performance and power efficiency of the AC by keeping it clean and well-serviced. Service your AC at least once in every 4 months and clean the filters of the indoor unit as frequently as possible.
If you have decided to buy an inverter AC then it is best to purchase a quality product from a reputed brand. It might be a bit costly than other models but it will keep you in profit in the long run because of its lower running and maintenance cost.
