Inverter AC Advantages And Disadvantages

Advantages And Disadvantages Of Inverter AC

The Inverter Compressor was first developed by Toshiba, Japan for business usage with Cooling Appliances like Air Conditioning Unit. Toshiba has been growing rapidly in the airconditioning business and is considered as one of the most popular AC brand.While the basic types of compressors take in high electrical power, the inverter compressors utilize electricity in an optimized method.

Normal inverter compressors constantly run at the very same speed, whereas, inverter compressors changes speed when the need changes. It manages the flow of refrigerant throughout the refrigeration cycle.

Inverter ACs has many benefits, but there are some downsides to the inverter air conditioning system as well. At the end of the post, you will be able to understand the common pros and cons of inverter compressors clearly.

Advantages Of Inverter Air Conditioner

Inverter air conditioners use electricity in an optimal method. Generally, more the fluctuations in electrical load and greater the working volume of the room lead to regular operation of the compressor at a quick speed. It leads to greater electricity usage. In the case of the inverter air conditioner, the speed of the compressor differs with the working load, decreasing the electrical energy costs.

An inverter type air conditioner (be it, window acs, split acs or portable acs) adjust the speed of the compressor to control the refrigerant gas flow rate, thereby consuming less current and power.

Inverter Air Conditioners also works fantastic when there is a change in the load like marriage hall, indoor occasions, conference room, large offices.

Using an Inverter air conditioner may assist you to conserve the money, and the additional expenditure can be recuperated within a couple of months.

It is suitable for all size of rooms. In a big space, it might consume a bit more electrical energy compared to a smaller sized space as electrical energy intake depends upon the load. Greater the room size more will be the load.

Uniform and constant room temperature can be maintained inside the space if you utilize an inverter a/c.

If you prepare to utilize solar power for cooling, inverter, a/c is the most popular option.

It can cool down the space at a much greater rate than non-inverter air conditioning system.

In Inverter air conditioning unit, the sound and vibration are substantially decreased.

Another advantage of the inverter ac is that the compressor lasts longer as compared to regular ac’s preventing you from facing compressor issues such as “ac compressor not working, but fan is running” in the future. This is because the compressor takes the most damage during startup and since the inverter ac starts slowly, it limits the damage caused to the compressor.

Disadvantages of Inverter Ac

An inverter A/C typically costs almost 20-25 % higher than typical AC of the same ranking. So unless the user is not very heavy or the electrical power expense is not that high, it might use up to 5-7 years to recover the high upfront expense of an inverter A/C.

An inverter A/C consists of really sophisticated circuitry and a reasonably greater number of moving parts, so the upkeep expense of inverter A/C will end up being greater.

In an inverter AC, the compressor adjusts its speed according to the heat load in space. If there is a periodic leak of cooling from the space, the compressor will run at greater speed, thus increasing power intake.

Dehumidification is one more benefit of a/c. It is accomplished when the air comes in contact with a cooled air heat exchanger (indoor unit). Nevertheless, in inverter AC, the degree of chilling achieved is varied according to heat load rendering it insufficient for dehumidification in case the set temperature is not extremely low.

The compressor paces approximately wanted speed with some programmed lag. There is some requisite amount of time for an inverter A/C to accomplish a preferred degree of cooling in the initial stage.

If an inverter AC has a lower capacity than required, the compressor performs at greater speeds for a longer duration of time, consequently increasing power usage. On the other hand, if an inverter A/C has a higher capacity than heat load, it will run for short cycles and render the space over cooled and uneasy. Nevertheless, these problems shall likewise persist with a normal Air Conditioner as well.

An inverter Air Conditioner consists of very advanced mechanisms. Frequently regional, less certified specialists are unable to comprehend the problem and end up escalating the problems instead of solving them. It is encouraged that one should only get it serviced/repaired from initial devices manufacturer’s professional, which typically is expensive if the unit is not under service warranty. The availability of professional is likewise something important to be thought about.

Inverter AC Vs Non-Inverter AC: Which Is Best For You?

Non-Inverter ACInverter AC
Compressor either works at full speed or stops completely once the set temperature is reached.It has a frequency compressor which constantly adjusts its speed based on room temperature & desired temperature
Creates lot of sound as the outdoor unit keeps turning ON & OFFAn inverter AC is a lot quieter and noiseless as the outdoor unit doesn’t turn ON & OFF but adjusts its fan speed.
Once the room has reached the set temperature, compressor is turned OFF.Works towards maintaining temperature in a room rather than simply cooling it. 
As compressor keeps turning ON & OFF, it consumes lot of energy.Can help you save up to a maximum of 50% compared to convectional ACs
Initial cost is comparatively cheaper and budget-friendly.Initial cost of Inverter AC is comparatively higher than the non-inverter conventional air conditioners.
Has the standard air filtersInverter ACs come with a wide range of air filters such as carbon, HEPA, blu, etc.,
Maintenance & spare parts cost is lessMaintenance & Spare parts cost is lot higher.
Best for Home or places with occasional use or just for 7-10 hours a day.Best for office spaces or places where the AC is being used for more than 12 hours a day.

While there is so still so much space for growth in terms of how air conditioners affect the environment, inverter ACs take us a step closer to achieving the goal. After weighing in the positives and negatives, you may decide to buy an inverter ac; if you decide to do so, you could read reviews on inverter ACs online to choose the best and most efficient ac.


1. Are Inverter Ac’s Better?

The answer to this question would depend on the context; if we talk about the price, inverter air conditioners are costlier than regular air conditioners. In terms of efficiency, the inverter air conditioner is a lot better than a standard air conditioner. This is because an inverter air conditioner consumes very little electricity in comparison to a traditional air conditioner. In terms of noise, an inverter air conditioner is also quieter.

2. Which Brand Inverter AC Is Best?

In another article of ours called “The Best AC Brands In The World,” we have mentioned a list of brands that we believe give the best value for money inverter air conditioners. In terms of value for money and the quality of the inverter air conditioners that are being made, we believe they are the best.

3. What Is Dual Inverter AC?

A regular inverter ac uses a variable speed single cylinder compressor with a single compression chamber. The HVAC system’s cooling capacity is modulated by the compressor, which is operated by the inverter. A dual inverter ac uses a twin rotary compressor that has 2 compression chambers. These 2 compression chambers produce a phase difference of 180° compression timing. The rotary compressors of the dual inverter ac work between 720 rpm (Revolution Per Minute) and 9000 rpm.
