What Is Dual Inverter AC?

Inverter ACs are meant for low energy consumption. However, the intensity of sound from the compressor may bother you.

The sound is due to vibration caused by the compressor’s rotary shaft and the RPM at which it runs at peak load.

A Dual Inverter AC solves both problems. It runs quietly and offers better efficiency than a single inverter AC. In this article, we will learn more about Dual Inverter ACs.

What Is Dual Inverter AC?

Inverter ACs are nothing new. Almost all the split ACs available in the market are inverter ACs. Dual AC is something new, and only a few manufacturers offer this feature in their ACs.

A Dual-Inverter AC uses two rotaries with a 180-degree phase difference in their compression timings.

The BLDC motors used in these dual-inverter ACs can offer the same level of compression at a much lower speed than a single-inverter compressor. Due to this, you will also get less sound and less vibration.

Dual inverter ACs also save more power than single-inverter AC as they can run at a much lower frequency, generally in the 700-8000 RPM range.

The lower frequency allows the AC to run at a much lower capacity based on the heat load. For example, a 2-ton AC can run as a 1-ton or even a 0.5-ton AC.

Benefits Of Dual Inverter AC

Dual inverter ACs have several benefits, as mentioned below. The benefits are similar to those of Inverter ACs, but the added benefits are less sound and less vibration.

Less Sound And Vibration

Due to the use of dual rotors, the frequency at which dual inverter AC runs is much lower than that of a single inverter AC. That is why there is less vibration, and less vibration means less sound, too.

Durability

A dual inverter AC has more parts than a single inverter AC. However, a dual inverter AC always runs at a lower speed, even at the peak load, putting less stress on its counterparts.

Less stress means less wear and tear and fewer chances of failure. A well-maintained dual inverter AC has at least 30-40% more lifespan than a single inverter AC

Less Power Consumption

There are a few factors that contribute to the low power consumption of dual inverter ACs. First, the low speed of the compressors helps with low power consumption, and second, less stress on other counterparts elevates the benefits even more.

Please note that although dual inverter ACs run at a much lower speed, they offer the same amount of cooling at a much faster rate than a single inverter AC.

A well-maintained and timely serviced dual inverter AC can offer up to 50% less power consumption than a single inverter AC.

Disadvantages Of Inverter AC

Dual Inverter ACs are good, but there are a couple of drawbacks that you will have to deal with in case you plan to buy a dual-inverter AC

Initial Cost

The running cost is low, but the initial cost is higher than that of any single inverter AC. This is due to the use of dual rotary compressors and expensive sensors.

You need to figure out how quickly you can break even the additional cost you will likely spend on the dual inverter AC. If it is 3-5 years, it makes a good deal. Otherwise, a single inverter AC will yield more savings for low usage.

Expensive Repairs

If something goes wrong with your dual inverter AC, you need to be ready to face an expensive bill. Dual inverter technology is new, and many technicians do not know how to deal with it. Those who know charge a premium. The regular servicing cost will also be higher.

Conclusion: Should You Buy A Dual Inverter AC?

Why not? But buy a dual-inverter AC only if your usage is high. Otherwise, it might take more than 10 years to recover the extra money you spend on it.

Ten years is usually the maximum lifespan of an AC, so by the time you can recover your extra money, the AC will already have reached its maximum life.
