We all know how to operate an AC (air conditioner)—simply press a button on the remote or give a command to a smart speaker (like Alexa), and the cool air starts flowing. But have you ever considered *how* you turn your AC off?

Most people simply flip the wall switch or trip the MCB to turn off the AC. If you do this too, you are unknowingly shortening your AC's lifespan. To ensure efficient cooling and keep the AC running trouble-free for years, it is crucial to turn it off correctly. Let’s look at the right way to do it.

Why is turning off the AC directly via the main switch (MCB) wrong?
When you turn off the AC directly from the main switch or MCB, the power supply is cut off abruptly. This causes the AC's fan and compressor to stop suddenly, which is very harmful to the machine.

Think of it this way: when you turn the AC on, the fan starts first, and the compressor kicks in a few seconds later. The shutdown process should follow the reverse order. Repeatedly shutting down the AC abruptly puts extra strain on the compressor, and eventually, it could stop working altogether.

The correct way to turn off the AC
Always use the remote to turn off the AC.
The Process: When you turn off the AC using the remote, the machine follows a specific sequence. First, the fan stops; then, the AC flaps close; and finally, the compressor shuts down smoothly.
The Benefit: This prevents sudden strain on any part of the machine and extends the AC's lifespan.
Important Tip: If you are going away for an extended period, first turn off the AC using the remote. Once it has completely powered down and gone silent, switch off the wall outlet and unplug the unit.

Remote Care
When the summer season ends and the AC will not be used for months, remove the batteries from the remote. If you fail to do this, the battery acid could leak due to prolonged storage, potentially ruining the remote permanently.

Buying a New AC? Inverter vs. Non-Inverter AC
If you are planning to buy a new AC, it is important to understand the difference between these two types:

1. Non-Inverter AC
The compressor in these units runs at a fixed speed. It shuts off when the room cools down and restarts when the temperature rises. Due to this frequent on-off cycling, these ACs consume a significant amount of electricity.

2. Inverter AC
In an inverter AC, the compressor runs continuously but automatically adjusts its speed based on the room temperature. It does not shut off completely.

Understand with a Car Analogy:
When you repeatedly stop and start a car in first gear amidst heavy traffic, fuel consumption increases. This is similar to how a non-inverter AC operates.

Conversely, when you drive a car on the highway in top gear at a steady speed (80–100 km/h), it delivers excellent mileage.

An inverter AC functions like that car on the highway. It cools the room quickly and maintains the temperature by running at a steady, smooth speed, resulting in substantial savings on your electricity bill.
