Service support is not propery done on time once you complaint on customer care no.
Cooling and sound is usually making by llyod ac sometimes it wont cover the full areas of rooms and hall.
If talk about quality is not so good like others ac companies and its is non durable for long time it might be go on max 5 years only.
That is totally wastage of money in inversting in llyod air conditions rather than that you should buy some other companies air conditioning solution for better summer.
