Best AC recommendations

I want to buy 3 ACs for new house in Mumbai Living room - approx 150sqft Master bedroom - 125sqft Common bedroom (parent) - 100sqft

So parent use very little AC. So I am ok here to go with mid range AC For me, I'll definitely going to use it at night for a couple of hours for sure. Living room - depends if temperature is more or guests have come. So usage won't be too much but maybe 2-4 hours

Suggest me good brands AC. Majorly I am looking for long term durable AC with good cooling and less quality and service issues. Also if any problem happens the service from the brand should be good enough
