Yup, I agree with this point.
I did use 1 unit 2.5 hp, 2 unit 2hp inverter, 2 unit 1hp inverter, 1 unit 1.5 inverter..
Overall everything work great ,been using it more than 5 years..
Service it once two years...
No problem at all.

But the price is expensive than pana n daikin..
For long term use I think is worth.
Mitsubishi Heavy Duty will be cheaper but I using Mitsubishi Electric .
Mitsubishi Electric design air-cond for factory type usage.
Heavy duty is for home usage.
