I'm using panasonic all across my house. And I kinda agree with you. I've got two 1 hp and one 2 hp. Not having wind slowness problem but keep needing to service I dunno whether its because not installed properly (the air cond contractor told me the initial installation was not proper and the water kept flowing back and causing freeze). Thing is i have fixed that problem but it seems the damage is permanent...it just doesn't function well now
