Any brand will cause problems if you don't know how to use it.
But certain brands last longer and some are not. Service centers, electrical shops opinion will be more accurate than forum's review.
In general, non inverter last longer than inverter models since the components used different. Non inverter in general using thermostate to control outdoor unit's cut in/out while inverter is using sensors, IC to control.
If you want an air cond to be "noisy", off all the features and set to the lowest temperature, fan speed at max.
from my experience with inverter vs. non-inverter models under constant on conditions (24/7, set to 28/27 degrees only, non-full load, regularly cleaned, no chemical wash, dismantling only rarely if at all) i can say that after a few years - no matter which model you use - non-inverter units start to give issues at the outside compressor due to the constand on/off. cheap units tend to last maybe 2 yrs and then the bearing rattles. same goes for the inside blower fan. better brands (carrier, panasonic, etc.) tend to just have the outside compressor problem, the blower fan and stuff seems to last and stays quiet. also the outside compressor casing rusts, the cheaper the faster.
i never had any other major issues with any aircon i used like this, no controller board spoil etc.
inverter: running 24/7 now for up to 7 years: issues (all panasonic) none besides the 2 HB horizontal flap motor died on me (flap falls instead moving up / down so i set it not to move). no getting noisy, nothing. outside also nothing besides a bit of rust near the connecting pipes at the casing. makes sense, no on-off all the time makes them last actually longer a bit.
