I also check how easy it is to access the filter and whether the unit needs frequent servicing. A low-maintenance model is always better for me in the long run.
Build Quality and Durability
I want my AC unit to last, so I pay attention to build quality. A sturdy design gives me more confidence that the unit can handle regular use. I also read reviews to see whether other buyers have had issues with leaks, weak cooling, or early breakdowns. Durability is something I never ignore.
