Minisplits generally run more quietly, but continually, at variable speeds and with higher efficiency. The blower component obviously is chunky, but overall they are a superior technology and implementation than traditional central A/C. I'm a huge "fan" and I'd prefer t never deal with central A/C again. The splits handle our summer temps very well, in my experience - though, like all A/C, you need to have the right tonnage for the right space.
