I also have a pinguino in my office. I think it's on it's 4th or 5th cooling season. Only issue with it is that the squirrel cage fan it uses has become unstable and rubs against the housing, causing varying levels of squeaking sound noise. It's mostly cooling equipment in a mostly unattended office, so I haven't bothered with it too much, but at some point I'll look for a replacement fan. Installation, in my case, involved drilling two dryer vent holes into the wall (one intake, one outlet) and plugging the unit into the wall outlet.
