I remember the ceiling and wall vibrating goodness of that cold air maker in my hot as fk shitbox home back in the day. Electricity didn't cost so much back in those days and the aircon drowned out the traffic so everything was good. Simpler times.
Are modern window\box aircons much the same? Or should I be saving for a little installation technician to put in a split system?
Depends on make, model and the structure of the window/surrounds… some are whisper quiet.. but I dont think they are as efficent as splits, nor as good.
YMMV
