i hate aircon... makes the air inside dry and positive charged and the environment outside cold and wet
just walk around a city these days to notice how wet the microclimate is in winter
my preference for heating is old school carbon coils in quartz tubes like the original dim orange incandescent lamps... plus they give you lots of reddish IR light which i'm pretty sure is good for your health... just have to sit em close to you... and an air purifier for the dust, the air indoors in winter is abominable
