Its just over a year old, blows air slightly cooler than room temp no matter the setting.
Filters are clean, thinner pipe freezes over within a minute thicker gas pipe doesn't really change temp. The drainage pipe doesn't have any water dripping through the clear bulb, tubing is dry as a bone.
Have another AC identical and that one works fine, no frost and the water drains correctly. The only difference is it gets no direct sun in the morning and the piping has no dips/curves, this AC has a small dip, not sure if that would cause a problem? It worked fine during last summer and winter.
Will call Yodobashi after work just curious if anyone has experienced this?
