I decided to replace the portable AC unit in my bedroom with a window type in order to gain more floor space and easier access to the closet. The portable is a Soleus 9K BTU that has been a fine, quiet performer for the past two years, but suddenly after never being necessary, it had to have its condensate tank emptied twice in less than two weeks, so I decided this could be an indication of a bigger problem and that it would be a good time to make the switch to a window unit. I paid $50 for it so definitely got my money's worth.
I found a Panasonic model CWXC85HU (see image below), which the seller told me was the quietest window AC available when it was purchased new. I like its simple remote and the fact that unit isn't
"smart" and doesn't have any app nonsense. It blows cold as ice and cools the room down quickly, but it vibrates loud enough to be heard in most other parts of the house. I've tried to fashion isolators for it, but the rhythmic vibration remains and plastic parts on the front of the unit (intake and output grilles) often rattle loudly. Any respite is brief, and it seems like the compressor's vibration fluctuates during the course of operation for long periods, which once again makes both the vibration and the rattling even louder, and it's impossible to sleep. Adjusting the leveling screws on the outside hasn't helped. Currently, a folded up business card shoved between the bottom front of the unit and the inside window ledge is helping with the rattling, but the vibration level is still too much and I'm sure this band-aid is tenuous. I'm wondering if the compressor has a bad isolator. If anyone is familiar with this series of Panasonic, I'd welcome some advice on what to try next, but am not so sure I want to extract the cooling system from its casing in an attempt to resolve the trouble, either.
I've done some searching on line and it seems the Panasonic's 7.8K BTU is more than I need. The new(er) LG 5K-6K BTU window units are said to be the quietest. My sister has an older Toshiba in her guest room and it's fairly quiet. Midea's units all seem to develop issues (mold in particular) quickly. I've always been pleased with any Panasonic product I've owned, but this AC unit is intolerable. I do know that the extra space and easier closet access has already made a window unit preferable to a portable. I'm willing to buy new if that's what it will take to allow for a peaceful night's sleep.
