Help!! My cooling unit went out last night. Now keeping at 74 instead of 55.
We got a new unit about 7 years ago. My question is: do I replace the unit at about 2k or look into new unit/cabinet? This one is huge and holds about 400+ bottles. Should I get 2 smaller ones?
I’m kinds freaking out and don’t want everything to go bad.
Brands to avoid? Recommend Brands?
Thanks in advance!!
