    I have a Mitsubishi mini split that was installed last fall and we used it for heating over the winter and now when we started using it for cooling I've noticed a vinegar smell coming out of it. We have 5 zones but only one smells.

    Air filters and heat exchanger are clean, Mitsubishi tech support suggested I call the insrltaller and the installer never heard of anything like this. He's coming over to take a look on Friday but if any of you have some idea what's causing it or have experienced this, please let me know.

    Thanks!

    Does your unit have a removable filter which needs to be cleaned? I know when my car starts smelling like vinegar (actually closer to the smell of cat piss), it is time to replace the cabin air filter.

    I vacuum cleaned the filters which were not too dirty to begin with....
