Quiet, ice cold, very satisfying unit

This unit is super quiet and performs very well. It replaced a traditional 1.5-ton unit upstairs, and the result has been highly satisfying. One minor drawback is that switching to R454 refrigerant makes adding refrigerant a little less convenient.

Pros

+ super quiet
+ ice cold
+ performs well
+ satisfying replacement

Cons

− R454 refrigerant makes adding refrigerant less convenient
