Bryant Heating & Cooling review: Bryant mini splits

We had these installed 2019. They have costs us thousands in repairs we have 4 wall units on 2 compressors. 4 years after installation, one problem after another. 1, all the coolant evaporated & we were told that the lid has to be checked because it becomes loose. 2. Bad wiring I. 1 & had to get a new board. The. , the board we t out on the other. Recently, something major went out. Parts had to be ordered & we waited for over a month while we had record cold winter. Now, the things keep turning off.
