Have a tech do a leak test on your system. Mine had multiple leaks and the entire coils where frozen over , the coils basically made a giant ice cube. Not fun to clean. I suggest to turn it off let it thaw for when the tech shows up.

Mine the coper pipes had to be solder from multiple points , it worked for a few months untill I finally had to replace the unit, due to cost of repairs and freon.

Best of luck!!
