Hi,Welcome to Just Answer, My name is Bryan,I look forward to helping you today. lets get started.
a couple of things on this, one if its getting loud the compressor is failing or has basicly failed already. you cant even get the compressor any longer for this unfortunately and if you could you are looking at more money in labor and freon replacment along with the compressor cost you could replace the unit cheaper, besides the fact that no one wants to deal with repairs on these. hope this helps and saves you a lot of agravation, thanks Bryan
