Why can't they a part?
Answer Joseph, I think you're inquiring about the purchase of a compressor ? You may purchse the part, but you will not be able to repair the unit(install the part) unless you are a certified refrigerant and recovery technician, have a license or certificate to purchase the refrigerant, and the tools to recover the refrigerant and perform the soldering and swedging of the tubing. So, you would need a technician to install the part if you purchased it . Thanks and Good Luck.
