AC Unit out of freon
Need advice.... I have a 02 Bryant 3ton package unit that is not working. A technician came a few weeks ago as it was not working right. He said it was frozen and I saw that when he opened it. He checked for leaks around the main area and did not find any. He said it was low on freon and put in 3 pounds.
Today he was back as it is not working. It took him awhile to figure out that it was totally out of freon. So do I spend the money to fix or buy new? He seemed to discourage me from fixing and now a person is coming tomorrow to give quote on new system. He told me that with the cost of freon and leak test with labor I am already looking at a cost of 500 without parts. He said coils can be expensive. How long should this system last? I live in SC so run it a lot. Help me make the right decision. Fix or replace.
