Yes that coil is fine IF the proper tx was installed
Options include finding the problem with your system or starting over
If you go with just a new condenser you can use the same air handler but I would replace at a minimum the indoor coil but would recommend changing the line set as well
Cheapest option have a QUALIFIED tech not a parts changer or salesman come out and fix your system I would recommend useing the contractor locator on here to find said tech
