How you handle leaving a job site is as equally important as how you handle arriving and conducting the repair or installation. You should not rush this part of the process. Before leaving you must make sure the system is operating properly and that you have not forgotten or omitted any part of the job that may result in a return visit to the customer. For example:
• Make sure to check that no service ports are leaking refrigerant. It is possible these ports may be leaking a small amount of refrigerant after you have removed your hoses. It is also a very good practice to replace any caps removed or missing during a service call, including those used to cover any service valve stems or access ports.
