When you delete the Service applications, their Application Pools will not get deleted – They’ll become orphan/unused. So later when you create a new service application with same application pool, SharePoint will throw an error message: Application pool is already in use!

“An object of the type Microsoft.SharePoint.Administration.SPIisWebServiceApplicationPool named “Excel Service Application Pool” already exists under the parent Microsoft.SharePoint.Administration.SPIisWebServiceSettings named “SharePoint Web Services”. Rename your object or delete the existing object.”
