At First your service person didn't want to repair the Central Vaccuum , And He wanted to make sure I am going to pay him. But I assured him I will , The vacuum was under warranty and I should have called the Nutone Authorized dealer not to pay for the service, It was my mistake, but finally after your repair I send the invoice to nutone and they reimbursed us. Please tell your employee when they come for repair to a house like us , have must know that we are going to pay them anyways.
