Hello, A few weeks ago I had a service call to repair a zone damper. The tech new his stuff, removed and repaired the damper. All is working fine. The only problem is were he removed the damper, he had to cut the vinyl covered insulation, when he put it back he used duct tape. The tape keeps comming off after a few days. I have tried every brand from of duct tape from local depot. Is there a special tape for vinyl covered insulation? I hate to call the tech back for this.
