Arrived and clients stated they had another company come out yo inspect why system was not cooling home well. Clients stated that certain duct runs had not been replaced. Inspected entire duct system to find that roughly 5-8 feet of old metal ducting was still left that we had connected to. Installers need to return and reattach new flex as close as possible to boot boxes. Found corporate to house not staying cool due to lack of insulation. Homeowners stated they are selling home and wish to not proceed at this time. Client also wants permits pulled as promised
