Unit is set and sealed on roof. Need to complete skirt around stand and seal to roof. System is functional, though the downstairs zone isn’t calling to the unit and the customer’s gas is out so we cannot run the heat. I told him I’d try to get back on Wednesday to complete the roofing but that I’d also look to have a tech come out to check the zoning. One zone damper is totally unaccessable and that appears to be the one not working. Need to finish paperwork and collect.
