Thanks you for the manual. I do not know if the answer I typed previously got to you.
Pipe to airhandler is cold. Low air flow from vents, with no difference between auto and fan setting.
copper tube running up side of indoor unit that is not covered is cold
the larger pipe that is covered in insulation does not feel cold to the touch.
there is a control on the outside of the duct. It has a large handle currently pointed straight down and a set screw. Currently this is not in the labeled "ideal position" so they are testing it now.
There is not enough air flow to rotate the damper in the duct against the weight on the arm as previously set, and forcing it open does not make a noticeble change in air flow to the vents.
insulated does not feel cold. Bare copper feels cold and has condensate on it. . Filter is not new, but does not look terrible.
where is the circuit board? not pictured in manual.
we have opened the damper handle to "ideal" with tape and remived filter temporarily to see if that improves things.
how do you get to the inside of the outdoor unit. He is having to access in the dark at this point.
at this point they are going to wait until morning and call someone there.
