For the price people pay for new equipment, that installation looks terrible. First...the pvc line running down to the floor has two couplings...unneccessary. Second, no cap on the tee. Third, I don't see a vent after the p-trap. Third, where is the secondary drain line? Fourth, that line set looks like crap. Fifth, I wouldn't use tie straps. When tightened too much...the copper insulation loses it's insulating properties and starts sweating at those points...which looks like about eight different areas...as they all look overtightened. Plus they used white straps. I used (black) straps for a little while until this problem arouse. I wonder if the horizontal drip tray was removed before converting this to a vertical downflow. What about the factory installed baffle?...has it been changed out? And, if this is a four or five ton...have the water diverters been installed? Does this unit go through the floor? Doesn't look like it since I see cement blocks underneath the supply plenum and flex coming off the plenum. Supposing there is no duct work underneath the floor...why is this a vertical downflow? One more thing...why do four out of five of those screws looks different than the other one? Poor workmanship.
