I am in the middle of massive home remodeling using a local general contractor. I had little control over the HVAC subcontractor selected. Removed two older hvac units, and are in the process of installing a 5-ton Bryant Evolution 16 SEER Heat PumP AC with four zones (2 upstairs and 2 down) and the Bryant EAC. All of the ductwork is being replaced also.
I have a million questions concerning the quality of the install (see sentence # 2 above), but here are the top two questions:
1. When I came home from Thanksgiving vacation, I found the new unit installed and the access panel open. I noticed "damage" to the fins on the expansion coil, but I do not know if this is typical or significant--or if I should raise a stink about it. Photo below.
2. Most of the ductwork is flex (see sentence #2 above). The HVAC isntallers used the same metal straps to hang the flex that they used to hang the hard pipe. I feel certain the metal straps will quickly cut the insulation on both the hard pipe and the flex, and eventually the flex duct inner liner also. Also it appears the flex duct is being crushed by the straps. There are several dozen similar spots, but I have attached a picture of one of the worst cases below. Should I raise a stink about this also? Photo below.
