The tech who gave me the estimate mentioned that he'd install a Rheem condenser. Also, now that I think about it, he didn't say that he would "remove and replace" the new ductwork that the original HVAC tech had installed.....he said that he'd "reinstall" this ductwork which leads me to believe that his intention may be to just "fix the existing spider duct". I will need to clarify this with him. My husband and I have both examined the existing (brand new) spider duct and we did see 2 separate areas with very sharp bends in the ducts and the appearance of some crushing in both of those areas.....otherwise, the rest of the spider duct appears to be intact and well placed with no signs of leaks, tears or crushing.
You've supplied me with some very useful information and I truly appreciate it. Thanks Phil.
