The amount of water condensation was more than I am used to seeing,but figure this may be normal for this type of system. Looks like I may simply need to put it under the hated refer to qualified contractor catagory.The only info afforded me was through a board member of the association of five buildings whom told me they replaced the outside unit at hers two weeks ago for 30 grand ,so I figure this may follow suit. This could be a consideration for my client if funds were drained. When I was there I thought the word was combiner as the compartment holds a blower and exchanger only. I love this job for these little puzzles.
