Found drain log clogged for the second time. Cleared and flushed out drain line by sucking out drain from the outside, followed by running water down the drain as vacuum was pulling. Drain line is now clean and cleared. Removed water from emergency drain pan. Getting high static in the return and zero static in the supply. All filters are clean and could not see any other visible restrictions. Need to send smaller check back to inspect ductwork in attic to make sure there is no ducts that are collapsed.
