I sent an angry email to customer service. I bought it at the end of September but didn't get everything together to assemble until Friday. Yeah, I'd heard to stay away from PTAC too, which I thought I had until this thing showed up. Went back to the site and saw "Nope, I inadvertently ordered the wrong one." "Oh well," I thought, "it looks to be made with quality materials. Besides, how badly can you screw up a BCG?" Pretty badly as it turns out! PSA=good. PTAC=POS.
