WF, thank you for the prompt response to my post as well as the others.
I spoke to my dealer today (a WF authorized contractor) and he stated that they are contractually bound to WF to accept the labor charge paid by WF and not pass on any additional labor charges to the customer. This is different than what I'm reading in your most recent post.
From past direct experience and knowledge of his reputation in the area, I know my contractor to be an honest and reliable person so it puzzles me as to the contradiction between what he told me and what I'm reading here.
I've emailed him and am awaiting his reply. Any comments you would care to make would also be appreciated.
I'm looking at installing an Envision system and am excited about the prospect.
