I am so disappointed. Got word from the Broan dealer who did all the testing, measuring, and load calculation at my home on Tuesday. Due to circumstances beyond his control related to prior commitments, he will not be able to commit to doing the work for me at this time. As a result, he has declined to provide a proposal (i.e. estimate $$$).
Boohoo. Now looking for another reputable Broan dealer in Brevard County, FL. Wish me luck!
