Recent Review: First call: excellent job for $110 total cost, but no check of fan effectiveness (that was communicated to homeowner). Second call: At my request, installed two new exhaust ducts in attic with difficult access. Elapsed time on site-one hour; no electrical requirement; charge -$180 While working in an attic in summer is not fun, I feel that checking a fan for proper installation includes both electrical and ducting. There was no discussion of cost for the second call until the ducting was finished. I have not yet received a written bill but I assume I paid for an electricians hourly charge, plus travel time, plus two four inch ducts, plus tape. Given the circumstances, I think this is excessive.
