I found the technicians disdain for my Lenox furnace somewhat off putting. Although my unit is older, I did not see the need to hear constant complaints regarding how the circuit board was configured or attached to the unit. His aggressive nature in taking the circuit board off the unit made me question if the damage was done previously or just in him taking it off to inspect it. Obviously, the resulting prognosis was to replace the circuit board of course, oh and just disregard that I practically ripped it off the unit to conclude this point.
