The company answered my urgent call and scheduled an appointment immediately after I explained my situation. The technician, Kyle, was absolutely fabulous. We had a sink which overflowed, pouring a river of water into the floor supply vent, through the basement ceiling vents, all the way down to the furnace unit. Ugh! Kyle was extremely thorough in evaluating the evidence of water damage, observing and documenting the debris that flowed down with the water (OY!), comparing the affected vents, ducts and trunk line to the unaffected ones, and making appropriate recommendations of remediation steps that should be taken now, as well as potential problems which we should be alert to in the future. I felt well-informed and confident after Kyle's inspection and instruction on these issues.
