We did not purchase a product, however we had our hot water chimney flute inspected and discovered the chimney was completely closed. Eric Hartman did the inspection, and warned us of the danger of carbon monoxide escaping from the vent. He was very professional in the advice given. He turned off the hot water, and strongly recommended that we call a plumber ASAP. This inspection saved our lives. We recommend midtown because of the care, knowledge, and professionalism we experienced.
