COLUMBIA, S.C. - You could say that duct diagnostics is a hot topic these days. People who perform such diagnostics with high-tech tools have stepped forward with great fervor and in strong support of using professional tools rather than homemade.
One such company, National Comfort Institute (NCI), headquartered in Sheffield Lake, Ohio, gave a presentation at a seminar held by the South Carolina Association of Heating and Air Conditioning Contractors (SCAHACC). NCI President Rob Falke spoke on "Effective Duct System Diagnostics." The company markets its duct diagnostic training programs to HVAC contractors.
