Commercial Comfort is a full service, design-build HVAC contractor in Northwest Ohio. Since our founding in 1997, Commercial Comfort Systems has an excellent track record on projects large or small. In 2004, Commercial Comfort Systems began fabricating the Kingspan KoolDuct System and has become one of the largest suppliers of fabricated KoolDuct. By embracing this advanced and innovative system, we have been able to provide customers with higher R-values and lower air leakage than they would receive with traditional metal ductwork.
