Our company is a unique force within the Tri-State HVAC/R service industry. We are the successful merger of professionals from numerous mechanical powerhouses such as, Nationwide Mechanical Contractors Corp. and P & P Sheet Metal, Inc., both of which were dominant in the HVAC/R contracting business for over 42 years. Clean Air Quality Service, Inc., has been incorporated for over 15 years, primarily specializing in large commercial projects. However, we are very diversified in the HVAC/R field, also working in the industrial and residential areas. We perform 98% of the HVAC/R work with our own in-house staff, including pipefitting, sheet metal, technical service, systems layout, and temperature and operating controls
