The Air Conditioning Contractors of America (ACCA) is congratulating two longtime industry leaders and ACCA members, John Sedine and David Grosse, on their recent appointments to International Code Council (ICC) Code Development Committees (CDC) for the 2030 code change cycle.

Sedine has been appointed to the International Residential Code (IRC) Mechanical – Plumbing Code (M – P) CDC, while Grosse has been appointed to the International Mechanical Code (IMC) CDC. Their participation will bring HVAC contractor experience and technical expertise to the development of future model codes.  Both are voting members representing ACCA.

Sedine, consulting engineer with Engineered Heating & Cooling in Cedar Springs, Michigan, has more than 40 years of HVAC industry experience. A past chairman of ACCA, Sedine has served on numerous committees and contributed to the development of ACCA’s technical manuals and ANSI standards. He also served eight years on Michigan’s Board of Mechanical Rules.

Grosse is president of First Service, a mechanical contracting company in Midland, Texas, and co-founder and principal of Innovative Service Alliance. He began his HVAC career as a service technician and has held leadership roles in mechanical contracting for decades, including service on the Texas Air Conditioning Contractors Association (TACCA) board and executive committee.

The appointments provide opportunities for experienced contractor perspectives to inform proposed changes to the IRC and IMC as the 2030 code development cycle moves forward. The first round of hearings on submitted proposals will take place April 2027. 

Code change proposals can be submitted to ACCA’s manager of codes at [email protected].
