  • O&K Truck Repairs Ltd. 350 Grand Island Boulevard Tonawanda, NY, 14150 (map)

Training: 8:00 a.m.—4:30 p.m. EST

This in-person A/C system training course covers proper procedures for recovering, evacuating, recharging, and recycling A/C system refrigerant beyond minimum certification requirements. This course also covers diagnostics and repair of air conditioning systems in today’s heavy-duty vehicles. Build skills to diagnose and repair problems with climate controls, electronic components, computers/BCMs, and related electrical systems. Modern A/C issues can be difficult to diagnose with techniques used for older R-12/R-134a systems, so don't miss the useful A/C repair strategies in this course for the electronic systems found on many vehicles today.

This course includes books, safety glasses and MACS certification in R134a and R1234yf. 

Instructors: Swede Oun 🡢 and Jerry "G" Truglia 🡢 

Note: Safety glasses must be worn during all hands-on training in this course.
