HVAC

My discipline since 1975 has been Commercial/industrial HVAC. Of course there is a sufficient amount of residential experience as well. I lived and worked in Colorado for 25+ years and am fully qualified in Gas, Oil,LP, Nat. I’m new to the home inspection trade…a year come may. Thank you Michael Bitterman of SNS home inspections.
My question? Do I have to take the whole Advanced HVAC course for my 4 point certification? Or, can I just go take the exam?
