AXIS Certified Professional Technicians exam — first attempt experience
Just sat for the AXIS CPT exam last Thursday and wanted to share what the experience was like since I couldn't find many detailed firsthand accounts when I was preparing. I work in industrial HVAC and my employer required the certification for a new service contract. I studied for about 5 weeks, around 90 minutes per day, mostly on lunch breaks and after work.
The exam is heavier on system diagnostics and fault isolation than I anticipated. I went in expecting maybe 60% theory and 40% application questions but it felt closer to 45/55 in the other direction. The refrigerant handling section was straightforward — if you've got your EPA 608 that part's almost automatic. Electrical troubleshooting was where I had to slow down and think.
I scored 81% overall, which was good enough to pass. The thing that helped most was drawing out circuit diagrams by hand while reviewing the technical manuals. Something about writing it out instead of just reading made the fault sequence logic stick. Anyone else taking this soon — happy to answer questions about the format.
Mine was right around 2 hours 45 minutes with time to review. Don't rush through the diagnostic scenarios — read every option carefully. I almost talked myself out of a correct answer on two questions.
Thanks for posting this — I've got mine in 3 weeks and the diagnostic-heavy format is good to know. I've been spending too much time on the theory sections and should probably shift focus.
How long was the exam total? I've seen different numbers thrown around — some sources say 2.5 hours, others say 3. Want to know how to pace myself.
I took it in February. 81% is solid — the passing cutoff where I tested was 70% but I wouldn't want to cut it that close with this exam. Some of the fault isolation scenarios are legitimately tricky if you haven't seen that exact failure mode in the field.
The hand-drawing tip is real. I did the same thing with ladder diagrams and it made a difference.
Thanks for posting this -- I'm actually in the middle of prep right now and it's reassuring to hear a real account. I've been using a mix of the official study guide and some online practice questions, and I just hit 78% on a timed mock last night which felt decent but I know there's still ground to cover. If you haven't tried it yet, this free axis professional technicians video surveillance question set helped me a lot with the surveillance-specific sections that I wasn't confident about.
I'm planning to sit for it in about three weeks, assuming my scores stay consistent. Did you feel like the time pressure was the hardest part, or was it more the depth of the technical content?
