These are real pages from the book. The table of contents is the full one: 6 parts and 60 topics.
It's 10 p.m., work boots still by the door, and a Type II practice question gives you a saturation pressure of 180 psia at 104 °F: medium or high pressure? Your gauges have read psig for years, and you hesitate.
The study guide gives the four classes in one sentence: under 45, 45 to 170, 170 to 355, above 355, all in psia, all at 104 °F. Four ranges and two conditions with nothing to see, so by the next night the numbers trade places.
In this book, the four classes are one drawing on one page: a single scale from vacuum to above 355 psia, each class in its own color, with psia and 104 °F printed on top. You see where each range ends.
The same goes for the three R's, the recovery cylinder, small appliances, the leak repair thresholds and the purge unit on a low-pressure chiller: each one has its own page.
180 psia lands in the high band, and you know why, without going back to the guide. Then the next question, and the one after that.
Before you study, Core, Type I, Type II, Type III and a final review: 64 pages, all illustrated
Think of it this way:
Two nights before the exam, a Type III practice question asks at what pressure the rupture disc on a low-pressure chiller opens.
You open the rupture disc page: the chiller drawn, the disc on the evaporator and one number in the box, 15 psig. On exam day you picture the drawing before you read the options.
Same with the recovery cylinder, the 5-pound small appliance limit, the 50-pound leak repair threshold, the purge unit and the nitrogen pressure test: each one on its own page.
EPA 608 Illustrated is 6 parts and 60 topics, all drawn, with a practice page closing each section and a mixed Universal practice at the end.
What you see drawn, you don't have to memorize.
You know which card you need and read every pressure unit without hesitating: how the exam works, Type I, II, III or Universal, the refrigeration cycle, high and low side, pressure and temperature, psig, psia, inches of Hg and microns.
Core stops being a wall of acronyms and dates: ozone and chlorine, CFC, HCFC, HFC and HFO, ODP vs. GWP, the Montreal Protocol, the venting prohibition, the AIM Act and A2L refrigerants, the three R's, recovery equipment and cylinders, evacuation, safety and shipping, with Core practice.
Type I comes down to a few numbers and two ways to recover: what counts as a small appliance, how much you must recover, passive recovery, piercing valves, identifying the refrigerant first, disposal and Type I practice.
The longest section, in the order you'd meet it on the job: medium, high and very high pressure, signs of a leak, the nitrogen pressure test, the 50 lb leak repair rule, verification tests and records, recovery, evacuation levels, exceptions, charging, oils and Type II practice.
The chiller that runs in a vacuum, explained from the drawing: the purge unit, the 15 psig rupture disc, leak testing, recovery, keeping the tubes from freezing, 25 mm Hg evacuation, charging, the machinery room and Type III practice.
The last days fit on a few pages: every number and date on one page, the pairs people mix up, how questions try to trip you, mixed Universal practice, the exam day checklist and getting your card.
At the end of the book: A practice page closing every section, a mixed Universal practice and every exam number on one page.
Multiple-choice questions for all four sections, in the same format as the real exam, with every answer explained so you know why, not just which letter.
The pairs people mix up most often (recover vs. recycle vs. reclaim, ODP vs. GWP, active vs. passive recovery, high- vs. low-pressure) side by side on printable one-page sheets for your last review.

PDF by email: We email you EPA 608 Illustrated as a PDF, together with the two free books. It's a single payment: no installments, no extra charges.
One topic per page, so twenty minutes after dinner is enough to finish one and actually keep it.
The book follows the exam order, Core to Type III, and the final review puts every number and date on one page for the last days.
Building maintenance, appliance repair or HVAC: you know the equipment and need the card. The book draws the rules behind what you already do, like nitrogen and never oxygen, or the 80% cylinder limit.

You pay once. No subscriptions.
Yes. It starts with how the exam works and the refrigeration cycle, and every topic fits on one page, so you can study in short sessions.
It's checked against epa.gov: Clean Air Act Section 608 and 40 CFR Part 82, Subpart F, plus the AIM Act rules for HFCs and A2L refrigerants in 40 CFR Part 84. The AIM Act pages are kept separate from the Section 608 rules, so you know which one the exam is asking about. What can't be verified there doesn't go in.
No. It's an independent study guide, not affiliated with or endorsed by the EPA or any EPA-approved certifying organization. It doesn't certify you: you take the exam with an EPA-approved certifying organization, which charges its own fee and issues your card. The book covers the federal Section 608 rules that every approved organization tests, Core through Type III.
No. It's study material for the exam. Working on refrigerant circuits is learned on the job, with your employer and your trade school.
No. They're written for this book, in the same multiple-choice format, with every answer explained.
As a PDF by email, sent to the address you enter at checkout. The 2 bonus books come the same way.
No. It's a one-time payment, no subscription. And if you're wondering why pay when there are free guides and videos: they give you the rules in paragraphs, each in a different order. Here every rule has its own drawn page, in exam order, the numbers sit in one box, and you can print it and keep it in the truck.
Yes. It's a PDF you can print at home or at a print shop and keep in the truck.
You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
No more rereading the study guide with nothing sticking.
The refrigeration cycle: you see it drawn and it clicks.
You walk into the exam knowing where every rule lives.
