EPA 608 Practice Comments & Reviews 2026
APP KEEPS SAYING I MISSED QUESTIONS THAT ARE CORRECT. Its kind of frustrating that i select one answer and then when i finish and check which ones i missed the app says i chose a different answer. please fix this
This is the one. Used this app alone to study for the exam and passed with 90+% on all sections.
Good info/freezes. If you lock your phone or it turns sideways the app freezes, for something that cost $9 it’s kinda insane
Good app. App serves its purpose. To the developer, it would be extremely helpful to have the option to shuffle the questions.
Great. Great so far. Along with the prep manual we got in class, I feel very confident going into all parts of the exam. Only minor complaint is that the question choices could be lower to prevent exiting a started practice exam.
YES!. If it wasn’t for this app I would have never got my Certification! I don’t have access to a computer (I know it’s 2018 and everyone has one) so this app really helped me study while I was at work, family house, friends house, and my favorite spot to study in the restroom. LOL thanks a lot!
Practice test. 5/5 definitely worth it. I recommend it to anyone who is trying to get their EPA 608
Good questions but the app is filled with bugs. Be prepared to not be able to go the next question or get to the last question then the app will crash leaving you not knowing what you got wrong and what you got right. Tilting the phone causes the app to freeze as well
Great way to prep for the test. I have been using this for days and reading the epa prep manual. This app has been helping me retain the information. I have noticed one question on the type 3 study mode has a wrong answer. Question 85 states 25 inches is correct but the epa study guide and web site state it should be 25mm.
not worth 10 bills. Imma keep it short and simple I don’t even write reviews but this app is not worth ten dollars way too buggy and is not even an officially certified epa app I’d say its worth $0.99 thats a good price
Unstable. Great questions but the exams keep resetting and you have to start over. Never allowing you to review your questions. iPad Pro (11-inch) (2nd generation) - 13.6.1
Great app. I love this app and it helped me so much on my studying and I passed the first time I took the took the test. I just wished you have a book marked to make it easy to mark where you stopped the time time to continue study instead of going to the beginning again other than that I highly recommend
Is the test up to date as of July 2020. Great app just don’t know if it’s still up to date
Please UPDATE. The questions are great and it’s really helping me study for my test. My one complaint is in reference to the questions that other people have pointed out having the wrong answers in their reviews. The questions haven’t been fixed, and their reviews are from over a year ago……
Great app!. Passed this test the first time, all 4 parts. Just fix the null question bugs.
Great!. This app helped me pass the second time. This helped me more than the epa prep handbook. Practice questions are exactly how they are on the real test.
Good but not great. The questions on the app are right on with what I learned would be on the test but for some reason when taking practice tests and reviewing the answers after I realized that it was marking answers wrong saying I picked a different answer when I know I picked the correct answer. So just keep on that, but other then that it’s good
Great App. Just took the exam and all I can say a lot of the questions on this app were in the exam I took.
How do I even know you guys know your stuff. Which type of refrigerant is most harmful to the stratosphere ozone? A. Ref. Containing bromine B. Ref. Containing chlorine C. Containing hydrogen D. Containing Florine You might think B. But the app says it’s a which it is not. So how do I know all the other questions are right.
Passed. Passed all 4 tests first try in less then an hour.
App 608 review. I would rate a 5 but i have some issues. I really like the app but when taking the practice test I can not go back at any point. When the test are over and questions are reviewed I have to completely close the app and reopen to get to the next section of test. I also can not see all of the answer if it is a long question in the review portion. It is a good tool and I definitely like the mobility of it on my phone but please fix these issues or tell me how on my end.
Can’t see!. Please format the app correctly. I can’t see or scroll to the bottom of the app. Other than that the app works as intended.
Testing. The practice test they provide on the testing website has maybe 30% of the questions this app has 100% of the questions on the test I can’t push this out there enough get this app it’s so worth it
Great Practice Tests and study options!. This app is definitely what got me through the test to get my AC certification. Spent 6 total hours going through the universal and type 1 questions and aced those two sections when it came test time! Would definitely like it updated to follow more in line with actual wording and add some questions that weren’t on the modern test. Well worth the $10. Please keep updating this developers!
Wish it explained better. Why doesn’t it explain why you got a question wrong? And is this test up to date with all the new EPA regulations?
DO NOT BUY, Get the free version instead. THIS IS OUTDATED. If you go to the official esco website, their practice test is way different from this. I just took the epa, and this app is seriously outdated. About 90% of the questions on this app ARE NOT on the actual epa. Yet they still want to charge you ten dollars. This is extremely lazy and unprofessional on their end.
Not working. I installed the app 3 times and it doesn’t work, iPhone xs max , ios 13 !!!
Need help. I’m having problems just downloaded the app and everything question and test is saying Undefined
Passed my epa 608 exam. This app is legit gold, i passed my epa exam with high schores 92,96,92,92 i seriously dont know how this app is not famous it is definitely worth the $10 very great information, i am literally shaking of excitement rn because i passed, thank you developers of this app for having almost every question match the epatest.com exam
App still has bugs. Hi developer I purchased this app 2 weeks ago and using it just few days from now. I can see somebody already mentioned about the questions being chosen different with my choice after finish the test. When I go back to review I can see that. PLEASE FIX ASAP. And if you can add bookmark questions, that will be great!
Answers are very similar to the ones on the test. The questions are very similar or the same to the ones on the EPA test. I recognized a lot of questions. With over 500 practice questions this is the gold standard for EPA practice tests. It’s definitely worth the price.
iOS 13. Doesn’t work with iOS 13. Can you please fix. Take epa in 3 weeks
5 stars. This app was extremely helpful. To future test takers leave nothing on the table. I’m taking a summer class and had 22 days to prepare. Started off on YouTube. Learn the refrigerant cycle first, then print off the pressure temperature chart and learn how to answer the questions on the app while looking at the chart. The proctored test is timed 120 minutes. I’m now universal on first try scored high 80s and 90s on all sections good luck
Thank you and thanks for helping. 🙏🙏🙏🙏
Good study questions, poorly optimized app. While the study questions are good, the app itself could use some help. It is not optimized to work with newer iPhones with the “dynamic island”… the back buttons barely work and need to tapped multiple times in different areas for it to be registered as a click. Some of the text is also hidden behind the “dynamic island” making it unreadable.
Perfect test prep. Anyone looking for an edge on taking any level of the epa 608 needs this. I wasted money on the book, on study plans and my adhd just can’t lol. This honestly made the test a breeze, I aced it first time, thanks to this app. It’s simple which makes it perfect, easy to follow and if you get distracted easily like I do this is the app for you. The minimalistic look is what kept me from getting distracted. Use the study part to become familiarized with the questions on each section. And then use the practice tests as a way to hammer in the answers. Before you take your test, do a final practice test on each section individually. Doing that helped me, hope it helps someone else with a similar squirrel brain.
Worth every penny!!. I purchased this app a few weeks ago. I went through every practice question and did all the practice tests 2-3 a week. Then, I Would read and review the ESCO literature and highlight all the familiar questions from the app. I ended up highlighting 90% of the book. The best part was that it wasn’t just yellow lines on a page, but the info was actually retained. I received 100% core, 100% type1, 92% type2, 92% type 3. The app had current information, and the exam questions were recognizable. It is Worth every penny!!!
Best App ever used. I don’t usually write reviews, but I just got done taking my EPA 608 universal and PASSED. This app has the EXACT questions that are on the test and that is no joke! Normally they are worded different, nope, exactly. I literally studied this app the night before, last night, just ran through the practice test four or five times each and took my exam today and passed. 6 stars if I could. Great work, worth every penny, cause now I don’t need to pay for another test.
Mostly good. Can you offer landscape mode/view for iPads?
Incorrect info. During my first practice I found this question: Which of the following refrigerant has a GWP of “1”? And 4 answers provided are: R-22, R-134a, R-410a, R1234ze and according to my current EPA 608 Manual (9th Edition V2, page 15) non of them has GWP of “1”
Not worth it. Does not function properly
Best money ever spent on app. I pay for this app referred to me by my classmates, i put on study mode and do the test practice for two weeks before I went for my Esco 608 and I passed Core, tape 1,2,3 now I’m universal thanks to the developer I really appreciate this app
Everyone that used this passed. I recommended this to my fellow students. Everyone that used it passed. My average score was 92%.
Best test prep. All the Questions are as they are in the exam.
Question. Is the question and answer the Same as the actual test? And when I take the test do I have to take the core or just type 1 2 3? Do I really have to study the core part to pass?
Undefined. There are pages in the practice quiz where the questions and answer show up as undefined. Please fix
Worth it. English is my second language and this app helped a lot and I passed all the types. Thank you.
Got my Universal. I used this app to help me study . It worked great I passed on the first try with an average score of 80. Also this app worked great to help me focus on the Esco study guide. If you are like me the study guide is BORING.
Good app for review. Question 3 of core study is wrong, the quest asks which synthetic oil is used for hfc systems and hcfc systems retrofitted to hfc. The correct answer is polyolester, the app lists alkylbenzene as the answer but if you look at all other texts and sources they say that oil is only used on hcfc refrigerants
AWESOME. I GOT UNIVERSAL FROM THIS APP, MAJORITY OF THE QUESTIONS ARE ON THE TEST. 10/10 MUCH APPRECIATED.

Glitchy. I really like the app and there is a lot of good information but I’m having a lot of issues with the practice tests. Every time I take a test, somehow my answers change after I move on to the next question. I just took type III and wrote down all my answers as I went. When I finished, I was given a 72/100. When I went back through all of the questions, I actually got 100/100. Every question that the app told me I answered incorrectly, I didn’t. Not sure what’s going on here but it happens every time that I take any practice test.
