  The fastest way to raise a practice test score is to stop re-studying what you already know and focus on what you keep getting wrong. This tutorial shows how to do that with the Mistakes and Bookmarks lists in HVAC Exam Master APP , a free-to-try EPA 608 and NATE practice app. The same method works with a paper notebook. How the two lists work Mistakes Bookmarks How questions get added Automatically, whenever you answer wrong Manually, when you tap the ☆ star How questions leave Automatically, when you answer correctly during review When you tap the star again Best for Things you got wrong Things you guessed on or want to remember Step 1: Practice normally, and star your guesses Work through a practice set as usual. Every time you're not sure of an answer, tap the star in the top-right corner of the question, even if your answer turns out to be right. A practice question with the bookmark star turned on This is the habit most people skip. A lucky guess is a mistake that hasn...

  HVAC has three very different kinds of credentials, and people mix them up all the time: EPA 608 certification , NATE certification , and state or local HVAC licenses . They're issued by different organizations and prove different things. Only some of them are required. Here's how they compare, and the order most techs get them in. The short version EPA 608 NATE State / local license Required? Yes, federally, to work with refrigerant No, it's voluntary Depends on your state or city Issued by EPA-approved certifying organizations North American Technician Excellence State or local licensing boards Proves You know refrigerant rules and safe handling You know how to install or service specific equipment You're legally allowed to do (or contract for) HVAC work in that area Tests on Regulations, recovery, leak repair, safety Core knowledge plus one equipment specialty Often codes (mechanical, fuel gas, electrical), trade knowledge, and sometimes business and law Expires? N...

  Most people who fail the EPA 608 didn't skip studying. They studied in a way that didn't prepare them for how the exam is actually graded, or for which questions actually show up. Here are seven common mistakes, and what to do instead. 1. Memorizing a practice test instead of learning the material Take the same free practice test five times and you'll eventually score 100%. But by then you're recognizing answers, not understanding them. The real exam draws from a different question pool, and small wording changes will throw you. Do this instead: practice with a large question bank, and after every question, read why the answer is right, even when you got it right. If you can't explain an answer in your own words, you don't know it yet. Practice question with a full explanation of why the answer is correct 2. Watching your average instead of each section The 608 grades each section separately, and you need 18 of 25 in each one. A 90% on Core and a 64% on Typ...

  If you're new to HVAC, "get your 608" is probably one of the first things you heard. And it probably came with a lot of questions nobody answered clearly. Here are straight answers to the 15 questions new techs ask most. The basics 1. What is EPA 608 certification? It's the federal certification required under Section 608 of the Clean Air Act for technicians who work on equipment containing refrigerant. It shows you know the rules for handling refrigerant safely and legally: recovery, leak repair, venting prohibitions, and safety. 2. Who needs it? Anyone who maintains, services, repairs, or disposes of equipment in a way that could release refrigerant into the atmosphere. In practice, that means almost every HVAC and refrigeration technician, plus appliance techs who work on sealed systems. You don't need it if your work never opens a refrigerant circuit. Examples include duct installation, sheet metal work, or thermostat work on systems you don't break int...
