Best HVAC Books & Training Guides

These textbooks will help you learn about the AC and refrigeration industry.

One of the first things you learn about in HVAC technician training or school is that it is your responsibility to stay up to date on the industry, technologies, and training. Once you graduate, you are on your own.

The smart HVAC tech will work just as hard at maintaining his or her level of knowledge after schooling ends as they did in acquiring it. One of the best methods is to read and own HVAC books and training guides. This article will explain why you should have your own library of HVAC books and which ones you need to start your collection with.

Staying Updated on the Latest Advancement in the HVAC Industry

The HVAC industry isn’t sedentary. It is an ever-evolving and changing landscape that requires top-notch techs to offer value to their customers. The customer expects the tech to know what they are doing and dealing with. Books will help you and your techs stay on top of the changes in the industry.

HVAC-focused books are great to have. They are portable, easy to keep around for reference, and you can toss them in your truck to take to the job site in case you need to look up something on the spot.

Selecting Quality HVAC Books

How do you know which books to choose? You can always ask your neighbor, but they may be clueless. Instead, you need to decide If the book you are looking at is worthy of making your shelves at home. Here are things to consider before you buy.

HVAC Tech Level

One thing to consider is your current HVAC tech level. Are you a seasoned pro looking to stay up on the new gadgets? Or are you a tech still in training looking for a head up over the competition?

Entry Level HVAC Tech

Entry-level techs will do good to keep the studying habits from training going long after they have their certifications. Since the studying habits are still fresh, maintaining that level of study will only do good.

Entry-level techs should look for books that are refreshers of what they just learned as well as looking for books that offer experiences and knowledge for the next level of their careers.

Advanced/Experienced HVAC Engineer

The advanced technician and experienced engineer will need more. These books should focus more on the future. Books that explain and cover emerging technologies, procedures, and tools. The seasoned professional should be apprised of what is currently being taught in the classroom and needs to have the right books to stay on top of those things.

These techs need to focus on finding the books that cover what is coming in the world of HVAC technologies and procedures. They should also look for newer books that have emerging ideas for their trade.

Preparing for HVAC Exam

If you are an HVAC tech in a position of having to prepare for a certification or exam, you will need books that align with your current course of study. Many books will cover the topic in different ways. One of them (or more) may help your understanding of a procedure or using a tool that you didn’t quite understand from your instructor or reading the classroom books.

It never hurts to have more study materials that cover topics in various ways. Never stop learning.

Bar Code Number (ISBN)

The ISBN is a number assigned to every published book since 1970. It is a unique identifier for a particular book using a 13-digit numerical code. Before 1970 the SBN ( a 9-digit code) was used for commercial books. The ISBN number can be either 10 digits or 13. The more published books over the years have created the need for the 13-digit number we see most often today.

The bar code number is a quick way to identify the age of a book. If the book has an ISBN, it is a modern book, if it is an SBN, it is older, and if there isn’t a code at all, the book is considered antique and is most likely a part of the public domain.

Hardcover vs. Paperback

Hardcover books are generally more expensive and harder to carry around than their paperback counterparts. Which one you prefer is a complete personal judgment call. However, paperbacks won’t last as long if they are continuously used.

If you plan to take your books with you, choose paperback. If you keep them in the home study to use when you aren’t in the field, hardcover may be more practical.

Electronic vs. Regular Books

Aside from hardcover and paperback, you also have the opportunity to purchase and download eBooks. Amazon Kindle is a free reader that can be used on almost any mobile device. Once the books are downloaded to your device, you won’t need to connect to the internet to read them.

Electronic books are ideal for use in the field to gain an advantage over the techs that need to leave to get more information or call someone else to help out.

Language Availability

If English isn’t your first language, you will want to find books in your native language. While this can prove difficult for some titles, more and more electronic books are being translated in various languages all the time.

It never hurts to make things easier on yourself. If you need to read in another language to understand a process thoroughly, then books may be the best method of doing so.

Date Published

Since the HVAC industry is ever-changing, it is a good idea to stay with current books. You can check the publication date to find out how old the book is. While the newer books will be the most up to date, this doesn’t mean that older books aren’t worth a purchase.

Older techniques are still used today and, in many situations, can be the difference between completing the job and having to start a different route. While technologies change, some procedures and practices are timeless.

Price Range

Finally, you will want to make a note of the price and attempt to not go over your budget. One of the good things about books is that they don’t change. If you can’t easily afford the book today, it will still be there tomorrow.

Often waiting a few days or weeks can see a price drop or a special of some sort to save you a bit of money. Be on the lookout for coupons, deals, and specials to save even more.

Isn’t all of the information available for free online?

However, HVAC specific books are more inclusive, show you exactly what you need to know, and you don’t have to go through five or six different websites to find the specific information you need.

How important is it for me to learn about refrigeration systems?

If you want to become a certified HVAC technician, it is the most important aspect of your job. Just like a surgeon needs to learn about the biology of the human body, the HVAC tech needs to learn about the life-force of the HVAC system.

Is it really worth taking the NATE/ICE and other exams?

Taking the NATE/ICE exams are not essential to becoming an HVAC technician. However, they are essential for becoming the best HVAC technician. By taking and passing the exams, you let employers know you are well prepared for any situation and do what it takes to stay on top of the game.

Where can I download free air conditioning eBooks?

Free HVAC book downloads are rare and hard to come by. A lot of the free books are only offers for getting your personal information to sell you more items and fill your email inbox. In most cases, you won’t even get the book you were after, or it will be a partial print out of the PDF version. If you do search for free HVAC training books for download, be wary of off-site access and other forms of online security issues.

Can I get my HVAC certification online?

You can study and practice for the exam online. However, for the EPA 608 certification, you will need to take the test by a certified proctor. This isn’t a common practice to do online as you have to be able to prove you are the one taking the exam and to help prevent cheating.

Is EPA certification the same as HVAC certification?

No. EPA certification is a requirement to work with, dispose of, and handle refrigerant. HVAC technician certification is not required by federal law, but many employers or state laws do require it for employment. You can become an HVAC technician by title without a certification, but you cannot purchase or work with refrigerant systems in the field without the EPA certification.

How can I get a Universal HVAC certification?

To get the Universal classification of the EPA 608 certification, you need to take and pass all three sections of the exam. If you fail any of the three Type exams, you will get EPA 608 certified for the Type exams you do pass, but you cannot be universal without passing all three.


Staying up to date on all things HVAC is a crucial step in maintaining and advancing your HVAC technician career. One of the best methods for doing so is to purchase books that keep you updated and informed.

There are a lot of choices out there, and the decision process can be complicated.
