Frequently Asked Questions (FAQ)

What is the best HVAC system for the money?

In the age of Google and Siri, the library may seem a little old fashioned. And while it’s not a cool choice for enjoyable date nights, it’s an important option for those in search of knowledge. For our modern age of information, the good old library is still a great place to go hunting for books and information.

What is the most reliable HVAC brand?

A brand doesn’t matter. When purchasing a home heating and cooling system, what really matters is the quality of the system, not the brand. There are some great brands like Trane, Carrier, and Bryant out there that have great support and service, but all these companies buy their parts from the same handful of manufacturers.

Because these parts are interchangeable, the quality is the same. No matter who the manufacturer is, if the compressor is made by Ingersoll Rand, the lines are made by Saint Gobain, the coils came from Johnson Electric, you are going to get equal quality.

How difficult is HVAC Training?

It is very important to understand that training is the most expensive part of HVAC and will also cost you a lot of money. If you prefer to learn on your own, you have two options: self-study books and online courses. You can always find a book for any type of HVAC technology and read through it yourself.

You will receive the information you need but will be deprived from the personal guides or instructors that are important in completing your journey. Online courses can help you avoid spending big bucks on training but they lack the personal information that is needed.

A combination of training and books that also contains some personal instruction can help you beat the costs of going to an accredited school. The school training will be a lot faster and cheaper but it will require money, time, and effort to complete the training.

What classes do I need for HVAC?

In most cases, it is wise to find a program with a hands-on approach to teaching you how to become an HVAC Technician. Some programs teach you how to operate the controls after studying the theory behind them, others teach you how to do it from a mechanical standpoint, and still others provide you with the basic technical knowledge of how everything works.

However, nearly all HVAC programs require that you take some of the following courses:

  • Mechanical Drafting
  • Refrigeration
  • Analog and Digital Controls
  • Basic Electronics
  • Basic Electronics (A lot of programs have this as an elective rather than a required course)
  • Typical Curriculum for an HVAC Technician Program
  • Introduction to Drafting
  • Refrigeration I
  • Refrigeration II
  • Basic Electronics
  • Communications
  • Analog Controls
  • Digital Controls
  • Basic Mechanical
  • Buildings Construction


You definitely don’t need anything more than this book to start learning about HVAC, but if you’re looking for a more detailed guide, we suggest online HVAC training courses. If you want to build or repair HVAC equipment with confidence then you’ll need to have a basic understanding of how they work. With this understanding, you can troubleshoot problems and learn the various codes that relate to the industry.
