HVAC Mastery Bible: An All-in-One Guide to Heating, Ventilation, and Air Conditioning: From Installation to Repair | Integrate Smart Home Technologies and Understand Tax Credits Advantages

This would be good for someone who does not know anything about HVAC or the basics of how it works (eg: It’s meant to heat and cool). It’s written more like a novel than a textbook.If you’re looking for technical info, pass on this book, it’s not a mastery bible at all. If you’re looking for a basic explanation of an HVAC system, and really know nothing about it, this may work for you.

Little actual useful information on hvac systems and goes on about cyber security... ugh...?

This is superficial. Neither Mastery or bible. I would do better doing a five minute search on the internet.He goes on and on about the whole thing being a symphony.Oh, and clean your filters.
