Riassunto

You can do the arithmetic. Can you turn a gauge reading into the right next move?

Textbook of Math for HVACR 2026-2027 is built for HVACR apprentices and service technicians who need trade math to work the way the job actually works: a reading comes in off a gauge, a tape measure, or a nameplate, and a decision has to come out the other end. This book covers the full span of math an HVACR technician actually uses — whole numbers through algebra and trigonometry, electrical calculations, load calculations, duct sizing, psychrometrics, refrigeration-cycle math, piping and fan laws, and the cost and efficiency math a finished job still needs — and every topic is organized around Featuring The Field-Reading Calculation Pathway, a repeatable five-step sequence that turns any field reading into a confident decision: Read the Field Value, Convert to Working Units, Apply the Governing Relationship, Check Reasonableness, Decide the Next Action. Once a reader has walked that sequence through a few dozen different calculations, the Pathway itself becomes the transferable skill, ready for whatever new formula the trade presents next.

Inside, You Will Find:

• Fourteen chapters covering the complete HVACR applied-math curriculum, from foundational arithmetic through refrigeration-charge and fan-law calculations
• Mandatory Step-by-Step worked examples for every calculation type, never a bare formula with no explanation
• Real, natively typeset mathematical notation — true fractions, exponents, and radicals — the same way any professional engineering or trade textbook presents a formula
• KEY EQUATION callout blocks for every governing formula a technician needs to recognize and recall on the job
• The Field-Reading Calculation Pathway threaded through every chapter, plus The Field-Reading Calculation Index at the back of the book, cross-referencing every Pathway instance by field task for fast lookup under time pressure
• Full coverage of electrical calculations, heat-loss and heat-gain load calculations, duct sizing and static pressure, psychrometrics, refrigerant charge, piping and fan laws, and SEER2/EER2/COP efficiency metrics and job costing
• A Trade/Apprenticeship register that speaks like a working technician, not a lecture hall

Keep it on the bench, in the truck, or next to the apprenticeship coursework — this is the math reference built to go from a field reading to a field decision, every time.
