Practical Problems in Mathematics for Heating and Cooling Technicians
Solve Practical Math Problems Commonly Faced By HVAC Technicians On The Job

By Russell B. DeVore - Fourth Edition

From basic arithmetic to using formulas, this fully updated edition applies essential practical math skills directly to the field of heating and cooling technology.

All math concepts use terminology specific to the HVAC-R trade to help technicians prepare for problems they will encounter on the job.

The entire range of mathematics problems used in the field are covered - from whole numbers, fractions, ratio and proportion, to percentages, measures, formulas, and trigonometry.

Useful practice opportunities in the book also help readers learn to write up estimates and bills.

Features:

• "Practice problems", "A Review Unit", and "Review Tests" enable readers to easily absorb the information and conceive of its use in the field
• A discussion of calculator use is supplemented with examples of how to use one to create estimates
• Realistic drawings and illustrations encourage understanding by providing a visualization of problems presented
• A comprehensive glossary defines terms specific to heating and cooling, while conversion charts present critical field information at a glance
• Serves as a math text on its own, as well as a supplement to a general math book
