### Overview

The only text that takes basic math concepts and applies them specifically to HVAC! This unique text covers the entire range of mathematical problems and subjects encountered by HVAC technicians in real-world situations. With practice problems, a review unit, and three review tests, students can easily assimilate the material presented and visualize its use in the field. A glossary defines terms specific to HVAC, while conversion charts present critical field information at a glance. This book works well as a math text all by itself, or in conjunction with a general math text. An instructor's guide includes two achievement review tests with answer keys, as well as answer keys to problems in the book.

### Features and Benefits

• contains new application problems involving the latest recycling, recovery, and reclaim techniques
• numerous figures ease learning by providing a visualization of the problem presented
• conversion charts present critical formulas and mathematical information at a glance
• glossary familiarizes users with important HVAC terms
