Most of the work technicians routinely perform is in maintaining existing equipment as opposed to installing new systems. The procedures and visual observation conditions presented in this title will enable technicians to perform their tasks more effectively. By knowing how the equipment is designed, built, and how the materials behave over time, they will be better able to execute a maintenance program extending equipment life and reducing unplanned malfunctions. This book's emphasis is on implementing these actions correctly and in a timely basis so that equipment experiences an increase in "life expectancy," reliability, more efficient energy performance, and a reduction in the possibility of future failures and liability. While the main focus of this work is on equipment installed in residential homes, the procedures detailed certainly apply to larger commercial heating equipment as well. The Sheet Metal/HVAC Pro Calc is a versatile calculator that enables tradesmen to calculate complex problems with dedicated key functions that are labeled in standard industry terms. The calculator has other advanced built-in construction-math functions to enable HVAC and sheet metal tradesmen to do their work alongside other trades. In addition to the built-in functions, this calculator can handle order of operation, perform square, cube, square root, and cube root calculations, determine ArcK constant for convenient Arc length solutions, and has an offset functions for "S-shaped" bends in ductwork. It can also help solve the layout for wrapper length, centerline radius, and the angle. It works as a regular calculator with typical symbols.
Together, Heating Systems Troubleshooting & Repair and the Sheet Metal/HVAC Pro Calculator are the perfect combination resource, providing instant access to metrics and measurements with the flip of a page and press of a button. This incredible set is a must-have for students and professionals in the HVAC field.
