The Modern HVAC Technician’s Guide: Field Manual

Written for HVAC technicians tired of guesswork and repeat repairs, and homeowners fed up with relying entirely on others to decide if repairs are needed or justified. Instead of more textbook theory, this field manual bridges the gap between theoretical knowledge and hands-on troubleshooting. It features a four-step diagnostic framework separating root-cause analysis from part replacement, plus practical installation standards for piping, ductwork and electrical work. Coverage includes full refrigeration cycle diagnostics (superheat, subcooling, pressure readings), furnace startup sequences, heat pump defrost faults and intermittent electrical failure troubleshooting. After reading, you gain more than information: a consistent, repeatable process for on-site service or understanding your home system’s operation.
