MAKE BETTER REPAIR DECISIONS.When an air conditioner stops cooling, a compressor overheats, or a heat pump fails to perform as expected, the visible symptom does not always reveal the real problem. Guessing at the cause can lead to unnecessary part replacements, incorrect refrigerant adjustments, wasted time, and repeat service calls.HVAC Technician's Troubleshooting & Diagnostics Field Manual by Blake R. Harlan provides a practical, systematic approach to diagnosing residential and light-commercial HVAC systems. Learn how to interpret measurements, investigate possible causes, identify root problems, and verify repairs using a structured troubleshooting process.WHAT YOU WILL LEARNRefrigeration fundamentals: Understand the vapor-compression cycle, major components, pressure-temperature relationships, and heat transfer.Superheat and subcooling: Learn how to calculate and interpret measurements, recognize abnormal patterns, and evaluate refrigerant system performance.Refrigerant charging and leak diagnosis: Explore undercharge and overcharge symptoms, refrigerant restrictions, approved charging methods, and charge verification.Airflow and system performance: Investigate dirty filters, blocked coils, duct restrictions, blower problems, static pressure, and temperature measurements.Electrical and compressor diagnostics: Examine capacitors, contactors, relays, motors, wiring, sensors, control circuits, and compressor performance.Heat pump troubleshooting: Understand reversing-valve problems, defrost failures, heating performance, and changing operating conditions.Inverter and variable-capacity systems: Learn about compressor modulation, electronic expansion valves, sensors, communication faults, and manufacturer test procedures.A1 and A2L refrigerant safety: Explore refrigerant classifications, R-410A, R-32, R-454B, detection systems, compatible tools, and essential service precautions.PRACTICAL TOOLS FOR REAL-WORLD DIAGNOSTICSThis field manual goes beyond explaining individual components. It helps you connect symptoms with measurements and use additional tests to distinguish between competing explanations.Inside, you will find: Step-by-step HVAC service-call workflows.Worked examples and diagnostic calculations.Refrigerant pressure and temperature reference material.Symptom-to-cause diagnostic matrices.Airflow, static-pressure, and electrical testing worksheets.Troubleshooting flowcharts and root-cause decision trees.Refrigerant charging and system-verification checklists.Practical case studies involving airflow faults, refrigerant leaks, restricted components, compressor overheating, electrical problems, heat pumps, and inverter-driven equipment.A service-call diagnostic report template for documenting findings and repairs.WHO SHOULD READ THIS BOOK?Whether you are an HVAC technician, apprentice, technical student, or developing service professional, this manual provides a useful foundation for strengthening your diagnostic knowledge. Experienced technicians can also consult its worksheets, decision trees, and case studies when investigating unfamiliar faults.The goal is not simply to recognize a symptom. It is to understand what the evidence means, determine which test to perform next, and confirm the underlying cause before taking corrective action.Build your HVAC troubleshooting skills, improve your understanding of refrigeration diagnostics, and develop a more disciplined approach to service work.Add HVAC Technician's Troubleshooting & Diagnostics Field Manual to your technical reference library today.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/816/610/9798166107886_b.jpg", "price_data" : { "retail_price" : "15.99", "online_price" : "15.99", "our_price" : "15.99", "club_price" : "15.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
