In this comprehensive HVAC training video, we explore why compressors fail and provide expert guidance on diagnosis techniques, replacement procedures, and prevention strategies to avoid costly callbacks.
Key Topics Covered:
Main causes of compressor failures
Acid contamination and why "ACID-AWAY" products don't work
Proper acid cleanup procedures with filter driers
Checking refrigerant charge and standing pressure
Oil return issues and lubrication problems
Floodback vs. starvation conditions
Flooded starts and crankcase heaters
Hard start kits: when they help and when they hurt
Essential electrical components for replacement during changeout
Contamination from copper shavings, moisture, and particulates
Long line set considerations and manufacturer requirements
Critical Diagnosis Steps:
Static pressure testing
Acid testing procedures
Weighing recovered refrigerant
Inspecting electrical connections
Evaluating airflow and filter conditions
Wire damage and high voltage issues
Learn the proper prevention methods and replacement best practices to ensure compressor longevity. Master the diagnosis of failed compressors and understand what truly causes them to fail.
