What causes clogged in evaporator and condenser?

Compressor Noise When the Freon oil breaks down, it causes friction that flakes off bits of metal. The metal travels through the hard line and into the condenser, causing a blockage. With a heavy accumulation, the metal debris can travel further and block the expansion or orifice tube.

What are the signs of a clogged orifice tube?

Symptoms of a Bad or Failing Expansion Valve (Orifice Tube)

  • AC system performing worse than usual and blowing warm air. One of the first symptoms of a problem with the AC expansion valve or orifice tube is an underperforming AC system.
  • Frost on AC evaporator or coming from the vents.
  • AC compressor constantly running.
