A service inspection is only as good as the system you use. Go through the system in the same order each time so you do not skip anything because you were interrupted.
§Before you start
- 01Find out what refrigerant the system contains
- 02Bring out the system's history and previous service reports
- 03Make sure that you have the right tools, parts and protective equipment
- 04Arrange with the customer what the inspection includes
§The actual inspection
- 01Read off the pressure on the high- and low-pressure sides and note them down
- 02Measure temperatures in and out and compare with expected
- 03Check for tightness and visible signs of leak
- 04Clean the condenser and evaporator for dust and dirt
- 05Check oil, filters and drain
- 06Check sensors, control, and settings
- 07Listen and look for unusual noise, vibration or wear
§Conclusion
- 01Correct small mistakes immediately if you have parts on hand
- 02Note what needs to be followed up on
