Documentation, Customer Communication, and Professional Practice

This domain tests the paperwork and conduct that protect the customer, the employer, and you. Questions often ask what belongs on a work order or how to handle a disagreement.

Documentation

  • A work order should record the complaint in the customer's words, your findings, tests and readings, parts used, labour, safety observations, and recommendations.
  • Include model and serial numbers, refrigerant type and amount recovered/charged, and the date.
  • Estimates require clear scope and authorization before work; record the approval.
  • Warranty claims need proof of purchase, installation date, and serial number.
  • Keep refrigerant and disposal records as required by federal and provincial rules.
  • Protect personal information under PIPEDA and provincial privacy laws; do not leave customer data visible.

Communication

  • Explain the fault in plain language, with options and costs. Avoid fear-based selling.
  • Distinguish what you know, what you suspect, and what needs further testing.
  • Do not diagnose definitively over the phone; book a service call.
  • Confirm the customer understands safety instructions, shutoffs, and maintenance.
  • Handle complaints by listening, acknowledging, and offering a specific next step.

Professional practice

  • Work only within your certification and licensing; refer gas, electrical, or refrigeration work outside your scope.
  • Do not disparage competitors or previous technicians.
  • Follow the manufacturer's instructions and the adopted code; document any deviation.
  • Keep callbacks low by verifying the repair and cleaning up.

Worked example

You replace a dryer heating element. On the work order you write the complaint ("no heat"), the readings (240 V at terminal block, element open at 30 Ω), the cause (failed element with lint-restricted vent), the repair (element replaced, vent cleaned), the verification (current 18 A, outlet temperature 65 °C), and the recommendation (clean the vent annually). You show the customer the lint and explain the fire risk without exaggerating.

Traps

  • Writing "repaired" with no readings.
  • Performing work beyond the authorized estimate.
  • Promising a warranty outcome you do not control.
  • Leaving customer information or keys unsecured.
