Before you drive out.

Reach for this once a call is booked and before anyone leaves for the site.

Without it, a tech can arrive with the wrong gear, no records, and no plan for trouble.

Step by step

7
  1. Write down the complaint word for word

    Keep the customer's own words. Add who said it and when. Save any theory for later.

    Write down · Note
  2. Ask the safety question

    Ask about gas, carbon monoxide, water near electrical, smoke, and movement. Any yes goes to emergency steps before the visit.

  3. Pull earlier records for this address

    Look for past visits, repairs, and readings. Treat them as leads to check on site, not as current fact.

    Write down · Note
  4. Get the unit's label

    Ask for a photo of the make, model, and serial label. Find the maker's instruction for that exact model and revision.

  5. Ask about age and past changes

    Ask when it was built and what was added. A date can raise suspicion and pick a test. It identifies nothing.

    Write down · Note
  6. Check instruments, access, and weather

    Confirm instrument range and calibration date. Bring ladder or roof gear rated for the job, and check the weather.

    Write down · Note
  7. Set the emergency plan

    Know the nearest hospital, the outside meeting point, the local emergency number, and who makes the call.

Done when

A finished run leaves the complaint in the customer's words, the safety answers, the records found, and the gear checks.

General guidance for a qualified person, not a finding about any home. The person on site decides.
