# A technician returns to equipment the company has serviced

A technician is due at a building with several pieces of equipment. The owner wants the history of the right unit in one place before the visit.
In this fictional example, the equipment reference and two work records are available. The assistant is asked to prepare a handoff, leaving the technical assessment to the technician.

## Fictional example

The owner's request: Prepare the service history of F-12 for the technician and flag anything still unclear.

Information provided:
- New visit and equipment record both identify furnace F-12 at the service location.
- Work card, 10 March: filter replaced; part F16.
- Service note, 2 October: thermostat concern reported; no resolution stated in the supplied note.

Example result: F-12 history: 10 March, filter replaced with F16 (work card). 2 October, thermostat concern reported; outcome not stated (service note). Before the visit, confirm the unit and check for any later record about the thermostat.

The next step: The owner checks the unit reference and passes the history to the technician, who decides what to inspect.

## Start with the equipment reference

The new job names furnace F-12 at the service location. The equipment record also identifies F-12 as the furnace at that location, so the owner can match the visit to the two supplied service notes.

If the label or location did not match, the handoff would need a check before anyone treated the old work as the history of this unit.


## Keep the history in order

A 10 March work card records a filter replacement using part F16. A 2 October note records that a thermostat concern was reported, but the supplied note does not say how it was resolved.

The prepared handoff can name both records and their dates. It should not turn the open thermostat note into a diagnosis or assume that the filter is needed again.


## Give the technician a starting point

The owner checks that F-12 is the intended unit and gives the technician the concise history and source references. The technician can then verify the equipment and decide what to inspect.

If another work card later resolves the thermostat concern, it can be added to the history with its date. The absence of that card from this package does not establish what happened in the field.


## Questions you may have

### Does the previous filter part tell the technician what to bring now?

It is a record of what was used previously. The technician decides what the current visit requires.

### Does an unresolved note mean the thermostat is faulty?

No. The supplied note records a concern without an outcome; the technician assesses the current issue.

### What if the equipment label does not match F-12?

Check the equipment and location records before using this history for the visit.
