A day with the field supervisor

Wake to bed.

12 waypoints. 2 peak-stress hours.

5:30a

Boots on

Coffee in the steel mug from the last company picnic. Pulls up the dispatch board on the phone at the kitchen table — eight techs out today, two ride-alongs on the calendar, and a callback flag from the new tech on truck seven.

6:30a

Drive to shop

Voice memo to the Service Manager about callback patterns trending in the Westside zip — third one this month, all on the same Installer crew. Pulls up truck seven's metrics on the phone at the red light.

7:00a

Shop check-in

Walks the bay before techs roll out. Coffee for the new tech, two minutes on the callback without making it a thing — asks him to walk through the diagnostic, listens, doesn't fix it for him. Documents the conversation in the coaching log on the phone before he forgets the words he used.

8:30a

Ride-along

Climbs into truck three for a planned ride-along with a tech six months in. Sits in the cab on the drive over reviewing his last twenty tickets — close rate is fine, average ticket is light.

9:00a

Customer kitchen

Stays at the back of the kitchen while the tech walks options. Resists the urge to step in when the customer pushes back on the mid-tier — the tech holds the price, lets the silence sit, closes it. Nods once on the way out.

11:00a

Phone coach

Apprentice on truck four calls about a stubborn ECM blower. Walks him through the test sequence on the phone instead of driving over — pulls voltage, then control signal, then resistance. Logs the call in coaching notes from the truck cab.

12:30p

Lunch at the shop

Sandwich at the parts counter with the warehouse manager. Two minutes about the R-410A pull rate, then the high school playoff game his kid pitched in last weekend. Walks back to the truck before the conversation drifts.

1:30p

QA spot check

Drops in unannounced on a completed install from yesterday — the same crew tied to the morning callback flag. Pressure-tests the linesets, checks the condensate trap pitch, snaps photos of the disconnect wiring. Two issues, neither dangerous, both teachable.

3:00p

Escalation

Dispatch reroutes him to a customer who refused to pay on a heat pump diagnosis. Sits at the kitchen table, walks the readings on the tablet, agrees the tech rushed the explanation but holds the diagnostic charge. Customer signs.

4:30p

Crew debrief

Pulls the install crew into the bay before they wash trucks. Walks the two QA findings on the whiteboard, names them, shows the photos, gets the lead to walk the fix. Five minutes, no drama, written up in the coaching log before he leaves the shop.

5:30p

Service Manager handoff

Stops by the Service Manager's office on the way out. Walks the Westside callback pattern, the ride-along notes, the install-crew QA findings. Flags the new tech's diagnostic gap — wants to put him on a structured ride-along next week.

8:00p

Last look

Couch, phone, tomorrow's board. Confirms the structured ride-along is on the calendar, replies to the apprentice's late text about the ECM blower — turned out to be the control board, exactly what they walked through. Plugs the phone in.
