Customer Comms Script - Job Completion Walkthrough

Why this matters

The last five minutes of a job determine the review, the referral, and the callback rate. A walkthrough that names what was done, shows the customer what was replaced, demonstrates the new equipment works, and explains what to watch for converts technical work into perceived value. Customers do not assess plumbing solder joints; they assess whether the tech treated them like an adult who deserved an explanation. This reference gives you the script, the demonstration steps, and the close-out items that turn a finished job into a satisfied customer and a documented record. The same script protects the company when the customer calls a week later claiming the tech "did not say anything was wrong with the X" - because the walkthrough was performed, documented, and signed.

Walkthrough structure

A complete walkthrough has six parts and runs three to seven minutes for most service work, longer for installations.

1. Recap what you came for.
2. Walk to the work area and point at what was done.
3. Demonstrate the system or component working.
4. Hand over removed parts (when applicable).
5. Explain what to watch for and when to call back.
6. Close out paperwork, payment, and the warranty record.

Skipping the demonstration is the most common omission and the most expensive. A customer who watches you turn on the furnace and feel warm air at the register believes the furnace is fixed. A customer who hears "all set, the furnace is fixed" but never sees it run will call back the first time the thermostat is between cycles.

The recap

Start the walkthrough at the customer, not the equipment. Confirm what they thought you were here for, and tie it to what you found.

Hi [Customer first name], do you have two minutes? I want to walk you through what I did today. You called us out because [original complaint - water under the sink, no cooling upstairs, breaker tripping]. What I found was [diagnosis - failed supply line gasket, low refrigerant from a slow coil leak, a 20-amp breaker on a circuit drawing 24 amps]. Here is what I did about it.

The recap closes the loop on the original problem. Customers do not always remember exactly what they reported on the phone; restating it shows you listened and gives them a chance to add anything they forgot.

The point-and-show

Walk to the work area. Physically point at each item.

Here is the new gasket - I will leave the old one with you so you can see it failed. I also tightened the supply nut to spec, and you can see I cleaned up the cabinet floor. I ran the faucet for three minutes with the cabinet open, and as you can see, the floor is dry.

Physical pointing matters because it slows the customer down enough to take in what you are saying. People absorb a fraction of what they hear; they absorb more of what they see while hearing.

The demonstration

This is the step that drops callback rates. Do not skip it even if the system was running fine on arrival.

• Heating system: cycle the thermostat to call for heat. Stand at a register with the customer and feel air movement and temperature.
• Cooling system: cycle to call for cool. Same drill.
• Electrical: at the panel, show the breaker holding under load. At the receptacle or fixture, plug in the load tester or turn on the device.
• Plumbing fixture: run water for a defined time. Show the customer the absence of drips at every joint you worked on.
• Appliance: run a representative cycle. Wash with a small load, dry with a damp towel, dishwasher with a few dishes.
• Garage door, gate, pool pump, irrigation: run a complete cycle from start to finish.

Have the customer operate it once themselves before you leave. Hand them the thermostat, the switch, the remote. The first independent operation should happen while you are still on site.

The hand-over of removed parts

Bring removed parts to the customer unless they have asked you not to. Show them, then ask whether they want to keep them or dispose of them.

This is the old capacitor I replaced. You can see the top is bulged out - that is the failure. Want me to take it, or do you want to hang on to it?

It makes the work tangible and provides physical evidence the part was actually replaced if a dispute arises later. Note disposition on the work order.

The watch-for-and-call-back

This is where you head off the next service call. Tell the customer what is normal and what is not, in plain language.

Over the next 24 hours you might notice [expected smell from new motor windings burning off / brief water hammer as air clears the line / one or two thermostat cycles that feel different]. That is normal. Call us back if you see [active leak, no temperature change at the registers after 20 minutes of runtime, a breaker trip].

This script does three things. It pre-explains the small weird things that always happen after fresh work so the customer does not panic. It defines the conditions that warrant a callback so they do not call about a non-issue and so they do call about a real one. And it positions the company as the place to call rather than a competitor.

Paperwork and payment close-out

The walkthrough ends with the documentation, not before it.

• Confirm scope and price. Walk through the invoice line by line.
• Capture the signature. The signature attests the work was completed and the walkthrough was performed.
• Photo the completed work. Before-and-after photos belong in the job record.
• Confirm warranty terms - manufacturer period, labor period, and conditions that void either.
• Hand over manuals or documentation that came with new equipment.
• Schedule the next visit if a maintenance plan applies.
• Ask if there are any other questions before leaving.

What not to do

• Do not start the walkthrough while writing the invoice. The customer reads invoice-writing as wrap-up; their attention is gone.
• Do not assume the customer knows what was wrong. They were told something on the phone and may have forgotten the details.
• Do not say "your old was really bad." It reads as upselling. Show them the part and let them draw the conclusion.
• Do not leave the walkthrough optional. Every job, every time.
