The Completion Walkthrough Checklist

Why this matters

A fix the customer never watched work is a callback waiting to happen. The last few minutes standing beside them, showing the repair run, handing off how to use it, and naming what to watch, is what turns finished work into a good review and heads off the "it is doing it again" call the first time the equipment sits idle between cycles. This card is the customer-present handoff, item by item. It is the human half, not the whole close: for the full tech-side close sequence (record, invoice, cleanup) see the job closeout checklist, and for the exact words to say see the completion walkthrough comms script.

Phase 1: Set the walkthrough up

Do not start it while you are writing the invoice; the customer reads paperwork as goodbye and stops listening.

• Finish the physical work and confirm it operates before you invite them over, so there is nothing to walk back.
• Get their attention and a couple of minutes: "Do you have two minutes, I want to show you what I did."
• Walk to the actual equipment together rather than describing it from the doorway.

Phase 2: Prove the fix, do not just claim it

Showing beats telling. A customer who watches it run believes it is fixed; one who only hears "all set" calls back at the first odd noise.

• Run the system through a full normal cycle under real conditions while they watch and feel the result.
• Have the customer operate it themselves once before you leave: the thermostat, the switch, the remote, the valve.
• Show the failed part and let them draw the conclusion, rather than telling them their old one was "really bad."
• Point at each thing you did at the work area; physically pointing slows them down enough to take it in.

Phase 3: Hand off how to live with it

Most callbacks are operation questions, not failures. Answer them now, on site, once.

• Show them the everyday controls and the correct normal settings.
• Point out where the shutoffs, the filter, the reset, or the breaker are, so they are not helpless at the next hiccup.
• State any maintenance the equipment needs and how often, in plain terms.
• Hand over the manuals or documentation that came with anything new.

Phase 4: Set expectations for the first day

Pre-explaining the small weird things stops the panic call; naming the real triggers gets you the call that matters.

• Tell them what is normal in the first day (a break-in smell, a cycle that feels different, air clearing a line).
• Name the specific signs that do warrant a callback (an active leak, no temperature change after a set runtime, a repeated trip).
• Make clear you are the one to call, with the number and the hours.

Phase 5: Get explicit acceptance before you pack up

Silence now beats a confused call tonight. Ask the direct question while you can still fix a concern for free.

• Ask plainly: "Does that all make sense, anything else while I am here?"
• Walk the immediate area with them and let them point at anything that bothers them.
• Get the sign-off your shop uses that the work is accepted and was demonstrated.

What not to do

• Do not skip the demonstration because you are running late; it is the single step that prevents the callback.
• Do not start the walkthrough with the invoice already in your hand.
• Do not assume they remember what was wrong; restate the original complaint and tie the fix to it.
