Field Service Checklists: Getting the Work Done Right Every Time

A good checklist breaks "service the unit" into the steps that make up a service. How to write one technicians will follow, and how to make the critical steps impossible to skip.

A checklist is the cheapest quality control a field service business has. It breaks "service the unit" into the six steps that actually make up a service, so every technician does them every time and the record shows it.

When checklists fail, it is rarely because people refuse to use them. Usually they are too long or too vague, or they have become tick-boxes nobody reads.

What a checklist is for

  • Consistency: the customer gets the same service whoever arrives.
  • Quality: the steps that matter most are never skipped.
  • Training: a new technician learns the job by doing it.
  • Evidence: a record of what was done, by whom and when.

How to write one

Keep it short, with six to ten items for a routine visit. If it needs thirty, split it into sections or into different kinds of job.

Write every item as an action. "Clean the condenser coil" rather than "condenser coil", and "Photograph the serial plate" rather than "check serial".

Make each item specific enough to fail. "Check the unit" can always be ticked, but nobody can honestly tick "Measure and note the amp draw" without doing it.

Put the items in the order they are done on site.

Mark the critical ones as required. A few steps must never be skipped, such as isolating power, a safety test or the final test run. If they are required, the job cannot be completed without them.

Ask for photos where proof matters: before and after, the serial plate, the finished installation.

Examples

A split AC service:

  1. Isolate power
  2. Clean or replace filters
  3. Clean the evaporator coil
  4. Clean the condenser coil
  5. Flush the condensate drain
  6. Note the gas pressures
  7. Test run and note supply air temperature
  8. Photograph the unit after service

An office cleaning visit:

  1. Empty all bins
  2. Clean and restock washrooms
  3. Clean kitchen surfaces and appliances
  4. Vacuum carpeted areas
  5. Mop hard floors
  6. Photograph the washrooms when finished

A site inspection:

  1. Photograph the site on arrival
  2. Check fire exits are clear
  3. Check extinguishers are present and in date
  4. Note any damage or hazards
  5. Photograph anything that needs action

Keeping checklists alive

  • Review them every few months. Items everybody skips are either useless or unclear.
  • Ask the technicians, who know which steps are missing and which are pointless.
  • Look at repeat visits. A fault that keeps coming back often points to a step missing from the checklist.

In Movtro

In Movtro each job type can have its own checklist, and every new job of that type starts with it. Any job can also have extra items of its own. Technicians answer on their phone, with or without signal, and Movtro records who completed each item and when. Required items must be answered before the job can be completed. Photos, notes, parts and the customer's signature are added to the job alongside the checklist. For repeat work, set the checklist once on a recurring job and every visit starts with it. When one visit covers several assets, the checklist repeats for each.

Movtro job checklist on a phone with every item answered, including area treated, product, quantity and a required safety step.

An item can be a tick, yes/no/N-A, a reading with a unit and an allowed range, short text, a pick-list or a photo of the step. Readings outside their range are flagged and Movtro reports a problem on the job by itself, so the office hears about it without the technician having to raise it. A follow-up question can be set to appear only on a given answer, and a group of questions can be repeated as many times as needed on one job. Questions can carry points, with a pass mark set on the job type, and the job, the customer portal and the service report show the score. Every answer also goes into the customer's service report PDF and into the Checklist answers report (Reports → Checklist answers, CSV or PDF).
