A day as a Field Service Technician
Your office is a van, and your boss is whatever broke overnight. You drive to customer sites, find out why a machine stopped, fix it, and leave the customer confident it won't happen again. The day below follows a tech who services commercial kitchen and refrigeration equipment across a regional territory.
From first dispatch to the last work order
Tablet check in the driveway
You open the dispatch app (ServiceTitan, FieldEdge or something your company built) before you've finished your coffee. Overnight, a restaurant logged a walk-in cooler running warm, and it's been bumped to the top of your list. You scan the other calls, check which parts are already on the van, and text the parts desk about a compressor contactor you used up yesterday.
The warm walk-in
The kitchen manager meets you at the back door, stressed, because there's product in that cooler. You read the pressures on your gauges, check the evaporator fan, and find a failed defrost timer that's let the coil ice over. You swap it from van stock, clear the ice, and watch the temperature start falling before you leave. You write it up with photos, because the next tech who comes here will read your notes.
Scheduled maintenance at a school kitchen
This is the quiet part of the job. You work through a preventive maintenance checklist on a dish machine and a couple of reach-in coolers: clean the condenser coils, check door gaskets, test safety switches, log readings. Nobody's watching and nothing's on fire. It's also the work that keeps the emergency calls down, so you don't rush it.
The call that eats the afternoon
A combi oven at a hotel throws an error code you've seen once in your life. You pull the service manual on your phone, test the sensor, and it reads fine. Then you call the manufacturer's tech support line and sit on hold. The fix turns out to be a control board that no distributor nearby has in stock, so you quote it, order it, and tell the chef it'll be a few days. The two calls after this one get pushed to tomorrow, and dispatch isn't thrilled.
Paperwork in the parking lot
You close out work orders on the tablet, note parts used, get the chef's signature, and flag the hotel job for a return visit. You restock from the shop or a supply house on the way home. Some nights you're on call, which means your phone could ring at dinner about a freezer alarm.
What separates a good tech from a parts changer
Anyone can swap parts until a machine starts working. The techs dispatchers fight over are the ones who diagnose before they replace, so they don't burn through van stock and return visits. They also write notes another tech can use and talk to customers like adults. You'll hear managers call this first-time fix: did the job get finished on the first visit. It's the thing you get judged on more than anything else, and it's why good troubleshooting habits matter more than speed early on. The other half of the job is people. You're often the only face of your company the customer ever meets, and a calm explanation at a stressful moment can save an account.
How techs end up in the van
Trade school or a community college program
An HVAC-R, electronics or industrial maintenance certificate is the most common way in. You'll learn electrical basics, reading schematics and meter work, which is exactly what interviewers poke at. If you'll handle refrigerant, you'll need EPA refrigerant handling certification in the US, and most programs prepare you for it.
Moving up from a shop or warehouse role
Plenty of techs started as a bench tech, parts runner, installer or helper. You learn the equipment on the inside, ride along with a senior tech, and get your own territory once you can close calls without help. It's slower but you get paid while you learn.
Military maintenance experience
Veterans who worked on aircraft, vehicles, generators or electronics often walk straight into field roles. Companies like the discipline and the habit of following procedure, and many manufacturers run their own factory training once you're hired.

Questions people ask
Do I need a license to be a field service technician?
It depends on the equipment and where you work. Refrigerant work in the US needs EPA refrigerant handling certification, and some electrical, gas or HVAC work needs a state or local license. Rules differ by state and city, so check your licensing board and read the posting closely. Many medical, office and industrial equipment roles don't require a license at all, just manufacturer training.
Will I get a company vehicle?
Usually, yes. Most employers give you a stocked van or truck, a fuel card and a tablet or phone. Ask in the interview whether you can take the vehicle home, since that decides whether your day starts in your driveway or at the shop. A clean driving record is often a condition of the job.
What's the hardest part of the job?
Not knowing what your day holds. A simple call turns into an afternoon-long puzzle, a part is back-ordered, or an emergency pushes everything else back. You'll also carry the customer's frustration when their equipment is down and costing them money. People who last learn to set honest expectations early and not take the angry calls personally.
