Field service answers 24/7, every day of the year, for industrial and commercial generators across Alberta — ours and other makes. Technicians go out from Red Deer to find the fault and fix it, and a rental set can carry the site if the repair will take longer than the load can wait.
A technician who knows the make, the symptom and the alarm before leaving Red Deer brings the parts and the manual for that set, instead of driving out to find out what is needed and driving back for it.
Whether the load is down right now, back on the utility, or carried by something else. It decides what goes out first.
Make, model and serial from the nameplate, the kW rating, and the fuel it burns.
Will not crank, cranks but will not fire, starts and shuts down, runs but the power is wrong, or will not take the load.
The alarm or fault code on the screen. A photo of it is better than a description.
The hour reading, when it was last serviced, and anything that was done to it recently.
Where it is, how to get in, who meets the truck, and the orientation or PPE the site requires.
Most generator failures announce themselves in one of a handful of ways, and each points at a short list of suspects. The table is where a technician starts, not where the diagnosis ends — a meter on the set and the controller's history settle it.
Resetting an alarm and trying again is tempting. If the set shut itself down on oil pressure or temperature, running it again can turn a small repair into a large one. Note the alarm, leave it shut down, and call.
| Symptom | First suspects |
|---|---|
| Will not crank | Batteries and charger, cables and terminals, the starter, or a controller left out of auto or held by a latched emergency stop. |
| Cranks but will not start | Fuel: an empty or water-logged tank, gelled diesel in the cold, plugged filters, air in the lines, a closed valve or low gas pressure. On gas engines, the ignition. |
| Starts, then shuts down | A protective shutdown doing its job — low oil pressure, high coolant temperature, low coolant, overspeed — or a failed sender telling it so. |
| Runs, but voltage or frequency is off | The governor or the voltage regulator, a load the set cannot hold, or the engine short of fuel or air under load. |
| Will not take the load | Overload, a large motor starting across the line, a tripped breaker, or the transfer switch not signalling or not moving. |
| Runs hot | Low coolant, a slipping belt, a plugged radiator, a failed fan, or an enclosure that cannot breathe. |
| Smoke, leaks or noise | Black, oily exhaust after long light running points to wet stacking; white smoke or coolant loss to the cooling system; knocking to something mechanical. Shut it down and call. |
Some faults are a part and an afternoon. Others wait on an engine component that has to be found, or a rebuild that takes the set off its pad. If what the generator protects cannot be without backup that long, the repair and the cover are best planned together.
NexSource is a rental fleet as well as a service shop. A rental set connected through a transfer switch can carry the critical load while the permanent unit is worked on, and comes out again once it is back in service.
Getting that right means matching the rental to the load and the connection point: voltage, the amps the switch and cable must carry, and whether the site needs an automatic transfer because nobody is there at night.
Emergency power distribution covers the panels, switches and cable side; commercial generator rentals and generator rentals across Alberta cover the sets themselves.
NexSource rents, sells, buys and rebuilds generators, so there is no reason to steer a failing unit toward one outcome. The choice comes down to a few plain questions.
The fault is contained — a sender, a regulator, a starter, a charger — and the engine and alternator are otherwise sound. Fix it, test it under load, and put it back to work.
The engine is worn rather than broken, the oil results have been trending the wrong way, or a major failure has hit a set that is otherwise worth keeping. An overhaul resets the engine without replacing the whole package.
Parts are hard to find, repairs keep coming, or the load has outgrown the set. Then the money is better spent on a used or surplus generator or a new NPI Series package sized to today's load.
Whichever it is, ask for the comparison on paper. If the load has changed since the set went in, the generator sizing guide and the power calculators help check what the replacement should be.
Plenty of call-outs trace back to something a routine visit would have caught: a weak battery, a filter left too long, a block heater that quit in the fall. Once the set is running again, it is worth asking whether it is on a schedule. The generator service page covers planned maintenance, oil sampling and load bank testing.
Planned maintenanceField service answers 24/7, every day of the year, and technicians are dispatched from our Red Deer yard. How soon one reaches you depends on where the site is and what is already under way, and the dispatcher will tell you honestly when you call.
Yes. Our technicians work on other makes as well as our own, and carry parts for the fleet we support most often. Give the make, model and serial when you call so the right parts and information go with the technician.
Fault-finding and most repairs are done where the generator sits. An overhaul or rebuild can make more sense in the shop in Red Deer, and the quote will say so before anything is moved.
Often, but not always. Hours, the condition of the engine and alternator, how easily parts can be had, and whether the set is still the right size for the load all decide it. Where a rebuild or a replacement is the better answer, you get that comparison in writing.
Yes. A rental set from the NexSource fleet can carry the load, connected through a transfer switch with the distribution to suit, until the permanent unit is back in service. It is quoted alongside the repair.
There is no flat rate. It depends on what is found, the parts, the distance from Red Deer and whether the work is done on site or in the shop. Fault-finding comes first, and the repair is quoted in writing once the cause is known.
Field service answers 24/7, every day of the year. Have the nameplate, the alarm and the site location to hand. NexSource works from Red Deer and repairs generators on sites across Alberta.
