Commercial Generator Spring Reset: What We See Every Year After Winter

Every spring in the Lower Mainland, we start getting the same calls. Not emergencies. Not yet. More like, “Hey, can you come take a look at this? Just want to make sure everything’s good.” And almost every time, it’s the same situation.

“It should be fine… but we’re not totally sure”

We were at a building in Burnaby a couple weeks ago. Nothing unusual. Mid-size strata, standard backup setup. The manager told us it had run earlier in the year and should be fine. That’s usually how it starts.

We went through the system and pretty quickly a few things showed up. The battery turned the unit over, but not confidently. The testing through winter was a bit inconsistent. The generator hadn’t really been run properly under load in a while. Nothing had failed, but nothing had really been verified either.

This is pretty typical for this time of year

Winter here isn’t extreme, but it’s enough to put some strain on things. Cold starts, moisture, and long periods where systems just sit. And realistically, maintenance doesn’t always stay perfectly on schedule. Things get busy. Tests get delayed. It happens.

By the time spring hits, a lot of buildings are in the same spot. Everything looks fine on the surface, but no one has full confidence in it.

The problem with backup systems

Generators don’t really give you a warning. They don’t slowly degrade in a way you notice day to day. They either start and run properly, or they don’t. And when they don’t, it’s usually at the exact moment you need them.

We’ve seen batteries that finally give out during an outage. Units that trip as soon as load comes on. Small issues that sat quietly all winter suddenly become the reason the system doesn’t carry. None of those felt urgent beforehand.

Why spring matters

This is the window where you can still deal with things properly. There’s time to go through the system, run it the way it’s supposed to be run, and catch anything that’s even slightly off. Most of the time, it’s not a big fix, but it’s enough to make the difference later.

What we usually say this time of year

If your generator hasn’t had a proper look since before winter, it’s worth going through it now. Not because something is obviously wrong, but because this is when we tend to find the things that would turn into a problem later. Every spring, it’s the same pattern. Nothing seems urgent. Everything should be fine. And then we take a look, and there’s just enough there to fix. Better now than when the power goes out.
