The Day Our Backup Power Plan Failed
It was a Tuesday morning in late February 2024. I was in the middle of a routine quality audit when the phone rang. “Our standby generator at the Westside facility just died. Completely seized. We need a replacement in two weeks.”
As quality manager, I review every major equipment purchase before it hits the floor – roughly 200 items a year. But I’d never had to spec a generator under a deadline like this. Normally I’d run a full competitive bid, get three quotes, check references. Here’s the thing: I had two weeks to decide, and procurement had already burned a week trying to find a rush replacement.
So I did what any pragmatic buyer would do: I narrowed the field to two brands – Briggs & Stratton and Generac. Both had good reputations. Both offered 20 kW standby units that fit our load requirements. But the real decision came down to pricing – or so I thought.
The Quote That Looked Like a Steal
The first quote landed from a local distributor for a Briggs & Stratton generator. The line item was $14,200 – base unit, no installation. I thought, “Great, under budget.” Then the second quote for a Generac came in at $16,800, same spec. Obvious choice, right?
But I paused. My gut told me something was off. I’ve learned the hard way that the lowest price is rarely the final price. So I started digging into what wasn’t included.
The Surprise Wasn’t the Base Price – It Was Everything Else
I called the Briggs distributor and asked point-blank: “What else do I need?” The sales rep rattled off a list:
- A propane conversion kit if we wanted to run on LP instead of natural gas – $1,900
- An inverter battery charger to keep the startup battery topped off – $420
- A VFD (variable frequency drive) for the facility’s critical HVAC pump – $2,800 (they said it wasn’t included because “most people don’t need it”)
That’s over $5,000 in add-ons – 36% above the sticker price. The Generac quote, on the other hand, listed everything upfront: “Includes propane conversion kit, inverter charger, and VFD compatible with common pump motors.” The total: $17,200. Only $400 more than the Briggs “all-in” price, but with no surprises.
I was frustrated – not just at the Briggs distributor, but at myself for nearly falling for the lowest headline number. The most frustrating part? You’d think a written quote would mean everything is listed. But interpretation varies wildly. The surprise wasn’t the price difference. It was how much hidden value came with the “expensive” option – support, clear specs, no nickel-and-diming.
The Propane Conversion Kit Question
Let me dig into that propane conversion kit, because it’s a classic example. The generator propane conversion kit for Briggs & Stratton is a common add-on for facilities that already use LP tanks. But most people don’t realize it’s not a one-size-fits-all part. The kit includes a regulator, a new fuel hose, and sometimes a different carburetor gasket. If you install it wrong, the engine runs lean and damages the valves.
We actually had a case in 2023 where a contractor installed a generic conversion kit on a Briggs generator without verifying the orifice size. The result? A $22,000 engine rebuild and delayed our launch by three weeks. That’s the kind of hidden cost that never shows up on the first invoice.
Per FTC guidelines (ftc.gov), advertising claims about “compatible with all fuel types” must be substantiated. So when a vendor says their conversion kit works “for most Briggs generators,” ask for the specific model list. It’s not being difficult – it’s being transparent.
Inverter Battery Chargers and VFDs – The Unseen Essentials
Another line item that surprised me was the inverter battery charger. A standby generator needs a healthy battery to start when the grid goes down. A cheap trickle charger might work, but an inverter charger conditions the battery and prevents overcharging. The $420 part was non-negotiable for us – but the Briggs distributor listed it as an option, while the Generac quote included it.
Then there’s the ac tech VFD – variable frequency drive. Our facility runs a 15 hp cooling pump that can’t handle the sudden surge when a generator kicks in. A VFD soft‑starts the pump, saving wear and tear. The Briggs distributor said “we don’t usually include that unless requested.” The Generac rep said “we assume you’ll need it for a facility this size, so it’s included. If you don’t, we’ll credit it back.” That’s transparent pricing.
I ended up choosing the Generac unit, even though the headline price was higher. The total cost of ownership was actually lower. But the lesson stuck with me: transparent pricing builds trust. The vendor who lists all fees upfront – even if the total looks higher – usually costs less in the end.
A Tangent That’s Actually Relevant: Air Filter Maintenance
You might wonder why I’m mentioning air filters in a generator story. Here’s why: a few weeks ago, one of our technicians asked me how to clean lawn mower air filter (they also maintain the landscaping equipment). I showed him the standard procedure – remove, tap out dust, wash with soap if foam element, dry, re-oil if needed. Then he said, “The generator manual says the same thing.”
Which got me thinking: how many people neglect their generator’s air filter because they assume it’s complicated? It’s not. And yet, a dirty air filter can cause the engine to run rich, waste fuel, and reduce lifespan. The generator supplier never mentioned that. Had I known the maintenance requirements upfront, I might have factored in ongoing costs differently.
Bottom line: when evaluating generators, ask about all consumables – air filters, oil filters, spark plugs. Their replacement intervals and costs should be transparent too.
What I Learned: Transparency Is Cheaper in the Long Run
Looking back, that two-week deadline forced me into a decision I normally wouldn’t make. But it also exposed how much hidden friction exists in commercial generator buying. Here’s what I now do for every equipment purchase – and what you should consider too:
- Ask for a “full scope quote” that includes every accessory, installation, and testing fee. If the vendor resists, red flag.
- Compare total cost, not base price. The difference between Briggs and Generac often isn’t quality – it’s how they package add-ons.
- Verify claims with hard data. According to the FTC Business Guidance on Advertising (ftc.gov), any claim about “storm readiness” or “dual fuel capability” should be backed up by test results. If the supplier can’t show you their testing protocol, ask why.
- Always check the fine print on propane conversion kits – warranty may void if installed by a non-certified technician.
- Budget for maintenance. A clean air filter (and knowing how to clean it properly) can extend generator life by years.
I’ve been doing this job for years, and I still get surprised. The surprise wasn’t that the cheap quote had hidden costs. The surprise was how much easier it is when a vendor just tells you the real price from the start.
So if you’re comparing Briggs & Stratton vs Generac generators right now, don’t just look at the sticker. Look at what’s not written down. That’s where the real cost lives.
