Generator servicesForty-five years of licensed electrical work across Eastern Ontario. Panel upgrades and rewiring, commercial fit-outs and service, industrial power distribution and controls. One firm, one standard.
Three ways to get the system right.
We meet customers where they are. Most want the entire project handled end-to-end. Some have already bought a generator and need it installed properly. Some are still shopping and want sizing advice before they buy.
Every project starts with our intake form. If you can, add a short video or a few photos of your property. It tells us most of what we need, so the next step is a real conversation about your home. Every generator system we touch is sized to the home, the load, the fuel source, and the property.
We design it, supply it, install it, commission it.
The traditional path, and the one most of our customers choose. If you can, send a short video or a few photos of your property with the intake form; it helps us review your project faster. If you'd rather not, no problem: we'll go over the details with you by phone. Then we book your on-site assessment, then deliver a written proposal with one all-in price covering every piece of the project: generator, automatic transfer switch, mounting pad, electrical connection, gas connection, ESA permit, final inspection, warranty registration, and commissioning. One accountable provider from the first conversation to the day your system runs its first test cycle. If anything is wrong with the install, our name is on it and we fix it.
Already bought a generator, or about to?
If you've bought a standby generator from a big-box store or online, we can install it properly. If you're still shopping, we can help you size it correctly before you spend the money.
Two ways to work with us, depending on where you are in the process.
A short phone or video consultation before you buy. We walk through your home, your loads, your fuel source, and your usage. You leave the call with a sizing recommendation and the questions to ask the retailer before you put money down. The goal is simple: don't spend thousands on the wrong unit.
You already have the unit. We can install a standby generator you've purchased elsewhere, including from Costco or other big-box stores. Send photos with the intake form and we'll give you an installation price from your photos. We book a site visit once you've approved the price.
The photos we need: the unit's data plate or box label, your electrical panel, your hydro meter, your gas meter or propane tank, and where you'd like it installed.
One note on getting to us: if you've seen a Generac commercial and want our service, call us directly at 613-929-9679 or use the form on this site. Generac's 1-800 line routes leads through their own distribution system, which doesn't always send Kingston-area customers to Kingston-area dealers. Calling us directly is the surest way to reach the local contractor you're looking for.
When the original installer can't help.
Saturday morning, May 30, 2026. A large power outage hit the area north of Kingston. By mid-morning we'd taken two calls from generator owners who weren't our customers — different units, different installers, different problems.
The first generator we got running in about an hour. The second was a dead battery and a failed controller, likely caused by an ant infestation inside the unit. Both customers had a working generator by the end of the day.
Both calls had the same underlying problem: their original installers weren't equipped to service the units they'd sold. One install was three to four years old, the other had just passed five years — out of warranty. Both were honestly pretty good installations, technically. But after the install, the customer was on their own. That's the position homeowners end up in when the company that sold them the generator was never authorized to service it. It's the reason we tell people to check dealer status before they sign, not after.
Why this keeps happening:
Generac certifies dealers through ongoing training, technician certifications, and parts and service infrastructure. Most contractors who install generators don't maintain that authorization — they install, they collect, they move on. When something goes wrong years later, the manufacturer's 1-800 line routes the customer somewhere else.
Think of it the way you'd think about cars. Buy a Ford from a Ford dealership and you know they can service it five years later. Buy a Ford from a used lot and you might be fine, or you might be hunting for someone qualified to fix it.
What this means for you:
We service the generators we install, and offer optional annual and priority service plans to our installation customers. Factory-trained, with direct access to factory parts and technical support.
Note on emergencies: We don't routinely work weekends, but we do respond to genuine emergencies — especially during regional outages. The Saturday calls above happened during a widespread power event. For normal service or maintenance, schedule during business hours.
Customer Reviews
47+ customers across Eastern Ontario.
We recently had a power outage due to a wind storm on a Friday evening . HydroOne initially said the outage was approx 3 hours. Our Generac generator failed to start. Unfortunately HydroOne advised the outage was going to be 19 hrs in total. Once we found out the outage was going to be extended, I call Robb KNAPP and advised him of the situation. This was approx noon on the Saturday and he was at my rural property within the hour. He quickly diagnosed the issue (dead battery) replaced it and checked the unit for any other faults. If I could provide a 10 Star Rating ⭐ I would. Well done Robb. Thank you so much quick response. Bob Abrams

The back office of Knapp's Electric runs on software built in-house by the owner.
Generator Hub is our customer relationship management system. Quotes, invoices, service history, scheduled maintenance, photos from past installs, direct customer messaging, generator monitoring, fleet service tracking — all in one place. Customers log in at hub.knappselectric.ca to see their account 24 hours a day.
It exists because the off-the-shelf options for tradesmen weren't designed for how a real electrical contracting business actually runs. They're built for someone, but not for us. So we built our own.
Generator Hub is one of six platforms we've built: a quoting and estimating tool, a receipt and expense tracker, a panel schedule generator, a building-cost planner, a customer-facing AI companion app, and the CRM itself. Same business, same owner, same forty-five years of trade experience — applied to the back office as much as to the work in the field.
What this means for the customer: cleaner records, faster responses, service reminders that actually go out on time for customers on a service plan, and a customer relationship that holds up over years and decades. Not over the next install. Over the next twenty.

What you can expect from us.
Authorized dealer, not just an installation dealer.
Most dealers can sell and install. Only an authorized dealer is factory-trained, can open a warranty claim, and can carry out warranty repairs. The company that installs it is the company that services it.
ESA permits handled in-house.
No coordinating with a separate electrician — we are the electrician.

One firm, start to finish.
You deal with one company from quote to commissioning. The same firm that quotes the work manages it and stands behind it.
Maintenance the right way — based on your generator, not a calendar.
Generator maintenance isn't a once-a-year ritual. It's tied to how much your generator actually runs. Generac specifies maintenance intervals based on operating hours — and modern units track that automatically. Our service approach reflects that reality.
When you're a Knapp's customer, we schedule maintenance based on your actual run hours and our years of experience servicing units in Eastern Ontario conditions. We pay particular attention at years three through five, when batteries start needing replacement and components have accumulated real wear.
Service plans are optional. Customers on a plan get scheduled service reminders through Generator Hub. Without a plan, we won't chase you with reminder calls. When you need service, reach out and we'll send our rate card for approval before booking the work.
