Calling someone new to work on your home can feel like a bit of a gamble. We want you to feel good about who you called.

For Ernest and Donald, that means taking care of the first job and earning your trust for the next one. When you need help again, we hope you’ll already know who to call.

Here’s what they’d tell someone calling Ongaro & Sons for the first time.

Team approved. 💚 One of the North Bay's Best Places to Work, decided by the people who work here.

The North Bay Business Journal's 2026 list is out and Ongaro & Sons is on it. The rankings come from employee surveys, so this one belongs to the team: the techs, the installers, the dispatchers, the office crew.

Family-owned since 1932. Still a place people want to come to work. Thank you, team.

Summer's not over in the North Bay, September can still bring real heat, and fire season is just getting started. Don't let your guard down. If your AC limped through August, get it sorted now, and it's the perfect moment to think about backup power before the fall outages. We'll help you get ahead of all of it.

Most folks never think about their electrical panel until the day they go to add something big (a range, an EV charger, a heat pump) and find out there's no room left for it. That's when a panel upgrade goes from "someday" to "can't move forward without it." If your panel looks like it came with the house and you've wondered what it can actually handle, it's worth a look before you buy the new gear, not after. Give us a shout and we'll tell you what you've got to work with.

The guys who clown around on a sunny driveway are the same ones you want in your house for a full day. People who actually like the work and like each other tend to be careful with your floors, tidy up after themselves, and explain what they're doing instead of grunting at you. That's the part you can't see on a quote, so here's a look at it.

Run the same business long enough and you'd think the spark would fade. For Ernest and Donald, it hasn't. The way they tell it, it's hard to get bored; the work keeps moving and changing, so there's always something new to take on. But the part that really keeps them coming in is the people they work with. That's what makes it feel like a family business. Ep.8 of the series.

That entire pipe was packed solid with tree roots. 🌳 They sneak into the smallest crack in a sewer line, grow toward the water, and don't stop until the house backs up. This one was too far gone to clear, so we dug it out and replaced the bad section.

We asked the family about the nicest thing a customer ever said. 💚 Ernest remembered an Ongaro coming out to fix their heat on a holiday, generations back, and he got emotional just telling it. Ep.7.
