Life at SumZero

Real Work. Real People. Real Purpose.

At SumZero, we don’t just build high-performance HVAC systems — we build careers with meaning.

When you step onto our team, you’re joining a crew that works hard, looks out for one another, and holds itself to a higher standard. This isn’t just a job. It’s a place where your growth matters, your ideas count, and the people beside you are serious about doing work they’re proud of.

Build Your Career With Us

We Show Up With Purpose

Whether it’s a toolbox talk at 6:30 a.m. or a clean install that wraps at 5:00 p.m., our day starts with intention and ends with execution.

We gather often — not just to share updates, but to celebrate wins, align around goals, and stay rooted in our values. That means:

Monthly team meetings
Summer BBQs and shared meals
Recognition ceremonies for teammates who go the extra mile
Corporate breakfasts, birthdays, and laughs in the breakroom

We work hard — but we don’t forget to look up, connect, and celebrate along the way.

We Grow People, Not Just Roles

Growth isn’t a buzzword here. It’s a commitment — built into the way we coach, review, and promote from within.

We offer:

Weekly check-ins with leaders who care about your goals
1:1 mentorship for both technical and personal development
Regular performance reviews that actually mean something
Training beyond tools — including leadership, communication, and mindset

Whether you want to lead a crew, design systems, or master your craft — you’ll never be left to figure it out alone.
‍

You grow. We grow. It’s that simple.‍

Recognition That Reflects the Work You Actually Do

We see the quiet wins — the tough calls, the early starts, the long drives, the one-percent-better days.

And we celebrate them.

Hero of the Month: for teammates who show integrity, grit, and care
Crew of the Month: for field teams who perform with excellence and unity
Public shoutouts, Slack praise, and peer-nominated awards

Because this work is hard. And it deserves to be seen.

A Mission Bigger Than Ourselves

We believe success isn’t just about what you do on the job — it’s about what you build around you.

That’s why we:

Sponsor school events like the local Jog-a-Thon
Show up in person to cheer kids on
Support causes that matter to our teammates and their families

At SumZero, we’re not chasing flashy growth. We’re building a stable, sustainable company that people are proud to work for — and proud to recommend to their neighbors.
