If you’re a top-performing technician, installer, service plumber, or energy pro who’s tired of chaos, corner-cutting, and vague promises—Denoco Kingston is building the opposite: a premium, systems-driven company where the craft is respected, the work is documented, and the people doing the work share in the results.
Apply if you want to build something better and be part of a team that treats you and your family's health and time like it matters.
LEAVE IT BETTER
We believe good business starts with trust.
Honest advice. Transparent pricing. Quality workmanship. Relationships that last.
We’re building Denoco around a simple idea: leave every home, every customer, every employee, and every community better than we found them.
We decide with a simple test. Are we adding value to this situation? If the answer is no, we do not do it.
Who this is for (and who it isn’t)
You’ll probably love it here if you are:
- A technician or installer who takes pride in clean work and clean explanations
- Calm under pressure, methodical, and allergic to sloppy installs
- The kind of person who wants to grow into leadership or ownership over time
- Ready for a shop that measures outcomes and improves the system continuously
This won’t be a fit if you want:
- “Good enough” installs with no documentation
- To wing it without checklists, commissioning, or communication
- To blame dispatch/customers/other techs instead of fixing root causes
Why Denoco
The home energy world is changing fast—heat pumps, solar, net-zero standards, better documentation, higher expectations. The companies that win the next 30 years will be the ones that can deliver high-performance systems reliably, affordably, and at scale—without burning out their people.
Denoco is positioned to ride three waves at once:
- The energy transition: modern HVAC + home energy is becoming the baseline.
- The talent war: the best tradespeople will choose companies that offer growth, health, and a real future—not just a paycheque.
- The systems edge: AI, automation, and CRM-driven operations remove the admin drag that makes most shops feel chaotic.
This isn’t “corporate.” It’s a better trades model: built on craft, transparency, and capability.
What we’re building
Our promise to technicians
AI does the admin, so we don't carry the overhead. That money goes into pay, training, your health, your retirement, and a youth program in Kingston.
And you see all of it: every job's numbers, the company's books are open.
Most shops eat up those savings. We're showing how they can be used more efficiently.
The Denoco Difference
We’re building a company where:
- Transparency is real: clear scopes, clear expectations, clear feedback loops.
- Health comes first: physical, mental, and financial health is part of the model.
- Shared wealth is the destination: the people who do the work share in the results as the company grows.
- Accountability is supportive: high standards, strong training, and calm execution, without blame culture.
Denoco is a school as much as it is a business. People should leave better than they arrived.
My Values are Our Values
- Radical honesty: we say what’s true, even when it’s uncomfortable.
- Transparency: the numbers and the outcomes aren’t hidden.
- Health first: we don’t build a business that breaks people.
- Compassionate accountability: support + standards.
- Service beyond expectation: do it right, do more than expected, every time.
- Community loyalty: serve where we live and work.
- Shared wealth: results are shared with the people producing them.
What you can expect (day-to-day reality)
- Clear job scopes and realistic timelines
- Strong documentation culture (photos, notes, commissioning)
- Support that reduces friction doing the job right (process, tools, systems)
- A path to more: training, leadership, and long-term upside as the model scales
