Boiler & Chiller Killers HVAC demolition specialists · Denver

About

Two owners. One crew. Built to remove what was built to last.

Boiler & Chiller Killers is a Colorado LLC founded in 2017 and run by two working managing members who are also brothers. One of us is on the floor of every job. This is who we are and how we got here.

How it started

A truck, a torch, and a reputation for showing up

Gadge has been taking boilers apart since 2011, first under a mentor, then on his own. He founded BCK in 2017 with a work truck, a cutting rig and the habit of answering the phone. The first years were residential boilers and water heaters, then small commercial, then the plants got bigger: cast iron sectionals by the dozen, firetubes, chillers, and a 52-million-BTU boiler in 2022 that took weeks and that you could have driven a truck through.

Saber worked alongside him on and off through those years as hired labor, between a career in aerospace that ran from the shop floor to quality engineering and program management. In early 2026 he came in as the operations partner. On May 1, 2026, standing in a historic building downtown after finishing a job, the two of us decided to make it a real partnership. The operating agreement followed in June: fifty-fifty, two managing members, one company.

The owners

Skillsets that complement, not compete

Managing Member · Field Operations & Demolition

Gadge Bell

Founded BCK in 2017. Cutting boilers since 2011: thousands of removals, from residential water heaters to a 52-million-BTU firetube. Leads every jobsite, sets the sequence, makes the first cut and the last, and outworks everyone on the floor. OSHA 30. Rigging and crane certifications in progress, EPA 608 next.

What he brings that can't be trained quickly: fifteen years of knowing where the weight is, where the old insulation hides, which section fights back, and how to get a piece through a door that was framed before the boiler went in.

Managing Member · Business Operations & Engineering

Saber Dean

Started working on a cattle ranch at nine and worked labor jobs until twenty. Went into aerospace and worked up through it: quality engineering, AS9100 lead auditor, first-article inspection and certification documentation on flight hardware, program management. Worked as hired labor beside Gadge many times over the years before joining as the operations partner in 2026. OSHA 30. EPA 608 Universal.

He leads business development and technical operations: the estimate, the contract, the technical analysis and rigging plan, and the closeout package with traceability from the first photo to the last invoice. On the floor when the job needs him, hammer in hand, documenting the whole way.

How we work

What the aerospace side does to a demolition company

Field mastery on one side, quality-system discipline on the other. Together they look like this on your job.

An owner on every job

A BCK principal provides working field supervision whenever field operations are underway. That is in our contract, not just on this page.

Plan before the torch

Weights from nameplates and photos, checked with a tape at the walk. Load paths, sequence and fire discipline decided before the first cut.

Cleaner than we found it

Floors protected, room swept, photographed. Every job, including the same-day ones.

Document it like flight hardware

Scope verification, captioned photo record, recovery documentation, certification of completion. Delivered with the final invoice.

  • 0 lost-time incidents since the company was formed.
  • 450+ jobs since 2017.
  • 18 jobs in the first quarter of the partnership, eleven of them commercial contracts.
  • If it needs removal, we remove it.

Built with intent

Family is everything. Not just the one you're born with.

We built this company from less than nothing, and we know exactly what it is for. It is how we take care of the people we're responsible for, and how we show the kids in our lives that hard work in the right direction gets you somewhere. A lot of people we grew up with never got that chance.

So we run BCK the way we try to run everything: with intent. Do the hard thing because it is the right thing. Hire the neighbor who wants to learn before the stranger who wants a check. Show up for our mothers, our church, and the block we live on, whether that means a neighbor's truck that won't start, a heavy thing that needs moving, or a gutter that needs cleaning. Rough around the edges, strong together, and honest about both.

None of that is a marketing line. It is why the room is clean when we leave.

The crew

Orange shirts, white hard hats, same rules

Beyond the two of us, BCK runs a crew that scales with the job: hands we have worked with for years, trained our way and covered under our insurance, plus vetted labor when a schedule needs more of us. Everyone on a BCK site is OSHA-trained at a minimum, briefed every morning, and held to the same standard for protection, fire discipline and cleanup. Crew members are introduced here by name as they join the company full time.

Where we're headed

Bigger plants, same standard

The largest boiler we have removed is 52 million BTU. The largest we have bid is 80. The plan for the next two years is more of the same, done the same way: rigging and crane certifications for both owners, a second EPA 608 certification, air-quality credentials, and the certified payroll and coverage depth that institutional and government work asks for. Front Range first, the rest of Colorado for the right job, and neighboring states when it is worth the drive.

Boilers. Chillers. Mechanical systems.
We make them disappear.
