NADCA Certified Since 2000 — 25 Years in the Field — Still Runs Jobs Himself

Teaching service businesses how to succeed at indoor air quality.

NADCA certified since 2000. Twenty-five years in the field. Still runs jobs himself. Trained restoration companies, HVAC shops, waterproofing firms, and property management teams nationwide.

Duct cleaning is the add-on most service companies already have the clients for. Restoration, HVAC, janitorial, waterproofing, property management — you are already in the building. Three days to add the trade without buying the wrong truck.

$5,000plus travel, anywhere in the United States

Companies trained routinely save thousands in wrong equipment purchases.

Technicians leave having actually cleaned a system, not watched slides.

Post-training support included — techs keep my cell for FaceTime from the jobsite.

Mike Keller

Twenty-five years in the industry before the janitorial company. NADCA certified in 2000. The hard-knocks version: trial, error, and every expensive machine you should not buy first. He has trained restoration companies, HVAC shops, waterproofing firms, and property managers to add air duct cleaning without lighting money on fire.

He still runs jobs. The course is at your location — Connecticut or he travels — so your technicians learn on your building, not a rented classroom.

Managed and sold over a hundred million dollars in commercial construction and restoration projects — estimating, project management, deal-closing, and field operations.

From the field

What crews say after.

“I loved the training so much I have Mike out periodically to train new managers.”

Corey · SERVPRO of Boston

“We used Mike for training and we still use him on large commercial projects to train new crews on site.”

Paul · SERVPRO of Connecticut

“Duct cleaning was the obvious add-on. Three days with Mike saved a boatload of money in mistakes we would have paid for later.”

Brad · Basement Systems, Hardin County, Kentucky

Another passion

Teaching businesses how to succeed — on purpose.

Duct cleaning is an add-on, not a new company. Most service businesses already have the clients: restoration, HVAC, waterproofing, janitorial, property management. They keep asking about air quality. You keep sending the work down the street.

Mike’s other passion is teaching those crews how to keep the work — the right equipment list, a real job on your building, and a plan for the first ten invoices. You do not start with a $40,000 truck. You start with people who already trust you.

Day 1

The business, not the toy truck

Indoor air quality in plain language. How duct work actually moves air in houses, offices, and light commercial. NADCA-informed standards without the seminar fluff. We map which of your existing clients should hear this first — restoration, janitorial, waterproofing, property management, HVAC — so you sell the add-on before you buy a box truck.

Day 2

Hands on your building

We clean your office or a house you control. Registers, returns, flex, trunk lines, and the mistakes that shred equipment. You get the shopping list before class so the machines are in the room, not in a catalog. Technicians run the job. Mike stands over the shoulder and stops the expensive habits on day one.

Day 3

Crew, price, and the call after you leave

Job costing, crew roles, close-out photos, and what to say when a customer asks if the mold is “gone.” You leave with a playbook. Techs keep Mike’s cell for FaceTime from the jobsite — that follow-through is included, not a upsell.

Common sense. Work smart, not hard.

  • Do not start with a $40,000 truck.

    Most service companies already have vans, clients, and a reputation. Air duct cleaning fails when someone buys a shiny negative-air rig before they have ten booked jobs. We start with a list you can actually afford, then grow the fleet from paid work.

  • Sell it to people who already trust you.

    Restoration, janitorial, waterproofing, and HVAC already walk into dirty systems. Cold-calling “free duct inspections” is how rookies burn Saturdays. Your base is the market.

  • Clean source, not just the register.

    Wiping a vent and calling it a duct clean is how you get chargebacks. We teach inspection, containment, and the difference between dust you can see and dust that recirculates after you leave.

  • Document like an insurance job.

    Before/after, static pressure when it matters, and a written scope. Indoor air quality is a health conversation. If you cannot explain what you did, do not invoice it.

  • Pay the crew like you mean it.

    This is dirty, technical work. The companies that last are the ones who do not treat techs as disposable. Mike has run crews for 25 years. We talk about pace, safety, and not wrecking a homeowner’s Sunday.

What you walk away with

  • A complete equipment and supply list before day one — so you do not overbuy.
  • Hands-on cleaning of your shop or a house you control, with your technicians on the tools.
  • A customized plan from a call or visit before class, whether you are in Connecticut or out of state.
  • Travel, lodging, and expenses quoted up front when Mike comes to you. No surprise invoices.
  • Post-training support: techs FaceTime or call Mike from the job at no extra charge.
  • English and Spanish speaking instruction when your crew needs it.
  • Most of all: you skip the unused machines and the first year of preventable mistakes. Companies Mike has trained routinely save thousands of dollars in equipment they would have bought wrong, and days of labor they would have spent redoing jobs.

Schedule the three days.

$5,000 for the three-day course, anywhere in the United States, plus actual travel (airfare, lodging, ground). Travel is quoted before you book — no padded extras after the fact.

The fee is the cheaper line on the invoice. Buying the wrong vacuum, the wrong brushes, and a truck you do not need is how service companies lose five figures before the first paid duct job. This course is built to stop that: the right list, the right sequence, and hours you will not spend undoing bad habits on a customer’s house.

Connecticut companies train at your location. Everywhere else, Mike comes to your facility. Tell him the trade you already run and how many techs will be in the room.
