How Coastal Air Duct & Vent Cleaning Greater Youngstown Was Born in Youngstown
It was a Tuesday in March 2008, and we were standing in a ranch house on the south side of Youngstown, watching a woman named Doris write a check for $890. She was 74 years old, living on Social Security, and her air ducts hadn’t even been cleaned. The company before us—one of those big-name outfits with the catchy jingles—had sent a kid with a shop vac and a bottle of purple spray. He’d fogged her basement with a “sanitizer” she didn’t ask for, poked a camera into one vent, and declared the job done in 47 minutes. Doris knew something felt wrong, so she called us for a second opinion. We put our own camera through her system. The ducts were still packed with construction debris from 1987.
That night, we sat in our truck outside of a now-closed diner on Market Street, drinking coffee that tasted like burnt metal, and made a decision. Youngstown deserved better. Not flashier. Not cheaper. Just honest. We started Coastal Air Duct & Vent Cleaning Greater Youngstown the following month with a used Rotobrush machine, a borrowed trailer, and a rule we’ve never broken: we’d rather explain why something costs what it costs than hide behind a lowball quote and pile on fees later. Doris became our first regular. She sent us her neighbors, her church group, her sister in Boardman. She’s gone now, but we still drive past that house sometimes. The new owners have our magnet on their fridge.
Mark Thompson’s Personal Connection to the Air Duct Cleaning Trade
Mark didn’t stumble into this work—he was practically raised in it. His uncle ran a small HVAC shop on the west side of Youngstown through the 1980s and 90s, back when the mills were still humming and every house in Campbell ran on forced air. Mark was twelve the first time his uncle let him hold a borescope. He remembers the exact sensation: the rubber grip was warm from his uncle’s hand, the screen was grainy black-and-white, and the inside of that duct looked like another planet—gray fur, glittering flakes of old paint, a lost pencil from 1974. “Every house has a story in there,” his uncle said. Mark felt that in his chest like a fact he’d always known.
He spent his teenage summers crawling through crawlspaces in Girard and Struthers, learning to read a duct system like a map. The smell of old fiberglass still takes him back—dry, slightly sweet, the scent of someone’s forgotten attic. After his uncle retired, Mark worked for a few bigger companies. The money was better, but the work felt hollow. He’d see technicians skip whole trunk lines, falsify before-and-after photos, sell “mold remediation” to people with perfectly clean systems. It made him physically tired in a way that twelve-hour days in cramped mechanical rooms never had.
What gets Mark out of bed now isn’t the paycheck. It’s the moment when a homeowner in Austintown or Howland Center sees their own duct footage for the first time—the genuine surprise, sometimes the disgust, sometimes the relief of knowing what’s actually going on back there. He’ll tell you straight: if he weren’t doing this, he’d probably be restoring old motorcycles or teaching shop class somewhere. He likes making broken things work right again. He likes the visible difference. Seventeen years in, he still goes on maybe a third of the jobs himself, especially the tricky ones—old Victorians in Canfield with original ductwork, or the post-war ranches in Champion Heights where every system is just slightly wrong in its own unique way. He can’t help it. He wants to see the thing himself.
Meet Mark Thompson — The Person Behind Every Job
Mark Thompson is the Owner & Lead Technician at Coastal Air Duct & Vent Cleaning Greater Youngstown. He’s state-licensed, insured & bonded, and trained on equipment from Rotobrush and Abatement Technologies, though he’ll be the first to tell you that the machine matters less than the person running it. Over 17 years, he’s cleaned ducts in everything from century-old farmhouses in Hubbard to new builds in Warren, and he’s developed a reputation for fixing problems other companies walk away from—collapsed flex duct, improperly sealed plenums, systems that have never been balanced since installation.
What separates Mark from a corporate franchise technician is simple: his name is on the door, and his cell number goes to his actual pocket. He’s also stubborn about continuing education—new NADCA standards, updated indoor air quality research, better containment methods. Outside of work, he’s the guy who shows up early to help set up for the Little League opening day in Boardman because his neighbor coaches. He believes in being where you say you’ll be, doing what you said you’d do. If you hire Coastal, Mark’s personal commitment is this: you’ll know exactly what we found, exactly what we did, and exactly what it cost before we pack up a single tool.
Our Promise to Youngstown Homeowners
Honest pricing, always. We don’t do “whole-house specials” that mysteriously triple once we’re in your basement. Our estimates are free, detailed, and binding. We learned this the hard way in our first year, when a supplier error cost us $400 on a job in Niles. We ate the loss. The homeowner still calls us every spring.
Quality equipment and parts. We use Rotobrush systems and Aprilaire filtration products because we’ve tested the alternatives and watched cheap equipment fail in real Youngstown homes. When we recommend a UV light or a media filter, it’s because we’ve seen it solve a specific problem—not because it’s the upsell of the month.
We stand behind every job. If you’re not satisfied, we come back. No paperwork, no runaround. In 2021, a customer in Campbell smelled something odd two days after we left. Turned out to be unrelated—a dead mouse in a wall—but we checked her entire system again, no charge, because she needed to trust her air again. That’s the policy.

These credentials matter because inviting someone into your home to work on your air system requires trust.

Insurance and bonding means if something goes wrong—a scratched floor, a damaged vent, an injury on your property—you’re not left holding the bag. And those 661 reviews? They’re not from a national call center routing jobs to subcontractors. They’re from your neighbors in Warren, in Howland Center, in Girard, people who watched us work in their actual homes and felt good enough about it to say so publicly.
Rooted in Youngstown
We’ve never considered relocating to Columbus or franchising into Pittsburgh. Youngstown is where Mark’s family put down roots, where his kids went to school, where he still catches the Canfield Fair every August and grabs breakfast at the same spots on the south side. We’ve cleaned ducts after floods in the neighborhoods near Mill Creek Park, helped Boardman families prepare homes for new babies, and worked with property managers in downtown Youngstown restoring historic buildings. This isn’t our territory—it’s our community. When you call (866) 952-5794, you’re not reaching a dispatch center in another state. You’re reaching people who know why the 680 bridge matters, who remember when the downtown was different, who plan to be here when it’s different again.
