In the ever-evolving world of HVAC, standing still is never an option — especially when you’re a contractor operating in one of the most regulated, language-locked markets in North America.
That’s why Anthony Woo and his company, Climatisation ACG, stand out. Based in a modest office just outside Montreal, Anthony has grown a small startup into a thriving business grounded in education, High-Performance HVAC™ testing, and relentless customer service.
What’s even more remarkable is how he’s done it: with unbranded trucks, zero marketing budget, and a team made up almost entirely of HVAC newcomers.
“None of my guys had prior experience when they joined Climatisation ACG,” Anthony explains. “We’ve got former tattoo artists, gamers, musicians, even a precious metal trader on staff. Our entire crew has been built from the ground up.”
From Helper to High-Performance Leader
Anthony Woo’s HVAC journey began two decades ago as a field helper. He worked shoulder to shoulder with his future business partner, Kar Young Tom (also known as KYT), for 16 years before launching Climatisation ACG.
“We knew each other’s work ethic. We’d done 60-to-80-hour weeks together. So, when it came time to start our own thing, there was no hesitation,” says Anthony.
That mutual trust paid off. In just three years, Climatisation ACG surpassed its five-year revenue goal, achieving $1.3 million in annual sales. Anthony says they hit their seven-figure target two years ahead of schedule.
“It completely changed the way I view our potential. Now, I’m realigning everything to focus on long-term sustainability and consistent quality,” he adds.
That means he is concentrating on internal consistency, not just growth.
Customer Service Above All
For Anthony Woo, customer service isn’t a department — it’s the business model. “I tell people we don’t sell machines — we sell service,” he says.
That mindset has earned ACG nearly four straight years of perfect five-star reviews on Google and Facebook.
“We got dinged once by someone who didn’t use our service because they didn’t like our pricing. It’s like giving a Michelin-star restaurant one star because the menu is too expensive. But other than that, it’s been all five stars.”
Anthony’s approach to service is proactive and tech-forward. He’ll often walk homeowners through a basic diagnostic or maintenance task over messaging before rolling a truck.
“If I can save someone $240 by helping them clear a clogged drain line remotely, I’ll do it. It’s about building trust, not padding invoices.”
No Labels, Just Results
Despite Climatisation ACG’s success, the company still operates with unbranded trucks and no website — something Anthony plans to change with a complete rebrand later this year.
“When we started, the logo was just a stock image of two blue-collar workers,” he says. “It served its purpose. But now that we’re moving into the next phase of growth, we’re ready to build a brand that reflects our values and our performance.”
Such a lack of traditional marketing hasn’t held them back. Word-of-mouth, social media, and community engagement keep Climatisation ACG booked out three to four weeks at a time.
