Protect your home and comfort by avoiding HVAC scams in Montreal, Laval, Longueuil, North Shore and South Shore
In the world of residential and commercial HVAC, scams involving fake air exchanger technicians are unfortunately becoming more common—especially in urban areas like Montreal, Laval, Longueuil, the North Shore, and the South Shore. At AirGreen, we frequently get calls from worried customers who’ve been approached by individuals pretending to be specialists. These impostors often claim to represent a major company, offer a free inspection, or announce some supposed “safety emergency.” These scams not only cost money—they can also compromise your system’s safety and performance.
In this article, we’re sharing real field experience, concrete tips on how to recognize a fake HVAC technician, and mistakes to avoid when hiring someone to install, service, or repair your air exchanger.
Fake HVAC technicians: a real and growing threat
These scammers are often well-dressed, may carry a fake ID badge or falsified documents. They play on urgency, fear, or lack of technical knowledge to get access to your home. Once inside, they claim to have found a serious issue, then push for an immediate repair—often unnecessary—at an inflated cost.
We’ve seen several cases in Montreal and Laval where homeowners paid hundreds of dollars for something as simple as a filter change or parts that were never even installed. On the South Shore, one customer’s air exchanger was actually damaged by a botched “repair,” leading to the need for a full replacement.
1. How to spot a fake HVAC technician
Here are the most common red flags:
-
No clear identification: The technician doesn’t present an official employee badge or drive a clearly marked AirGreen or other reputable local company vehicle.
-
No prior appointment: The technician shows up unannounced, often claiming “we’re doing routine inspections in your neighborhood.”
-
Fear tactics: They immediately talk about “mold hazards,” “fire risks,” or “non-compliant ventilation.”
-
Cash-only payments: They refuse traceable payment methods like credit card or bank transfer.
-
Immediate pressure: They push you to agree to on-the-spot repairs, not giving you time to think or get a second opinion.
2. How to avoid getting scammed? Our professional advice
At AirGreen, here’s what we recommend to protect yourself:
-
Check ID: Always ask for photo ID and the exact name of the company. Our technicians wear branded AirGreen uniforms and drive clearly marked vehicles.
-
Call the company directly: If you didn’t book an appointment yourself, call customer service to confirm the visit.

Don’t fall for urgency: No legitimate technician will force you to make an immediate decision under pressure.

4. Real customer story: A close call in Boucherville
A client recently contacted us after being visited by someone claiming to be a “government inspector” for his air exchanger. The man said the unit was non-compliant and offered to replace it on the spot for $1,800. Luckily, the customer called our office before signing anything. When a real AirGreen technician came to inspect the unit, it was working perfectly. Result: no repairs needed.
5. When should you call a real HVAC expert?
You should consult a certified professional when:
-
You notice odors, humidity, or strange noises from your ventilation system.
-
Your unit doesn’t seem to be ventilating effectively anymore.
-
You want to check for grant eligibility or plan a preventive annual maintenance.
-
You’re moving into a new property and want to inspect the existing ventilation system.
6. What you risk with a fake technician
Beyond the financial loss, the risks are serious:
-
Damage to your system: poor handling, unnecessary part replacements, or needless ductwork drilling.
-
Voided warranty: If someone unqualified touches your system, your manufacturer’s warranty could be canceled.
-
Compromised safety: Uncertified changes can affect air quality—or even cause leaks.
