7-step inspection process
1. Preliminary interview with the customer
Discussion of problems observed, system history, recent renovations, respiratory health issues in the building.
2. External system inspection
Check outdoor unit, fresh air inlets, exhaust outlets and general condition of visible components.
3. Analysis of mechanical equipment
Monitoring of the furnace or heat pump, condition of the coils, fan operation, and checking of electrical connections.
4. Camera inspection of all ducts
Systematic exploration of every branch of the network, with full photographic and video documentation.
5. Performance tests and measurements
Record air flow, pressure, temperature and humidity at various points in the system.
6. Samples for analysis (if necessary)
Samples of dust, air or suspect materials sent to a certified laboratory for microbiological analysis.
7. Compilation of detailed report
Complete report with photos, prioritized recommendations and estimated costs of correction.

FAQ – Comprehensive Inspection of Ventilation Systems
Why is it important to conduct a thorough inspection before cleaning or repairs?
Honestly, because we see too many people wasting money on nothing. In the field, we’ve inspected systems that others wanted to “clean out immediately,” when the real problem was a loose pipe in the wall. A thorough inspection prevents you from treating the symptoms instead of the cause.
What is most commonly found during a thorough inspection?
In most homes in the Greater Montreal area, you’ll find a combination of three things: excessive dust buildup, air leaks at the joints, and sections of ductwork that haven’t been cleaned since the house was built. And sometimes, to your surprise, you’ll find animal nests or ductwork that’s been crushed during past renovations.
Can an inspection really explain why electricity bills are too high?
Yes, very often. We’ve seen systems lose 20 to 30 % in efficiency due to invisible leaks or poor balancing. When air doesn’t circulate properly, the furnace or heat pump works harder than it needs to… and you’re the one footing the bill.
Is a camera in the ducts really useful, or is it just impressive?
It’s essential. Without a camera, we can only guess. With a camera, we know for sure. Several customers were convinced their ducts were “clean” until they saw the images. It completely changes the conversation—and, more importantly, the decisions that need to be made.
How long does a full inspection at a private residence take?
For a standard home, it takes between 2 and 4 hours. And no, we don't rush. An inspection done too quickly means some areas won't be checked. We'd rather take the time than have to come back later to explain why a problem was missed.
Is a home inspection really worth it before buying a house?
Absolutely. We've helped several buyers who were able to renegotiate the price after seeing the system's actual condition. Contaminated or improperly installed ducts can end up costing a lot after the purchase. It's better to know that before signing.
Do you often find mold during inspections?
It happens more often than people realize, especially in basements and older homes. And it’s not always visible to the naked eye. That’s why we measure humidity and sometimes take samples. Ignoring this is putting your health at risk.
What is the biggest mistake you see homeowners making?
Waiting too long. People put up with odors, dust, or poorly heated rooms for years. By the time an inspection is finally conducted, the damage is more extensive and the repairs cost more than a simple preventive maintenance visit.
Does an inspection automatically lead to costly repairs?
No, and that’s a myth. In many cases, our recommendations are simple: adjust the seals, replace an inadequate filter, or correct an airflow imbalance. The purpose of the inspection is precisely to prioritize, not to sell unnecessary work.
What is the practical purpose of the detailed inspection report?
This is your roadmap. It lists the issues in order of priority, complete with supporting photos and realistic estimates. Many clients use it to plan their projects over 2–3 years instead of doing everything all at once.
How often is a comprehensive inspection recommended in Quebec?
For residential systems, every 3 to 5 years, or as soon as an unusual problem arises. For commercial systems, more frequently. Given our climate—humidity, salt, and extreme temperature fluctuations—systems age faster than you might think.
Why choose Ventilation Vortex Air for your inspection rather than just anyone?
Because that’s what we do every day here, with local buildings. We know Montreal homes, poorly ventilated condos, and systems cobbled together over the course of renovations. And above all, we tell you the truth—even when that means “you don’t need to do anything right now.”.
