It’s 10 p.m. on a Wednesday in January. The temperature outside is -28°C. Your furnace has just broken down without warning.
The children are shivering in their beds. You call heating companies in a panic, but everyone is swamped. The earliest available appointment? In three days. The cost of an emergency repair in the middle of winter? Easily double the normal price.
This happens to hundreds of Montreal families every winter. Yet about 60% of furnace breakdowns could have been prevented with a simple preventive inspection in the fall.
In Montreal, where temperatures regularly drop below -30°C between November and February, your heating system is not a luxury. It is essential for your safety, health, and comfort.
Why a Pre-Winter Inspection Is Essential in Montreal
A heating system is like a car. You wouldn’t set out on a 5,000-km road trip without checking the oil, brakes, and tires. Why would you expect your furnace to run nonstop for six months without inspecting it first?
The numbers speak for themselves. According to data compiled by AirGreen and other experts in the field, uninspected systems are 40% more likely to break down during the winter.
These breakdowns always happen at the worst possible time. Never on a sunny Sunday afternoon in November when it’s still 10°C. No, they happen during the January cold snap when all the technicians are swamped and wait times get longer.
Montreal and Its Extreme Winters: Systems Under Pressure
Winter in Montreal is no joke. From November to April, your heating system runs almost nonstop for six full months.
Data from Environment Canada show that Montreal experiences an average of 52 days per winter when the temperature drops below -20°C. During these periods, your furnace or heat pump runs at full capacity for 18 to 20 hours a day.
Heat pumps, which are gaining popularity for their energy efficiency, have their limitations in our climate. According to tests conducted by Celsius and published in 2025, most residential models lose 30% to 50% of their efficiency when temperatures drop below -25°C.
At -35°C, some heat pumps simply stop working and switch to backup electric heating. If your system hasn’t been inspected and optimized before winter, this switch could lead to some unpleasant surprises on your Hydro-Québec bill.
Montreal’s older neighborhoods, such as Rosemont, Ahuntsic, and Verdun, often have homes with heating systems that are 15 to 25 years old. These systems have weathered many harsh winters. Without regular inspections, they become ticking time bombs.
Myth or reality? «A new system doesn’t need to be inspected.»
This is probably the most dangerous myth we hear. «My furnace is only three years old—no need to have it inspected.»
Wrong. Completely wrong.
Data from XpertSource published in 2025 reveals that 20% of heating system failures occur in systems less than five years old. How is this possible?
The initial installation wasn't perfect. The electrical connections were a little loose. The ducts weren't sealed properly. The airflow was never calibrated correctly. These minor flaws go unnoticed for a year or two, and then lead to a major breakdown.
Manufacturers' warranties often require annual maintenance to remain valid. If you don't have your new system inspected and it breaks down, the manufacturer may refuse to cover the repair. You've just lost thousands of dollars in coverage.
Here's the reality:
| Myth | Fact |
| New systems do not require inspection | 20%: Failures affect systems less than 5 years old |
| The inspection is too expensive | An emergency breakdown costs 3 to 5 times more than a preventive inspection |
| If things are heating up, that means everything's going well | A system may provide heat but consume 30% too much energy |
Have your system inspected—even if it's new—to maintain the manufacturer's warranty and avoid unpleasant surprises.

What a Comprehensive Heating Inspection in Montreal Covers
A truly professional inspection goes far beyond just taking a quick look and saying, «That looks fine.»
At Vortex Air, our inspection follows a five-step protocol developed in accordance with INVC standards and adapted to the realities of Montreal’s climate.
Step 1: Checking the Burners and Filters
We start by examining the heart of the system. For gas furnaces, we inspect the burners for corrosion, buildup, or necessary adjustments. Dirty burners reduce efficiency and increase carbon monoxide emissions.
Filters are checked and replaced as needed. A clogged filter forces the system to work harder, increases your electricity or gas usage, and can even cause overheating.
For heat pumps, check the outdoor unit. Debris that has accumulated over the summer—leaves, dirt—all of this can affect performance. Clean the coils and check the refrigerant level.
Step 2: Measuring Carbon Monoxide and Heat Output
This is the most critical step for your safety. We use certified combustion analyzers to measure carbon monoxide (CO) levels in the exhaust gases.
CO is a colorless, odorless, deadly gas. Every winter in Quebec, people die from carbon monoxide poisoning caused by faulty heating systems. A single crack in the heat exchanger can turn your furnace into a death trap.
We also measure the heat output to ensure that your system is producing the heat it should. A system that operates at only 70% of its rated capacity is costing you in efficiency without you necessarily noticing it.
Step 3: Inspection of the Ducts and Heat Exchanger
Hot-air ducts carry heat throughout your home. Leaks in the ducts mean you’re heating your walls, basement, or attic instead of your living spaces.
We visually inspect all accessible ducts. Disconnected sections, poorly sealed joints, damaged insulation—we note everything.
The heat exchanger is the most important and most expensive part of your furnace. Cracks or corrosion can allow combustion gases to mix with the air in your home. We inspect it thoroughly using cameras and mirrors to detect problems that are invisible to the naked eye.
Step 4: Energy Efficiency Report
At the end of the inspection, you will receive a detailed report on your system’s actual efficiency. We compare its current performance with its original specifications.
If your furnace, which has a rated efficiency of 95%, is now operating at only 78%, you deserve to know. That explains why your Hydro-Québec or natural gas bills have gone up.
The report includes photos of the inspected components, the measurements taken, and a clear assessment of the system's overall condition: excellent, good, acceptable, or in need of repair.
Step 5: Corrective Recommendations
We’ll wrap up with honest, prioritized recommendations. What needs to be done immediately for your safety? What can wait a few months but should be planned for? What is optional but would improve your comfort or save you money?
We never push unnecessary sales. If your system is working well, we'll tell you so frankly.
Standards and certifications required by the RBQ and the CMMTQ
In Quebec, working on heating systems isn't just a matter of goodwill. It's strictly regulated by law.
The Régie du bâtiment du Québec (RBQ) requires that any person or company that installs, repairs, or maintains heating systems hold the appropriate license. For gas systems, this is a Category 15.1 license.
Since Decree 438-2025, the requirements have become even stricter. Technicians must undergo continuing education and demonstrate their competence every three years.
The Corporation of Master Plumbing Mechanics of Quebec (CMMTQ) oversees heating and plumbing contractors. Members must adhere to high quality standards and maintain liability insurance.
The INVC (National Institute of Ventilation and Air Conditioning) certifies technicians specifically for maintenance and inspection of HVAC systems. This certification ensures that the technician is familiar with safety protocols, efficiency standards, and best practices.
At Vortex Air, all of our technicians are INVC-certified, and we are currently in the process of obtaining our NADCA certification, the international standard. We never let anyone who isn’t qualified work on your system.
Our RBQ-certified technicians inspect your system in accordance with Standard 2025. You have the peace of mind that the work is done correctly and in compliance with the law.
Costs and Cost-Effectiveness of a Pre-Winter Inspection
Let's talk about money, because that's often the first question people ask us.
A comprehensive heating system inspection in Montreal generally costs between 300$ and 600$, according to data published by Soumissions Québec in 2025. The price varies depending on the type of system (gas furnace, electric furnace, heat pump, hybrid system) and its complexity.
It may seem expensive until you compare it with the alternatives.
An emergency furnace replacement costs between 4,000$ and 8,500$ for a standard residential system. If the breakdown occurs in the middle of winter, add 20% to 40% for emergency fees and reduced availability.
A major emergency repair (heat exchanger, fan motor, circuit board) can easily cost between 8,00$ and 2,500$. Not to mention the uncomfortable nights spent waiting for the technician to arrive.
But the real return on investment comes from energy efficiency. A well-maintained system consumes 20% to 30% less energy than a neglected system.
Did you know? A 450$ inspection can save you the equivalent of three months’ worth of heating costs during the winter!
For an average home in Montreal that spends 1,800$ on heating each winter, a 25% improvement in energy efficiency translates to 450$ in annual savings. The inspection pays for itself in one year, and every year after that is pure profit.
Not to mention the peace of mind that comes from knowing your family will be safe and warm all winter long.
Signs That Your Heating System Needs an Urgent Inspection
Some warning signs should never be ignored. Your heating system is trying to tell you something—you just have to know how to listen.
If you notice one or more of these symptoms, call immediately to schedule an inspection. Don't take any chances with your family's safety.
Unusual noises: It’s normal for a heating system to make noise. But certain sounds can indicate serious problems. A screeching metal noise could mean a worn-out motor bearing. A loud bang when starting the engine suggests a buildup of gas before ignition (very dangerous). A high-pitched whistling sound often indicates a leak or a pressure problem.
Suspicious odors: The smell of natural gas (like rotten eggs) requires immediate action. Leave the house, don’t turn on any lights, and call Énergir and the fire department. A smell of burning or melting plastic may indicate overheating or an electrical problem. Even a simple smell of dust that persists after the first few days of use warrants a check.
Low or uneven airflow: Are some rooms staying cold while others are overheated? Does the airflow coming from the vents seem weak? This could be caused by clogged ducts, a faulty fan motor, or a poorly balanced system.
Short, frequent cycles: Does your furnace turn on, run for 2–3 minutes, turn off, and then restart 5 minutes later? These short cycles indicate a problem with the thermostat, a clogged filter, or a dirty heat exchanger. This causes premature wear on the system and increases your energy consumption.
Rising Energy Bills: If your natural gas or electricity usage has increased by 20% or more for no apparent reason (same cold winter, same house, same habits), your system is probably losing efficiency.
Yellow or orange flame: For gas furnaces, the burner flame should be bright blue with just a hint of yellow. A flame that is mostly yellow or orange indicates incomplete combustion, which produces carbon monoxide.
Marie-Claude, the owner of a duplex in Rosemont, called us last November after noticing a strange odor and popping noises coming from her 18-year-old furnace. The inspection revealed cracks in the heat exchanger and dangerous levels of CO. «I almost didn’t do anything, telling myself it could wait until after the holidays,» she told us. «It could have cost us our lives.»

Heating Assistance Grants and Programs in Montreal
Upgrading your heating system doesn't have to break the bank. The government and Hydro-Québec offer several substantial assistance programs.
The rules change regularly, so it's important to check the current eligibility requirements. But here's what was available in early 2025.
The Program LogisVert Hydro-Québec offers grants of up to 5,000$ for the installation of energy-efficient heating systems. This includes central heat pumps, geothermal systems, and thermodynamic water heaters.
To be eligible, your home must be located in Quebec and must be heated primarily by a less efficient system (oil, propane, or electric resistance heating). The installation must be performed by a certified contractor.
The program covers between 20% and 50% of eligible costs, depending on the type of system chosen. For a 12,000$ central heat pump, you could receive between 2,400$ and 6,000$ in assistance.
The Program Heat Green The Quebec government’s program, which offered up to 1,625$ for the replacement of oil-fired systems, ended in the summer of 2025. But new programs are announced regularly, so it’s worth checking.
Municipalities in the metropolitan area (Montreal, Laval, Longueuil) sometimes offer their own incentives for energy-efficient renovations. The City of Montreal offers a tax credit for certain energy-efficiency improvements.
Rénoclimat It remains the go-to program for obtaining a comprehensive energy assessment of your home. The assessment costs about 300$, but it identifies all possible improvements and makes you eligible for grants of up to 10,000$ for major renovations, including heating, insulation, and doors and windows.
For low-income households, the program Efficient Heating and Air Conditioning can cover up to 80% of the costs of replacing an old, inefficient heating system.
The reality is that navigating all these programs can be complicated. Eligibility requirements, forms, and mandatory inspections—all of this discourages many people who would otherwise be eligible for thousands of dollars in assistance.
Take advantage of a subsidized inspection—our team will guide you through the process for free in helping clients maximize the available financial assistance. We have helped dozens of clients secure grants totaling more than 150,000$ over the past two years.

FAQ – Everything You Need to Know About Heating System Inspections Before Winter
How often should you have your furnace inspected in Montreal?
We recommend a thorough inspection every year, ideally in September or early October before the first cold snap. For systems that are more than 15 years old or have had problems in the past, two inspections per year (in the fall and spring) are preferable.
What is the difference between maintenance and inspection?
The service includes basic maintenance tasks: changing filters, cleaning burners, and lubricating moving parts. Inspection goes a step further: we test performance, measure CO emissions, look for signs of wear or imminent failure, and assess overall energy efficiency.
What are the risks of carbon monoxide?
Carbon monoxide (CO) is an invisible, odorless toxic gas produced by incomplete combustion. It causes headaches, nausea, and confusion, and can be fatal at high concentrations. Every winter in Quebec, people die from CO poisoning. An inspection can detect potential leaks before they become dangerous.
Can I perform a basic check on my own?
Yes, you can perform some simple checks: change the filter, listen for unusual noises, make sure all the vents are working, and test your CO detector. But a thorough inspection requires specialized tools and expertise that only a certified professional possesses.
Are inspections required under the RBQ?
The RBQ does not require mandatory annual inspections for single-family homes. However, owners of rental properties have a legal obligation to maintain their systems in good condition. Many manufacturers’ warranties require annual maintenance to remain valid.
How can I tell if my heat pump is working efficiently at -25°C?
On a very cold day, check to see if the outdoor unit is frosting up excessively, if it defrosts too often (more than 2–3 times a day), or if the electric auxiliary heater is running constantly. A professional inspection that includes a measurement of the coefficient of performance (COP) will provide you with accurate data.
Are there any grants available to replace an old system?
Yes, Hydro-Québec’s LogisVert program offers up to 5,000$ for the installation of heat pumps and energy-efficient systems. Other programs may be available depending on your situation. We’ll help you identify all the available financial assistance and fill out the forms—free of charge.
When is the best time to schedule an inspection?
September and October are the perfect months. Technicians are less busy than in the middle of winter, you have time to make the necessary repairs before the cold weather sets in, and you avoid the November rush when everyone calls at the same time as soon as the first cold snap hits.
