Winter is approaching, and you know what that means: temperatures will drop, the wind from Lake Saint-Louis will blow hard, and your heating system will run nonstop for months. But here’s the question: is your system ready?
In the western part of the Island—from Pointe-Claire to Dorval, including Kirkland and Beaconsfield—we face a unique challenge. Our homes are often older, our winters are damp because of the lake, and our energy bills keep rising every year. Regular maintenance of your heating system isn’t just another expense. It’s an investment that prevents costly breakdowns, lowers your bills, and protects your family.
At Vortex Air, we’ve been serving the West Island for over 10 years. We know your homes, your systems, and the specific challenges you face. In this article, we’ll explain why maintenance is so important here, how much it really costs, and how to make the right choices for your home.
Why Heating Maintenance Is Essential on the West Island
Let's be honest: many homeowners wait until there's a problem before calling. Is their furnace making noise? They turn up the thermostat. Is their electricity bill going up? They tell themselves that's normal in the winter.
But in our region, this approach can be expensive. Really expensive.
The unique context of the West Island (older homes + wet winters)
Here’s a fact that few people realize: about 58 % of the homes on the West Island are over 40 years old. These homes often have original or partially upgraded heating systems. They also have insulation issues typical of homes built in the 1970s and 1980s.
The wind from Lake Saint-Louis is beautiful to watch, but it brings humidity and causes significant heat loss. Your walls, your windows, your semi-basements—all of these work against you when it’s -20°C outside.
When your heating system has to compensate for these losses, it works harder. It wears out faster. And if it hasn't been maintained, it eventually breaks down—often on a Sunday evening in the middle of a storm.
We've seen this happen dozens of times. A customer in Beaconsfield called us in an emergency one Saturday in January because his old gas furnace had just broken down. Cost of the emergency repair: 850 $. If it had been serviced every fall, we probably could have prevented this.
Rising Energy Costs: Why Maintenance Pays Off
Hydro-Québec raised its rates by 3 % in 2025. For those who heat with oil or natural gas, bills have risen even more—we’re talking about an additional 150 $ per winter for an average home.
Now, imagine that a simple annual maintenance check could save you between 10 and 15 % on these costs. It’s not magic. It’s just efficiency.
A well-maintained system uses less fuel. It heats more efficiently. It wastes less. Over the course of a full season, this can amount to savings of between 100 and 200 $. Maintenance pays for itself.
Common Myths in the West Island (to Debunk)
We often hear these three myths:
Myth #1: «My smart thermostat adjusts automatically, so it doesn’t need any maintenance.» False. A smart thermostat can optimize your heating schedule, but it can't do anything if your burner is clogged or your ducts are blocked.
Myth #2: «Heat pumps don’t work when it’s -30°C.» That used to be true for older models. But modern heat pumps operate efficiently down to -30°C, with a coefficient of performance (COP) of 200 to 300. However, they must be serviced annually to maintain this performance.
Myth #3: «If my system works, then it’s fine.» It’s like saying, «My car still runs, so I don’t need to change the oil.» Your furnace may be running, but it could be wasting energy, emitting carbon monoxide, or accumulating hazardous dust.
Which heating systems require maintenance in the West Island?
All heating systems require maintenance. But each one has its own specific characteristics. Here’s what we see most often during our local service calls.
Gas or oil-fired furnaces (58 % of households still use them)
Natural gas and oil-fired furnaces are still the norm in the western part of the island. They’re reliable and powerful, but they require some attention.
The biggest risk? Carbon monoxide (CO). A cracked heat exchanger or a poorly adjusted burner can cause a CO leak. You can’t smell it or see it, but it’s deadly.
The Régie du bâtiment du Québec (RBQ) and the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ) require that gas systems be inspected by certified technicians. At Vortex Air, our technicians follow these standards to the letter.
Another important point: The Quebec government has announced a ban on repairs to oil-fired heating systems starting in 2025. If you still heat with oil, now is the time to plan your transition.
Warning signs (odors, noise, excessive consumption)
Does your furnace make a popping noise? Does it smell like something is burning? Has your gas bill doubled for no reason?
These are clear signs. Call a technician before it becomes an emergency. We once inspected a furnace in Dorval that was making a strange whistling noise. The problem? A crack in the heat exchanger. Thanks to early detection, the customer was able to avoid a complete replacement.
Boilers (hot water / steam)
Boilers are less common in single-family homes, but they are frequently found in apartment buildings and older properties in the West Island.
A poorly maintained boiler can develop pressure issues, leaks in the expansion tank, or scale buildup. Annual maintenance costs between 300 and 900 $, depending on the complexity of the system.
These costs may seem high, but a boiler breakdown in the middle of winter can easily cost you 2,000 $ in emergency repairs, not to mention water damage.
Heat Pumps (modern models rated for -30°C)
Heat pumps are gaining popularity in the West Island, and for good reason. They offer an energy efficiency ratio of 200 to 300 %, which means they produce 2 to 3 times more heat than the energy they consume.
But here’s what nobody tells you: a dirty heat pump loses up to 25 % of its efficiency. The filters get clogged, the coils collect dust, and the system has to work twice as hard to heat your home.
We recommend a complete maintenance check once a year, ideally before winter. For homes with a heat recovery ventilator (HRV) or energy recovery ventilator (ERV), maintenance should include these components as well.
Ducts and Central HVAC (dust + coastal humidity)
Ventilation ducts are your home’s circulatory system. They carry warm air throughout your home. But over time, they accumulate dust, allergens, and sometimes even mold.
In the western part of the island, the humidity from the lake accelerates this buildup. A thorough cleaning is recommended every 3 to 5 years. Some homes with pets or family members who have allergies should do this every 3 or 4 years.
After a thorough duct cleaning, there is often a 30 to 50 % reduction in airborne allergens. Want to breathe easier at home? Request a free duct inspection.
How often should maintenance be performed? (West Island-Specific Guide)
How often you should have your system serviced depends on your system, the age of your home, and your habits. Here are our recommendations based on our local experience.
Furnaces: Required once a year (proof required)
If you have a gas or oil furnace, annual maintenance isn't just recommended—it's often required to keep your warranty valid.
Manufacturers require proof of maintenance. If your furnace breaks down and you don't have a recent maintenance invoice, your warranty may be voided.
According to industry data, annual maintenance reduces the risk of breakdowns by 40 %. We see this in our own work: customers who have their furnaces serviced every fall almost never call for emergency service.
Heat Pumps: Pre-Winter Tune-Up + Mid-Season Micro-Check
For heat pumps, we recommend a thorough maintenance check before winter and a quick check-up around mid-season, especially if you also use it for air conditioning in the summer.
Modern heat pumps have sensors and predictive systems, but they’re no substitute for a human inspection. A trained technician can detect signs of wear and tear that your sensors won’t pick up.
Ducts: every 3–5 years
The general rule is every 5 years. But on the West Island, because of the humidity and the proximity to the lake, we tend to go with every 3 or 4 years.
If you have pets, young children, or family members with allergies or asthma, have it done every 3 years. It's really worth it.
Oil-fired heating systems: Must be serviced by the end of 2025
The Quebec government is banning major repairs to oil-fired heating systems starting in 2025. If you still heat with oil, now is the time to have your system thoroughly serviced and to plan your transition.
The good news? There are grants available. The Chauffez vert program offers up to 7,500 $ to replace an oil-fired system with a heat pump or an electric system. Want to know if you're eligible? Give us a call to discuss it.
How much will living expenses cost in the West Island in 2025?
Let's talk numbers. No hidden costs, no surprises. Here's what it really costs to maintain your heating system in our region.
Typical Prices (Residential vs. Light Commercial)
Here are the average prices observed in 2025:
- Gas furnace : between 200 and 400 $, depending on the size and condition of the system.
- Boiler : between 300 and 900 $. Older or more complex systems are more expensive to maintain.
- Heat pump : between 150 and 350 $. Maintenance is generally simpler, but you need to check both units (indoor and outdoor).
- Duct Cleaning : Between 400 and 800 $ for a standard single-family home. Larger homes or those with hard-to-reach ducts may cost more.
In the western part of the Island, add about 10 % for travel expenses if you’re farther away, such as in Senneville or Sainte-Anne-de-Bellevue. But at Vortex Air, we serve the entire region with no hidden fees.
Factors that influence costs (age of the house, access, type)
The cost depends on several factors:
- The age of your home. An old house with original ductwork takes longer to clean. Systems from the 1970s often require replacement parts.
- Accessibility. A furnace in a low-ceilinged, cramped basement in Dorval takes longer to maintain than a furnace in an open garage in Pointe-Claire.
- The type of system. An oil-fired furnace requires more maintenance than a modern heat pump. Steam boilers are more complex than hot-water boilers.
- General condition. If your system hasn't been serviced in 10 years, the first service will take longer and cost more. After that, annual services will be quicker.
ROI: Potential Savings from Annual Maintenance
Here's the interesting part: the interview saves you money.
A well-maintained system uses between 10 and 15 % less energy. For an annual bill of 1,500 $, that amounts to savings of 150 to 225 $. The cost of maintenance pays for itself within a year.
Avoiding breakdowns pays off even more. According to industry data, 80 % of heating system breakdowns could be prevented with regular maintenance. An emergency repair can easily cost between 500 and 1,200 $. An annual maintenance check? Between 200 and 400 $.
Do the math. It's not complicated.

What Is the Process for a Comprehensive Interview with Vortex Air?
When we come to your home, we do things the right way. No shortcuts, no rushing. Here’s our three-step process.
Step 1 — Free Inspection (Comprehensive Diagnostic)
We always start with a visual and technical inspection. We check:
Airflow (CFM) in your ducts. The condition of the filters (we check the MERV rating to see if they’re appropriate). Leaks in the ducts or seals. Carbon monoxide (CO) levels for your safety. The overall condition of your system: burner, motor, heat exchanger, expansion tank (if you have a boiler).
We take photos and write everything down. You see exactly what we see. No surprises.
Step 2 — Cleaning & Adjustments (depending on the type of system)
After the inspection, we move on to cleaning and making any necessary adjustments. Here's what we do, depending on your system:
- Gas furnace : cleaning the burner, checking the heat exchanger, adjusting the gas pressure, inspecting the fan.
- Boiler : Checking the expansion tank, adjusting the water pressure, cleaning the burners, and inspecting the valves and gaskets.
- Heat pump : cleaning the indoor and outdoor coils, checking the refrigerant level, inspecting the electrical connections.
- Ducts : thorough cleaning using specialized equipment, disinfection if necessary, and sealing of leaks.
We use professional-grade tools and follow industry protocols. Our technicians are INVC-certified, and we are in the process of obtaining NADCA certification, which means we meet the highest industry standards.
Step 3 — Final Test + Report (Before/After)
Once the work is complete, we conduct a thorough test to ensure that everything is working perfectly. We measure the airflow again, verify the system’s efficiency, and provide you with a detailed report that includes before-and-after photos.
You know exactly what we've done and why. If we see any potential issues in the coming months, we'll be honest with you about them. No hard selling. Just recommendations based on our experience.

Challenges and Regulations Specific to the West End of the Island
Living on the West End of the Island is wonderful. But it comes with its own set of challenges for your heating system. Here’s what you need to know.
RBQ Regulations for Gas and Combustion Systems
In Quebec, all work on gas heating systems must be performed by contractors with a valid RBQ license. It’s not just a formality—it’s for your safety.
An uncertified technician may fail to detect a gas leak or a problem with the exhaust system. Fines for non-compliant work can reach 1,000 $ for the homeowner and much more for the contractor.
When you call Vortex Air, you can be sure that our technicians comply with all RBQ and CMMTQ standards. We take this seriously because your safety depends on our work.
Available Grants (Heat Green 2025–2026)
If you’re still heating with oil, there’s good news. The government’s “Chauffez vert” program offers grants of up to 7,500 $ to replace your system with a heat pump or an electric system.
This is a significant grant that can cover a large portion of your conversion costs. Applications are processed quickly, but there are eligibility requirements that must be met.
We can help you navigate the process. We know the requirements, we know which systems are eligible, and we can even refer you to certified installers if necessary.
Insulation & Common Heat Loss Along Lake Shores
Homes on the lake—in Beaconsfield, Pointe-Claire, or Baie-D’Urfé—are beautiful. But they suffer significant heat loss due to wind and humidity.
Partially underground basements, poorly insulated walls, and old windows create thermal bridges. Your heating system has to compensate for these heat losses, which increases your energy consumption and accelerates wear and tear.
If you notice that certain rooms are always cold or that your bills are going up for no apparent reason, the problem might not be your heating system—it could be your insulation. We can assess this during our free inspection and give you honest recommendations.

FAQ – Heating Maintenance in the Western Part of the Island
Here are the questions we’re asked most often. If your question isn’t on the list, give us a call. We’ll be happy to answer it.
How much does it cost to maintain a gas furnace in Pointe-Claire?
Between 200 and 400 $, depending on the size and condition of your furnace. If it hasn't been serviced in a long time, the first service may take longer and cost a little more. But after that, annual services are quicker.
What is the recommended frequency for cleaning vents in the West Island?
We recommend getting tested every 3 to 4 years, due to the humidity at the lake and the local air quality. If you have pets or family members with allergies, get tested every 3 years.
Do heat pumps really work at -30 °C in Montreal?
Yes, modern models operate efficiently down to -30 °C with an efficiency of 200 to 300 %. However, they must be properly maintained to maintain this performance. A dirty filter or clogged coils can reduce efficiency by 25 %.
How can I tell if my furnace is wasting energy?
If your energy bill has gone up for no apparent reason, if some rooms are cold while others are too hot, or if your furnace is making unusual noises, it’s probably not running efficiently. A service call can fix that.
What signs indicate a risk of CO emissions?
Carbon monoxide is invisible and odorless. But here are some indirect signs: frequent headaches in the winter, nausea, unexplained fatigue, or soot stains near your furnace. If you have any doubts, have your system inspected immediately and install CO detectors in your home.
Is the annual maintenance required for the warranty?
Yes, for most manufacturers. If your furnace or heat pump breaks down and you don't have proof of regular maintenance, your warranty may be voided. Always keep your maintenance receipts.
How does the “Chauffez vert” grant work for replacing heating oil?
The program offers up to 7,500 $ to replace an oil-fired system with a heat pump or an electric system. You must own a primary residence in Quebec, and the system must be installed by a certified contractor. We can help you navigate the process.
Why are services sometimes more expensive on the West Island?
Mainly because of travel costs. The West Island is farther from downtown Montreal, so some companies add about 10 % for transportation. At Vortex Air, we serve the entire region with transparent rates—no surprises on your bill.
Protect Your Home This Winter
Winter in Quebec is no joke. Your heating system will run for thousands of hours between November and March. It will circulate warm air throughout every room, protect your pipes from freezing, and keep your family comfortable.
