It’s a Tuesday morning in February. You wake up and it’s 3°C outside after a week of -15°C. You think this is good news—winter is easing up a bit. But in reality, it’s exactly this kind of day that can cause serious problems for your heating system.
Freeze-thaw cycles in Montreal are changing. Twenty years ago, we typically had 3 to 5 per winter. Today, according to projections from Climate Atlas Canada, we could see 6 to 8 in the coming years. And these cycles aren’t just a nuisance for your car or your boots—they directly affect your home and your heating system.
Winters are becoming more unpredictable. The winter of 2025 is a good example: periods of intense cold followed by unexpected warm spells that push temperatures above zero for a few days. This puts enormous strain on Montreal homes, especially older buildings that weren’t designed to handle such extreme fluctuations.
If you live in a house built before 1980 in neighborhoods such as Rosemont, Montréal-Nord, or Ahuntsic, this is especially relevant to you. These homes have heating systems and insulation that date back to a time when winters were more stable and predictable.
Understanding Freeze-Thaw Cycles in Montreal
To protect your home and your heating system, you first need to understand what really happens during a freeze-thaw cycle. It’s not just «it’s hot, then it’s cold.» It’s much more complex than that.
What Is a Freeze-Thaw Cycle (Quebec Version)?
A freeze-thaw cycle occurs when the temperature rises above 0°C long enough to melt the snow and ice, then drops back below 0°C and freezes again. This can happen over several days, or even in just a few hours if there are significant day-night temperature fluctuations.
In Montreal, these cycles are particularly intense. You might have a sunny day when the temperature rises to 5°C in the afternoon, causing the snow to melt and leaving water everywhere. Then, at night, the temperature drops to -10°C and all that water freezes.
When water freezes, it expands, taking up about 9 % more volume. That’s enough to create enormous pressure in cracks, pipes, and building materials. This is called the formation of «ice lenses.» Water seeps into small openings during the thaw, and then when it freezes, it widens those openings. Cycle after cycle, the damage accumulates.
It’s different from what happens in Europe, for example. A typical French winter has fewer extreme fluctuations. In Montreal, temperatures can swing from -20°C to +5°C in just a few days, then drop back down to -15°C. These sudden swings are characteristic of our continental climate.
The materials in your home—concrete, pipes, joints, shingles—are not designed to withstand these repeated stresses. Each cycle weakens them a little more.
Recent Climate Data for Montreal
The numbers speak for themselves: our winter climate is changing. According to data from Ouranos, the Quebec-based organization that studies climate change, the frequency of freeze-thaw cycles has increased by about 15 % during the winter months since the 2000s.
It may seem contradictory, but here’s what’s happening: the total number of days with freezing temperatures each year is decreasing (winters are generally shorter), but freeze-thaw cycles during the winter are becoming more frequent and more intense. We’re seeing fewer periods of stable cold weather and more fluctuations.
Climate models based on the RCP8.5 scenario—the high-emissions scenario—suggest that this trend will continue. By 2050, Montreal winters could become even more variable, which means greater stress on buildings and heating systems.
The winter of 2024–2025 was a perfect example. We had temperatures below -20°C in January, followed by a warm spell with temperatures reaching 7°C a few days later, and then a sudden return to cold weather. These rapid fluctuations are exactly what cause the most problems.
Data from Meteorological Service of Canada also show that winter precipitation patterns are changing. We’re seeing more freezing rain and rain on snow, which adds water to the system at the most critical time.
Why Freeze-Thaw Cycles Directly Affect Your Heating System
You may think that your heating system is inside the house and therefore protected. But freeze-thaw cycles still affect your heating system in several direct and costly ways.
Frozen Pipes and Preventive Overheating
The most well-known risk is frozen pipes. But what many homeowners don’t realize is that mild winters with freeze-thaw cycles increase this risk by 30 to 50 % compared to a consistently cold winter.
Why? Because during thaws, homeowners naturally turn down their heat. It’s 5°C outside, the sun is shining, and the house warms up on its own. You turn down the thermostat to save money. Then at night, the temperature drops sharply to -12°C, and certain sections of piping—especially those in exterior walls, crawl spaces, or near windows—drop below freezing.
Homes in Montreal that are more than 50 years old are particularly vulnerable. In neighborhoods such as Montreal North, Ahuntsic, and Saint-Laurent, many homes were built with minimal insulation and pipes running through unheated areas. At the time, these temperature fluctuations were not anticipated.
When a pipe freezes and bursts, repair costs can be significant. Typically, it costs between 500 $ and 2,000 $ to repair the pipe, not counting water damage, which can easily triple that bill if the pipe bursts while you’re away from home.
The natural reaction of many homeowners is to overheat their homes «as a precaution» during periods of unstable weather. You turn the thermostat up to 22–23°C instead of 20°C, just to make sure the pipes don’t freeze. It works to prevent freezing, but it unnecessarily increases your energy consumption.
Impact on Energy Consumption
Freeze-thaw cycles create a frustrating dance with your heating system. Your thermostat tries to maintain a stable temperature, but the outdoor conditions are constantly changing.
During a warm spell, your home heats up quickly—sometimes too quickly. The heating system shuts off. Then, when the cold returns, your system has to work hard to make up for the lost heat. This type of stop-and-start operation is less efficient than constant, steady heating.
Studies on residential energy consumption show that about 10 to 15 % more energy is used to maintain a comfortable temperature during periods of frequent freeze-thaw cycles, compared to a winter with stable temperatures. For an average Montreal home that pays 150 $ to 200 $ per month for electric heating in the winter, this represents an additional 15 $ to 30 $ per month.
But there’s another interesting effect: during milder winters with fewer days of extreme cold, your total heating bill can drop by 150 $ to 200 $ for the season. That’s a real savings. The problem is that these savings come with increased risks to your heating system and plumbing.
There’s also what’s known as the «rebound effect.» After a warm spell when you’ve turned down the heat, the return of cold weather forces your system to run at full capacity for hours to warm up the house. This is when electric baseboard heaters, heat pumps, and furnaces work the hardest, and that's also when breakdowns are most frequent.
If your heating system hasn't been serviced recently, these periods of high demand can reveal hidden problems. A clogged filter, a dirty fan, or blocked ducts will reduce efficiency exactly when you need it most.
Heat Pumps and Modern Systems: Not Immune to Freeze-Thaw Cycles
Many homeowners believe that because they have a modern heating system, such as a heat pump, they are immune to freeze-thaw problems. This is a costly misconception.
How a Heat Pump Can Freeze
Heat pumps are excellent for Quebec's climate. Newer models operate efficiently even at -25°C or -30°C. But they have one drawback: frost builds up on the outdoor unit when they operate in cold, damp weather.
This is normal and expected. Heat pumps have an automatic defrost cycle that temporarily reverses the operation to melt accumulated frost. It works well under stable winter conditions.
But during freeze-thaw cycles, things get complicated. The humidity in the air increases significantly during thaw periods. When the temperature drops rapidly, this moisture freezes on the coils of the outdoor unit. If the automatic defrost system is clogged with dust or debris, or if it malfunctions due to a lack of maintenance, frost builds up.
We have seen outdoor units completely trapped in a block of ice after a few intense freeze-thaw cycles. At this point, the heat pump can no longer operate efficiently. Efficiency can drop by 20 to 40 %, depending on the extent of the ice buildup.
Multi-zone (mini-split) heat pumps are particularly vulnerable because they often have several indoor wall-mounted units connected to a single outdoor unit. If the outdoor unit freezes, all the rooms it serves lose heat at the same time.
We see these problems frequently in Laval, on the South Shore, and in the West Island, where many homes have had heat pumps installed over the past 10 years. Homeowners call us because their system is making strange noises, blowing cold air instead of warm air, or shutting down completely.
In most cases, the problem stems from a lack of maintenance. The filters in wall-mounted units are clogged, the outdoor coils are dirty, or the condensate drain is blocked. When a severe freeze-thaw cycle occurs, the system cannot handle the additional workload.
Preventive Maintenance vs. Costly Repairs
The cost difference between preventive maintenance and emergency repairs is striking.
Professional Cleaning wall-mounted unit typically costs between 80 $ and 150 $ per unit. If you have three units in your home, you’ll spend 240 $ to 450 $ for a complete maintenance service. This is recommended once a year, ideally in the fall before winter begins.
By comparison, an emergency repair in the middle of winter can easily cost 300 $ to 800 $ just for the service call and diagnosis, not including parts and labor. If your heat pump’s compressor fails due to overload, you could face a bill of 1,500 $ to 3,000 $.
Preventive maintenance includes cleaning the filters and the indoor and outdoor coils, checking the defrost system, inspecting the electrical connections, and performing a performance test. It takes about 45 minutes to an hour per unit.
Have your system inspected before the next thaw to ensure it is ready to handle temperature fluctuations. A well-maintained heat pump will not only prevent breakdowns but also operate 15 to 25 % more efficiently, reducing your heating costs.
At Vortex Air, we clean hundreds of wall-mounted units every year in Montreal and the surrounding area. We regularly come across units that haven’t been cleaned since they were installed 5 or 7 years ago. The filters are so clogged that we wonder how any air can still get through. The coils are covered with a layer of dust and grease. Under these conditions, the system has to work twice as hard to heat the same area.
Cleaning the ventilation ducts also plays a role. If your ducts are clogged, air doesn't circulate properly throughout the house. Some rooms stay cold while others get too hot. Your heating system compensates by running longer, which increases costs and wear and tear.
Facts vs. Myths About Freeze-Thaw Cycles and Heating
There are many ideas floating around in conversations among neighbors or on online forums. Some are useful; others could end up costing you a lot of money. Let’s separate fact from fiction.
Common Myths in Montreal (and Why They're Wrong)
Myth #1: If I turn down my heat on mild days, I’ll save a lot of money
This is partly true in terms of savings, but it comes with risks. Turning down the heat by 2–3°C on a mild day can indeed reduce your energy consumption. But if you turn it down too much (below 16–17°C) or turn off the heat completely, you risk freezing your pipes when the temperature drops again at night.
The key is to lower the temperature moderately—from 20°C to 18°C, for example—but never below 16°C if you have pipes in uninsulated areas. The actual savings from a 2–3°C reduction are about 5 to 8 % on your heating bill, which is significant without being risky.
Myth #2: Milder winters mean there’s no risk of frozen pipes
It’s exactly the opposite. Mild winters with freeze-thaw cycles increase the risk because homeowners let their guard down. You think, «It’s almost zero—that’s fine,» and you turn down the heat or neglect certain precautions. Then comes a night when the temperature drops to -12°C, and the poorly protected pipes freeze.
Cold, stable winters are actually safer for plumbing because you maintain a constant temperature. It's the fluctuations that cause problems.
Myth #3: If my pipes freeze, I can thaw them with a blowtorch or a torch
NEVER do this. Applying an open flame to pipes can cause fires, cause pipes to burst due to steam pressure, or damage seals and fittings. If you suspect that a pipe is frozen, turn off the water at the main valve and call a plumber.
If you want to try thawing the pipe yourself while waiting for the plumber, use a hair dryer or warm towels, and start near the faucet, working toward the frozen section. Open the faucet slightly to allow water to flow out as the ice melts.
Myth #4: Modern heat pumps don't need maintenance because they're «high-tech»
Modern heat pumps are indeed more technologically advanced, but they still accumulate dust, dirt, and debris. Filters get clogged, coils become fouled, and the condensate drain can become blocked. Without annual maintenance, even the best system will lose efficiency and be at risk of breaking down.
It's like a new car—it has the latest technology, but it still needs oil changes and regular maintenance.
Best practices validated by experts
Now, here's what really works, based on real-world experience and recommendations from construction experts.
Use «frost protection» mode or maintain a temperature of at least 8–10°C
If you’re away from home for a few days during the winter, never turn the heat down below 10°C, and ideally keep it at 12–15°C. The few dollars you «save» by turning it down further aren’t worth the risk of coming home to burst pipes and thousands of dollars in water damage.
Many modern thermostats have a «vacation» or «frost-protection» setting that automatically maintains a safe temperature. Use it.
Make sure the automatic defrost feature on your heat pump is working
You should hear your heat pump go through a defrost cycle from time to time; the outdoor unit makes a different noise, and sometimes steam comes out. If you’ve never noticed this, or if you see a lot of ice buildup on the outdoor unit, have the system inspected. The automatic defrost system may be malfunctioning.
Have an energy audit performed for homes built before 1980
If your home is more than 40 years old and has never been updated in terms of insulation and weatherization, a professional energy audit can identify where you’re losing heat. This helps you prioritize the improvements that will really make a difference.
The City of Montreal and Hydro-Québec sometimes offer grant programs or discounted energy audits. This is a good way to learn more about your home without spending a fortune.
Clean your ventilation ducts and wall-mounted units once a year
This improves air circulation, reduces the strain on your heating system, and removes allergens and dust that build up. A well-ventilated home is also one where heat is distributed more evenly, which reduces cold spots where pipes could freeze.
Insulate exposed pipes
If you have pipes running through the crawl space, the garage, or near exterior walls, insulate them with pipe insulation foam. It costs just a few dollars at the home improvement store and can prevent freezing. It’s an easy weekend project.
The Reality in Montreal: Neighborhoods and Buildings at Greater Risk
Not all homes in Montreal are equally resilient to freeze-thaw cycles. Certain neighborhoods and certain types of buildings are much more vulnerable than others.
Old Buildings and Inadequate Insulation
Homes built before 1980 make up a large portion of Montreal’s housing stock. In neighborhoods such as Rosemont, Montreal North, Saint-Laurent, Villeray, and Ahuntsic, you’ll find thousands of homes dating from the 1950s, 1960s, and 1970s.
These homes were built to insulation standards that are very different from today’s. Back then, people talked about R-12 or R-20 in the walls, and sometimes just R-12 in the attic. Today, the recommendation is R-24 in the walls and R-50 in the attic. The difference is enormous.
Inadequate insulation means that these homes lose a lot of heat. Heating systems have to work harder. And during freeze-thaw cycles, indoor temperature fluctuations are more extreme, which puts more strain on the entire system.
Many of these homes also have plumbing systems that date back to when they were built. Aging galvanized steel or copper pipes become more brittle. Seals can develop microscopic cracks over the years. When a freeze-thaw cycle occurs, these weak spots can fail.
If you live in one of these homes, you’re not doomed to have problems. But you need to be more vigilant. Check high-risk areas regularly. Consider targeted improvements such as insulating pipes, sealing air leaks, and improving attic insulation.
Typical Montreal duplexes and triplexes, with their outdoor spiral staircases and shared walls, present their own challenges. The exterior walls are often poorly insulated. The spaces under the stairs can get very cold. The pipes that supply the upstairs units sometimes run through unheated areas.
New Standards and Assistance for 2025
The good news is that there's help available to improve your home.
The City of Montreal's Climate Plan includes initiatives to help homeowners adapt their buildings to changing climate conditions. This includes grants for insulation, replacing energy-inefficient heating systems, and improving energy efficiency.
Hydro-Québec also offers several programs, including the Hilo program, which aims to reduce peak electricity demand on very cold days. You can receive financial rewards by agreeing to lower your heating slightly during peak periods (typically a few hours in the morning and evening).
But be careful: if you participate in Hilo, make sure you understand the implications. Turning down the heat during peak hours may be fine if your home is well-insulated. But if your insulation is inadequate, you could create cold spots that put your pipes at risk. Use this program wisely, not blindly.
Transition énergétique Québec also offers programs for homeowners who want to install heat pumps, improve insulation, or make other energy-efficient renovations. Grants can cover a significant portion of the costs.
Find out about these programs before you start any work. You could save hundreds or thousands of dollars on improvements you were going to make anyway.
How to Protect Your Heating System from Freezing and Thawing
Enough with the theory. Here's exactly what you can do to protect your heating system and avoid problems this winter.
Freeze-Thaw Checklist (Homeowners)
Maintain a minimum safe temperature
Set your thermostat to at least 16–17°C, even when you’re not home. If you’ll be away for more than 48 hours, keep it at 15°C or lower. It’s a small heating expense that can save you thousands of dollars in repairs.
For homes with particularly vulnerable areas (unfinished basements, crawl spaces), consider installing separate thermostats or supplemental heaters for these spaces.
Clean Your Wall-Mounted Units Before Winter
If you have heat pumps or wall-mounted units, clean them in the fall. Remove the filters and wash them (or replace them if they aren’t washable). Vacuum the visible coils. If you’re not comfortable doing this yourself, call a professional.
A professional cleaning goes a step further: we disassemble the units, thoroughly clean the coils with specialized products, check the condensate drain, and test the system. This ensures that your heat pump will operate at peak efficiency all winter long.
Check your ventilation ducts
If you have a central heating system with ducts, make sure all the dampers are open and that air is circulating properly throughout all the rooms. Clogged or improperly balanced ducts can create cold spots in certain parts of the house.
If you can't remember the last time your ducts were cleaned, it's probably time. Clogged ducts reduce your system's efficiency by 20 to 30 %, depending on the extent of the buildup.
Inspect the air exchanger
If you have a air exchanger (VRC or VRE), clean the filters and make sure the drains aren't frozen. A properly functioning air exchanger improves air quality and helps control humidity, which indirectly reduces the risk of frozen pipes.
Insulate exposed pipes
Check your basement, crawl space, and garage. Identify all pipes that are exposed to the cold. Wrap them with pipe insulation (available at any home improvement store for a few dollars per meter).
Pay special attention to pipes near exterior walls, basement windows, garage doors, and ventilation vents.
Let a trickle of water run on very cold nights
If the temperature is expected to drop below -15°C and you have pipes in areas at risk, let a small trickle of water (about the size of a pencil) run from the faucets connected to those pipes. Moving water freezes much less easily than standing water.
Open the cabinet doors under the sinks
Kitchen sinks and bathroom Pipes located on exterior walls are vulnerable. On cold nights, open cabinet doors to allow warm air from inside the house to circulate around the pipes.
Clear the snow around the outdoor unit of your heat pump
Keep at least 30–50 cm of clear space around your heat pump’s outdoor unit. Remove any snow that accumulates against it after storms. Make sure the unit is slightly elevated to prevent it from becoming trapped in a snowdrift.
When to call in a professional
There are certain signs that indicate it's time to call an expert rather than trying to fix things yourself.
Odors unusual noises coming from your heating systems
If you smell something burning, musty, or like gas, turn off the system and call someone immediately. A burning smell may indicate an electrical problem or an overheated motor. A musty smell suggests mold in the ducts. A gas smell requires emergency attention.
Excessive humidity or condensation
If you notice a lot of condensation on your windows, moisture running down the walls, or signs of mold, you probably have a ventilation problem. A house that’s too humid during the winter can cause water to freeze inside the walls and lead to structural damage. A professional can identify the source of the problem and suggest solutions.
Frost on the outdoor unit that won't melt
A little frost on your heat pump is normal. But if the unit is completely covered in ice, if the frost doesn't melt, or if the system shuts down frequently, there's a problem with the defrost cycle or with air circulation. This requires a professional inspection.
Unusual Noises
Clattering, squeaking, whistling, or sounds of a struggling engine are never normal. These can indicate worn parts, blockages, or mechanical problems that will get worse if you wait.
Heating bills that skyrocket for no reason
If your energy consumption increases by 30–40 % or more without any obvious change in your usage, your system may be operating in degraded mode. A professional diagnostic can identify why the system is working so hard and correct the problem before it leads to a costly breakdown.
Request an on-site assessment if you notice any of these signs. At Vortex Air, we offer free inspections that give you a clear picture of your system’s condition. We’ll explain what’s working well, what needs attention, and what your options are. No pressure—just honest information so you can make the best decision for your home.

FAQ, De-icing and Heating in Montreal
What is the lowest temperature I should keep my house at if I'm going on a trip during the winter?
Keep your thermostat set to at least 15°C, ideally 16–17°C if your home is older or poorly insulated. Never set it below 12°C. The few dollars you save on heating aren’t worth the risk of coming home to burst pipes and thousands of dollars in damage. If your thermostat has a «vacation» or «frost-protect» mode, use it—it will automatically maintain a safe temperature.
Does my heat pump operate efficiently during a mild winter with frequent freeze-thaw cycles?
Yes, modern heat pumps are designed to handle temperature fluctuations. But they must be properly maintained. During freeze-thaw cycles, frost buildup can be more significant due to high humidity. If your system hasn’t been cleaned recently, the automatic defrost cycle may not work as well as it should. Have your wall-mounted units cleaned and the outdoor unit inspected annually to ensure maximum performance.
Are the pipes in my condo at risk of freezing, or is that just a problem for houses?
Condos can also have problems, especially if your unit is located near an exterior wall or on the top floor. Pipes that run through exterior walls or unheated spaces can freeze. Condos in modern high-rises are generally better protected, but condos in converted or older buildings may be vulnerable. If you live in a condo, check with your homeowners’ association to see what preventive measures are in place and whether you have any individual responsibilities.
I've noticed a lot of condensation on my windows after a thaw. Is this normal?
A little condensation is normal when the outside temperature changes rapidly. But if you see a lot of water running down the windows or completely fogged-up windows, it’s a sign that the relative humidity in your home is too high. This may indicate a ventilation problem. Make sure your air exchanger is working properly, use bathroom fans when you shower, and avoid drying laundry indoors. If the problem persists, have your ventilation system inspected.
Does Hydro-Québec's Hilo mode increase my risk of frozen pipes?
It depends on your home. The Hilo program asks you to slightly lower your heating during peak electricity hours (typically a few hours a day). If your home is well-insulated and your pipes are protected, this temporary reduction shouldn’t be a problem. But if your insulation is inadequate or if you have pipes in vulnerable areas, turning down the heat could create dangerous cold spots. Use Hilo wisely—do not participate in events on nights when the temperature is expected to drop below -15°C if your home is at risk.
Do I really need to have my heating and ventilation system cleaned every year?
For heat pumps and wall-mounted units, yes, annual cleaning is strongly recommended. For ventilation ducts, it depends. If you’ve never had your ducts cleaned and your home is more than 10 years old, have them cleaned at least once. After that, every 3 to 5 years is usually sufficient, unless you have pets, allergies, or have done renovations that created a lot of dust. A clean system works better, lasts longer, and saves you money on your heating bills.
What are the signs that a pipe is freezing before it bursts?
Early signs include: a very weak trickle of water when you turn on a faucet (while other faucets are working normally), unusual noises in the pipes when you turn on the water, or visible frost on an exposed pipe. If you notice any of these signs, take action immediately. Open the faucet slightly to allow the water to flow, turn up the heat in the affected area, and try gently warming the pipe with a hair dryer. If the problem persists, call a plumber.
Who should I call for preventive care rather than in an emergency?
For preventive maintenance of your heating and ventilation systems, call a company that specializes in air quality and ventilation, such as Vortex Air. They can inspect your system, clean your wall-mounted units and ducts, and identify potential problems before they become emergencies. For insulation and air sealing in your home, an energy efficiency consultant can conduct an audit. For plumbing, a plumber can inspect your pipes and insulate high-risk areas. Investing in prevention is always less expensive than emergency repairs.
Freeze-thaw cycles in Montreal are a reality that will continue and likely intensify in the coming years. But with the right knowledge and preventive measures, you can protect your home, your heating system, and your wallet.
Don't let an unpredictable winter catch you off guard. Take the time now to check your system, make any necessary adjustments, and get ready for the cold months ahead.
