Winter in Ontario can hit hard. Whether it is a cold snap or a long stretch of snow and ice, the temperatures in towns like London drop fast and stay low. That kind of weather means home heating systems are working nonstop to keep people warm. When something stops working, someone has to fix it fast.

That is where HVAC technicians come in. They are the people who keep furnaces running, heaters safe, and homes comfortable. If you are thinking about getting into skilled trades, this kind of work can be a great fit. Our HVAC programs in London give students the tools and hands-on training they need to work on systems in homes and workplaces. It is not just about solving technical problems. It is about helping real people stay safe and warm when it matters most.

For anyone who is more of a hands-on learner or looking for a job where no two days feel the same, HVAC might be the right move.

Understanding the Role of HVAC in Cold Weather

HVAC stands for heating, ventilation, and air conditioning. In the winter, heating and airflow are the big focus. A working HVAC system moves warm air through a home or building and makes sure air is clean and safe.

When systems break down, it often happens during colder periods when systems are under the most strain.. Some common issues include:

• Heaters that blow cold air

• Blower motors that stop working altogether

• Frozen pipes or coils that prevent heat from moving properly

When that happens, people do not just feel uncomfortable. They can be at risk, especially kids or older adults. That is why trained HVAC technicians are in demand in the colder months. They have the skills to figure out what is wrong, fix the problem quickly, and get things up and running again.

What Students Learn in HVAC Programs

In hands-on training, students do not just learn from a textbook. They take apart real systems, test furnace parts, and work with actual tools. The job has a lot of moving pieces, so learning by doing helps everything make more sense.

Some core skills students practise include:

• Checking heat exchangers to make sure they are working safely

• Measuring airflow and finding blockages

• Fixing or replacing broken thermostats and burners

In our HVAC Technician program on the London campus, students get time in a workshop where they can work on equipment in conditions that feel close to the real world. That way, when they graduate, they already know what it is like to work with heating systems in a Canadian winter. You can learn more about our hands-on HVAC training here: https://nats.ca/programs/hvac-technician/

The program includes in-depth coverage of residential and light commercial systems, code compliance, and system troubleshooting in cold climates. North American Trade Schools provides access to modern HVAC labs, expert instructors with trade experience, and dedicated job search support for students in London.

Safety and Troubleshooting in Tough Conditions

Working in cold weather brings added pressure. A small mistake can lead to a big issue, so safety skills are part of everything students learn. That includes how to avoid electrical shock, deal with gas leaks, and use proper protective gear when working on rooftops or in snow-covered corners of a house.

Troubleshooting is another big piece of the puzzle. Students are trained to spot common signs of system failure and run checks to find the root cause. That could mean tracing wires, testing sensors, or climbing into tight attic spaces during cold weather calls.

Techs often respond to emergency calls during freezing conditions. Getting comfortable with fast-paced problem-solving in tough workplaces is part of becoming job-ready. Students also learn to keep calm and focused in stressful situations, which is important for working safely and making the right repair choices. Adaptability and a clear head are key traits for HVAC techs, and these are built up through both classroom learning and practical scenarios in the shop lab.

Local Career Readiness in London, Ontario

One of the benefits of learning in London is that you start building experience in the kind of climate and settings you will be working in later. There is no guessing about what future winters will be like, because you are trained right where you will likely be working.

The growing number of homes, townhomes, and businesses across London means more heating systems and more service calls when those systems break. By training locally, students get familiar with the types of systems common in the area, the challenges of older buildings, and the best ways to reach job sites when heavy snow hits.

It is one thing to learn the tools. It is another to know how to apply them in the real streets and neighborhoods where people live. Employers appreciate it when new workers understand the local area and what it takes to get from one site to the next. Students will also get a sense of the different types of customers they might help, from families in older homes to owners of small shops.

Some HVAC grads find their first jobs through local connections made during training or work placements. Others use their knowledge of London’s neighbourhoods to seek out employment in areas with the most need, like expanding suburbs or established communities with aging heating systems. Knowing the area you work in can make you a stronger candidate for local positions and help you provide better service.

Real Skills That Lead to Real Opportunities

The biggest takeaway from HVAC training is that it is skill-building, not just studying. From day one, students are taught how to fix, install, and maintain actual systems. Those skills turn into real jobs, often as apprentices or entry-level techs.

Every winter, there is a strong need for workers who can keep heat running and people safe. Employers are looking for workers who are trained and ready to show up, even when the weather gets rough. Students coming out of HVAC programs in London are starting with a strong base and a sense of what work in this industry really looks like. That confidence matters on the coldest days.

HVAC work changes with the seasons, but winter always brings urgent needs. Many graduates quickly find jobs as service techs, installers, or maintenance helpers. The work is steady, and every new call is a chance to learn and grow. Apprenticeship is a big part of getting into the field after school, and most grads continue learning on the job after they leave the classroom.

The winter season may be tough, but it is also the time when skilled HVAC technicians are needed most. When you are trained to handle those calls, you are never far from the next opportunity.

If you’re thinking about a hands-on career, looking into HVAC training in Ontario might bring up a few questions. Maybe someone told you it takes years to finish, or that you need to be skilled in tools before you even start. It’s easy to see how these ideas can feel discouraging, especially if you’re new to the trades.

We talk to a lot of future students from London who are curious but unsure about stepping into HVAC training. The truth is, many of these concerns are based on common myths. Let’s walk through a few of them so you can get a better picture of what this career path really looks like and why it might be a great fit.

You Need to Have Experience Before You Start

This is one of the things we hear most. People worry that if they haven’t worked with tools before or don’t have a background in trades, they won’t be ready to start HVAC training. The good news is, that’s not true.

• HVAC programs are built for beginners. We don’t expect students to come in already knowing how systems work. The goal is to teach you from the ground up.
• Training focuses on hands-on learning. That means you won’t be stuck reading textbooks alone, you’ll be using real tools, working through real setups, and getting support as you build skills each day.
• Instructors guide you as you go. Whether it’s learning how to troubleshoot a furnace or practicing how to handle refrigerants, this is something you’ll learn by doing, not something you need to know ahead of time.

For anyone without trade experience, it’s more than possible to succeed. If you’re ready to learn and want to work with your hands, that’s a solid place to start. Even if you have never stepped into a workshop, these programs start at the basics and help newcomers get comfortable at every stage. Your instructors know how to break skills into steps and teach you so that you feel ready, not overwhelmed.

HVAC Training Takes Years to Complete

Another big worry is time. Some people picture HVAC training as a long, drawn-out process, one that could take years before you’re even close to being job-ready. That’s not usually the case.

• Focused HVAC courses can be completed in less time than you might think. With a clear training schedule and practical instruction, you’re able to move through topics at a steady pace.
• You’ll learn both theory and tools as part of your routine. One day you might study how systems work, the next, you could be hands-on with ductwork or electrical components.
• The goal is to help you move from student to technician in a way that feels doable and measured.

Most people learning HVAC are also balancing life, family, or even part-time jobs. With the right training structure, it’s possible to stay on track and start moving toward a career without waiting years to see progress. The HVAC Technician Diploma Program at North American Trade Schools in London is designed to be completed in less than a year, making it accessible for those looking for a direct path into the trades. By focusing on what matters most, these courses keep learning efficient without feeling rushed. You get the skills you need in a shorter time, so you can build experience and start working sooner.

The Work Is All Technical and Not for Everyone

Some people picture HVAC techs working with complicated machines all day, and that image can feel intimidating. While it does include technical tasks, HVAC work is about more than just tools and parts.

• Yes, there’s equipment to work with, but there’s variety too. You might be checking safety standards, talking with clients, or doing preventive maintenance.
• Technicians often need soft skills along with technical ones. That includes showing up on time, communicating clearly, and working respectfully in homes or businesses.
• In training, you’ll learn both sides. You’ll gain comfort using equipment while also building good habits around safety, customer service, and troubleshooting.

The truth is, many HVAC tasks become less scary once broken into steps. Whether you’re working with tools or making system checks, it’s a skill you’ll build gradually, not something you need to have figured out from day one. As you spend more time in class and in the shop, you find that your confidence grows and the work starts to feel familiar. That mix of hands-on practice and soft skill building helps you get ready for the job, not just the tasks. Instructors help students solve problems one step at a time, so you never feel like you’re on your own or expected to know it all without help.

There Aren’t Many Jobs If You Stay Local

We hear this often from people in London, they wonder if they’ll need to move to find work after training. HVAC might seem like a niche field, but it’s actually deeply rooted in daily life.

• HVAC systems are everywhere. Homes, schools, stores, offices, all of them depend on heating and cooling that works year-round.
• When something breaks or needs maintenance, someone local needs to step in. Technicians who can respond quickly are especially valuable in colder seasons.
• Local HVAC training connects you with local job needs. You’ll learn based on the tools and systems used here in Ontario, which makes your training more relevant and job-ready.

The demand for skilled trades isn’t limited to big cities. Communities across Ontario rely on HVAC techs, and being trained in London gives you a strong start right where you are. North American Trade Schools also offers job search assistance to help graduates connect with local employers in the London area. Students are matched with employers who need local techs, helping you find a fit that works for your life and your skills. Because this work is so central to everyday comfort, there’s always a place for someone who’s trained, dependable, and eager to begin their career in their own community.

It’s Just Tools and Tech, Not a Real Career Path

Another idea we hear goes like this: “Is this really a long-term career, or just a short-term fix?” HVAC might seem like a trade that gets you by, but it actually offers a lot of room to grow.

• HVAC techs can work in different places, home service, building systems, commercial spaces, and more.
• With experience, technicians can move into roles like lead installer, service manager, or even start their own business.
• The training you get lays the foundation for a durable skill set, one that machines and AI can’t replace.

This isn’t just a job that fills a gap. It’s a skill-based path where the work you do matters, the tools mean something, and your growth depends on how much you want to take on. Many graduates find that the variety keeps things interesting, with opportunities to take on new challenges as they build experience. Over time, what starts as an entry-level job can become a stepping stone to roles that offer more responsibility, leadership, or special training. If you’re looking for stability and room to advance, HVAC gives you options that last.

Setting the Facts Straight and Moving Forward

Believing in common misconceptions can hold you back from a great opportunity. At North American Trade Schools, the focus is on providing practical HVAC skills that help London students move confidently from training into reliable, local roles. With training that covers both technical systems and workplace professionalism, you’re not just learning the basics, you’re preparing for a flexible, lifelong trade.

If you’re training to become an HVAC technician, understanding how cooling systems work is one of the first big steps. These systems do more than just blow cold air. At the centre of it all is the refrigerant cycle, which quietly manages how heat is moved from one place to another. Whether you’re fixing systems in homes or working on commercial equipment, this cycle helps keep indoor environments comfortable, especially during warm summer days in places like London.

When you take an HVAC diploma in London, this topic won’t just be something you read about. You’ll see how each part connects in live setups, learning how a small pressure change can affect the whole system’s performance. It’s not just about knowing where parts go. It’s getting your hands on the tools, taking things apart, and understanding how everything works together. If you’re looking at a real career in HVAC, this is where that knowledge begins.

What Is The Refrigerant Cycle?

An HVAC system has one job: to move heat. During the summer, that means taking heat from inside a space and moving it outside. The refrigerant is what makes that happen. It’s a special fluid that absorbs and releases heat as it moves through the system.

This whole process is called the refrigerant cycle, and it has four main parts:

1. Evaporation – Inside the building, the refrigerant picks up heat and changes from a liquid into a gas.

2. Compression – The gas moves into the compressor, where it gets squeezed. That raises its pressure and temperature.

3. Condensation – Once compressed, the hot gas flows into the condenser coil outside the space. It releases heat and turns back into a liquid.

4. Expansion – The liquid passes through an expansion valve, where pressure drops and it cools down before starting the cycle again.

All four stages work together in a loop. Without the cycle, the system can’t cool the air or control humidity properly. When training in an HVAC program, you get to see each part in action. You’ll learn how to tell when something’s off. If a system isn’t blowing cool air, for example, it might mean something’s wrong with how the refrigerant is flowing. Seeing these examples in a real setting helps the knowledge stick.

Detailed Breakdown Of The Refrigerant Cycle

Let’s look closer at what’s going on in each part of the cycle. Understanding how and why each step happens can make it easier to troubleshoot systems once you’re out in the field.

Evaporation

This step happens in the evaporator coil, which sits inside the building. As warm indoor air passes over the coil, the refrigerant inside absorbs that heat. The refrigerant then changes from a cold liquid into a warm gas. When this happens, the air coming out of the vents feels noticeably cooler.

Compression

Once the refrigerant gas leaves the evaporator, it goes into the compressor, usually found in the outdoor unit. The compressor squeezes the gas tightly, making its temperature and pressure rise. This is like pressing air into a bike tire. It gets hotter as you compress it.

Condensation

Next, that hot, high-pressure gas travels through the condenser coil. This part is also outside. As outdoor air blows over the coil, the refrigerant releases its heat and turns back into a liquid. That released heat is pushed outside the building where it doesn’t affect the indoor temperature.

Expansion

The cooled liquid refrigerant then flows through an expansion valve before heading back inside. At this point, the pressure drops quickly, cooling the refrigerant even more. Now it’s ready to start the whole process again in the evaporator coil.

Training in a real HVAC lab helps you recognize each of these transitions. You’ll learn how a clogged expansion valve can disturb the balance or how poor airflow over the coils can reduce system efficiency. By the time you’re working on actual jobs, these signs are easier to catch—and fix.

Why Understanding the Refrigerant Cycle Matters

Once you start working on real equipment, knowing how the refrigerant cycle works helps you figure out why something isn’t cooling or heating the way it should. Every HVAC system, from residential ACs to large commercial units, depends on this cycle. The stronger your understanding of it, the quicker you’ll be able to spot what’s wrong and fix it.

In London, where summer can bring a mix of muggy humidity and strong heat, it’s especially important that HVAC systems work well. Locals rely on them to stay comfortable, and if the refrigerant cycle is off, even a little, the system may run poorly or not at all. As a future technician, it’s part of your job to understand how to read a system and explain to homeowners or businesses what’s going wrong—and how to fix it.

During your training, you’ll work through similar problems in a classroom and lab setting. You’ll be taught how to:

– Measure superheat and subcooling to check if the system is balanced

– Read gauges to spot blocked parts or low refrigerant levels

– Figure out if a compressor is losing efficiency or if trouble in the coils is affecting cooling

All of this is part of the HVAC program and gets taught through both theory and live demonstrations. That way, when you step into the field, you’ll already know what to expect.

Career Benefits of Learning the HVAC Cycle

Being confident in how the refrigerant cycle works helps you solve real problems, which is exactly what employers want. You’ll also have a better sense of how everything connects—from airflow to pressure—and that lets you do more than just follow steps. It lets you work smarter and with more independence.

In London, tradespeople that specialize in HVAC are in steady demand. Older properties are getting upgrades, and new buildings are being added all the time. That means more jobs where heating and cooling matter, giving you options once your training is done. Whether you see yourself in residential homes, commercial shops, or servicing units across different parts of the city, the job opportunities are out there.

Hands-on training builds your ability to think on your feet. You won’t just learn what a coil or a valve does. You’ll learn to read how a system performs in real time, sometimes even pin-pointing an issue just by listening to a unit run. That kind of instinct grows out of repetition and learning the whole system—not just the parts in isolation. It sets you apart when applying for jobs and lets you start your career with confidence.

Your HVAC Future Starts With the Right Training

The refrigerant cycle is one of the first things you’ll come across in HVAC training, and that’s because it drives everything else. When you understand how refrigerant changes form and flows through the system, you start to see how heating and cooling really work.

Getting to work on real HVAC equipment helps you figure things out faster. You’ll learn how a small gauge reading can show a bigger problem, or why replacing one part could affect the whole system. It also gives you the words and real-world experience to answer customer questions and explain your work clearly.

If you see yourself starting a career in HVAC in London, this is one of the most important concepts to learn early. It’s not just about cooling a space. It’s about knowing how each step in the cycle leads to comfort and safety for the people who use that space every day. And it sets the stage for a solid, hands-on future in one of the trades that’s always in demand.

HVAC (Heating, Ventilation, and Air Conditioning) systems are integral to maintaining comfort in homes, offices, and other buildings. If you’re currently in HVAC technician training or considering this career path, it’s necessary to understand the various systems you’ll encounter in the field. 

Remember, each type of HVAC system offers unique opportunities for technicians. Becoming proficient in these systems ensures you can handle various situations and meet your future clients’ needs. This blog post highlights five common types of HVAC systems you should be familiar with as a budding technician.

1. Be Familiar With Split Systems During and After Your HVAC Technician Training 

Split systems are the most prevalent type of HVAC system in residential settings. Just as we highlighted in our HVAC technician courses at NATS, they are called “split” because they consist of components distributed both inside and outside the home. 

The typical setup includes an outdoor unit containing the compressor and condenser coils and an indoor unit that houses the evaporator coils and air handler. This system is often paired with a furnace or air handler that circulates air throughout the building. As an HVAC technician, you must master both components’ installation, maintenance, and repair.

2. Hybrid Systems

Hybrid systems function similarly to split systems with a twist — they incorporate a heat pump that can provide heating and cooling. This system uses a furnace and a heat pump, which helps save on energy costs. 

The heat pump operates on electricity and can heat and cool your home. Still, during colder weather, the system switches to furnace mode, usually powered by gas, making it more energy-efficient. Training in hybrid systems will involve understanding how to switch between the two energy sources seamlessly and efficiently.

3. Ductless Mini-Split Systems

Ductless mini-splits are becoming increasingly popular due to their efficiency and the ability to control temperatures in individual rooms. These systems do not require ductwork; they have an outdoor compressor, condenser, and one or more indoor air-handling units.
