Furnace Types
- Available Technology
- Fueling Options
- How a Furnace Works
- Types of Furnaces: Single Stage, Two-Stage and Modulating
When choosing a new furnace, you’ll typically be deciding between three main types: single-stage, two-stage, and modulating furnaces. Each type offers reliable home heating, but they differ in how they deliver heat, their energy efficiency, and their price. The best furnace for your home will depend on your budget, comfort preferences, and efficiency goals.
Consider not only upfront cost but also long-term operational costs and compatibility with other home systems like smart thermostats or humidifiers.
Single Stage Furnace:
Single stage furnaces are the most basic and commonly installed type of furnaces. This type of furnace only has one d setting. When on, your furnace operates at the maximum flame setting—there is no middle ground between the system being on or off.
This type of furnace often comes at a lower up-front cost but is not the most efficient option.
Single-stage furnaces are best suited for smaller homes or homes where precise temperature control is less critical. Expect more noticeable temperature fluctuations.
Two-Stage Furnace:
Two-stage furnaces have two different settings when your furnace is on, a high setting as well medium intensity setting to deliver a wider range of operation. This type of furnace can help to give you more temperature control in your home.
The furnaces are more expensive than the single stage options but are generally more energy efficient as there are different levels of heating available.
Two-stage furnaces are ideal for medium-to-large homes and for homeowners who want a balance between comfort and operational cost. They could reduce temperature swings and potentially improve indoor air quality by running longer, lower-speed cycles.
Modulating Furnace:
Modulating furnaces offer an advanced type of heating technology that delivers more even heating throughout your home. With a modulating furnace, the flame increases and decreases in finer increments to help maintain your home’s temperature. This reduces temperature fluctuations and helps meet your comfort needs more precisely.
Modulating furnaces are the most expensive to purchase upfront but will deliver consistent heating most efficiently.
Modulating furnaces are best for homeowners seeking precise comfort, very quiet operation, and optimized energy efficiency. These units often integrate seamlessly with smart thermostats for advanced control.
Hybrid (Dual-Fuel) Systems
Popular in BC and Ontario, these pair an electric heat pump with a gas furnace. The system automatically switches to gas during extreme cold, optimizing for the lowest utility rate in your province.

Energy Tip
Before buying check the equipment’s Annual Fuel Utilization Efficiency or AFUE rating. The higher the AFUE is the more efficient your furnace is. As of 2026, most new gas furnaces sold in Canada must meet a minimum 95% AFUE rating. This ensures that regardless of your province, your system meets federal energy-efficiency standards.
Technology Found in Today’s Furnaces
Modern furnaces include advanced technology designed to deliver consistent comfort and operate more efficiently. Here are some of the innovations you may find in today’s models:
Understanding these technologies helps homeowners make informed decisions and avoid buying features they may not need.
Condensing Technology
A condensing furnace uses a secondary heat exchanger to capture more heat from exhaust gases before they leave the system. This process allows the furnace to make better use of the fuel it consumes and maintain high efficiency.
Electronically Commutated Motors (ECM)
An Electronically Commuted Motor (ECM) is a motor technology in forced air heating applications that works to reduce the electrical consumption of the furnace motor. This technology can reduce your furnace’s electrical consumption by as much as 60% over a standard motor. These motors work with the furnace, adjusting speed to provide adequate air flow. Less electrical consumption results in a reduction of air noise in your home.
Electronic Ignition
Modern furnaces come with electronic ignition, which is a technological advancement replacing the pilot light system. With electronic ignition, fuel is only used when it is time to start the furnace. In older technology, a pilot light would use a small amount of fuel continuously, resulting in additional energy consumption.
Intelligent Digital Electronics and Wi-Fi
New furnaces have a digital integrated control board that control all the functions related to the heating/cooling operations in your home. It controls the gas valve, the igniter, the flame sensing circuit and blower fan. The control board also communicates with standard thermostats, smart learning thermostats, air conditioners and humidifiers.
Energy Tip
Ceiling fans aren’t just for the hot summer days! Switching your fans to spin clockwise in the winter help allows the warmed air to circulate throughout your home.
Different Fueling Options
Before you purchase a new furnace, consider which fuels are available in your area. You should review advantages and disadvantages of your available energy sources.
| Fuel Source | Fuel Efficiency | Operating Cost* | Cost to Install |
|---|---|---|---|
| Gas | High | $ | $ |
| Propane | High | $$ | $ |
| Oil | Medium | $$ | $$ |
| Electric | High | $$$ | $ |
Pro Tip: Fuel availability varies significantly by province. While natural gas offers the lowest operating costs in urban centers across Ontario and the West, high-efficiency electric or propane systems are excellent alternatives for rural properties or areas without gas main access.

The Heating Cycle: How Your Gas Furnace Works
Your thermostat monitors the indoor temperature. When it drops below your programmed setting, it sends a signal to the furnace control board requesting heat.
The control board activates the induced draft motor to clear the heat exchanger. Once a pressure switch confirms safe airflow, the igniter is activated to prepare for fuel release.
Fuel is released and burners ignite in sequence, warming the heat exchanger. A flame sensor continuously monitors this process, allowing fuel flow only while a healthy flame is present.
Once the heat exchanger reaches the target temperature, the blower fan activates. Warm air is pushed through your home’s ductwork while limit switches monitor internal temperatures for safety.
When the thermostat reaches its set temperature, it signals the control board to shut off the gas. The blower fan continues briefly to capture any remaining heat before the system rests.

- Geological Constraints: Not all soil types or property layouts are suitable for ground-loop installation.
Boilers and Hydronic Heating Systems
A boiler, or hydronic heating system, provides warmth by using a fuel source to heat a fluid—such as water or glycol. This heated fluid is then pumped through the system to various heat emitters, including radiators or in-floor radiant heating loops.
Combi-Units: For homeowners looking to maximize space and efficiency, a “combi-unit” is a high-performance heating source that provides both central home heating and on-demand domestic hot water from a single compact appliance.
Benefits of a Boiler System
- No Ductwork Required: Because they utilize pipes rather than vents, boilers are a primary heating solution for older homes and additions where ductwork is not present.
- Radiant Comfort: Hydronic tubing can be installed under most flooring materials, providing the luxury and consistent warmth of heated floors.
- Space-Saving Combi-Options: Selecting a combi-unit allows you to consolidate your home heating and water heating needs into one efficient system.
- Quiet Operation: Unlike forced-air systems, operational noise is confined to the boiler unit itself and typically cannot be heard throughout the rest of the home.
- Zoned Heating: Hydronic systems allow for precise “zoning,” enabling you to control the temperature of different rooms or floors independently.
Considerations of a Boiler System
- No Central Cooling: Since boilers do not use ducts, they cannot provide central air conditioning. Homeowners often pair boilers with ductless split systems for summer cooling.
- Installation Complexity: Retrofitting a boiler or in-floor heating into an existing home requires specialized plumbing and hydronic expertise.
- Response Time: Hydronic systems can take longer to “ramp up” to a desired temperature compared to the immediate blast of a forced-air furnace.

Installing a New Furnace: Your Questions Answered
The performance of your heating system depends as much on the quality of the installation as it does on the equipment itself. Below are the most common questions homeowners ask when preparing for a furnace replacement.
Can I install a furnace myself?
Even for an experienced DIY enthusiast, installing a modern HVAC system is not recommended. Professional technicians bring specialized knowledge of local building codes, complex electronics, and venting requirements. A self-installed furnace can lead to voided warranties, inefficient operation, or significant safety risks.
What defines a quality furnace installation?
A reputable installation team does more than just swap out equipment; they ensure the system is a perfect match for your home. Key indicators of a professional installer include:
- Proper Needs Assessment: They evaluate your home’s insulation, window efficiency, and sunlight exposure rather than just matching the size of your old unit.
- Precision Sizing: They perform detailed heat-loss calculations. An oversized unit will “short-cycle” and wear out early, while an undersized unit will fail to keep you warm on the coldest days.
- Technical Expertise: They are well-versed in the latest smart home integrations and high-efficiency venting configurations.
How long does a furnace installation take?
On average, a standard furnace installation takes between a half-day and a full day. This timeframe includes the removal of the old unit, the technical installation of the new system, comprehensive safety testing, and a thorough cleanup of the workspace.
What should I expect on installation day?
Most installations are performed by a team of two professionally trained technicians. You can expect:
- Home Protection: Technicians will wear protective booties and lay down floor coverings to protect your carpets and hardwood.
- System Testing: Once installed, the team will conduct a series of tests to ensure the furnace is in sync with your thermostat and cooling systems.
- Full Cleanup: The team will remove all old equipment, parts, and packaging, leaving your utility space cleaner than they found it.
How should I prepare for the technicians?
To ensure a smooth process, please ensure the pathway to your furnace room is clear and the work area is clutter-free and well-lit. For the safety of everyone involved, we recommend keeping children and pets away from the work zone during the installation.
Money Saver Tip
A comprehensive protection plan will include your regular maintenance and cover most unexpected repair costs.
Choosing the Right Thermostat
Your thermostat is the brain of your home comfort system. From simple manual controls to advanced AI-driven communicating units, the right choice can significantly impact your monthly energy savings and equipment lifespan.
Basic Non-Programmable
Economical and straightforward, these units are best for those who prefer manual control. The temperature only changes when you physically adjust the dial or buttons.
Programmable Thermostats
These units allow you to set “schedules” for workdays vs. weekends. They help lower costs by automatically reducing heating or cooling when you are asleep or away from home.
Smart Wi-Fi Thermostats
The gold standard for modern homes. These “learning” thermostats study your habits and adjust temperatures based on occupancy and weather patterns, all controllable via your smartphone.
Communicating Wi-Fi Thermostats
Designed specifically for high-efficiency modulating furnaces. These units talk “back and forth” with your equipment to receive error codes, maintenance alerts, and ensure the system runs at its absolute peak performance.
Enhancing Indoor Air Quality: Whole-Home Humidifiers
The Winter Challenge
Canadians spend approximately 90% of their time indoors during the winter. When your furnace heats outdoor air, the relative humidity drops significantly. This “dry air” makes your home feel colder than it actually is, often leading you to turn up the thermostat—increasing your energy bills without actually improving your comfort.
A whole-home humidifier works directly with your HVAC system to introduce moisture into the air before it circulates through your ducts, ensuring every room reaches the ideal humidity level.
Advantages of a Whole-Home System
Unlike portable units, whole-home systems feature an integrated humidistat that automatically monitors and adjusts moisture levels to maintain peak indoor air quality.
Connected directly to your home’s water supply, these systems never require manual refilling. Most models only need a simple pad change once or twice per year.
A modern, fully integrated HVAC system—complete with IAQ upgrades like humidifiers—is a strong selling point that can enhance your home’s long-term resale value.
Tech Tip
Remember to replace or clean your whole home humidifier pad once or twice each year. This is just as important as replacing or cleaning your furnace filter.
keeping you warm during the cold winter months.
But in order to keep your furnace running at peak efficiency, you’ll have to maintain
it and change the filter on a regular basis.
Furnace filters protect your furnace from dust, hair and other debris that gets drawn
in through the cold air return ducts.
If dirt gets into the furnace, it can increase fuel consumption and maintenance costs while
also reducing furnace life.
Furnace filters also remove dust and allergens from your home which can contribute to improved
air quality for you and your family.
If a filter looks dirty as you pull it out, it needs to be replaced or cleaned.
There are many types and sizes of filters.
Most have something called the MERV rating.
This is a number from 1 to 20 that identifies the effectiveness of the filter.
The higher the MERV rating, the better the filter is at capturing small particles.
A MERV rating between 7 and 13 is ideal for most homes.
Make sure the filter you choose isn’t too restrictive as this can cause your furnace
to work harder which could lead to increased energy usage and shorter equipment life.
The most common furnace filter has disposable pleated paper as the filtration element.
Pleated paper does a good job of removing most household particles and allergens with
a MERV rating of between 6 and 13.
Disposable fibreglass filters are an inexpensive option, but tend to have a lower MERV rating.
Inspect your furnace filter every 30 to 60 days.
The frequency of filter maintenance depends on a number of factors; the type of filter
you’re using, how many people live in the home, the amount of dust and if you have pets,
all affect the filter’s lifespan.
Changing a furnace filter is simple.
First, make sure your furnace is turned off so it doesn’t blow air when you remove the
filter.
Next, locate the filter housing on your furnace.
This is different for each model but you can normally find it between the air intake and
the furnace.
Open the compartment door and slide the filter out.
Compare the size and type of replacement filter with the old one.
Specifications should be printed on the side of the filter.
If size information isn’t printed on the filter frame, measure the filter yourself, rounding
up to the nearest half inch.
Slide the newer, clean filter in place with the arrows pointing towards the furnace in
the direction of air flow.
Secure the compartment cover, then turn your furnace back on.
Now all that’s left to do is set a reminder for your next inspection.
If you need assistance with any furnace maintenance or repair, Call on Reliance.
Furnace Air Filters & Indoor Air Quality
Air filters are the first line of defense for your heating equipment. By capturing dust and allergens, a high-quality filter prevents debris from entering your furnace, maintaining peak efficiency and extending the overall lifespan of your system.
Fiberglass (MERV 1–4)
Captures roughly 20% of large particles like lint and dust. These are designed primarily to protect the equipment rather than improve indoor air quality.
- Replace: Every 30 days
- Best for: Essential equipment protection
Pleated (MERV 6–13)
Captures 70% to 90% of airborne pollutants. These use electrostatic fibers to attract smaller particles like pet dander, spores, and fine dust.
- Replace: Every 90 days
- Best for: Homes with pets, children, or smokers
High-Efficiency (MERV 9–16)
Traps up to 95% of particles down to 0.3 microns, including mold and pollen. These often feature deep 4″–5″ pleated synthetic material.
- Replace: Per manufacturer (often 6–12 months)
- Best for: Allergy sufferers and superior air filtration
Tech Tip
Air filters are categorized according to Minimum Efficiency Reporting Values or MERV ratings. MERV ratings range from 1-20. Air filters with lower MERV ratings will remove a smaller percentage of pollutants. Filters with a MERV between 7 and 12 are considered good quality.
Are you ready for the heating season? A Canadian winter can come in a flash, and you want to make sure that you and your home are ready for the cold before the temperature drops. Just like you don’t wait for your car to stop running before you change the oil, you should not wait for your furnace to break down before you have it inspected. Especially as your furnace ages, some parts become worn or dirty over time such as pilot lights, belts, motor bearings, and the burner assembly. You want to make sure that your furnace is maintained regularly to help avoid a costly breakdown during the winter.
Tech Tip
Be sure to schedule your furnace maintenance in September or October to avoid the rush!
Why should I have my furnace maintained?
- In the middle of a cold winter day is the worst time for your furnace to stop working, you want to make sure any issues are identified earlier
- Even if your furnace does not stop working, it might be performing poorly resulting in more strain on your equipment
- A poorly performing furnace could cost you more to operate
- Replacing a furnace is expensive compared with the cost of a few periodic checkups
Can I inspect the furnace myself?
By all means, check and change your filters, but unless you are a qualified HVAC technician, it is not safe to attempt to fully inspect your own furnace.
Tech Tip
Do not try to open or repair a furnace. Unless you are a qualified furnace technician, never attempt to remove the door or open the furnace in any way. Electronics and anything inside your furnace are for professionals only
Who should maintain my furnace?
There are a few things that you will want to keep in mind when deciding which HVAC company you want to have tune-up your furnace:
- Look for a company with technicians that have a fast response time and avoid those that take days to respond to a call
- Do some online research and read their reviews to see if others have had a positive experience with the company
- Find a company with highly trained technical experts who specialize in different HVAC solutions
- Look at how many service calls the company does each year
What should I do before the furnace inspection?
Before the technician arrives, help ensure safety for everyone by clearing the furnace room and the path to the equipment of any clutter or other items. Replace bulbs to ensure adequate lighting. It is a good idea to have a spare furnace filter on hand. The technician can then check the filter system, and if needed, install the new filter for you. For everyone’s safety, separate and keep your children and pets away from the work area.

Maintaining Your Furnace Filter and Humidifier
Part of making sure your furnace stays running smoothly all winter long and keeps your home comfortable starts with making sure that the furnace accessories are also properly maintained. Here are a few of the common questions you may have about maintaining both your air filter and humidifier:
Why are clean filters important?
You can help to ensure a high level of indoor air quality by ensuring your filters are replaced or cleaned regularly. Air filters help both your indoor air quality and your furnace run smoothly. Because air filters do so many jobs, filling up quickly with pollutants, debris, hair and allergens, they have a short lifespan. They must be replaced or cleaned frequently, to maintain good performance.
Replacing air filters more frequently during heating season helps keep the air flow moving. You could set up calendar reminders for filter checks, or arrange furnace maintenance and leave it to the professionals.
How often should I replace my air filter?
The frequency of filter replacement or cleaning will depend on the kind of furnace you have and the kind of filter it uses. The home environment will also have an impact of filter replacement. Homes with pets, or increased dust/dirt may need to be changed or cleaned more often. In general filters should be changed every three months, when they are dirty or according to the recommendations of your equipment manufacturer. It’s a good practice to keep a supply of filters on hand to make it quick and easy to change dirty filters when necessary.
How many filters are there?
Usually there is only one filter for a furnace, one pad for a humidifier, and one to two filter for a heat recovery ventilator. There may also be a separate filter for your air conditioning, depending on the model and configuration.
Some homes have an electronic air filter, powered by the furnace control board when the circulation blower fan turns on.
How do I replace my furnace filter?
- Turn off your heating equipment – also be sure that your thermostat is set to off
- Locate your old filter – it is usually found in a main vent or behind your furnace
- Determine the size you need –your old filter should have the size printed on the side
- Decide on the type of filter that you want – consider the needs of your family and home
- Find the arrow on your new filter – this will indicate which way it needs to be inserted
- Insert your new filter
Humidifier pad maintenance
Your humidifier pad should also be changed or cleaned periodically and the frequency will depend on the type of humidifier that you have, as well as the quality of the water connected to it. Be sure to ask your service technician about the proper humidifier pad maintenance for your equipment during your regular maintenance.
Preparing Your Home for Winter
Try not to leave it until the last minute when snow is piling up outside. But life happens, and your service company should be happy to undertake a checkup even well into winter. Try to book furnace maintenance for September and October before the rush.
1. Consider a protection plan
Put your furnace inspections and regular service on autopilot, by signing up for a compressive protection plan to make sure you are always covered. Learn more here.
2. Make sure the furnace is turned on
It seems obvious, but it does happen that the furnace gets turned off and not turned back on.
3. Check the batteries & test the thermostat
If your thermostat has batteries, check the batteries. Now might be a good time to also check the batteries in smoke alarms and carbon monoxide detectors. Some people choose to check their batteries twice a year at the same time they adjust their clocks for daylight savings time.
It’s easy to test a thermostat. Just check the temperature level and turn it up about 5 degrees higher. Your furnace should come on within a few minutes. If it does not come on, there is a problem with either the thermostat or the furnace. Change the batteries if applicable and if that does not help, call a professional and have them inspect your furnace and thermostat.
Safety Tip
When you are doing maintenance around your home, be sure to replace the batteries and test both your fire alarm and carbon monoxide detector. This should be done at least twice a year.
5. Change the air filters
Furnace filters, humidifier pads, ventilator filters all require checking and regular replacement. The best way is by changing or cleaning your furnace filter, humidifier pad and any other equipment filters in your system. For more information on filters see the filter section below or click here.
6. Keep intake and exhaust vents & grilles clear and clean
Clutter, dust and dirt are the enemies of your home’s heating, cooling and ventilation system. Clean and unblock areas in front of heating grills, radiators, intake vents and outside exhaust vents.
7. De-clutter the furnace room
Keep your furnace room and all areas around your furnace clean and clutter-free. If your furnace room is also your laundry room, do not hang wet items on furnace equipment as it can create a serious fire risk. Store all items away from your heating equipment and provide clear access to your furnace at all times.
If your furnace is in need of repair, it is important not to leave it. Depending on the problem you are facing ignoring the issue will not only leave you cold this winter, but may also further damage the equipment. For most problems, it is best to call a licensed and trained HVAC technician to come and inspect and repair the system to ensure the system is fixed properly.
For more information about having your furnace fixed, here are a few frequently asked questions for the most common furnace issues:
Furnace Repair FAQs
If it is not working or not working right, the on switch might be off, the breaker may have tripped, the thermostat might be set wrong, and the filter might be very dirty, the air ducts might be physically blocked or the dampers might be closed. If you have checked these items and it still is not working, it is time to call a professional and have it inspected.
If it is blowing cold air your thermostat fan setting might be set to ON. Change it to AUTO so that it only blows when there is warm air to blow.
If your furnace is leaking water, it is usually related to condensation leaking from a blocked or damaged hose used in a high efficiency furnace, air conditioner or humidifier. It might also be the water supply to the humidifier. All leaks should be referred to a qualified technician.
Popping or banging sounds especially if they occur after the blower turns off, are usually caused by expansion and contraction in the ductwork. A squeaking noise during operation may mean worn out fan bearings. A scraping sound could be a blower wheel fault. Tapping may indicate something caught up in the blower blades. Buzzing often relates to a problem with a transformer box. All furnace sounds should be checked by a qualified technician.
Cost increases can be caused by different occupants, usage patterns, or weather, higher fuel prices. If none of this sounds right, check that your filters are clean, your vents are unblocked, and that your thermostat settings are proper. If none of that solves the problem, you might need a cleaning and inspection.
This should really be left to a professional, but carbon monoxide alerts, odours, soot, changes to burner flame and metal discolouration might all point to a cracked heat exchanger. Professional technicians may use a special camera or combustion analyzer to provide a more accurate diagnosis.
There are many different factors that can determine how long a furnace will last including age and operating conditions. Conditions include the kind of furnace, the local climate, proper regular servicing and heavy or moderate usage. Warning signs that it might soon be time to look at new furnaces include increasing repairs, noise, or rust.

With the high price of energy, finding ways to make your home more energy-efficient is top of
mind for all of us. Whether you’re trying to be environmentally friendly or reduce your monthly
utility bills, there are a few things that you can do to help lower your energy consumption. First,
consider upgrading less efficient equipment to a high-efficiency system and schedule
regular maintenance with a trusted and professional HVAC technician. It takes
a lot to keep your heating and cooling equipment running so you want to make
sure that your system is operating smoothly and as efficiently as possible. Second,
be sure to replace your furnace filter regularly. Not only can this help with indoor air quality,
it can also help keep your furnace from overuse. A dirty furnace filter causes your furnace’s
blower motor to work harder to move the warm air throughout your home. That means it takes more
energy for your furnace to keep your home at your preferred temperature. So be sure to follow the
manufacturer’s recommended replacement cycle to help avoid unnecessary energy consumption. Third,
think about upgrading to a programmable or smart learning thermostat. This new type of thermostat
will regulate itself automatically by recording your usage patterns, eventually learning the exact
temperature you like at each time of the day to minimize energy waste. And lastly, consider
implementing zoning options for a targeted temperature in different areas of the home,
directing heat to only the areas where it’s needed, when it’s needed, can make a difference
in your home’s energy use. There are also other simple ways that you can help bring down energy
consumption like ensuring your doors and windows are well-insulated and sealed or by using ceiling
fans to help distribute warmed or cooled air throughout your home. If you have questions
about energy savings in your home or are looking to upgrade to more energy-efficient heating and
cooling equipment call us today. Our knowledgeable team of Home Comfort Advisors are committed to
answering your questions, assessing your needs and will help find the right energy-saving solution
for you and your home. So remember for all of your home comfort needs, Call on Reliance™.
Expert Tips: How to Help Lower Your Winter Heating Costs
Maintaining a warm and comfortable home throughout the Canadian winter doesn’t have to break the bank. By implementing a few strategic changes to your daily habits and equipment, you can keep your energy costs manageable even when the temperature dips.
- Harness Natural Solar Heat
Keep your curtains and blinds open during daylight hours. Even in sub-zero temperatures, the sun provides a powerful natural heat source that can help take the edge off your furnace’s workload. - Invest in ENERGY STAR® Certified Equipment
If you are replacing an aging system, prioritize units with ENERGY STAR® certification. These high-efficiency models are designed to provide maximum warmth while consuming significantly less fuel. - Optimize with Smart Controls
Upgrading to a programmable or smart thermostat allows you to automate temperature setbacks when you are sleeping or away, giving you total control over your monthly energy bill. - Reverse Your Ceiling Fans
Ceiling fans aren’t just for summer. By switching your fan direction to clockwise at a low speed, you create an updraft that pushes warm air trapped near the ceiling back down into the living space. - Layer for Comfort
An easy and cost-effective way to stay warm is to reach for a sweater or a blanket before adjusting the thermostat. Lowering your home temperature by just a few degrees can result in noticeable seasonal savings.
Energy Tip
Upgrading both your furnace and your air conditioner to efficient models at the same time will help you maximize your energy savings.
