Short answer: call Aire One Heating & Cooling at 310-HEAT (310-4328), or 416-460-5300. The line is open 24 hours a day, every day of the year, and a real person answers, not an answering machine. Aire One is licensed and insured, has been serving Ontario since 1990, and is headquartered right here at 2800 John Street in Markham, so a technician can be dispatched to your home fast. Below is exactly what to do from the moment the heat goes out.

• Emergency line: 310-HEAT (310-4328). Open 24 hours, every day, answered by a real person.
• Main office: 416-460-5300. The Markham head office at 2800 John Street, Unit 9.

Stay Safe and Warm While You Wait

Once help is on the way, a few simple steps keep your household safe and comfortable until the technician arrives:

• If you smell gas, leave now. Do not flip switches or search for the source. Get everyone outside and call your gas provider or 911, then call for repair from a safe distance.
• Suspect carbon monoxide? Get out. If a CO alarm sounds, or anyone feels dizzy, nauseous or has a headache, leave the home and call for help. A cracked heat exchanger can release CO.
• Keep the heat you have. Close doors to unused rooms, keep exterior doors shut, and layer up with blankets and warm clothing.
• Heat safely. Use only proper space heaters with room to breathe around them. Never use an oven, stovetop or barbecue to heat the home.
• Do not keep resetting the furnace. Repeatedly restarting a furnace that keeps failing can make the problem worse. Leave it off and wait for the technician.

Not sure yet whether it is a true emergency, or want to try a couple of safe checks first? Our full Markham furnace repair guide walks through the warning signs and the simple things to check before you call.

Fast Response, Honest Repair

Speed is only half of a good emergency furnace repair in Markham. When an Aire One technician arrives, they inspect the furnace to find the real cause, not just the symptom, then explain what is wrong and what it will cost before any work starts. Repairs are done by trained, bonded technicians using quality parts, so the fix holds and you are not calling again next week.

A real person on the phone, a trained technician at the door.

Because the trucks are stocked with common furnace parts, most repairs are completed on that first visit. And because dispatch runs around the clock, a furnace that quits on a Saturday night in Markham gets the same fast response as one that quits on a Tuesday morning.

Avoid the Next Emergency

The best emergency call is the one you never have to make. Most no-heat breakdowns build up from small faults a yearly tune-up would have caught. Once your heat is back on, ask about an Aire One maintenance plan so next winter does not start with a 2 AM phone call. As a family business, the goal is to keep you out of the cold in the first place.

We serve Markham and the surrounding communities, including Richmond Hill, Thornhill, Vaughan, Scarborough, North York and Toronto.

Furnace Replacement

Best HVAC Contractor for Furnace Replacement in Markham

Replacing a furnace is a fifteen to twenty year decision. Here is how to know when it is time, which brands to consider, and why Markham homeowners trust Aire One to size and install it right the first time.

A furnace replacement is not a small buy. Done right, the new unit heats your Markham home for the next fifteen to twenty years. Done wrong, an oversized or badly installed furnace wastes fuel, wears out early and never quite keeps the house comfortable. This guide walks through when replacement beats another repair, which brands are worth considering, how financing works, and why the contractor you choose matters as much as the furnace itself. Aire One Heating & Cooling has been sizing and installing furnaces across Ontario since 1990, from our headquarters right here at 2800 John Street in Markham.

Signs It Is Time to Replace, Not Repair

A good contractor will tell you honestly whether a repair will do or whether you are better off replacing. These are the signals that usually tip the decision toward a new furnace:

• The furnace is 15 or more years old. Most gas furnaces last up to about 20 years. Past 15, efficiency drops and breakdowns get more frequent and more expensive.
• Repair costs are climbing. When a single repair approaches a large share of the price of a new unit, or repairs are becoming a yearly event, replacement is usually the smarter money.
• Utility bills keep rising. An aging furnace burns more fuel for the same heat. A new high-efficiency unit can meaningfully cut that monthly cost.
• Visible rust or cracks on the body. Corrosion or cracking is a sign the furnace is breaking down physically, and a cracked heat exchanger is a safety concern.
• Uneven heating. If some rooms never warm up no matter what the thermostat says, the furnace may no longer be sized or working right for the home.
• Changed cycling patterns. A furnace that turns on and off more often than it used to is straining, and that pattern rarely improves on its own.

If you smell gas or suspect a cracked heat exchanger, shut the furnace off, leave the home, and call from outside. That is not a wait-and-see situation.

Up to 20 YearsTypical lifespan of a quality gas furnace

Up to 100%Financing available on new systems

Brands, Rebates and Financing

Part of picking the best contractor is being offered the right furnace, not just the one unit they happen to stock. Aire One carries a wide selection of top brands, including Carrier, York and Navien, so the furnace is matched to your home rather than the other way around. A proper quote should also help you take advantage of the savings available on a new system:

• Rebates. Upgrading to an energy-efficient furnace can qualify for factory and utility rebates that lower the up-front cost.
• Financing. Aire One offers up to 100% financing on the systems it installs, so a failed furnace does not have to mean a large lump-sum payment.
• Payment flexibility. Choose a low monthly payment, defer payment, or rent the equipment, whichever fits your household best.
• Warranty. New systems come with a strong manufacturer warranty for years of worry-free heating. Ask your advisor for the specific terms on the model you choose.

Why Your Furnace Replacement in Markham Depends on the Contractor

The same furnace, installed two different ways, gives two very different results. Correct sizing, clean ductwork connections and a proper commissioning are what turn a good unit into a comfortable, efficient home. That is where an experienced contractor earns its place:

What matters in a replacement	Aire One in Markham
Honest repair-or-replace advice	Yes. A comfort advisor assesses whether repair will do before recommending replacement.
Right-sized to the home	Yes. A free Total Home Assessment sizes the furnace to your house, not a rule of thumb.
Choice of quality brands	Yes. Carrier, York and Navien, plus Carrier Factory Authorized installation.
Affordable to finance	Yes. Up to 100% financing, with monthly, deferred or rental options.
Experienced installers	Yes. Bonded, factory trained technicians, installing furnaces since 1990.
Actually local	Yes. Headquartered at 2800 John Street, Unit 9, in Markham.

What a Furnace Replacement Looks Like

A good replacement starts long before the new furnace arrives. An Aire One comfort advisor visits your home, assesses your heating needs and the existing setup, and sizes the unit to the house. You get a clear quote with the brand options, the rebates you qualify for, and financing laid out before you commit. On installation day, factory trained technicians remove the old furnace, install and connect the new one, and make sure it is running correctly before they leave. No guesswork, no pressure, just a properly installed furnace.

A furnace sized to the home and installed to run efficiently for years.

Because the furnace is sized and commissioned properly, you get the efficiency the manufacturer promises, not a powerful unit that short cycles or an undersized one that never keeps up. That is the difference a careful contractor makes over the fifteen to twenty year life of the system.

More Than Just Furnaces

While you are upgrading, it is worth knowing that Aire One handles the rest of the home comfort system too. From our Markham headquarters we install and service furnaces and central heating, air conditioners and ductless systems, heat pumps, water heaters and tankless units, plus indoor air quality equipment. Replacing a furnace and an aging air conditioner together, for example, is often the more efficient and cost-effective move.

We serve Markham and the surrounding communities, including Richmond Hill, Thornhill, Vaughan, Scarborough, North York and Toronto.

When you search "furnace repair near me" in the middle of a Markham cold snap, you do not want a directory of forty companies. You want one that answers, shows up, and actually fixes the problem. This guide does two things: it helps you catch furnace trouble before it becomes a 2 AM no-heat emergency, and it shows you what to look for in a repair company. Aire One Heating & Cooling is headquartered right here at 2800 John Street in Markham, we have been serving Ontario since 1990, and our emergency line runs 24 hours a day, every day of the year.

Signs Your Furnace Needs Repair

Furnaces rarely die without warning. They usually complain first. If you notice any of these, book a repair before a small fault turns into a cold house full stop:

• Climbing energy bills. A furnace losing efficiency burns more fuel to make the same heat. A sudden jump with no change in weather or usage points to a system working too hard.
• Strange or loud noises. Banging, rattling, screeching or persistent clicking are not normal. They can signal a cracked heat exchanger, a failing blower motor or ignition trouble.
• Unusual smells. A burning or musty odour that does not fade, or any smell of gas, needs attention now. If you smell gas, leave and call from outside.
• Poor air quality. More dust, dryness or stuffiness than usual can mean the furnace or its filtration is no longer doing its job.
• The furnace short cycles. If it switches on and off repeatedly without finishing a full heating cycle, something is forcing it to shut down early.
• Cold spots around the home. Rooms that never quite warm up point to airflow, distribution or capacity problems.
• It needs repairs often. A furnace that keeps breaking, especially an older one, is telling you something. Frequent fixes add up fast.

Any one of these is worth a call. Several together usually mean the furnace is near the end of a heating cycle it cannot finish on its own.

What to Check Before You Call

Some no-heat calls have a simple fix you can try safely in a minute. Before you book a technician, rule these out:

• The thermostat. Confirm it is set to heat, the target temperature is above room temperature, and the batteries are fresh.
• The breaker. A tripped breaker cuts power to the furnace. Reset it once. If it trips again, stop and call.
• The furnace switch. The furnace has its own power switch that looks like a light switch nearby. Make sure it was not flipped off by accident.
• The air filter. A filter clogged solid can choke airflow enough to shut the system down. If it is filthy, replace it.
• The furnace door panel. Many furnaces will not run unless the front panel is seated properly.

If none of that brings the heat back, do not keep resetting the system. That is the moment to call a technician.

Breakdown Prevention and Fewer Repair Costs
When you schedule an annual HVAC inspection, you reduce the chances of breakdowns or problems requiring expensive repairs. Service appointments range from $150 to $500 and could go even higher if you require any replacement parts. Yearly check-ups are often less than $100 and help to prevent problems from occurring.

Protect Your Warranty
When submitting a warranty repair claim, most manufacturers request documentation of yearly maintenance from a credible HVAC technician. Certain components of your HVAC system are costly so investing in a yearly maintenance schedule to keep it backed under warranty is a good decision.

Extend System Lifespan
Regular maintenance increases the lifespan of your system, lowering the possibility that you’ll have to spend a lot of money on HVAC installation anytime soon. It’s similar to how annual check-ups may help humans live longer; only your HVAC doctor comes to your house.

Protect Your Family
Regular maintenance prevents dust and other impurities from blocking your HVAC system. When you perform regular maintenance on your HVAC system, you protect your family from potentially dangerous impurities in your home’s air.

Increased Energy Efficiency
A well-functioning HVAC system, of course, implies cheaper utility expenses. If your system is clean and the parts are working properly, your HVAC system will not have to work as hard to cool the rooms in your house. Similarly, an expert HVAC technician can recalibrate your thermostat settings to guarantee optimal operation.

Maintain Optimum Comfort
You rely on your HVAC unit to keep your home comfortable all year. Maintaining your system annually allows it to create and distribute warm or cold air more uniformly and reliably. Regular maintenance from a licensed HVAC technician will also reduce the likelihood of HVAC sounds or odors interfering with your quality of life.

Would you like to make sure your HVAC system is as efficient as possible?

At Aire One Heating and Cooling we sell, finance, and rent furnaces across Southern Ontario, so when you ask whether to buy or rent a furnace we have no reason to push you toward one option over the other. This guide lays out the trade-offs plainly so you can decide what fits your home, your budget, and how long you plan to stay.

Buy or rent a furnace? The comparison at a glance

How much does it cost to buy a furnace in Ontario?

The installed price of a new high-efficiency gas furnace from Aire One depends on the size of your home, the efficiency rating (AFUE) you choose, and whether your existing ductwork and venting need any work. Two-stage and modulating furnaces sit at the higher end of the range; single-stage units at the lower end. Ask for a written quote so you are comparing the same furnace across purchase, financing, and rental.

If you would rather not pay the full amount at once, financing spreads the purchase over a fixed term with a set monthly payment, and you still own the furnace at the end. Seasonal promotions and rebates can also bring the purchase price down, so it is worth checking what is available before you decide.

How much does it cost to rent a furnace in Ontario?

Aire One furnace rentals are a fixed monthly fee for the length of the rental term, with no down payment and automatic credit approval. The monthly fee covers the equipment, installation, and all repairs for the life of the agreement. Because the fee runs for the full term, the total you pay over those years is higher than the purchase price of the same furnace. That is the core trade-off when you buy or rent a furnace: cash flow and convenience now, in exchange for a higher total cost later.

Pros and cons of buying a furnace

Advantages of buying

• Lowest lifetime cost. Once the furnace is paid for, your only ongoing costs are gas, filters, and annual maintenance.
• You own it. No agreement follows the house, which keeps a sale simple and can be a selling point for buyers.
• Full choice of equipment. Pick the brand, efficiency rating, and features that suit your home, from a basic single-stage furnace to a modulating high-efficiency unit.
• Warranty coverage. New furnaces come with a manufacturer parts warranty, and a maintenance and protection plan can add labour coverage and annual tune-ups.
• Financing is available. If the upfront price is the only thing holding you back, financing gives you a fixed monthly payment without giving up ownership.

Disadvantages of buying

• Higher upfront cost. Even with financing, you are committing to the full purchase price.
• Repairs outside warranty are on you. After the warranty period, or for items it does not cover, you pay for parts and labour unless you have a protection plan.
• Maintenance is your responsibility. Skipping annual service can void the warranty and shorten the furnace’s life.

Pros and cons of renting a furnace

Advantages of renting

• No upfront cost. If your furnace fails in January and you do not have the cash on hand, a rental gets heat back into the house right away.
• All repairs included. Parts, labour, and emergency calls are covered for the term, with 24-hour emergency response.
• Predictable monthly bill. One fixed fee, paid by automatic bank withdrawal, with no surprise repair invoices.
• Equipment replaced at end of term. When the agreement ends you can have the unit replaced with a new one, or take the option to buy it.
• Free removal of your old equipment. Aire One removes and returns your existing furnace where applicable.

Disadvantages of renting

• Higher total cost. Add up the monthly fee over the full term and you will pay more than the furnace would have cost to buy.
• Long-term agreement. Rental terms run for years, and ending early usually means a buyout.
• Limited choice. You get the equipment the rental provider offers, and only that provider services it.
• The agreement follows the house. When you sell, the buyer takes over the rental. Some buyers see that as a negative and negotiate on price, or ask you to buy out the contract before closing.

Is renting a furnace a good idea?

Renting makes sense in a few specific situations. If your furnace has just died and you cannot cover a purchase or qualify for financing, a rental is the fastest way to restore heat with no cash down. If you plan to move within a few years and do not want to sink money into a furnace you will leave behind, a rental keeps your outlay small. And if you value never having to think about repair bills, the all-inclusive monthly fee removes that risk entirely.

Outside of those cases, buying usually wins the buy or rent a furnace debate. If you expect to stay in your home for the next several years, the lower lifetime cost of owning the furnace outweighs the convenience of renting, and financing solves the upfront-cost problem without the long-term agreement.

What happens to a rented furnace when you sell your home?

An Aire One rental agreement is transferable to the new homeowner, and no lien is placed against the house, so a rental does not block a sale. The buyer simply takes over the monthly payments. In practice, some buyers prefer a home with an owned furnace, so it is worth discussing with your real estate agent whether to keep the rental, transfer it, or buy the unit out before listing. The buyout option is built into the agreement, so you have that choice at any point. This is the part of the buy or rent a furnace decision that most homeowners overlook until they list the house.

Should you buy or rent a furnace? A simple way to decide

Ask yourself three questions. How long will you stay in this home? If the answer is more than a few years, buying almost always costs less. Can you pay upfront or qualify for financing? If yes, ownership is within reach and there is little reason to rent. Do you want zero repair risk and one fixed bill? If that matters more to you than total cost, renting is a reasonable choice. Most Ontario homeowners who plan to stay put land on buying, often with financing; homeowners in a cash crunch or a short-term situation land on renting.

How Aire One furnace rentals work

Our rental plans include automatic credit approval, no down payment, all repairs included, 24-hour emergency response, and service by Aire One’s own technicians. Payment is by automatic bank withdrawal, the agreement is transferable to a new homeowner with no lien on the house, your old equipment is removed and returned free where applicable, and at the end of the term the equipment is replaced, with an option to buy. If you would rather own, our team can quote the same furnace as a purchase or on a financing plan so you can compare whether to buy or rent a furnace side by side.

A limit switch also known as a fan limit is an electromechanical element that detects the temperature on a furnace. It is located under furnace’s supply plenum and tells the fans on the blower when to turn on and off.

A limit switch on a furnace uses gas or heating oil for power. The blower will turn on and off depending on the temperature. If it is starting to get too hot inside of the furnace, the switch will also be able to detect that and cut it off. Once an appropriate temperature has been reached inside of a home, the burners will turn off. However, the limit switches will continue to bring out as much heat as it can by blowing for a bit longer.

Over time, a problem may occur with the limit switch. Sometimes it can be something as small as the sensor on the switch becomes dirty. Once it gets dirty it will not work accordingly. The filter in the furnace may also become clogged which in turn will heighten the temperature. This will trigger the sensor to not act the proper way. Another issue you may encounter with the limit switch is that the blower motor may overhear and stop working.

It is important to keep your limit switch in a proper shape by scheduling the annual maintenance with Aire One, an experienced heating and cooling company, operating in Ontario for over 30 years.

When you’re in the market for a new HVAC system, it can be hard to know what to look for. Aire One, a heating and cooling company with over 30 years of experience, is here to help you with questions about what the efficiency ratings mean for your home and your budget.

Seasonal Energy Efficiency Ratio (SEER)

SEER is the ratio between how much energy it takes to run an air conditioning unit compared to the output of the cooling unit. This number is based on an average temperature of 82 degrees Fahrenheit.

Heating Seasonal Performance Factor (HSPF)

HSPF is similar to SEER in that it measures how efficient the heating system is. The HSPF rating available for heating units sold in the United States is between 8 and 10 for heat pumps. The higher rating means the heating unit is more efficient.

Annual Fuel Utilization Efficiency (AFUE)

The AFUE for your furnace is similar to the miles-per-gallon measurement for your automobile. This rating provides information on the heat output as compared to the money spent on fuel.

Minimum Efficiency Rating Value (MERV)

MERV is a rating that was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers. It’s an important number that rates how efficient your HVAC’s air filter is when it comes to removing dust, particles and debris. The rating scale is from 1 to 16, with the higher number being the most efficient.

There’s a lot of information to learn when you’re searching for a new HVAC system. Professionals at Aire One can help you pick out just the right unit to keep your house at the right temperature all year long. We can assist you with a variety of options like furnaces, heat exchanges and central heating units.

When you don’t have HVAC annual maintenance done by professionals from Aire One, a heating and cooling company operating for over 30 year, lots of bad things can happen.

Let’s Talk About the Risks

As it happens sometimes, at the worst possible time your HVAC system could fail. You will be left shivering in the cold, or sweating in the heat. To say it is uncomfortable for everyone in your family would be an understatement.

The annual maintenance costs are minimal compared to how much it might cost to repair or replace the whole HVAC unit.

The inefficiency of your system will be compromised. What this means is your thermostat may labor to keep things operating properly. The system is stressed by things like inappropriate coolant levels, the inability to push air through the system efficiently, and more.

Repairs and replacements to your HVAC components are costly. The key to a long life for these systems is to have it inspected, cleaned, and components replaced when needed. Utility bills will be lower too.

Aire One as your heating and cooling company is your best friend when it comes to keeping everything working properly. It will also extend the time between repairs, and replacements.

What to Expect from the Heating and Cooling Company

Trained technicians will do several critical things when they arrive at your home. Their goal will be to extend the life of your HVAC system, and avoid its failure. The bonus is the technicians are going to make your home more comfortable too.

Your home will be cleaner after the professionals at Aire One have done their job. They will inspect and clean the filter, coil, and blower. Without this annual cleaning mold, mildew, germs, and just plain dirt will build up. This can lead to a dirtier home. You don’t want cleaning to be a bigger job because you failed to get an annual maintenance call from the heating and cooling company.

If you have not had your HVAC system maintenance done during the past year, it’s time to pick up the phone and call. Contact us today and have your HVAC system checked.

During the winter months, you depend on your furnace to keep your home comfortable and to keep you healthy. In turn, your furnace depends on you to make sure everything is working properly. A key component to look at is the furnace heat exchanger. If this breaks down, the consequences can be tragic.

What is a Furnace Heat Exchanger?

A furnace heat exchanger is a thin metal sheet that acts as a shield between the combustion chamber and the blower. The combustion chamber is a sealed chamber where fuel is ignited and mixed with air to make heat. This air, however, is full of flue gases, that can be dangerous to breathe. As the chamber heats the exchanger up on one side, the blower blows clean air across its surface on the other and distributes the heated air across your home.

Troubles With a Furnace Heat Exchanger

The biggest source of trouble is old age. After 10 years, the continuous expanding and contracting of the heat exchanger starts to make the metal more brittle. After 15-20 years, the metal will crack or snap, and the seal on the combustion chamber will be broken. This can potentially lead to carbon monoxide poisoning if there are also combustion issues. A professional from Aire One, a heating and cooling company operating in Ontario can tell you if there are signs of cracks.

How to Take Care of a Furnace Heat Exchanger

The first thing you should do is know when you need to replace your exchanger. When your exchanger reaches the 15-year mark, ask your technician about replacing it during your annual furnace tune-up. During your tune-up, the technician will examine the exchanger to see if it’s in working order. If not, don’t replace it yourself. If it isn’t installed by a professional, it could be scratched or cracked before you even use your furnace once.

Ultimately, it’s up to a licensed HVAC technician from a reputable heating and cooling company such as Aire One to determine your furnace heat exchanger’s condition. Contact us today to schedule a furnace tune-up and exchanger inspection.

Any heating and cooling company will tell you; a furnace air filter is critical to keeping your home clean and your hvac system operating properly. In the past the use of disposable air filters were the standard. Today, many families are choosing a washable furnace filter instead.

Get to Know Your Options

If you have been using the disposable type of air filter, you want to be educated about your options for a washable air filter. Just think about how it will feel to purchase one filter instead of having a stack of them stored in the garage, and replacing them every three month. Simply washing your new filter monthly will give your family more comfort and better health.

When you switch to a washable furnace filter you are not adding fiberglass, polyester, cardboard, or cotton to your landfill footprint. If you are environmentally conscious, considering a washable furnace filter may be no brainer. Aire One licensed technicians can discuss your options with you.

MERV Ratings

Select the proper MERV (Minimum Efficiency Reporting Value) rating to fit your needs. The term MERV is an industry standard developed in 1987. The higher the number indicates the best level of filtration.

The MERV scale ranges from 1-16. It’s best to ask experts at Aire One, a heating and cooling company with over 30 years of experience, to give you advice about what is right for your home.

Cleaning Washable Furnace Filters

These “permanent” filters need to be cleaned regularly. For most people this means a monthly cleaning, but the American Lung Association says you must clean it every three months at a minimum.

Simply place the dirty filter on a level surface with the dirty side up. Vacuum carefully to pick up as much of the dirt, debris, and dust as you can. Take the vacuumed filter to a large utility sink or bathtub, and thoroughly wash with warm water. It can be helpful to use a sprayer to increase the water pressure. Do not use soap on the filter, and let it dry before returning to the furnace.

If you have any questions what type of filters are best for your furnace, contact us today.
