“They did a great job in steering me to the correct heat pump and furnace replacement. My furnace was red-tagged by Enercare and my air conditioner had given up the ghost. Great prices comparatively speaking. And great after sales service as well! We had a heat pump issue in the freezing cold weather and they came the same day to correct the issue!

Why Is Your Furnace Not Working?
If you maintain your furnace regularly, it’s easier to spot these common problems before they become bigger issues. Here are the signs we see most often in Toronto homes.
If nothing happens when you raise the thermostat, start with the basics: the thermostat setting, the furnace power switch, and your electrical panel. If all three look fine, the cause may be a failed igniter, a faulty control board, or a safety switch that shut the system down for a reason. That’s when it’s time to call us.
Don’t panic if your furnace isn’t producing enough heat when you turn it on for the first time in a while. A furnace blowing cold air can point to a thermostat set to “fan on,” a dirty filter, a pilot light or ignition problem, a gas supply issue, or leaking ducts.
Is the kitchen freezing while the office feels like a sauna? Uneven heating problems are annoying and costly. Blocked vents, poor insulation, leaky ducts, or a system that isn’t sized for Toronto homeowners can all be to blame.
Furnaces today are built to run quietly. Loud furnace noises like banging often point to delayed ignition; grinding or metal-on-metal sounds can mean a worn blower motor bearing, and screeching may signal a failing belt.
Not all furnace smells are a problem. A dusty smell after the furnace has been off all summer is normal and should fade quickly. A sewage smell, smokiness, or the smell of hot rubber or plastic needs immediate attention.
A leaking furnace is a sure sign of trouble. High-efficiency furnaces produce condensation, so a clogged condensate line or drain is a common cause, but a leak can also point to a cracked heat exchanger. Turn off your furnace and call a technician now!
A furnace that keeps shutting off could be as simple as a thermostat setting or a blocked filter, or it could be overheating or the wrong size for Toronto homeowners.
Modern furnaces use an electronic igniter, while older models rely on a standing pilot light. A cracked igniter, a dirty flame sensor, or a pilot that won’t stay lit will stop your furnace from producing heat. These parts sit right next to the gas supply, so please leave this repair to a licensed technician.
Your gas furnace still needs electricity to run its blower, igniter, and controls. A tripped breaker is an easy fix: reset it once. If it trips again, the furnace or wiring likely has an electrical fault, and it’s time to call us.
Sometimes the furnace is fine, but your thermostat is broken. Dead batteries, a loose wire, the wrong setting, or a thermostat placed in a draft or in direct sun can all throw off your comfort.
A dirty filter is one of the most common cold-weather furnace problems. It chokes airflow, strains your blower, and can cause your furnace to overheat and shut down. Typically, you should change your furnace filter every 90 days, more often if you have pets or allergies.
The heat exchanger keeps combustion gases separate from the air you breathe. Over time, it can crack from age and repeated heating and cooling. A crack can let carbon monoxide escape into your home, so if we find one, we’ll show you and explain your options.
Furnace Repair Cost in Toronto
The cost of furnace repair in Toronto depends on what’s broken, your furnace’s age and type, and when you need help. Across Ontario, repair costs generally fall into three ranges:
-
Minor repairs ($150 to $400): thermostat replacements and simple electrical issues
-
Mid-range repairs ($400 to $800): flame sensors and blower motor replacements
-
Major repairs ($1,500 or more): heat exchanger and control board replacements
After-hours emergency calls typically cost more than a standard daytime visit, and parts for older or discontinued furnaces can push the price up.
Whatever the repair, you’ll never be left guessing with Husky. We’ll give you the full price in writing before any work begins, so you can make the call that’s right for your home and your budget.
If repair costs are climbing toward half the price of a new furnace, we’ll tell you honestly and help you weigh repair against replacement.
Carbon Monoxide & Your Furnace
Carbon monoxide (CO) is an odourless, colourless, and tasteless gas. Small amounts can make you sick, and large amounts can be deadly. Gas furnaces are one of the most common sources of CO in the home, especially when a heat exchanger cracks or a vent becomes blocked, damaged, or disconnected.
The risk is far greater than people think. Over 65% of CO-related injuries and deaths in Ontario occur in the home. According to the Ontario Association of Fire Chiefs, about 88% of homes have something that poses a CO threat, and more than 50 people die from CO poisoning in Canada every year, most of them while sleeping, including an average of 11 in Ontario.
Ontario’s CO Alarm Rules Changed in 2026
As of January 1, 2026, Ontario’s Fire Code requires a working CO alarm on every storey of your home if you have a fuel-burning appliance like a gas furnace, including storeys without bedrooms.
If you’re not sure your home is covered, we can help you choose and install a carbon monoxide alarm for every level.
What to Do If Your CO Alarm Sounds
- Get everyone, including pets, out of the house right away.
- Call 911 from outside the home.
- Don’t go back inside until emergency services say it’s safe.
- Before using your furnace again, have a TSSA-licensed technician inspect it.
It’s also worth knowing the signs and symptoms of a carbon monoxide leak, such as headaches, dizziness, and nausea that ease when you leave the house.
Prevention Starts With an Annual Inspection
A CO alarm warns you about a problem. An annual furnace inspection helps stop problems before they start. During every tune-up, we check your heat exchanger, venting, combustion, and CO levels, catching small issues long before they put your family at risk.
How Long Do Furnaces Last?
If you’ve recently moved into an older house, or if you’ve been in yours for many years, your furnace may have seen better days. Deciding whether to repair or replace your furnace can be tricky, especially since you already have plenty of expenses as a homeowner.
If you’ve been keeping up with annual furnace maintenance, you can expect your furnace to last 15 to 20 years. The best thing you can do is watch for problems and address them before they get worse.
Furnace repairs are more affordable than buying an entirely new unit. Find out more about how long furnaces last.
If your furnace is showing some of the problems above, treat them as a warning sign. Schedule furnace repair as soon as you can to keep your furnace running for many more years.
Dangers of DIY Furnace Repair
There are plenty of good reasons to be a DIY homeowner, at least for some things. Saving money, learning a new skill, or the satisfaction of doing it yourself are all great reasons to tackle a household project.
1. Mistakes Can Expose You to Danger
Repairing furnaces and air conditioners means working with complex, potentially hazardous components and processes. Natural gas is the most popular way to heat a home in the GTA, and 67% of Ontario households use natural gas as their primary heating source.
Add in ozone-depleting refrigerant (under Ontario law, only certified technicians can handle), electrical wiring, ventilation, and the risk of explosion or carbon monoxide leakage … oh my!
If you don’t know exactly what you’re doing, it’s easy to make a mistake. And the consequences could be dangerous, even deadly.
2. You Risk Voiding Your Warranty
Take a look at your appliance warranties. Most likely, they’ll remain valid only if you can prove that a qualified HVAC professional did all furnace or air conditioning repair and maintenance work. Is saving a few bucks with DIY really worth voiding your warranty?
3. Repair Could Take Too Long
Let’s face it: Vaughan’s climate can be harsh, summer or winter. No matter the season, you and your family don’t want to be without heating or cooling for more than a few hours at most.
The problem is, as an amateur … er, that is … do-it-yourselfer, it’s likely to take you a lot more time to figure things out than a professional technician. And that’s even truer when HVAC replacement, rather than repair, is required.
4. You Might Not Restore the HVAC to 100% Efficiency
Okay, so maybe you’ll actually be able to complete the DIY fix and get your HVAC system running again. However, it might not work at 100% efficiency like it used to. As a result, it’ll end up costing you more on your monthly utility bills. “Cheap is expensive,” Grandma always said.
Things to Check on Your Furnace Before You Call Us
Please don’t open your furnace to examine it yourself. You need training and licensing to do this safely. That being said, there are a couple of “gotchas” you can quickly check:
- Your thermostat is set to “heat.” This can be an issue for new homeowners in the fall.
- The power switch on your furnace is set to “on.” Your furnace needs electrical power to run, and this switch cuts power in an emergency or when a technician is working on it. You can accidentally turn it off. Check the side of the furnace or the wall near it.
- The circuit for your furnace is on in your electrical panel. If you’ve had electrical issues, it may have tripped. If it trips again, the issue may be with the furnace or the electrical wiring.
Other issues, like blocked furnace vents or dirty filters, can cause temporary problems, but it’s best to call us for safety and repair reasons.

Why is my furnace blowing cold air?
The most common causes are a thermostat set to “fan on,” a dirty filter, an ignition or pilot light problem, or a gas supply issue. Check your thermostat and filter first. If it’s still blowing cold, give us a call.
How long should a furnace last in Ontario?
With annual maintenance, most furnaces last 15 to 20 years. Skipping tune-ups can shorten that, especially through our long Ontario heating seasons.
When should I replace my furnace instead of repairing it?
If your furnace is over 15 years old and breaking down often, or if a repair would cost more than half the price of a new furnace, replacement is usually the smarter choice. We’ll give you honest advice either way, and help you find the right new furnace for your Toronto home.
Are your technicians licensed in Ontario?
Yes. All of our technicians are fully licensed in Ontario, TSSA-licensed for gas work, and NATE-certified. They’re all members of our own team. We never use subcontractors.

Can a furnace cause a carbon monoxide leak?
Yes. A cracked heat exchanger, blocked venting, or poor combustion can all let CO into your home, which is why annual inspections and working CO alarms matter.
